OBJECTIVE
Cardiorespiratory fitness (CRF) reference data for Tibetan (Zang ethnicity) children and adolescents at high altitudes in Tibet of China are lacking. The present study aimed to develop sex- and age-specific 20mSRT norms for Chinese Tibetan children and adolescents at high altitudes.
METHOD
A total of 4667 participants from Lhasa (3650 m), Nagqu (4500 m), and Amdo (4700 m) were selected by a stratified random cluster sampling method in two stages. The 20 m SRT test was used to estimate cardiorespiratory fitness. The 20 m SRT norms were developed by the lambda, mu, and sigma method (LMS).
RESULTS
The 20 m SRT laps, completed stages/minutes, and the speed at the last complete stage of Chinese Tibetan children and adolescents aged 7-18 years increased with age.
CONCLUSION
Given the importance of CRF for children and adolescents' health, the government should strengthen the monitoring of the CRF of Tibetan children and adolescents in high-altitude areas, strengthen physical education curriculum reform, and increase the level of physical activity in order to improve the level of CRF in children and adolescents.
目的
中国西藏高海拔地区藏族（藏人）儿童和青少年的心肺适能（CRF）参考数据缺乏。本研究旨在为高海拔地区的中国藏族儿童和青少年制定性别和年龄特异性的 20mSRT 标准。
方法
采用两阶段分层随机整群抽样方法，从拉萨（3650 米）、那曲（4500 米）和安多（4700 米）选取了 4667 名参与者。使用 20mSRT 测试来估计心肺适能。20mSRT 标准采用 lambda、mu 和 sigma 方法（LMS）制定。
结果
7-18 岁中国藏族儿童和青少年的 20mSRT 圈数、完成阶段/分钟数以及最后一个完整阶段的速度随年龄增长而增加。
结论
鉴于 CRF 对儿童和青少年健康的重要性，政府应加强对高海拔地区藏族儿童和青少年 CRF 的监测，加强体育课程改革，增加儿童和青少年的身体活动水平，以提高 CRF 水平。
