Only 10% of the population is left handed, but more than 50% of star baseball players are southpaws. A study published in The Journal of the Royal Society Interface theorizes the discrepancy represents a fundamental difference between cooperation and competition.

According to researchers, cooperation favors same handedness, so people can share tools to build things everyone can use equally well. On the other hand, competition favors uniqueness, which is why a left handed fighter has an advantage over a right handed adversary.

True Strength Moment: There are sports that don’t favor the unusual. Consider golf, where only 4% of the top players are lefties. But where there’s a competitive advantage to be realized, true competitors are going to adapt in unusual ways. What’s the competitive edge keeping you on top of your game?

Physical performance goals often involve developing strength while losing excess body fat. L-carnitine, a compound biosynthesized from the amino acids lysine and methionine, can help you burn fat while augmenting exercise performance.

Research published in the journal Amino Acids showed that L-carnitine helps lower blood glucose levels so that fat is used as an energy source. Another study appearing in the Journal of Physiology found that daily supplementation coupled with carbohydrate ingestion resulted in less muscle glycogen being used during exercise.

To promote muscle hypertrophy, or growth, it’s generally recommended that you work with about 85% of your one rep max (1RM) and keep the reps in a range of between 6 and 8 per set. Of course, resistance training also helps promote bone density and a study published in the Journal of Strength and Conditioning Research looked at the ideal load for maximizing osteogenic potential.

The word ‘osteogenic’ relates to the formation of bone which many scientists believe is strongly influenced by the magnitude of training loads. Researchers recruited 12 subjects and had them perform back squats at 80%, 100% and 120% of their 1RM. A supermaxial load of 120% performed with a partial range of motion was determined to be best for developing bone density. It’s an interesting change up to any traditional routine, but be sure to bring a spotter to the gym if you want to try this.
