Abstract: | We sought to determine the performance and anthropometric correlates of physical self-concept and self-esteem and to observe whether long-term resistance training would alter these variables in postmenopausal women. Forty-four nonsmoking, community-dwelling, Caucasian women aged 50-75 years participated in the study. Half of the subjects participated in a 9-month regimen of weight-bearing exercises performed 3 times per week which emphasized lower body muscle strength and power development. At baseline, total body fat was negatively associated with physical self-concept and perception of physical appearance but not with self-esteem. Perception of physical appearance improved in both exercisers and controls after the 9-month trial but was most noticeable in exercisers who had low self-esteem at baseline. The only predictor of improvement in perception of physical appearance was a decrease in lower body fat mass. Minimal or nonsignificant change in psychological measures associated with the training may be due to high initial values. |
