To explore the differences and characteristics of cardiorespiratory fitness (CRF) among children and adolescents in regions with different latitudes in China.
A total of 9892 children and adolescents aged 7-22 years were selected from seven administrative regions in China by the stratified cluster random sampling method. CRF was measured by performance on the 20 m shuttle run test (20mSRT) and estimated maximal oxygen consumption (VO ). One-way ANOVA, one-way ANCOVA, and the Lambda Mu and Sigma methods were used to analyze the data.
Overall, the VO of children and adolescents at high latitudes was significantly lower than that of children at low and middle latitudes. The P , P , and P 20mSRT values for children and adolescents of most age groups in high latitudes were less than those in low and middle latitudes. The 20mSRT-Z and VO -Z scores among children and adolescents aged 7-22 in high latitudes were lower than those in middle and low latitudes after adjusting for age, per capita gross domestic product (GDP), and per capita disposable income.
In general, the CRF of children and adolescents at high latitudes was less than that at low and middle latitudes. Effective measures should be taken to improve CRF in children and adolescents at high latitudes.
探讨中国不同纬度地区儿童青少年心肺功能（CRF）的差异和特点。
采用分层整群随机抽样方法，选取中国 7 个行政区域的 9892 名 7-22 岁儿童青少年。CRF 通过 20 米穿梭跑测试（20mSRT）和估计的最大摄氧量（VO ）来测量。采用单因素方差分析、单因素协方差分析以及 Lambda Mu 和 Sigma 方法进行数据分析。
总体而言，高纬度地区儿童青少年的 VO 明显低于低纬度和中纬度地区。高纬度地区大多数年龄段儿童青少年的 20mSRT-P 、 P 、 P 20mSRT 值均小于低纬度和中纬度地区。调整年龄、人均国内生产总值（GDP）和人均可支配收入后，高纬度地区 7-22 岁儿童青少年的 20mSRT-Z 和 VO -Z 评分均低于中、低纬度地区。
总体而言，高纬度地区儿童青少年的 CRF 低于低纬度和中纬度地区。应采取有效措施提高高纬度地区儿童青少年的 CRF。
