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.
