Conditions

Sleep Deprivation

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 maximal fat oxidation (MFO) in male and female participants.

Interventions
