Family Lifestyle Overweight Prevention Program-Physical Activity Only

Classes were designed to provide the opportunity to be physically activity at a moderate-vigorous level. Each station included exercise options to accommodate varying fitness levels and offer students choice. Heart rate monitors provided consistent biofeedback to students throughout the intervention. Participants were evaluated based on the number of minutes they spent each class between 60-80% of their maximal heart rate. Games were intermixed either as a station or as a break in the circuit (e.g. short game of tag half-way through the workout) to make physical activity enjoyable and engaging.

PE teachers were instructed to teach class as usual. Research staff were not involved in class activities or instruction. In this school district PE class as usual includes sports-based instruction in which students learn the rules to games and then practice playing.
