Summary

This randomized controlled study examined whether exercise snacks could improve skeletal muscle strength and related physical fitness in sedentary female university students. Eligible participants were sedentary women aged 18 to 25 years who were randomly assigned to an exercise snacks group, a regular exercise group, or a control group. The intervention lasted 8 weeks. The exercise snacks group accumulated short bouts of exercise across the day, while the regular exercise group completed more concentrated exercise sessions three times per week. The control group maintained their usual lifestyle. Muscle strength and related physical fitness were assessed before and after the intervention. The study aimed to evaluate the effectiveness, feasibility, and safety of exercise snacks in a university setting.

Interventions

BEHAVIORAL

Exercise Snacks

Participants performed an 8-week exercise snacks program consisting of short bouts of physical activity distributed across the day. The program was performed 7 days per week, with approximately 75 minutes of exercise per week. Participants completed approximately 11 minutes of short exercise on weekdays and 10 minutes on weekends. Exercise guidance, reminders, adherence monitoring, and ratings of perceived exertion were provided through the Tizhiyun mobile application.

BEHAVIORAL

Regular Exercise

Participants performed an 8-week regular exercise program. Exercise sessions were completed three times per week on Monday, Wednesday, and Friday, with each session lasting approximately 25 minutes. Exercise guidance, reminders, adherence monitoring, and ratings of perceived exertion were provided through the Tizhiyun mobile application.
