The Effects of Exercise Snacks on Endothelial Function and Body Composition in Overweight Individuals
Sponsor: Weifang Medical University
Summary
This randomized controlled trial investigates the effects of two types of stair-climbing exercise snacks versus moderate-intensity continuous training on vascular health, body composition, and blood lipids in overweight or obese adults. Participants will be assigned to one of four groups for 6-8 weeks. The control group receives no exercise intervention. Primary outcomes include endothelial function (ultrasound), body composition (InBody), and lipid profile (blood test).

Conditions
Interventions
Short-term stair climbing exercise snack group
Adopt a fragmented approach, climbing stairs 4-5 times a day, each time climbing 5 floors (approximately 1 minute per session), with at least 1 hour of interval between each session, and spread throughout the daily activity periods. Exercise 3-5 days per week for a total of 6-8 weeks.
Long-duration stair climbing exercise snack group
On the basis of climbing stairs 4 to 5 times a day, increase the single exercise volume: complete 2 or 3 sets of climbing 5 floors of stairs each time (that is, the total number of floors climbed each time is 10 or 15), with no more than 1 minute of rest between sets. The intervals between each exercise should be at least 1 hour. Exercise 3 to 5 days a week, for a total of 6 to 8 weeks of intervention.
Moderate-intensity continuous exercise(MICT)
Exercise 3 to 5 days per week for a total of 6 to 8 weeks. Perform 30 minutes of moderate-intensity running training every day.
