Effect of Rapid Dehydration and Rehydration on Work Capacity and Muscle Metabolism During Intense Exercise in Wrestlers

The Current State of Weight-Cutting in Combat Sports

“…The results of laboratory-based trials investigating the effects of weight-cutting on varying aspects of exercise performance are also mixed. Indeed, there is research suggesting that weight-cutting practices negatively influence repeat-effort performance [9,10,13,17,37], while other research indicates no impact on repeat-effort [11,19,20], aerobic [14], and anaerobic performance [38]. It appears that when larger magnitudes (>3% body mass) are lost rapidly (<5 h) using thermal strain, high-intensity exercise performance is impaired [9,13,17].…”

It appears that when larger magnitudes (>3% body mass) are lost rapidly (<5 h) using thermal strain, high-intensity exercise performance is impaired [9,13,17]. However, when a similar magnitude of weight is lost over multiple days (2–5) using a combination of methods (food restriction and body-fluid manipulation) laboratory-based trials have failed to observe any negative effect [11,19,20,38].…”

“…There has been a substantial but limited body of scientific research investigating the prevalence of weight-cutting in different combat sports [3,4,5,6], the different methods of weight loss [3,4,5,6,7,8], the influence on competitive performance [9,10,11,12], the physiological changes associated with weight-cutting [9,13,14,15,16,17] and methods to improve performance following weight-cutting [2,18]. Within this body of literature, there are conflicting findings on many of the topics mentioned above.…”

“…Within this body of literature, there are conflicting findings on many of the topics mentioned above. For example, studies have indicated that weight-cutting has a negative effect on exercise performance [9,10,13], while other studies have reported no effect [11,19,20]. The limited volume of literature across a range of topics within weight-cutting precludes a comprehensive systematic review which would use a highly technical, specific methodological approach to identify and appraise evidence on weight-loss practices in different combat sports [21].…”

Weight Loss and Weight Cycling in Amateur Wrestlers: Implications for Performance and Resting Metabolic Rate

“…Studies on wrestlers indicate thattotal recovery standard laboratory tests o t physical performance. In .those studies in which a decrement in performance was observed after weight loss, performance returned to normal after the recovery period (approximately 5 hrs) (23,37,45,50). Other studies showed no difference between the physical performance after weight loss and after nutritional recovery (35,58).…”
