EFFECTS OF BASE-LINE RESPONSES, IN-TASK FEELINGS, AND DURATION OF ACTIVITY ON EXERCISE-INDUCED FEELING STATES IN WOMEN

This study investigated the hypothesis that the effects of acute aerob ic exercise on feeling states may be influenced by the objective dose of activity, subjective responses during exercise, and preexisting lev els of feeling states. College-age women (N = 80) completed baseline m easures and were then randomly assigned to 1 of 4 conditions: attentio n control for 10 min, or exercise for 10 min, 25 min, or 40 min. Level s of exertion and affect were assessed during exercise, and posttestin g occurred 20 min following activity. Exercise enhanced revitalization in comparison with the control condition; however, this effect occurr ed only for participants scoring low to moderate on the pretest. In ad dition, in-task feeling states predicted postexercise revitalization e ven after we controlled for the treatment, the pretest, and the Pretes t x Treatment interaction.
