An interventional study of Aerobic exercise Training and Sleep hygiene education in Healthy Individuals, sponsored by Cairo University. Not yet recruiting at 1 site in Egypt. Open to participants aged 18 Years to 25 Years. Per ClinicalTrials.gov, last updated 2026-11-02.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
The purpose of this study is to investigate the impact of moderate-intensity aerobic treadmill exercise on sleep quality and postural control interplay among university students with poor sleep quality. Sleep disturbances are highly prevalent in university populations and can lead to impaired balance and increased postural sway. While aerobic exercise is known to enhance sleep quality, its combined effect on objective postural control measures remains understudied in this group.
Sixty-six university students (aged 18-25 years) with self-reported poor sleep quality will be randomly allocated into two equal groups: an intervention group (aerobic exercise training plus sleep hygiene education) and a control group (sleep hygiene education only). Primary and secondary outcomes include sleep quality, objective balance indices, dynamic balance, insomnia severity, anxiety levels, and mindfulness assessed pre- and post-intervention at 6 weeks.
This study investigates the reciprocal relationship and interplay between sleep quality and postural control among young adults, evaluating how a structured moderate-intensity aerobic exercise intervention impacts both primary outcomes. Participants meeting the eligibility criteria are randomized into two parallel groups: an experimental group receiving a 6-week treadmill exercise intervention combined with sleep hygiene education, and a control group receiving sleep hygiene education alone.
The exercise program consists of treadmill walking/jogging performed 3 sessions per week for 6 consecutive weeks. Each session lasts 40 minutes and comprises a 5-minute low-speed warm-up, 30 minutes of continuous moderate-intensity exercise calibrated to 60-75% of maximum heart rate (HRmax), and a 5-minute cool-down. Exercise heart rates are continuously monitored to ensure adherence to target intensity ranges. The standardized sleep hygiene education includes advice on regular sleep schedules, optimal sleep environment, and restriction of stimulant intake before sleep. Baseline and post-intervention evaluations assess sleep architecture, postural stability metrics, day-time sleepiness, anxiety levels, and sleepiness-related mindfulness to determine the potential therapeutic synergistic effects of aerobic exercise on the sleep-balance relationship.

Behavioral: Sleep hygiene education
Aerobic exercise training on treadmill (3 sessions/week for 6 weeks) combined with sleep hygiene education
Behavioral: Aerobic exercise Training · Behavioral: Sleep hygiene education
Participants in intervention group will undertake a 6-week moderate-intensity aerobic exercise program performed on a motorized treadmill for 3 sessions per week. Each session lasts 40 minutes, consisting of a 5-minute warm-up (low-speed walking), 30 minutes of continuous walking/jogging at 60-75% of maximum heart rate (HRmax), and a 5-minute cool-down.
A standardized sleep hygiene education program consisting of a 15-30 minute instructional session (verbal explanation and printed brochure) covering healthy sleep practices and environment adjustments. Participants will maintain their usual daily activities for 6 weeks with weekly compliance monitoring.
Sleep Quality (PSQI Global Score)
Pittsburgh Sleep Quality Index (PSQI) Global Score (scale range: 0 to 21, where lower scores indicate better sleep quality).
Time frame: Baseline (Pre-intervention) and Post-intervention (Week 6)
Overall Stability Index (OSI)
Overall Stability Index (OSI) measured using the Biodex Balance System (scale range: 0 to higher values, where higher scores indicate greater postural instability and worse outcome)
Time frame: Baseline (pre-intervention) and post-intervention (at 6 weeks)
Insomnia Severity Index (ISI)
Assesses the nature, severity, and impact of insomnia symptoms over the past two weeks using a 7-item self-report questionnaire, with total scores ranging from 0 to 28 (where higher scores indicate greater insomnia severity and worse outcome).
Time frame: Baseline (pre-intervention) and post-intervention (at 6 weeks)
Generalized Anxiety Symptoms (GAD-7)
Measures the severity of generalized anxiety symptoms over the past two weeks using a 7-item scale, with total scores ranging from 0 to 21 (where higher scores indicate greater anxiety severity and worse outcome).

Start is estimated for Oct 2026; primary completion for Dec 2026, 2 months later.
Of 1,207 non-industry interventional studies with no phase under Sleep Initiation and Maintenance Disorders, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 35. This study's planned 2 months is below that.
Counting every sponsor, half of 1,285 studies reached it within 15 months; a quarter within 6 and three quarters within 34.
