Timeline
Interventions
Participants in this group will receive a 16-week intervention of HIIT once weekly supervised by certified athletic coaches. Participants will perform four 4-minute intervals at 85%-95% peak heart rate with a 3-minute active recovery between each 4-minute interval. Participants will repeat the 25-minute HIIT bout three times with 30-60 minutes break in between each 25-minute HIIT bout. Health information provided to the usual care control group will be made available to the participants in the HIIT groups.
Participants in this group will receive a 16-week intervention of HIIT thrice weekly supervised by certified athletic coaches. Participants will perform four 4-minute intervals at 85%-95% peak heart rate with a 3-minute active recovery between each 4-minute interval. Health information provided to the usual care control group will be made available to the participants in the HIIT groups.
Participants in the usual care control group will receive health education delivered by research personnel. This program will consist of eight two-hour bi-weekly sessions covering major health issues relating to obesity including causes, prevalence, epidemiology, associated diseases, healthy diet, caloric restriction advice, physical activity, stress management, adequate sleep, as well as lifestyle counseling/consultation and goal-setting/record-keeping strategies for behavioral changes.
