Effect of branched-chain amino acids (BCAA), glucose, and glucose plus BCAA on endurance performance in rats

Article Abstract:

Branched-chain amino acids (BCAA) and glucose may enhance endurance performance in rats. Saline administration, however, had no effect on performance. Rats received injections five minutes before treadmill testing. The average running time to exhaustion was higher in the BCAA and BCAA + glucose groups. Pre-exercise administration of glucose did not change this physiological effect. This finding supports the theory that carbohydrate availability during exercise is a consequence of BCAA administration.

Carbohydrate availability affects ammonemia during exercise after beta(sub.2)-adrenergic blockade

Article Abstract:

Evidence that carbohydrate availability affects ammonemia in exercise after beta(sub.2)-adrenergic blockade is presented. Mechanisms that bring reduction in exercise capacity in the presence of beta-blockers have not been explained until now, but may be related to metabolic effects. A study has been carried out using rats and a motor-driven treadmill.

The effect of BCAA supplementation upon the immune response of triathletes

Article Abstract:

Giving athletes branched-chain amino acids before prolonged intense exercise can prevent the decline in serum glutamine and interleukin-1 that normally occurs. This was documented in a study of 12 elite male athletes participating in a triathlon.
