AIMS
To determine if adolescents with and without Down syndrome (DS) accomplish the physical activity (PA) guidelines and to evaluate relationships between PA and cardiorespiratory variables.
METHODS
42 adolescents (27 with DS) participated in this study. PA was measured using accelerometers. Walking-graded treadmill protocol with a breath-by-breath gas analyzer was employed to assess cardiorespiratory fitness.
RESULTS
Adolescents with DS spent less time in sedentary PA, moderate PA (MPA), vigorous PA (VPA) and moderate to vigorous PA (MVPA) than those without DS. VO2peak was correlated with total minutes spent in light PA, MPA, VPA and MVPA in the control group (from r = 0.55 to r = 0.61, p < 0.05) and with MPA and MVPA in the DS group (from r = 0.38 to r = 0.41, p < 0.05).
CONCLUSION
Nor DS neither control groups achieved at least 60 minutes of MPA daily. Engaging more time in MPA was associated with greater cardiorespiratory fitness in adolescents with DS.
目的
确定患有和未患有唐氏综合征（DS）的青少年是否达到身体活动（PA）指南要求，并评估身体活动与心肺变量之间的关系。
方法
42名青少年（27名患有DS）参与了本研究。使用加速度计测量身体活动。采用带有逐次呼吸气体分析仪的步行分级跑步机方案评估心肺适能。
结果
与未患DS的青少年相比，患DS的青少年在久坐行为、中等强度身体活动（MPA）、剧烈身体活动（VPA）和中等至剧烈身体活动（MVPA）上花费的时间更少。对照组中，峰值摄氧量（VO2peak）与轻度身体活动、MPA、VPA和MVPA的总时长相关（r值从0.55至0.61，p<0.05），在DS组中与MPA和MVPA相关（r值从0.38至0.41，p<0.05）。
结论
DS组和对照组均未达到每日至少60分钟的MPA。在患DS的青少年中，增加MPA的时长与更好的心肺适能相关。
