INTRODUCTION:: Modifying sedentary TV watching behaviors by stepping in place during commercials (TV commercial stepping) could increase physical activity and energy expenditure. PURPOSE:: To determine the energy cost of TV commercial stepping and to quantify the amount of activity (number of steps and minutes) performed during 1 hour of TV commercial stepping. METHODS:: In part 1, twenty-three adults (27.8±7.0 years) had their energy expenditure measured at rest, sitting, standing, stepping in place and walking at 3.0 mph on the treadmill. The second part of this study involved one hour of sedentary TV viewing and one hour of TV commercial stepping. Actual steps were counted with a hand-tally counter. RESULTS:: There were no differences (P=0.76) between the caloric requirements of reclining rest (79±16 kcal/hr), and sedentary TV viewing (81±19 kcal/hr). However, stepping in place (258±76 kcal/hr), walking at 3.0 mph on the treadmill (304±71 kcal/hr), and one hour of TV commercial stepping (148±40 kcal/hr), had a higher caloric requirement than either reclining rest or sedentary TV viewing (P<0.001). One hour of TV commercial stepping resulted in an average of 25.2 ±2.6 minutes of physical activity and 2111±253 steps. CONCLUSION:: Stepping in place during commercials can increase the energy cost and amount of activity performed during TV viewing. |
