简要总结
This study examines whether doing moderate resistance exercises in the morning can improve sleep quality and well-being in young adults. Participants with different daily activity patterns (morning or evening types) will take part in an 8-week online exercise program. The study will compare how exercise affects sleep, mood, and daily rhythm across these groups.
详细描述
Disturbed sleep is a widespread issue that affects health, mood, and daily function. Chronotype-the natural tendency to be active earlier or later in the day-may influence how people respond to exercise as a tool for improving sleep.
This trial investigates the effects of an 8-week, moderate-intensity resistance exercise program performed in the morning, delivered through telerehabilitation.
Participants include healthy young adults with self-identified morning or evening chronotypes. The study will measure changes in sleep quality, psychological well-being, alignment of daily rhythms, and will explore whether men and women respond differently to the program..
By comparing outcomes between chronotypes, this research aims to clarify whether exercise benefits are shaped by biological preference for morning or evening activity, or whether improvements occur regardless of chronotype.
The central question is whether improvements occur equally across chronotypes, or if biological preference shapes the response to exercise.

盲法说明
Participants will not be masked due to the nature of the supervised exercise sessions and chronotype classification. Outcome measures rely on self-reported questionnaires and standardized assessments, making blinding of participants impractical.

结局指标
主要结局
Change in Sleep Quality Assessed by Pittsburgh Sleep Quality Index (PSQI)
时间窗: Baseline, Week 4, and Week 8; primary comparison is change from baseline to Week 8
Sleep quality will be measured using the Pittsburgh Sleep Quality Index (PSQI), a validated 19-item self-report questionnaire that evaluates sleep patterns over the past month. The PSQI generates seven component scores (subjective sleep quality, latency, duration, efficiency, disturbances, use of medication, daytime dysfunction), which are summed into a global score ranging from 0 to 21, with higher scores indicating poorer sleep quality. Assessments will be conducted at baseline (week 0), midpoint (week 4), and end of study (week 8). The primary endpoint is the change in global PSQI score from baseline to week 8, comparing differences between morning and evening chronotype groups following the resistance exercise program.
