L-GLUTAMINE SUPPLEMENTATION: EFFECTS ON ENDURANCE, POWER AND RECOVERY

The purpose was to examine the influence of L-Glutamine on endurance and power. Cardio-respiratory capacity (VO^sub peak^) was determined in 12 men using a cycle ergometer. After 2 days, subjects performed 3 Wingate tests to assess total revolutions (TR), peak (PP) and mean Power (MP); and a time trial to exhaustion (TTE). Two Wingates were conducted before and immediately after the TTE, the third after 24hrs. Subjects were then randomized to either L-glutamine (GLU) or placebo (CON) for 6 days. After 6 days all tests, except the VO^sub peak^, were repeated. There were no group differences for VO^sub peak^, power indices, and TTE before supplementation. Both groups showed a similar drop in power (TR:-22%; PP:-27%; MP:-27%, p
