EATING OATS CAN REDUCE CHOLESTEROL



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.

FEWER CARBS CUTS INSULIN RESISTANCE



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…

How Much Protein Should You Consume Post-Workout?

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.[1] 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:

  1. Low Lean Body Mass (LLBM), 20 grams of whey protein
  2. Low Lean Body Mass (LLBM), 40 grams of whey protein
  3. High Lean Body Mass (HLBM), 20 grams of whey protein
  4. 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

INTERVAL TRAINING FOR SWIMMERS



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.

How To Beat 8 Hours of Sitting


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.

START YOUR DAY WITH PROTEIN


10-beginners-fitness-mistakes-youll-never-make-again-5
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.

RISKS OF HIGHLY REFINED CARBS


refeeds-for-fat-loss-the-science-behind-leptin-graphics-4
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
