Abstract

Watching television or listening to music while exercising can serve as motivating factors, making it more pleasant to exercise for some people. However, it is unknown whether these stimuli influence food intake and/or physical activity energy expenditure (PAEE) for the remainder of the day, potentially impacting energy balance and weight control. We examined the effects of watching television or listening to music while exercising on post-exercise energy intake and expenditure. Our study was a randomized crossover design, in which 24 male adolescents (mean age: 14.9 ± 1.1 years) completed three 30-min experimental conditions consisting of walking/jogging on a treadmill at 60% of heart rate reserve while (1) watching television; (2) listening to music; or (3) exercising with no other stimulus (control). An ad libitum lunch was offered immediately after the experimental conditions, and a dietary record was used to assess food intake for the remainder of the day. An Actical accelerometer was used to estimate PAEE until bedtime. The primary outcome measure was post-exercise energy intake and expenditure (kJ). We found that exercising while watching television or listening to music did not significantly affect post-exercise energy intake or energy expenditure. Exercising on a treadmill was found to be significantly more enjoyable while watching television than with no stimulus present. Ratings of perceived exertion were not significantly different between conditions. Overall, our results suggest that watching television or listening to music while exercising does not impact post-exercise energy intake or expenditure in male adolescents, which may have positive implications for adolescents who may need additional motivation to participate in physical activity.
