NCT06849453

Brief Summary

Exploring the efficacy and acceptability of exercise snacks (ES) and sprint interval training (SIT) could provide time-efficient, low-barrier alternatives for individuals, especially those who, due to 'lack of time, environment, and equipment,' struggle to meet traditional physical activity recommendations. This research aims to investigate the effects of ES and SIT, of equal exercise volume, on overweight adults.
