摘要: Abstract The effect of L-carnitine supplementation on the plasma carnitine levels and various performance parameters seven male marathon athletes was investigated. Each athlete completed two progressive treadmill tests to exhaustion, separated by a six week period (2g L-carnitine/day). During peak running speed, oxygen consumption, cardiovascular responses, respiratory exchange ratio were monitored. After speed increased 5.68%, average consumption (VO 2 ) heart rate decreased, values showed declining tendency. acyl-, total- percentage bound significantly, whereas free but remained below normal range. Findings from this study suggest that could positively influence aerobic capacity.
