Heterogeneity of Incentives for Physical Activity and Self-Efficacy in Highly Active and Moderately Active Women Exercisers

The purpose of this investigation was to examine whether persons exercising 2 times per week or less versus 3 times per week or more, with intentions to maintain current level of activity form a homogenous group in terms of motivational features. A group of 86 women recruited from local fitness clubs reported on their exercise incentives, self-efficacy, exercise behavior, and exercise intentions. A discriminant function analysis revealed that self-efficacy and incentives for stress reduction and mental health discriminated highly active from moderately active women. The implications of these findings are discussed in terms of stage theory and research in exercise adherence.
