Effects of Combined High Intensity Interval Training and Resistance Training

Combined exercise group subjects will undergo weekly three sessions of both HIIT and resistance training for sixteen weeks. The HIIT session will involve four four-minute high-intensity intervals with an intensity of at 80-95% of the HRmax interspersed with two-minute active recovery intervals with intensity of 40% to 60% of the HRmax.

The control group subjects will be instructed not to change their usual daily physical activities routine and instructed to abstain from practicing any exercise regimens during the 12-week study period.
