Recreational Badminton, Sleep and Melatonin
A study testing Recreational Badminton in people with Sedentary Behavior, run by Inonu University at 1 site in Turkey (Türkiye).
Trial summary
Poor sleep quality is increasingly prevalent among physically inactive young adults and is associated with adverse physical and mental health outcomes. Regular physical activity may improve sleep quality and circadian regulation, although evidence regarding recreational sports remains limited. Read more about this study

About this study
Official title: Effect of Recreational Badminton on Sleep Quality and Salivary Melatonin in Physically Inactive Young Adults: A Randomized Controlled Trial
Poor sleep quality is increasingly prevalent among physically inactive young adults and is associated with adverse physical and mental health outcomes. Regular physical activity may improve sleep quality and circadian regulation, although evidence regarding recreational sports remains limited. This randomized controlled trial investigated the effects of a 4 week supervised recreational badminton program on sleep quality and salivary melatonin concentrations in physically inactive young adults. Participants were randomly assigned to either a badminton intervention group or a control group. Sleep quality and salivary melatonin levels were assessed before and after the intervention.
Read the detailed description
This randomized controlled trial was designed to investigate whether a 4 week supervised recreational badminton program could improve sleep quality and influence salivary melatonin concentrations in physically inactive young adults. Poor sleep quality is increasingly recognized as an important health concern among young adults and may negatively affect physical functioning, psychological well-being, cognitive performance, and daily functioning. Although regular physical activity has been consistently associated with better sleep outcomes, evidence regarding the effects of recreational sports such as badminton remains limited. Badminton is a dynamic, enjoyable, and relatively accessible sport that combines aerobic and anaerobic activity, coordination, agility and intermittent high intensity movements, which may provide both physiological and psychological benefits. In this study, physically inactive young adults were randomly allocated to either a supervised badminton intervention group or a control group. Participants in the intervention group participated in a structured 4 week recreational badminton program, whereas participants in the control group maintained their usual daily routines. Sleep quality and salivary melatonin concentrations were evaluated before and after the intervention to assess both subjective sleep-related outcomes and a physiological marker associated with sleep wake regulation and circadian rhythms.

Recreational BadmintonBehavioural
It is well established that regular exercise has positive effects on both physiological and psychological health. Existing research indicates that regular physical activity reduces sleep latency, increases sleep duration, and improves overall sleep quality. Furthermore, exercise can contribute to the regulation of circadian rhythms by influencing the secretion of the hormone melatonin. Consequently, experts recommend exercise programs to individuals to improve their health status, sleep, and quality of life. It has been noted that exercise facilitates falling asleep, promotes deeper sleep, and enhances how individuals feel upon waking in the morning. However, studies directly comparing melatonin secretion and sleep quality between individuals who engage in recreational exercise and those who do not remain limited. This study aims to conduct a comparative analysis between these two groups to more clearly elucidate the effects of recreational exercise on sleep. The findings are expected

| Study group | Role | What they receive |
|---|---|---|
| The group that exercises | Experimental | The study is planned to last four weeks, during which participants will undergo various assessment methods. Healthy university students aged 18-30 will be included in the study. Individuals who exercise will be defined as those engaging in at least 150 minutes of moderate-intensity recreational badminton activity per week, while sedentary individuals will be defined as those exercising for less than 30 minutes per week. The G*Power 3.1 program was used to determine the sample size. Based on a study examining changes in sleep quality following different exercise interventions (Jurado-Fasoli et al., 2020), the effect size was calculated as 0.40 (eta-squared = 0.138), with a statistical power of 0.95 and a significance level of 0.05. With a design involving two groups and three measurement points, it was determined that a minimum of 9 participants per group-totaling 18 participants-would be sufficient.

What is being measured
The primary outcome is the main question the study is designed to answer.
Salivary Melatonin Measurements
Melatonin levels will be determined using saliva samples collected from participants at three different times of the day (8:00 AM, 8:00 PM, and 12:00 AM). Analyses will be performed using the Enzyme-Linked Immunosorbent Assay (ELISA) method.
Measured: 3 MONTHS
