Intrinsic motivation and exercise behavior

This study details the relationship between intrinsic motivation and exercise behavior in volunteer subjects (N=109) participating in an eight week aerobic fitness program. Prior to and following the program, the subjects completed measures of intrinsic motivation. Exercise leaders monitored subjects’ attendance at each class, serving as an indicant of exercise behavior. Subjects also indicated their perception of degree of success in the program and their intention to continue exercising post-program termination. Intrinsic motivation was found to be significantly associated with attendance and subjects’ confidence in their intentions to continue exercising post-program. Additionally, subjects’ perceptions of success experienced in the program were moderately related to post-program levels of intrinsic motivation. More successful subjects generally perceived themselves as being more competent, experiencing more enjoyment, and putting forth more effort. Results are discussed in terms of the role of intrinsic motivation as a predictor of exercise program participation.
