Sleep and Resistance Exercise

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).

Primary outcomes

  1. Mean velocity at different %1RM

    Time frame: Through study completion, an average of 4 weeks

    Measuring bar mean velocity desplacement during bench press and back squat exercises.

  2. Peak velocity at different %1RM

    Time frame: Through study completion, an average of 4 weeks

    Measuring bar peak velocity and time to reach peak velocity of bar desplacement during bench press and back squat exercises.

  3. Mean power output at different %1RM

    Time frame: Through study completion, an average of 4 weeks

    Measuring during bench press and back squat exercises.

  4. Peak power output and time to reach peak power output at different %1RM

    Time frame: Through study completion, an average of 4 weeks

    Measuring during bench press and back squat exercises.

  5. Number of repetitions performed at 65%1RM until task failure

    Time frame: Through study completion, an average of 4 weeks

    In bench press and back squat exercises

  6. Bar velocity deplacement performed in 1 set at 65%1RM until task failure

    Time frame: Through study completion, an average of 4 weeks

    In bench press and back squat exercises

  7. Power output generated in 1 set at 65%1RM until task failure

    Time frame: Through study completion, an average of 4 weeks

    In bench press and back squat exercise

  8. Resting Metabolic Rate (RMR)

    Time frame: Through study completion, an average of 4 weeks

    Kcal at rest measuring a metabolic chart

  9. Maximal Fat Oxidation Rate

    Time frame: Through study completion, an average of 4 weeks

    g/min using a metabolic chart

Secondary outcomes

  1. Physical activity (METs-min/wk)

    Time frame: Before each trial, during the 4 weeks

    Using IPAQ

  2. Dietary habits (g/kg of macronutrients)

    Time frame: Before each trial, during the 4 weeks

    Using a 24-total recall

  3. Fat mass

    Time frame: Through study completion, an average of 4 weeks

    Using electrical bioimpedance (kg and % of body mass)

  4. Fat-free mass

    Time frame: Through study completion, an average of 4 weeks

    Using electrical bioimpedance (kg and % of body mass)

  5. Mood state (tension, depression, anger, vigor, fatigue and confusion)

    Time frame: 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.
