Abstract
There is considerable support for shifting the focus away from moderate-tovigorous
exercise toward increasing low-to-moderate intensity physical activity.
Experimental work has shown !bat low-intensity incidental activity rather than
moderate- or vigorous-intensity activity distinguishes the lean from !be obese
(Levine et a/., 2008a,b). Convincing evidence in animals verifies this
proposition, showing benefit in lipid metabolic pathways from increasing lowintensity
activity, as opposed to vigorous-intensity exercise (Hamilton et a/.,
2007). Serum cholesterol and triglyceride have been found to decrease after
only I week of increased moderate intensity physical activity, combined with
the consumption of a low fat and high fibre diet (Schmidt eta/., 201 1). With the
current interest in the use of low-to-moderate intensity activity-enhanced video
games as an alternative form of physical activity, it is necessary to establish if
similar metabolic benefit is conferred by Ibis lower intensity activity. The
purpose of this study was to determine whether a short-term low-intensity
interactive video-game treadmill walking programme, without dietary
manipulation, was effective in altering !be lipid profile of obese adolescents.
