Amino acid supplements are advertised to enhance performance in various groups of athletes. Based on the available research data, which of the following statements is FALSE concerning their effectiveness in this regard?

A. Arginine and ornithine are used to stimulate the release of human growth hormone, but research is generally not supportive of an ergogenic effect.

B. L-tryptophan has been shown to enhance performance in one study, but more recent data with better study designs have shown that L-tryptophan is not an effective ergogenic.

C. Some well-controlled research with aspartates has shown some possible beneficial effects, but more research is needed for confirmation.

D. BCAA supplementation is theorized to be beneficial in prolonged endurance events, but more research is needed for confirmation, especially with chronic supplementation.

E. Although not an essential amino acid, research conducted at Old Dominion University has shown inosine to be an effective ergogenic for aerobic endurance events.

A few people utilize branched-chain amino acids to forestall exhaustion and improve focus.
Athletes utilize branched-chain amino acids to improve exercise execution and diminish protein and muscle breakdown during exceptional exercise.
This is because the protein is one of the most famous dietary enhancements showcased to athletes and genuinely dynamic people. Protein supplements have been prescribed to athletes to improve nitrogen maintenance and increment bulk, to forestall protein catabolism during delayed exercise, to advance muscle glycogen resynthesis following activity, and to forestall sports pallor by advancing an expanded amalgamation of hemoglobin, myoglobin, oxidative chemicals, and mitochondria during oxygen consuming preparing.
Hence, the right answer is option e "Although not an essential amino acid, research conducted at Old Dominion University has shown inosine to be an effective ergogenic for aerobic endurance events."
