- 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
Name Time Method 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-free mass Through study completion, an average of 4 weeks Using electrical bioimpedance (kg and % of body mass)
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.
