RELATIONSHIP BETWEEN SELF-EFFICACY, EXERCISE INTENSITY, AND FEELING STATES IN A SEDENTARY POPULATION DURING AND FOLLOWING AN ACUTE BOUT OF EXERCISE

This study examined the relationship between self-efficacy, exercise i ntensity, and feeling states in a sedentary population during and foll owing an acute bout of exercise. Sixty sedentary participants were ran domly assigned to either a moderate-intensity (45-50% age predicted He art Rate Reserve; HRR), high-intensity exercise (70-75% HRR) group, or a no-exercise attention control group. Participants in both exercise groups experienced changes in feeling states across the course of the exercise bout. The moderate-intensity group reported more positive and fewer negative feeling states both during and after exercise than the high-intensity group. Participants in both exercise conditions were s ignificantly more positively engaged than the attention-control group postexercise. Consistent with social cognitive theory (Bandura, 1986, 1997), the reciprocal determined relationship between self-efficacy an d feeling states was found to be strongest in the high intensity exerc ise condition.
