Mood State Changes of Women as a Function of Regular Aerobic Exercise

The present study examined mood states of aerobic exercisers before and after completing a 15-wk. program. The subjects (ages 18 to 36 yr.) were 86 women enrolled in activity classes at a large state school in the southeast. Subjects were initially classified according to previous exercise habits. Analysis indicated both groups of frequent and infrequent exercisers were similar in mood states. Participation in regular exercise did not significantly change or enhance the mood states from pre-treatment measures. Pretest measures of mood states provided poor prediction of posttest measures, indicating extreme variability in subjects' scores.
