Abstract

Seven heaUhy young male athletes exercised to exhaustion on a cycle ergometer after ingesting either the salts of aspartic acid or a placebo. Previous research has suggested that these salts can increase the capacity to perform muscular work by affecting circulating ammonia levels. The work test was performed at 75% of the subject’s V02titx after ingestion of 10 g of potassium-magnesium aspartate over a 24 hr period or a similar amount of a placebo. A double blind protocol was utilized. The time to exhaustion was significantly increased following aspartate ingestion, 87.6± 4.3 min vs. 75.7 ± 11.9 min in the placebo condition (p
