This study examined whether 20-m shuttle-run performance, sex, body mass index (BMI), age, height, and weight are associated with peak oxygen uptake (VO2peak) in youth with Down syndrome (DS; n = 53; 25 women, age 8-20 years) and whether these variables can be used to develop an equation to predict VO2peak. BMI, 20-m shuttle-run performance, and sex were significantly associated with VO2peak in youth with DS, whereas age, height, and weight were not. A regression model included only shuttle-run performance as a significant predictor of VO2peak; however, the developed prediction equation had low individual predictability. Therefore, 20-m shuttle-run performance alone does not provide valid prediction of VO2peak in youth with DS. Sex, BMI, age, height, and weight do not improve the prediction of VO2peak.
本研究调查了唐氏综合征（DS；n = 53；25名女性，年龄8 - 20岁）青少年的20米往返跑成绩、性别、体重指数（BMI）、年龄、身高和体重是否与峰值摄氧量（VO2peak）相关，以及这些变量是否可用于建立预测VO2peak的方程。BMI、20米往返跑成绩和性别与DS青少年的VO2peak显著相关，而年龄、身高和体重则不然。回归模型仅将往返跑成绩作为VO2peak的显著预测指标；然而，所建立的预测方程个体预测性较低。因此，仅20米往返跑成绩并不能有效预测DS青少年的VO2peak。性别、BMI、年龄、身高和体重并不能改善VO2peak的预测。
