Self-concept responses of children to participation in an eight-week precision jump-rope program.

Two measures of self-concept were administered to 11 children, aged from 9 to 11 yr., before and after 8 wk. of participation in a guided exercise program of precision rope jumping. Despite the fact that the children evidenced as a group high self-concept at the outset, a significant improvement on this measure appeared after the jump-rope regimen. This psychological change was noted while there was no alteration in the physiological indices of body composition and cardiovascular fitness.
