Effect of Dehydration on Sleep Quality, Cognitive Skills, and Electromyographic Responses in Combat Athletes

Recruiting now · Not applicable

Conditions studied: Dehydration, Weight Loss, Weight Cycling, Sleep

In brief

This study examines the effects of rapid dehydration-induced weight loss on combat athletes' sleep quality, cognitive skills, and isokinetic strength performance. The research documents both benefits and risks of weight-cutting practices for athletes, coaches, and medical staff in weight-class sports. Findings will guide safer weight management approaches and inform potential revisions to international weigh-in protocols, while contributing valuable insights to sports science.
