Gender Specific Responses of Overweight and Obese Adults to Sprint Interval Training

Total of 80 eligible male (n=40) and female (n=40) young adults will be equally recruited using block randomization and chosen based on the inclusion and exclusion criteria. Before the study, all participants will be informed of the potential risks and benefits of the study. During the study period, participants will be instructed to avoid any form of physical activity besides the study protocol. Both groups will perform SIT protocol on a electromagnetically braked cycle ergometer three times per week for 6 weeks. Every session, participants start with a 5 minutes warm up at 50- 60% of heart rate maximum (HRmax) and follow by four 30-s all out bouts intersperse with 4 minutes of recovery (passive or no load cycling). For confirmation of all-out effort, participant are required to maintain his or her cycling cadence at least 60 rpm or above. Intervention will end with a 5 minutes cool down at 50- 60% of HRmax. Total duration for each session will be 28 minutes. If a participant misses fewer than three sessions per week non- consecutively, the sessions missed will be replace at the end of period. However, if participants misses three or more sessions, he or she will be excluded from the study. Outcome measures will be assessed at baseline and at end of 6 weeks of intervention.
