Workout on Wheels Internet Intervention (WOWii)

"Participants will self-monitor their exercise on the WOWii website, which has a page to record the type, duration, and intensity of daily exercise bouts.~Two devices will track participants' exercise, a Polar heart rate monitor (RS300X, Polar®), which will provide data on the day, duration, and intensity (average and maximum) of aerobic activity and an ActiGraph accelerometer (model GT3X), which detects movement in three planes to indicate frequency and intensity of movement throughout the day. Experimental participants will be provided a Polar heart rate monitor to wear during each exercise bout for the entire length of the 6-month study, and exercise data will be collected weekly.~Physiological outcomes on fitness will be assessed by measuring weight and aerobic capacity in a Cardiopulmonary Lab by a doctoral-trained physical therapist.~Participants will complete surveys to report on their exercise self-efficacy and perceived barriers."
