Abstract
The purpose of this study was to investigate the effects of weight loss on exercise related circadian rhythm and exercise performance in wrestlers. Fifteen subjects participated in this study and measured leg strength(Cybex test), anaerobic power(Wingate test), V̇O2max(Bruce protocol) at 07:00hours and 17:00hours during before and after weight loss. All subjects reduced approximately 6% of their body weight during 15days by fluid and energy restriction and forced sweating. Anaerobic power(average power) and strength(extension peak torque) presented higher levels of 17:00hours than 07:00hours but after weight loss this daily exercise rhythm abolished. Weight loss reduced maximal aerobic running time and muscle endurance capacity. In conclusion weight loss was partially disordered exercise related circadian rhythm and reduced exercise performance. Abolished circadian rhythm was not directly related by reduced exercise performance after weight loss. Further study needed to elucidate the exact mechanism related to different weight loss period and amount.
