The purpose of the present study was to determine the effect of maximal exercise on anaerobic threshold,, blood lactate, LDH concentrations and EMG activities change in man artistic gymnasts. Twenty-one healthy, artistic gymnasts. Artistic gymnasts were divided in to business team(n=7), university team(n=7) and high school team(n=7). All subjects completed 3-min stage graded maximal treadmill exercise with bruce protocol. Bruce protocol was applied to collect the data for the anaerobic threshold, blood lactate, LDH concentrations and EMG activities. Blood samples were collected at pre, immediately after exercise and recovery 60 min. All data were presented as means ± standard deviation. There was significant differences in anaerobic thresholds measured by AT-% VO , AT-VO(㎖/㎏/min), AT-out time(min). The changes of AT-% VO , AT-VO(㎖/㎏/min), AT-out time(min) showed significantly difference between times and groups. The changes of blood lactate, LDH concentrations showed significantly difference between times and non significantly difference between groups. The changes of Surface EMG(vestus medials and vestus laterals) activities showed not significantly difference between times and groups. In the present results, It can be suggested that acute maximal exercise can influence on metabolic functions following individual working ability, muscle mass and exercise carrier difference.
