About

The purpose of this study is to research the effects of exercising at high intensities for short periods of time on exercise tolerance and motivation.

Full description

The proposed research will investigate whether adding a treatment component that focuses on positive outcome expectations of a high-intensity interval training (HIIT) intervention produces greater improvements in psychological and physiological study outcomes. This project will yield empirical evidence that will inform how to help Americans meet physical activity guidelines; how to develop exercise programs that are more likely to promote exercise as a habit; and maintenance of health and a healthy body weight.
