The Effect of Weight Reduction on Exercise Capacity, Immune Response of Taekwondo player

ABSTRACT

The Effect of Weight Reduction on Exercise Capacity, Immune Response of Taekwondo player. Exercise Science, 13(1): 65-76, 2004. The purpose of this study, was subjected to Taekwondo players weight reduction each time in 0%, 3%, 6%, 9% weight reduction for a week(two days intervals) so as to examine closely the effect on changes Aerobic Exercise Capacity, Immune Response to provide necessary data for the right weight reduction and improvement of play performance. The subjects were 8 Taekwondo players, who have excellent practical skills and have more than 6 years experience, executed weight reduction through the exercises, dietaries and exhalation of sweat as 'Y' university. The methods to measure Exercise Performance were cardiopulmonary endurance test by treadmill, Wingate test by Ergometer and the data were handled by repeated measure ANOVA and executed contrast test to analyze the differences each time of weight reduction. As reduced weight Maximal Anaerobic Power, Mean Anaerobic Power and Minimal Anaerobic Power were increased slightly in 3% weight reduction but it decreased significantly in 6% and 9% weight reduction. O2max decreased significantly in 3% and 6% weight reduction, Exercise Duration had a tendency to decrease each time weight reduction and decreased significantly between 0% and 9%. WBC Count was shown decreases with weight reduction by 6% weight reduction and slight increased in 9% weight reduction. B, T, Th/Ts ratio were increase by 6%, but slight decreased in 9% weight reduction. NKcell was decreased significantly by 6% and increased in 9% weight reduction. Therefore, In terms of Anaerobic Capacity are 3%, Aerobic Capacity and Immune Response are 6%(4kg) being considered of self-weight reduced body's best level for weight reduction in Taekwondo players.

Key words: Weight reduction, Exercise capacity, Immune response
