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.
在11名9至11岁的儿童参与为期8周的精准跳绳引导训练计划之前和之后，对他们进行了两种自我概念测量。尽管这些儿童一开始作为一个群体表现出较高的自我概念，但在跳绳训练之后，这一测量指标出现了显著改善。这种心理变化被注意到，而身体成分和心血管健康的生理指标却没有改变。
