Abstract:
OBJECTIVE:To investigate the effect of watching different types of video on energy expenditure. DESIGN:Randomised study assessing a "pleasant," an "amusing," an "exciting," and no video film clips. SUBJECTS:12 volunteers who did not know the purpose of the study. MAIN OUTCOME MEASURES: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. CONCLUSION:Watching different types of video seems to have little effect on resting metabolic rate.
