Resting energy expenditure, substrate use, and video tapes.
OBJECTIVE
To investigate the effect of watching different types of video on energy expenditure.


METHODS
Randomised study assessing a "pleasant," an "amusing," an "exciting," and no video film clips.


METHODS
12 volunteers who did not know the purpose of the study.


METHODS
Changes in energy expenditure, substrate use, heart rate, and aural temperature during each film clip.


RESULTS
Energy expenditure was raised slightly (0.21 kJ/day) during the "exciting" film. Individual responses varied greatly.


CONCLUSIONS
Watching different types of video seems to have little effect on resting metabolic rate.
