New research from the University at Buffalo suggests the thermal comfort of young men and women can vary during exercise and the recovery stage. Findings were published in the journal Medicine & Science in Sports & Exercise.
Ten men and 10 women in their early 20s rode a stationary bike at a low intensity while wearing a neck cooling device operated by the subject. Despite similar changes in skin temperature during exercise, female subjects wanted more cooling compared to their male counterparts.
During continued monitoring after exercise, the skin temperature of men gradually returned to normal levels in about 1 hour. Although their skin temperature returned to normal in about 10 minutes, women continued to desire more neck cooling, suggesting their core temperature remained elevated.
It’s not unusual to see athletes rolling different muscle groups across a foam cylinder. Is there anything to this practice, or is it just another fad? A study published in the Journal of Strength and Conditioning Research shows what foam rolling can and probably won’t do for recovering muscle groups.
Thirty-seven men raced forty 15-meter sprints. For the next 4 days, hip range of motion, hamstring muscle length, vertical jump height and agility were tested. Some subjects performed foam rolling each day before testing while others didn’t. Although there was no effect on hip range of motion, hamstring length or jump height, agility was less impaired in the foam rolling group compared to subjects who didn’t use this simple tool.
A physically fit man is typically stronger than women of the same level fitness, but women have the upper hand when it comes to muscle endurance. Consider the findings of a study from the University of British Columbia conducted in collaboration with the University of Guelph and University of Oregon.
Researchers had 8 men and 9 women matched for their levels of fitness flex their foot against an array of sensors 200 times as fast as they could. The speed, power and torque of their movements were recorded along with fatigue. Male subjects were faster and more powerful, but also fatigued more quickly than female subjects.
You’ve probably heard the term runner’s high. It’s usually associated with long distance running. The release of endorphins in the brain is behind this effect. A new study conducted at the University of Turku shows that endorphins are also released during High Intensity Interval Training (HIIT).
Using positron emission tomography, researchers determined that HIIT significantly increased the release of endorphins compared to a steady state moderate intensity 1-hour run. Scientists theorized this might help your body compensate for the physical and emotional stress of intense exercise.
You’ll find active adults with a variety of different goals working in the weight room to develop bigger muscles. If you’re in the game to get stronger, you might be interested in the findings of a study published in the journal Medicine & Science in Sports & Exercise.
Thirty-eight volunteers with no weight training experience took part in an 8-week program that included chest press and leg extension exercises. Some did a high-volume protocol involving 4 sets of reps to failure using their 8 to 12 rep max (RM). Others conducted a simple 1RM test where subjects attempted up to 5 maximal reps.
Although muscle size and endurance increased more for subjects in the high-volume training group, increases in 1RM strength were about the same for both groups.
People who love to lift typically don’t look forward to cardio day. That’s also the trend among runners and cyclists on the days they set aside for strength training. A study from the University of Utah looks into this separation of performance traits using lab mice.
Researchers observed how effectively some mice protected their territory by fighting off other mice. They also measured the running efficiency of mice using a treadmill.
Rodents that were successful fighters burned more oxygen while running compared to less successful fighters. Although there weren’t significant differences in body mass between runners and fighters, scientists theorized there might be small physiological differences.
You might have heard that stretching can have a negative impact on physical performance. Does this happen with all types of stretching, and how long does the effect last? A study published in The Journal of Sports Medicine and Physical Fitness offers insight into these questions.
Over the course of 3 days, researchers had 12 male taekwondo athletes sprint 20 meters before and after 3 types of stretching exercises: static, ballistic and proprioceptive neuromuscular facilitation (PNF). Sprint times increased after all types of stretching, and the effect lasted for 15 to 20 minutes with static and PNF techniques. Sprint times recovered after only 5 minutes with ballistic stretching.
As a general rule, you should allow at least 48 hours for each muscle group to recover from weight training. Exercising different muscles on different days is one way to work around this schedule, but a study published in the Journal of Strength and Conditioning Research suggests super sets might require a different approach.
Twenty-five physically active men performed 5 sets of 8 to 10 reps max on 4 different exercises: 2 targeting the legs and 2 for the shoulders. Some did super sets while other subjects separated these exercises. Super sets generated higher muscle activity as well as markers of muscle damage. Researchers concluded that 5 days was not enough time for complete muscle recovery.
Nitrates and other nitric oxide supporting ingredients are popular components of many sports nutrition supplements. What can they do for your weight room workout? A study published in the Journal of Strength and Conditioning Research put nitrates to the test using a dozen recreationally active men on the bench press.
Some subjects were given 400 mg of nitrate while others got a placebo before performing 3 sets to failure using 60% of their one rep max. All got 2 minutes of rest between sets. Even though there were no real differences in ratings of perceived exertion or lactate buildup, nitrate supplementing subjects did significantly more reps to failure and lifted a greater total amount of weight.
Back in 1963, researchers found that substituting while bread with bread containing 140 grams of rolled oats lowered LDL cholesterol. Now a meta-analysis of 58 controlled trials published online in the British Journal of Nutrition attempts to get more specific on the cardiovascular benefits of eating oat fiber.
Analyzing the diets of 4,000 subjects from around the world, researchers estimated that daily supplementation with 3.5 grams of beta-glucan fiber from oat could lower LDL cholesterol by an average of 4.2%. Working some into your diet isn’t likely to tip the scale too much. One cup of cooked oat bran amounts to just 88 calories.
Insulin sensitivity is a condition where insulin can’t effectively regulate blood levels of the glucose the cells in your body use for energy and other functions. Since a couple hours of moderate intensity exercise actually increase blood sugar levels, a University of Michigan study published in the journal PLOS ONE looks into the impact of diet.
Thirty two healthy women were fed meals where either 30% or 60% of the calories came from carbohydrates. After the 3rd meal, subjects in the low carb group showed a 30% reduction in insulin resistance. There was no reduction in the higher carb group, and the amount of carbs they consumed was within the range of Department of Health and Human Services recommendations…
Low levels of testosterone can lead to fatigue as well as decreased muscle and bone mass. Fortunately, your body’s natural production of this hormone can be altered through diet and exercise. A study presented at the Integrative Biology of Exercise 7 meeting in Phoenix, Arizona measured the effect of 12 weeks of aerobic exercise on 16 normal eight and 28 overweight men.
Researchers had subjects walk or jog for between 40 and 60 minutes per session performed 1 to 3 days per week. At the end of the program, overweight subjects had lost weight and significantly increased testosterone levels. Results were best in subjects who exercised vigorously. Normal weight subjects did not see such a dramatic testosterone increase.
Your body’s preferred fuel source for short bursts of intense effort is muscle glycogen. Consuming carbohydrates after exercise can help replace the glycogen used during a weight training workout, and a study published in the Journal of Applied Physiology provides insight into how you can optimize the process.
During the first 4 hours following exercise, glycogen resynthesis can be stimulated with 1 gram of carbohydrates per kilogram of body weight. So the carbohydrate consumption target for a 150 pound athlete would be around 68 grams. How you eat carbohydrates throughout the rest of the day should be geared toward meeting the demands of tomorrow’s training or competition.
New research reveals just how much protein you need after a workout to optimize muscle building.
The conundrum surrounding post-workout nutrition isn’t so much about what to eat as much as how much to eat. You and I both know protein needs to be a priority following a workout, but the jury is still out on how much protein is needed to maximize muscle growth and repair.
Fortunately, new research has shed some light on the matter. A study published in Physiology Reports sought to determine the impact of two different post-workout protein portions following exercise. Furthermore, it also sought to determine how varying amounts of protein post-workout influenced individuals with significantly different amounts of lean body mass.
Subjects were split into four groups as follows:
- Low Lean Body Mass (LLBM), 20 grams of whey protein
- Low Lean Body Mass (LLBM), 40 grams of whey protein
- High Lean Body Mass (HLBM), 20 grams of whey protein
- High Lean Body Mass (HLBM), 40 grams of whey protein
Each group received their protein following two total-body workouts.
Researchers observed a 20 percent greater uptick in post-training muscle-protein synthesis in subjects consuming 40 grams of whey protein compared to those consuming 20 grams. What didn’t make much difference was whether the subjects had low or high lean body mass.
As long as they had the higher amount of protein, they tended to experience a greater degree of muscle- protein synthesis.
How To Eat 40 Grams Of Protein Post-Workout
Although this study was small and the first of its kind, the results suggest that striving to consume 40 grams of protein post-workout is the way to go if you want to add muscle, regardless of your size. The authors speculate that this is especially true if you follow a total-body training style.
That’s because more muscle breakdown is occurring throughout the body compared to a single-body-part split. “Speculate” is the operative word, though. Single-body-part splits were not included in this study.
Rather than having to face two monstrous chicken breasts after your workout, consider one of these seven muscle-building meal combinations to meet your post-workout protein quota!
- 3/4 cup plain Greek yogurt + 1 scoop whey protein + 1/2 cup blueberries = 43 g protein
- 6 oz. salmon fillet + 1 cup quinoa + 1 cup broccoli = 45 g protein
- 4-oz. can albacore tuna + 1/2 cup canned navy beans + 2 cups baby spinach + 1 cup cherry tomatoes = 43 g protein
- 1 cup cottage cheese + 4 tbsp hemp seeds + 1 cup chopped pineapple = 42 g protein
- 6 oz. chicken breast + 1 cup brown rice + 2 cups baby kale = 42 g protein
- 6 oz. sirloin steak + 1 medium sweet potato + 2 tbsp pesto = 40 g protein
- 1 cup low-fat milk + 1/2 cup low-fat plain yogurt + 1 scoop whey protein powder + 1 tbsp almond butter + 1 frozen banana = 44 g protein
- Macnaughton, L. S., Wardle, S. L., Witard, O. C., McGlory, C., Hamilton, D. L., Jeromson, S., … & Tipton, K. D. (2016). The response of muscle protein synthesis following whole‐body resistance exercise is greater following 40 g than 20 g of ingested whey protein. Physiological Reports, 4(15), e12893.

You can sprint intervals, cycle in intervals, even incorporate resistance into your interval training. For those who want to try something new and different, a study published in the Journal of Sports and Conditioning Research looks at what you can achieve from interval training in an Olympic sized pool.
Scientists assigned 24 former competitive swimmers to swim freestyle intervals at 50 meter or 100 meter distances. The 50 meter swimmers did 12 to 16 bouts with 15 seconds of rest between each. The 100 meter swimmers did 6 to 8 bouts and got 30 seconds in between.
After 8 weeks of training, both interval distances improved 100 meter and 400 meter swimming performance with increased stroke length and greater maximal aerobic speed. There were no significant differences between groups, and 50 meter sprint times remained unchanged.
When you’re cutting calories, you’re likely to lose weight. But some of that weight is going to come from lost muscle mass rather than body fat. A study published in the journal Medicine & Science in Sports & Exercise suggests a tactic that can help preserve muscle mass while trying to shed body fat.
Researchers put overweight inactive women on a calorie restricted diet, enrolled them in an endurance exercise program or both protocols for just over 16 weeks. Calories were reduced by 10% to 20% and endurance exercise amounted to 7.4 hours a week for the exercise only group or 4.4 hours per week for the exercising calorie cutters.
All groups ended up losing around 7% of their original body weight, and the calorie restriction group lost about 2% muscle mass. The calorie reducing exercise group only lost around 1% muscle mass and the exercise only group didn’t lose any.

Back in 1953, researchers discovered that London bus drivers had a greater risk of developing cardiovascular disease than conductors working the same bus. It was the difference between sitting all day and moving around. A new study published in The Lancet looks into the level of exercise needed to negate the effects of driving to work and sitting at a desk 8 hours a day.
Scientists analyzed 16 studies involving more than 1 million adult subjects and grouped them by level of daily exercise. They found that 60 to 75 minutes of moderate intensity exercise per day was enough to make up for the risk created by being inactive for more than 8 hours a day.
Cutting down for summer or a physique contest is one thing. Researchers from the Leibniz Institute on Aging – Fritz Lipmann Institute in Jena, Germany found that cutting calories long-term can have both positive and negative consequences, as a study published in the Journal of Experimental Medicinesuggests.
A few years back, scientists were able to extend the lifespans of worms, fruit flies and lab rats through caloric restriction. Sometimes they lived 50% longer than normal. More recently, tests on mice showed that 30% food restriction slowed the aging of stem cells while reducing production of blood cell lymphocytes used for immune defense up to 75%
Got a busy day ahead of you? Fuel up with a healthy breakfast and make sure you get a fair share of protein. A study on obese and normal weight children published in The Journal of Nutrition suggests protein at breakfast can increase both energy expenditure and fat oxidation.
Some subjects were fed a breakfast with a macro-nutrient distribution of 21% protein, 52% carbohydrates and 29% fat while others sat down to a meal of 4% protein, 67% carbohydrates and 29% fat. The average rate of fat oxidation for all subjects was 16% higher with the high-protein breakfast, and overweight children burned more energy in the 4 hours following the high-protein meal.
True Strength Moment: Because approximately 1 out of 3 children between the ages of 2 and 19 are considered obese, this is important research. Subjects also reported a greater feeling of fullness after the high-protein breakfast, even though all subjects consumed about the same amount of food at a buffet later in the day.
When training for muscle gain we push our bodies to places they haven’t been before. The structure of our routine changes – weights increase and the intensity of workouts increases too.
We understand that in order to build muscle and size we must create a stimulus that challenges us, causing our muscle fibres to breakdown, repair and adapt (grow). Training within our comfort zone will only allow us to maintain our existing level of strength and fitness. By placing more demand on our bodies, it becomes paramount that we are eating the correct foods and taking the right supplements to promote the process of recovery.

Active adults who train intensely typically choose complete proteins containing all of the Essential Amino Acids to kick-start recovery. A new study from the University of East Anglia found a correlation between regular consumption of 7 amino acids from meat, fish, dairy, beans, lentils, broccoli and spinach, and cardiovascular health.
Examining data on 2,000 normal weight women in the TwinsUKregistry, researchers found evidence that higher consumption of these amino acids might be associated with lower blood pressure and less arterial stiffness.
True Strength Moment: The 7 amino acids singled out in this research were arginine, cysteine, glutamic acid, glycine, histidine, leucine and tyrosine. An interesting mix of Essential, Conditionally Essential and Non-Essential amino acids.

Consuming a lot of white bread, white rice and sugar sweetened soft drinks can go to your waistline, and research from Columbia University Medical Center suggests it can also weigh heavily on your mood. Analyzing data from 70,000 older women who participated in the National Institutes of Health Women’s Health Initiative Observational Study between 1994 and 1998, researchers found that consuming highly processed carbohydrates can elevate the risk of depression.
True Strength Moment: Highly refined carbohydrates elevate blood sugar levels. If the level gets high enough, your body releases hormones to try and reduce blood sugars. This hormonal response can have an impact on mood and fatigue. For a tip on potentially lifespan extending foods, read today’s Performance Blog at ABBperformance.com
Most active adults supplement creatine to build muscle size, strength and power. Numerous studies have shown creatine monohydrate to support these goals, and research recently published in the journal Medicine & Science in Sports & Exercisesuggests the ingredient might also support bone mineral density in older adults.
Forty-seven older women supplemented with 0.1 gram of creatine per kg of body weight or a placebo while training with weights 3 days each week. After a year, subjects who used creatine showed a reduced rate of lost bone mineral density and greater bone bending strength compared to placebo.
In addition to improved bone health, subjects who supplemented with creatine increased bench press strength by an average of 64% compared to 34% for subjects who were given a placebo.
Carnitine is synthesized from the amino acids lysine and methionine. Many active adults use it in supplemental form, but its impact on exercise performance isn’t well understood. Research published in the journal Cell Metabolism shows how this popular ingredient works with an enzyme called carnitine acetyltransferase, or CrAT, to increase muscle stamina in mice.
Scientists created a group of mice with CrAT deficiency in skeletal muscle. Compared to normal rodents they tired of exercise earlier. Then both groups were supplemented with carnitine. As expected, there was no change in the CrAT deficient mice. But the normal mice showed an even greater tolerance for exercise.
True Strength Moment: Researchers think that carnitine works with the CrAT enzyme to optimize muscle energy metabolism in mice. How or even if this mechanism works in a similar way for humans is unknown.

Gains aren’t made in the gym. That’s where muscle tissue is broken down. Size and strength is built up when your muscles recover from the breakdown of resistance training. So how long does this process take? A study published in the Journal of Strength and Conditioning Researchsuggests the duration might vary between exercises.
Sixteen men in their mid-20s with significant weight training experience performed 8 sets of preacher curls with one arm and seated rows with the other using 10 reps max resistance. Peak torque decreased 15.1% for multi-joint exercise and completely recovered 24 hours post-workout. The decrease was 26.8% after single-joint movements and peak torque remained 8.4% lower than pre-workout measurements 24 hours later. Delayed onset muscle soreness was also greater and took longer than 72 hours to recover for the single-joint movement.
True Strength Movement: This research shows the importance of changing up your training day to day. If you don’t give your muscles enough time to fully recover, you might be robbing yourself of some hard earned gains.

Doing cardio on an empty stomach, usually first thing in the morning, is supposed to help you burn more body fat than eating before your run, ride or swim. But is this scientific fact or just another popular gym myth?
A study published in the Journal of the International Society of Sports Nutrition compared the effects on 20 young female subjects who adhered to a hypocaloric diet for a month. Half of these subjects put in an hour of steady state cardio exercise 3 days a week without eating since the previous evening. The other half eat breakfast before training. All adhered to a diet designed to burn more calories than consumed. At the end of the program, both groups lost weight and reduced fat mass.
Conclusion: There were no significant differences between groups. As long as you’re cutting calories, having a small, balanced meal before training might outweigh the benefits of not eating first.
Everybody keeps track of their fitness journey in one way or another. If your benchmark is setting a new personal best, and you’ve reached a sticking point on squat performance, a study published in the Journal of Strength and Conditioning Research offers a variable resistance warm up that might help you grind out a higher one rep max (1RM).
After determining squat 1RM for 16 recreationally active men in their mid-20s, on separate occasions these subjects returned to perform 2 sets of 3 reps using 85% of their 1RM with free weights or banded free weights where band tension generated 35% of the load. 1RM squat was then tested 5 minutes after this short workout. Variable resistance significantly increased 1RM on the final lift.
True Strength Moment: Band resistance potentiated maximal lift performance without changing knee angle or muscle activity. It only slowed the velocity of concentric and eccentric contractions. Give this technique a try to see if it can help boost your best effort on leg day.
Essential fatty acids help facilitate muscle growth in a number of ways. One such way is through the formation of eicosanoids –molecules which exert control over bodily systems such as immunity and inflammation, and act as molecular messenger in the CNS (central nervous system). Eicosanoids can also be classified into prostaglandins, leukotrienes and thromboxanes. Prostaglandins are of the most importance to muscle growth. They:
- Increase sensitivity to insulin
- Help maintain normal levels of testosterone – the primary, male androgen hormone
- Increase the body’s secretion of growth hormone
- Increase the synthesis of protein in muscle cells
These functions are critical to achieving muscle growth during intensive training. In addition, EFAs powerfully affect the formation of fat tissue and fat metabolism. All the Omega-3s increase the breakdown of body fat; they also encourage the body to burn stored fat as fuel.
Beyond the immediately apparent effects on muscle growth and body composition, essential fatty acids help reduce inflammation, heal injuries, speed recovery and strengthen the immune system (important when engaging in repetitive movement with heavy weights and physical exertion that can weaken immunity); and improve sleep, concentration, stamina, increase blood-oxygen levels and improve cardiovascular function (all of which lead to more effective and intense workouts).
Research shows that to maximize muscle growth, decrease body fat and improve general health, men may consume between 3 and 3.5 grams of EFAs from all sources (food and supplements) daily; women may consume between 2.5 and 3 grams from all sources daily.
Essential fatty acids are found in foods and supplements. The downside of food sources is that many (fish and fully pastured – grass fed – cattle being exceptions) are higher in Omega-6 than Omega-3.
Supplementing with Optimum Nutrition’s Flaxseed Oil or Fish Oil remains the easiest way to get your daily recommended value of EFA’s.
There are more than a few grams per pound and grams per kilogram protein recommendations out there for you to calculate. But an easier to hit target was presented in an education session at SupplySide West.
According to the research, the average daily protein recommendation of 0.8 grams per kilogram of body weight works out to around 50 grams a day for normal size adults. Because this represents the minimum amount of protein needed, it was recommended that less active adults get at least 90 grams of protein per day and very active adults aim for a total of 120 grams of protein per day.
True Strength Moment: Since we’re all a little different physiologically speaking, this generalized protein benchmark won’t likely produce the same results for everyone. It might be a good starting point for figuring out the best daily amount of protein for your needs. Try it out for a month or two, and adjust as needed to support 2014 goals.
You’ve probably heard that averaging less than 6.5 hours of sleep a night or getting more than 8.5 hours of sack time is associated with a higher percentage of body fat. A new study published in theAmerican Journal of Health Promotion confirms these findings while suggesting that going to sleep and waking up at a consistent time of day is a habit related to lower body fat.
Researchers studied the sleep habits of 300 female college students over several weeks. They found that subjects with more than 90 minutes of daily variation in their sleep and wake times tended to have more body fat than subjects who adhered to a schedule that varied less than 60 minutes day to day.
True Strength Moment: Training yourself to go to bed and wake up pretty near the same time each day is simple enough, and to increase the quality of your sleep keep the temperature of your bedroom low while making the environment as quiet and dark as possible. Regular exercise also contributes to sleep quality.

Taken between meals or before bed, we think you’ll agree that our slowest casein is the easiest to mix and most exceptional tasting anti-catabolic protein we’ve ever made.
High Intensity Interval Training is popular with active adults who appreciate an intense workout even when they’re short on time. The results can equal what you’d get out of a less intense workout lasting twice as long. A study published in the journal Medicine and Science in Sports and Exercise examines what added intensity brings to your game.
Researchers had inactive female subjects in their mid-20s engage in high or moderate intensity interval training on a stationary bike. The high intensity workout was performed at 80% to 90% of capacity while moderate cycling was restricted to 60% to 80% of maximum effort. All subjects completed six and ten 60-second sets separated by active low intensity recovery. They trained three times weekly for a total of 12 weeks. Fat oxidation was more dramatically increased with HIIT, but neither group realized significant improvements in body weight, fat reduction or waist circumference.
True Strength Moment: The study brief didn’t mention anything about diet, so it’s hard to know what these subjects were eating during the 12-week program. Fat oxidation was increased for both groups, so that’s a positive development. Unfortunately, it only makes a difference if training efforts are complemented by sensible eating.
If you’re thinking a couple minutes of treadmill running can make up for a candy bar moment of weakness, some calculations from Harvard Health Publications HEALTHbeat might change your mind. That few minutes of enjoyment a typical candy bar brings will require about 45 minutes on the treadmill to erase.
The magic number is 3,500. This represents the number of calories in one pound of body fat. Walking or jogging burns about 100 calories per mile, so you’d have to put in 35 miles to lose one pound of body fat. That’s about 9 miles more than a marathon.
True Strength Moment: If this sounds discouraging, consider the power of calorie reduction. By cutting 250 calories out of your daily intake, you could lose a pound of body fat in a little more than a week just by walking for 30 minutes a day. Weight training helps increase your resting metabolic rate, so you burn more calories even when you aren’t exercising. Now you’ve got the needle moving in the right direction.
Many active people are focused on the amount of proteins, carbs and fat they consume each day. But you were told to eat your fruits and vegetables for the micronutrient support. Vitamins and minerals have important roles in numerous metabolic functions, and a study from Arizona State University suggests one micronutrient in particular can weigh in on weight loss efforts.
A group of 20 obese men and women were put on a calorie-restricted diet providing 40 mg of vitamin C daily, which is 67% of the recommended daily allowance. Half of these subjects were given a 500 mg vitamin C capsule each day while the rest got a placebo. All subjects lost an average of 9 pounds during the intervention, but those with higher levels of vitamin C tended to oxidize fat at a higher rate.
True Strength Moment: High levels of vitamin C didn’t accelerate fat burning, but low levels did appear to interfere with fat oxidation. Don’t let a lack of micronutrient support hold back your diet plans. If you aren’t getting a variety of fruits and vegetables in your diet, a high-potency multivitamin might provide you with nutritional insurance.
Creatine is an organic acid naturally produced in your body by amino acids. It supplies energy to all cells, especially muscle cells where it increases the formation of ATP. Protein is also composed of amino acids, and a study published in the Journal of the International Society of Sports Nutrition looks at the safety of creatine supplementation while adhering to a high-protein diet.
Subjects loaded creatine or a placebo by consuming 20 grams per day for 5 days followed by a 5 gram daily maintenance dose. They continued this supplementation routine for 12 weeks while sticking to a high-protein diet. Assessments of kidney function before, during and after the program revealed no significant differences.
True Strength Moment: This study adds to a mountain of research conducted over several decades. Creatine monohydrate ranks as one of the most studied sports supplements. It has consistently been shown to safely enhance muscle size, strength and power while assisting with exercise recovery.
There’s at least one type of completion where muscle mass holds back your performance. Even with greater strength and more muscle, sprinters can’t win a distance race against marathon-trained athletes. According to research published in the Proceedings of the National Academy of Sciences, these athletes are separated by a protein called PGC-1alpha.
Aerobic endurance-trained effort is fueled by oxygen. Anaerobic exercises like weight lifting and sprinting let muscle produce energy without oxygen. This leads to the buildup of lactate which results in fatigue. Endurance training stimulates the production of the PGC-1alpha protein which alters enzyme composition to reduce lactate production.
True Strength Moment: Both competitive and recreational athletes tend to plan their training around performance in a single sport. This research illustrates the metabolic changes training can produce. Of course, there’s nothing that says a sprinter can do some distance work. Marathoners might have something to gain in the weight room. Rounding our deficits in physical ability won’t hurt your performance.
Everyone’s favorite choice for energy is caffeine. Your options include coffee, tea, soda and performance beverages formulated for pre-workout use. Nutrient savvy athletes recognize carbohydrates as a reliable source of lasting energy, especially if you go with slowly digested complex carbs from sources like sweet potato, asparagus and brown rice. A study published in the journalSLEEP explored the impact of fats on energy.
According to researchers, protein didn’t affect energy levels, but fat consumption can decrease energy and alertness regardless of your age, gender, amount of daily caloric intake or body weight. A study of 31 healthy subjects aged 18 to 65 showed that fat consumption can weigh heavily on sleepiness even if you enjoyed a solid 8 hours of sound slumber the night before. Of course, your body needs healthy fats for a variety of functions. The trick is to avoid over-consumption.
The time you spend sleeping is also the longest your body goes without nutrition. This potentially catabolic situation is best handled with a slow digesting protein before bed and a high-protein meal in the morning to break this fast.
Cortisol is a catabolic hormone produced in response to stress, including intense exercise, and it can decrease amino acid uptake by muscle tissue. A study published in the Journal of Strength and Conditioning Research offers tips on controlling morning cortisol levels before competition.
Eleven swimmers had their cortisol levels measured upon waking on the day of an actual swim meet, and also on a pre-determined day with no competition scheduled. Although levels weren’t all that different day to day, cortisol tended to increase with feelings of tension and anxiety.
True Strength Moment: If you’re facing the best of the best, it’s only natural that you’ll feel some pressure in the build-up to competition. Athletes who train themselves to effectively control their emotions might also be able to dodge any potential side effects that elevated cortisol might add. Winning isn’t all in your head, but it takes more than muscle to succeed at the elite levels of any sport.
There’s an old saying about abs being built in the kitchen. Any bodybuilder can tell you that a commitment to clean eating goes well beyond maintaining a beach body 6-pack. Just be careful how much time you invest in food preparation. A study prepared by graduate students at Ohio State’s University of Public Health suggests there’s a tradeoff between time spent in the kitchen the how long you train at the gym.
Analyzing data on more than 112,000 adults who responded to the Census Bureau’s American Time Use Survey between 2003 and 2010, researchers determined that the average man spends 17 minutes preparing food and 19 minutes exercising. The average for women was 44 minutes of food preparation compared to 9 minutes of exercise. Every 10 additional minutes of food preparation raised the chance that you’ll decide not to exercise that day by 3%.
True Strength Moment: To save time and effort, you can prepare a week’s worth of meals all at one time. Store these small mini-meals in resealable containers or storage bags in your refrigerator before packing a day’s worth into a cooler. This helps eliminate restaurant temptations while leaving you with more time for training.
University of Michigan researchers exploring the relationship between muscle type and metabolism believe the white muscle built up through resistance training helps control blood sugars. An analysis of data published in the journal Nature Medicine suggests that a protein called BAF60c might play an important role in the formation of white muscle
Red muscle is prevalent in athletes who engage in long-duration endurance exercise. The mitochondria rely mostly on fat oxidation to generate ATP for energy. White muscle uses glycogen as the primary fuel source for short but intense bursts of power, which is why this type of muscle is prevalent in sprinters, body builders and weight lifters.
True Strength Moment: Although muscle type might play an important role in metabolism, your choice of carbohydrates can have a more immediate impact. To avoid the surge of energy and crash associated with fast-digesting sugary carbohydrates, choose complex carb sources like asparagus, sweet potato, oatmeal and brown rice. Consumed in small quantities at feedings spread every 2 to 3 hours apart, complex carbs can provide sustained energy to those who rely on strength and power.
A couple studies have shown that inspirational music can help you maintain intensity during a demanding cardio day. Now a study published in the Journal of Strength and Conditioning Research suggests that a catchy beat can positively influence short-term recovery – even without the music.
Ten recreationally active men in their mid- to late 20s ran all-out for 6 minutes on 3 separate occasions. During the first session, they recovered for 15 minutes with no soundtrack. The next time, motivational music was played, and after the final run only the beat from that same motivational music was played. Music and the beat increased activity during active recovery which lowered lactate levels as well as the perceived rate of exertion.
True Strength Moment: Although music worked slightly better than just a beat, both produced better results than non-structured active recovery. This might have something to do with the way most people unconsciously alter their pace to keep time with a tune. It appears that keeping your feet moving after an intense cardio workout improves both actual and perceived rates of recovery.
Glutamine has many direct and indirect effects on weight loss. Moreover, taking glutamine can improve your fitness level, body composition and overall health. Glutamine has powerful effects on the immune system, muscles, digestive tract, liver and brain. In fact, it is the single most abundant amino acid in your body. The glutamine that is synthesized in the body or ingested from food might not be enough for individuals who train frequently, endure chronic stress or have weakened immune systems
Glutamine also increases muscle volume by drawing water and carbohydrates into muscle cells. Glutamine boosts metabolism and fat burning. Not only does it increase fat burning when taken before and during exercise, it also boosts your resting metabolic rate. Glutamine’s effect on immune function helps you stay healthy so you do not miss workouts. By improving muscle recovery, glutamine allows you to hit the gym more frequently with less muscle soreness. Taking even small amounts of L-glutamine increases the secretion of growth hormone, which is a potent fat burning substance.

To achieve your goal of bulking up, please keep in mind that gains take time, perseverance and a synergistic routine of working out, eating well and correct supplementation. However, there are some core principles to keep in mind for weight gain:
- Make certain that you are consuming 1 gram of protein per pound of body weight per day from all sources. These should mostly be from whole foods and then supplementing accordingly to achieve your daily quota
- Do short, intense workouts
- Make certain you are getting adequate sleep
- Never miss a meal
Within the ON range are a number of products that can help you on your journey. We offer two weight gainers, either Serious Mass or Pro Complex Gainer. If you have a very difficult time gaining weight and are the type of person who just cannot get enough calories in a day, Serious Mass is for you. Otherwise, our lean gainer, Pro Complex Gainer, would be more appropriate. This product is intended to be taken between meals and/or before bed.
In addition, within any muscle building regime, Creatine plays a key role for strength and recovery. It’s available in two different formats: Creatine caps or Micronized Creatine Powder. These products, paired with a good multivitamin and balanced diet, will help you to reach your end goal successfully.
If your idea of cardio day is an hour-long jog or bike ride, a study published in The American Journal of Clinical Nutrition suggests supplementing with the Branched Chain Amino Acid (BCAA) leucine and other Essential Amino Acids (EAAs) can increase your body’s protein synthesis response during the recovery phase.
Researchers had 8 healthy adults cycle on a stationary bike for an hour at 60% of maximum capacity. All received a drink containing 10 grams of EAAs. Some contained 3.5 grams of leucine while others had only 1.87 grams of leucine. The increased concentration helped subjects realize a greater degree of protein synthesis during recovery.
True Strength Moment: Protein synthesis is one of the key mechanisms involved in building muscle size and strength. While all of the EAAs have a role in fueling this process, this study puts the BCAA leucine in the spotlight. A number of ON products offer BCAAs in a 2:1:1 ratio of leucine to isoleucine and valine.
What qualities separate the very best players from good ones? Work ethic, determination and natural ability, sure. But a study published in the journal Medicine and Science in Sports and Exercise suggests a player’s ability to rapidly act on visual cues might also factor into the top competitor equation.
Researchers recruited 8 elite soccer athletes along with 8 lower level players and had all take part in a soccer-specific drill where reactions to simulated opponents during match play were analyzed. While intermittent exercise improved visual and cognitive processes for both groups, the elite players displayed better anticipation by focusing on a greater number of areas in a shorter time span. The non-elite athletes didn’t process the action that quickly or accurately.
True Strength Moment: Is there a technique for teaching yourself to focus more quickly and accurately on opponents during competition? There are probably a number of different drills you could practice, but on-field experience might be the best way to gain the upper hand. It’s one of the reasons elite players spend very little time on the bench.
If you’re like most people, you probably dine out at restaurants 4 or 5 times each week. Those are the numbers aLivingSocial Dining Out Survey reported recently. Factor in an estimate made by the U.S. Department of Agriculture that adds 2 pounds per year for each additional meal eaten outside of your home’s kitchen, and you’ve got a weighty issue.
True Strength Moment: People who travel a lot don’t always have the option of preparing their own meals, but there are things you can do to keep restaurant food from adding too much flab to your frame. Don’t order fried foods, minimize the sauces and high-fat dressing, and keep portion size under control using visual cues. An amount between a deck of cards and your clenched fist is a sensibly sized portion.

Whether you were one of those kids who never ate your vegetables, or have become convinced as an adult that carbohydrate foods make you fat, there’s a lot to like about regular vegetable consumption — especially for active adults who are working hard to diet down for swimsuit season. Most garden vegetables are naturally low in calories and typically don’t contain a lot of sugar or fat either. Even though vegetables aren’t considered energy dense, most contain abundant amounts of micronutrients in the form of vitamins and minerals which can help your body more effectively process protein, carbs and fat.
In addition, vegetables tend to contain lot of dietary fiber and digesting all this bulky food forces your body to burn more calories. This quality makes fresh vegetables and excellent choice for any dieter, as long as you hold the salad dressing and other condiments to a minimum.
Most strength athletes focus their carbohydrate consumption on complex carbs like oatmeal, brown rice, whole grain bread and sweet potatoes. Broaden your selection to include broccoli, green beans and a colorful assortment of raw vegetables for salads, and you’ll benefit from low calorie nutrients along with plenty of filling fiber.
Among the many benefits of exercise is the way it helps you beat stress. But does that mean people who make a point of staying fit can handle stressful situations better? A study published in the journal Medicine and Science in Sports and Exercise suggests there may be some truth to that assumption.
Researchers assigned 8 subjects with a below average level of fitness and 8 very fit subjects to cycle on a stationary bike for 37 minutes at 60% of capacity. For the next trial, these same volunteers were given complex metal problems to solve while cycling for 20 minutes. Not only did the dual task increase anxiety for the less fit subjects, compared to their in-shape counterparts they produced greater amounts of the catabolic hormone cortisol.
True Strength Moment: Why are active adults who exercise regularly better able to handle difficult situations? These are the kind of people who are used to setting and achieving ambitious goals, so that could be a factor. Whatever the reason, their hormonal response to exercise makes it easier to recover and come back for more.
Pretty much anyone who’s into endurance exercise realizes the value of carbohydrate energy. But like strength athletes and their protein, there’s always the question of how much and what type produce optimal results. A study published in the journal Medicine and Science in Sports and Exerciseput different amounts of different carbs to the test using 51 cyclists and triathletes.
Trials started out with a 2-hour ride at 95% of capacity and finished up with a 20 km time trial. Subjects were told to post the fastest time possible. Carbohydrate drinks contained equal parts glucose, fructose and maltodextrin. Over 160 minutes of performance, researchers estimated that the optimal rate of consumption was 78 grams for every hour of effort.
True Strength Moment: To help your muscles recover from a cycling event like this one, you might consider ‘stacking’ that carbohydrate performance beverage with powdered protein. The relatively high BCAA concentration found in whey could help minimize the breakdown of muscle tissue during intense exercise.
Now that the holidays are over, it’s time to focus on getting into your best shape yet. Increasing your metabolism will help to burn excess body fat as you work hard in the weight room to build muscle. Here are some tips to help get your metabolism going strong:
Increase Training Intensity – Changing the look of your body requires more than fat loss. Developing muscle mass will play an important role in attaining this goal. To help the process along, try increasing your training intensity. This can be accomplished by adding more weight to the barbell or dumbbells, spending less time resting between sets or doing more reps.
Eat the Right Amount of Macronutrients — Your kitchen based efforts to lose fat and gain muscle will have to go well beyond cutting calories. It’s vital to eat the right amount of protein, carbs and fats. Getting enough protein (at least one gram for each pound of body weight) helps active adults recover from weight training. Balancing carbs and fats is also important for fueling exercise performance. Sticking to a low fat diet will allow for a moderate amount of complex carbohydrates.
Using Cardio Correctly – Adding moderate amounts of cardiovascular effort to your training program will help to reduce body fat, but it’s important not to overdo the cardio. Too much time on the treadmill or stationary bike can work against your efforts to build muscle. A good starting point is 3-4 days a week, beginning with 20-30 minute sessions.
There’s always been a lot of confusion about which protein to use, how much and when. The December edition of the Journal of the International Society of Sports Nutrition published a review of studies to determine the validity of previous research. The conclusions outlined here should be of interest to anyone with a goal of developing muscle hypertrophy (size) and strength.
The research suggests weight lifters interested in building muscle size should try to consume 1.2 to 2.0 grams of protein per kg of body weight per day. Since 1 kg equals 2.2 pounds, 1 gram per pound of body weight is about right for the upper end of this recommendation. You should also try to consume 44 to 50 calories per kg of body weight per day, which works out to 20 to 23 calories per pound.
Whether you choose to drink a protein shake pre- or post-workout, the study suggests you can expect increased physical performance, recovery, muscle mass and strength. When choosing a protein, make sure each serving includes 3 to 4 grams of the BCCA leucine to promote protein synthesis. A quality whey shake should meet that need, and combining it with a fast-digesting carb like glucose or maltodextrin helps modulate protein synthesis. Essential amino acids and dextrose work best when consumed pre-workout.
True Strength Moment: Now that you have a better idea of what nutrition support to use and when, the research concludes with a recommendation for experienced lifters looking to enhance muscle size and strength: Plan a weight training routine lasting at least 10 to 12 weeks around compound movements for both upper and lower body.
Betaine was included in Platinum Hydrobuilder, ON’s all-in-one muscle recovery formula, because regular use can promote exercise performance. A recent study published in the Journal of Physiology illustrated this point using lab rats supplemented with and without beetroot juice, which is a rich source of dietary nitrate, magnesium, potassium, vitamin C and betaine.
For 5 days, some rodents drank water with beetroot juice added while others drank plain tap water. A 20 minute treadmill run at a 5% incline showed supplemented rats had improved blood flow to fast twitch Type II muscles. Boosting blood and oxygen delivery to muscles improved exercise performance.
True Strength Moment: Improving blood flow to Type II muscle fibers can benefit both aerobic and anaerobic forms of exercise since IIb intermediate fast twitch fibers can use either metabolism to power your training.
Casein protein: An extremely slow digesting protein have demonstrated steady release of amino acids for an incredible 7 hours. While whey protein may increase protein synthesis to a very high degree, micellar casein is much more important in preventing muscle breakdown especially when taken before bed.
Glutamine: 61% of your skeletal muscle is glutamine! Glutamine is majorly depleted during intense training sessions decreasing body’s immunity. Supplemental glutamine prevents your muscle from being eaten up (catabolized) to provide glutamine to other cells of the body.
Anti-oxidants (Vitamins and Minerals): The post workout stress is highly catabolic. The free radicals released during the workout are highly unstable ions eating away the muscle tissue. Stabilizing them is the top priority to kick-start the anabolic process. Anti-oxidant nutrients like Vitamin C, Vitamin E, Zinc, Phytochemicals etc stabilize the free radicals and keep check on their catabolic effects, especially post-workout.
BCAAs: Branched chain aminos are excellent anti-catabolics. No matter what, in the process of energy production during workouts, these are definitely used. Providing specifically BCAAs ensures the body doesn’t take them from the existing muscle tissue, hence preventing muscle loss.
Setting up a circuit of resistance training exercises can provide you with a great workout while getting you out of the gym much faster than working a more traditional series of sets and reps. So can interval training, where you alternate between high and low intensity. Which works best? A study published in the Journal of Sports Science & Medicine tested several variations of this theme on eleven recreationally active women.
After determining individual strength and exercise capacity, subjects undertook three different training sessions on non-consecutive days. They engaged in circuit training with weights, aerobic circuit weight training and combined circuit interval training.
The program combining circuit and interval training produced the highest heart rates and levels of perceived exertion while also elevating blood lactate to the greatest degree. The next most challenging program was aerobic circuit weight training. Put these results to the test and take the ‘routine’ out of your current program.
Whey protein is popular with all types of athletes because, in addition to being a complete protein source containing all of the Essential Amino Acids, it digests rapidly so those aminos can go right to work supporting muscle recovery. How fast? A study published in the International Journal of Sport Nutrition and Exercise Metabolism compared the amino acid response of liquid protein sources to solid food.
Using two groups of trained and untrained volunteers, researchers determined that drinking a liquid form of protein like a whey shake helps you achieve peak blood levels of amino acids twice as fast as proteins from solid foods. Peak concentrations were reached in 50 minutes with liquids compared to 100 minutes when food needed to be digested.
True Strength Moment: Although total amino acid levels were similar across all protein sources, skim milk elevated concentrations of the BCAA leucine fastest, reaching a peak in just 25 minutes compared to all other foods. For more on the importance of this branched chain amino acid and the conditionally essential amino acid glutamine, read today’s Performance Blog post atABBperformance.com
Jump performance, including how well you can absorb energy from a landing, plays a critical role in just about any team sports competition. A study published in the journal Medicine and Science in Sports and Exercise suggests there are interesting physiological differences between male and female athletes.
Researchers measured lower body muscle mass along with the quad and hamstring strength of 70 active male and female subjects. They discovered that, from amount of amount of lean mass, you can predict how effectively the female knee joint will absorb energy on jump landings. Those lacking muscle mass can gain a performance advantage by developing maximal eccentric quad strength. Unfortunately, neither of these observations applies to men. For an interesting perspective on how men and women sweat during exercise, ready today’s Breaking News post atoptimumnutrition.com
