Abstract:
There is a common belief that, when allowed to select their exercise intensity, mostpeople choose levels too low to accrue substantial benefits. Thus, one of the presumed functionsof exercise practitioners is to "push" participants. A previous study showed that, if theimposed intensity exceeds the self-selected by even 10%, this suffices to reduce pleasure.Here, we isolated the effect of autonomy loss by having participants (a) exercise at a selfselectedintensity and (b) exercise at an intensity set by the experimenter, which was identicalto the self-selected. This reduced perception of autonomy and choice, and also attenuatedincreases in energy and levels of interest/enjoyment after the controlled condition.These effects could not be accounted for by differences in intensity, perceived competence,or self-efficacy. Thus, consistent with self-determination theory, loss of perceived autonomyin setting one's level of exercise intensity can negatively impact affect, with potentially negativeimplications for adherence
