About this study

Official title: Relationship Between Sleep Time and Quality With the Production of Force, Power, and Muscular Endurance.

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).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean velocity at different %1RM

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

    Measured: Through study completion, an average of 4 weeks

  2. Peak velocity at different %1RM

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

    Measured: Through study completion, an average of 4 weeks

  3. Mean power output at different %1RM

    Measuring during bench press and back squat exercises.

    Measured: Through study completion, an average of 4 weeks

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

    Measuring during bench press and back squat exercises.

    Measured: Through study completion, an average of 4 weeks

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

    In bench press and back squat exercises

    Measured: Through study completion, an average of 4 weeks

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

    In bench press and back squat exercises

    Measured: Through study completion, an average of 4 weeks

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

    In bench press and back squat exercise

    Measured: Through study completion, an average of 4 weeks

  8. Resting Metabolic Rate (RMR)

    Kcal at rest measuring a metabolic chart

    Measured: Through study completion, an average of 4 weeks

  9. Maximal Fat Oxidation Rate

    g/min using a metabolic chart

    Measured: Through study completion, an average of 4 weeks

Secondary outcomes (5)
  1. Physical activity (METs-min/wk)

    Using IPAQ

    Measured: Before each trial, during the 4 weeks

  2. Dietary habits (g/kg of macronutrients)

    Using a 24-total recall

    Measured: Before each trial, during the 4 weeks

  3. Fat mass

    Using electrical bioimpedance (kg and % of body mass)

    Measured: Through study completion, an average of 4 weeks

  4. Fat-free mass

    Using electrical bioimpedance (kg and % of body mass)

    Measured: Through study completion, an average of 4 weeks

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

    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.

    Measured: Through study completion, an average of 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Sleep deprivation and Sleep place in people with Sleep Deprivation, run by University of Alcala at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean velocity at different %1RM (time frame: Through study completion, an average of 4 weeks). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 May 2025; AzTrials last refreshed its copy on 28 Oct 2026.
