Clinical Trial Summary

The overall goal of this project is to study the effects of exercise energy expenditure matched vigorous dynamic resistance training and aerobic training on cardiac fat, and its relationship to cardiac function and geometry using cardiac Magnetic Resonance Imaging.

Description:

Exercise-induced weight-loss is one of the most common strategies for reducing excess fat in overweight and obese individuals. Although vigorous intensity may be more favorable promoting positive cardiac adaptations compared to low-moderate intensity, evidence of the positive effects of different exercise modes needs to be explored to allow for realistic comparisons with other strategies. Research using cardiac Magnetic Resonance Imaging that compares the effects of different modes of exercise - matched by exercise energy expenditure - on epicardial adipose tissue and paracardial adipose tissue, and how these interventions modify cardiac function and geometry have not been previously explored in obesity.
