Beth Lewis, PhD, professor of Sport and Exercise Psychology in and director of the School of Kinesiology, and director of the Exercise and Mental Health Lab (EMHL), and Katie Schuver, PhD, post-doctoral fellow and member of the EMHL, along with Shira Dunsiger, PhD (Brown University), have published an article in PLOS ONE, “Evaluating the Feasibility and Efficacy of a Home-Based Combined High Intensity Interval and Moderate Intensity Training Program for Increasing Physical Activity among Low-Active Adults: A Randomized Pilot Trial.”

Results of Lewis and Schuver’s study indicated that a high intensity interval training (HIIT) intervention appears feasible based on retention, recruitment, adherence to counseling sessions, follow-up rates, and a consumer satisfaction survey. Participants reported more minutes of vigorous intensity physical activity at six weeks relative to the control group and reported higher levels of self-efficacy for and enjoyment of physical activity, as well as higher outcome expectations and more positive engagement with physical activity.
