Brief Summary

Introduction: Despite the awareness of the importance of sleep in our lives, especially for athletes, the consequences of poor rest on sports performance are not well understood. Furthermore, the interaction between complete and partial sleep deprivation over one night and sleeping the usual hours for each person remains unclear. Objectives: The aim of this study is to evaluate the effects of sleep deprivation on the production of strength, power, and muscular endurance according to sex (men vs. women) and type of exercise (bench press vs. squat). Additionally, the study will analyze the effects of sleep deprivation on perceived fatigue, mood, dietary habits, electrical activity, resting metabolic rate (RMR), and maximal fat oxidation (MFO).
