Watching television or listening to music during exercise has been shown to increase
the enjoyment of the activity and decrease fatigue for some people. However, it is
currently unknown how these stimuli during an exercise session play a role in postexercise
energy intake and/or physical activity energy expenditure (PAEE). The purpose
of this thesis was to examine the effects of watching television or listening to music
while exercising on post-exercise energy intake and expenditure in male adolescents.
The study consisted of a randomized crossover design involving 24 male adolescents
aged 12 to 17 years. The participants completed three experimental sessions that
included walking/jogging on a treadmill at 60% of their heart rate reserve for 30 minutes
while watching television, listening to music, or exercising with no other stimulus
(control). Following the exercise sessions participants were given an ad libitum lunch
and were asked to record their food intake for the remainder of the day. An Actical
accelerometer was used to assess PAEE until bedtime. The primary outcome measure
was post-exercise energy intake and energy expenditure. Results showed that
exercising while watching television or listening to music did not significantly affect postexercise
energy intake or energy expenditure. Walking/jogging on a treadmill was found
to be more enjoyable while watching television than with no stimulus present (p=0.03).
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 exercise.
