Resistance Exercise and Sleep Quality by Chronotype

Официальное название

The Effects of Tailored Resistance Exercise on Sleep Quality in Relation to Chronotype

Обзор

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.

Подробное описание

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.

Null Hypothesis (H0): Moderate-intensity morning resistance exercise will have no differential effect on sleep quality, mood, or circadian alignment between participants with morning and evening chronotypes.

Alternative Hypothesis (H1):Moderate-intensity morning resistance exercise will have a differential effect on sleep quality, mood, or circadian alignment between participants with morning and evening chronotypes.
