The change pattern of step test index (STI) in female adolescents and its relationship with their maximal aerobic capacity were studied. Two hundred and thirteen girls aged 10 to 19 participated in the study. The physical and functional characteristics of the girls with higher STI scores were compared with those with lower ones. STI scores declined with age due to their increasing ratio of weight-to-height during puberty. The maximal aerobic working capacity was estimated by multiple regression analysis with the Quetelet Index (weight/height x 100) into the equation, and its accuracy of the prediction improved.
研究了女性青少年台阶试验指数（STI）的变化模式及其与最大有氧能力的关系。213名年龄在10至19岁的女孩参与了该研究。比较了STI得分较高的女孩与得分较低的女孩的身体和功能特征。由于青春期体重身高比增加，STI得分随年龄下降。通过将奎特莱指数（体重/身高×100）纳入方程进行多元回归分析来估计最大有氧工作能力，其预测准确性得到提高。
