Study summary

Sleep is essential to human health and well-being. Lack of or poor sleep can negatively impact cognitive function, mood, and physical performance. Athletes, especially elite athletes, are at risk for sleep problems due to heavy training schedules and the stress of travel.

Lack of or poor sleep can negatively impact athletes in many ways, including lack of sleep can lead to mood disorders such as irritability, anxiety, and depression. This may have a negative impact on athlete motivation and participation in training. Sleep deprivation can lead to decreased muscle strength, endurance, and coordination. This can affect an athlete's performance in training and competition phase.

Sleep hygiene refers to a set of practices aimed at regulating the sleep environment and habits to improve sleep quality. Sleep hygiene education is an intervention designed to teach athletes about the importance of sleep hygiene to improve their sleep quality. As sleep quality improves, attention, concentration, memory, and decision-making skills also improve . This can help athletes to perform better during training and competition. As sleep quality improves, mood disorders such as irritability, anxiety, and depression decrease. This can increase athlete motivation and participation in training. As sleep quality improves, so does muscle strength, endurance, and coordination.

Read the detailed description

This study will be one of the first study conduct on human to examine the effectiveness of sleep hygiene education among gymnasts. Gymnasts, like other athletes, are prone to sleep problems for the reasons mentioned above. Therefore, it is of great significance to study the impact of sleep hygiene education on the sleep quality of gymnasts and indirectly on sports performance and sleep health as well as its underlying mechanisms. Additionally, this study has the potential to make a significant contribution to the field of exercise science by examining the effectiveness of sleep hygiene education, specifically among gymnasts. By examining effects on sleep quality, athletic performance, and sleep health, this study could provide valuable insights into developing targeted interventions to optimize sleep and health in gymnasts.

The duration of the measurements will be in week 1 to see the acute effects of sleep, and as a minimum of 18-21 days is required for behavioural change, sleep measurements will be made in week 4.

What researchers measure

Primary outcomes

  1. Actigraphy

    Actigraphy is a less invasive method compared to other sleep measurement methods such as polysomnography

    Time frame: Pre-test, following one week mid-test and following one month post-test

  2. Athlete Sleep Behavior Questionnaire (ASBQ)

    Athlete Sleep Behavior Questionnaire is a 17-item, Likert-type (1- Never, 5- Always) scale with 4 sub-factors (sports-related, sleep quality, habitual sleep efficiency, sleep disturbance)

    Time frame: Pre-test and 1 month after the pre-test

  3. Pittsburgh Sleep Quality Index (PSQI)

    Pittsburgh Sleep Quality Index assesses various sleep-related factors, including sleep latency, sleep duration, sleep efficiency, and daytime sleepiness. It is a 19-item self-report questionnaire. Each item is scored from 0 to 3, and the total score ranges from 0 to 57. Higher scores indicate poorer sleep quality.

    Time frame: Pre-test and 1 month after the pre-test

  4. Cleveland Adolescent Sleepiness Questionnaire

    Cleveland Adolescent Sleepiness Questionnaire provides a valid and reliable subjective measure of daytime sleepiness in adolescents. This Questionnaire consists of 16 items that measure daytime sleepiness. Scores range from 16 to 80 on a 5-point Likert scale (never: 1; rarely: 2; sometimes: 3; usually: 4; almost every day: 5). Five of the statements are scored in the reverse direction. Daytime sleepiness is obtained by summing the scores of the 16 items, and the higher the score, the higher the daytime sleepiness.

    Time frame: Pre-test and 1 month after the pre-test

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2024 to primary completion in Jul 2024, 1 month.

Of 30 non-industry interventional studies with no phase under Sleep Hygiene, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 29. This study's 1 month is below that.

Counting every sponsor, half of 31 studies reached it within 8 months; a quarter within 3 and three quarters within 29.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 18, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
