Effect of Short Term Weight Reduction by High Intensity of Endurance Training on Body Composition, Muscle Mass and Functions in Male College Wrestling Athletes

Abstract

OBJECTIVES This study is aimed to investigate the effect of short term weight control by High Intensity Endurance Training(HIET) on body composition, muscle mass and functions male college in male wrestling athletes. METHODS Fifteen male college wrestlers with at least 5 years of career were participated and measured body composition, muscle mass and functions after weight reduction through 6 days of HIET intervention. RESULTS First, WRG (weight reduction group, n=7) showed significant changes after HIET -induced weight reduction in work fatigue at 60 degree/sec during flexion in elbow joints, it showed not significant changes after training-induced weight reduction in peak torque, avg. power, work fatigue at 60 degree/sec and 180 degree/sec during extension and flexion in elbow and knee joints. Second, CG (control group, n=8) showed no significant changes after training-induced weight reduction in peak torque, avg. power, work fatigue at 60 degree/sec and 180 degree/sec during extension and flexion in elbow and knee joints. CONCLUSIONS Taken together, relatively short-term, or 6 days weight loss with HIET may not negatively affect muscle mass and function and may be accompanied by fat loss. Additionally, compared to other short-term weight loss methods, this method would be better not only for wrestling athletes but also the weight division athletes. However, it is important to note that weight loss can partially induce muscle fatigue, and athletes should be prepared for a possible decrease in muscular endurance, depending on their individual characteristics.
