Brief Summary
Physical inactivity is a major public health problem and a primary contributing factor to the obesity epidemic. While most Americans do not meet the physical activity (PA) guidelines (30 min/day, 5 day/wk), they do report watching several hours of TV each day, and frequently site "lack of time" as a barrier for engaging in PA. The Physical Activity and Leisure-time Study examines an approach convert sedentary TV watching into active TV watching time by having adults step in place during commercials (TV commercial stepping).

Study Arms (2)
30-min walk
ACTIVE COMPARATORInstructed to use "brisk" walking (at least 30 min/day in bouts of at least 10 min) at least 5 days/week. Participants were permitted to exercise in one long bout (30 min) or divide the exercise into multiple bouts as long as the bout length was 10 min or greater.
TV commercial stepping
EXPERIMENTALInstructed to stand and "briskly" step in place, or "briskly" walk continuously around the room/house for the duration of each commercial break during at least 90 min of TV programming on at least 5 days/week. Rather than exercising continuously for at least 10-minute bouts, participants performed multiple (\~9 or 10), short (\~3-5 min) bouts, conveniently incorporated into their daily TV viewing time.
Interventions
Participants were instructed to stand and "briskly" step in place, or "briskly" walk continuously around the room/house for the duration of each commercial break during at least 90 min of TV programming on at least 5 days/week. Both conditions will receive an ankle mounted Omron pedometer, so they were able to track their steps each day. Participants were not given instructions concerning diet modification or modifying TV viewing time during a 6 month behavioral physical activity intervention
