About

The overall goal of this project is to the study the effects of an aerobic interval training program on cardiac fat, and its relationship to cardiac function using cardiac Magnetic Resonance Imaging.

Aerobic interval

Experimental group

Description:

Aerobic interval will consist of a supervised aerobic interval training sessions 3 times/week. Duration will range between 45-50 min/session depending on the exercise energy expenditure (target expenditure \~450-500kcal/session). Each interval will have a total duration of 5 min, and it will be divided into 2 periods. The first period will consist of 3 minutes of high-intensity activity at 70-85% of predicted HRmax, and for the second period the intensity will be reduced to 60-65% of predicted HRmax for 2 minutes. The training sessions will be carried out outdoors at the trails located on campus. The activity will consist of walking and/or light jogging. The speed/incline will be changed depending on the participants' heart rate and perception using the Borg's rating of perceived exertion (RPE) as needed. The RPE for the first period range will be 13-17 (15-17 at the end of the period) and 10-12 for the second period.
