Registration Number
NCT06606626
Lead Sponsor
University of Alcala
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).

Secondary Outcome Measures
NameTimeMethod
Physical activity (METs-min/wk)Before each trial, during the 4 weeks

Using IPAQ

Dietary habits (g/kg of macronutrients)Before each trial, during the 4 weeks

Using a 24-total recall

Fat massThrough study completion, an average of 4 weeks

Using electrical bioimpedance (kg and % of body mass)

Fat-free massThrough study completion, an average of 4 weeks

Mood state (tension, depression, anger, vigor, fatigue and confusion)Through study completion, an average of 4 weeks

Participants graded a set of 29 items related to the mood on a Likert scale from 0 (not at all) to 4 (extremely) in reply to the question;How do you feel at this moment?; to assess six scales: tension, depression, anger, vigor, fatigue and confusion.
