Featured Publications: Branched-chain amino acids, arginine, citrulline alleviate central fatigue; prevent perceptual-motor decline

Congratulations to our clients on their recent publications!

Dr. Chen-Kang Chang and team studied the effects of branched-chain amino acids (BCAA), arginine, and citrulline supplementation on central fatigue. Between periods of intensive Taekwando exercise, they measured the premotor reaction time of athletes who were given amino acid (AA) supplements versus those who received a placebo. They also measured the ratios of free tryptophan to BCAA, since tryptophan is a precursor to serotonin– a molecule that may be responsible for lethargy when present in high levels.

This paper was published in the Journal of the International Society of Sports Nutrition. To see how AA supplementation affected central fatigue, click here to read about it!

Dr. Chang and team also studied the effects of AA supplementation on tennis players’ perceptual motor performance. They provided the subjects with either the AA supplements or a placebo one hour before starting tennis matches. They measured the accuracy and consistency that the players hit the tennis balls with, along with the players’ tryptophan levels.

This second paper was published in the Scandinavian Journal of Medicine & Science in Sports. Click here to see how AA supplementation affected tennis players’ perceptual motor performance!

Mediomics Bridge-It Tryptophan Assay Kit was used in the study to measure the concentration of plasma free tryptophan.
