Effects of consistent aerobic exercise on the psychological functioning of women

Effects of consistent aerobic exercise on depression, anxiety, and health locus of control for a group of nonclinical inactive women were investigated. Type A and Type H (hard-driving) behavioral styles were evaluated to determine whether these traits were related to exercise improvement. 26 women were randomly assigned to either an exercise group (n = 10) or exercise with cognitive strategy instructions (n = 16). All subjects increased distance run in 12-min. run test from pre- to posttest. Women improved in depression and trait anxiety. Depression was significantly correlated with body mass index at end of program. Posttest state-anxiety was significantly correlated with 6-wk. follow-up of exercise frequency. No significant difference in pre- and posttest health locus of control was found. Type H scores were significantly correlated with number of exercise sessions attended. Consistent aerobic exercise had a positive effect on psychological functioning, and some characteristics may affect exercise improvement.
