Summary

This study looks at how quickly losing weight through dehydration (using a sauna) affects combat athletes' sleep quality, thinking skills, and leg strength. Twelve athletes with prior weight-cutting experience will be monitored before and after losing 3% of their body weight. The goal is to understand the risks of this common practice and help develop safer weight management guidelines.
