          Abstract

          Objective To understand physical activity status and its relation with cardiopulmonary endurance among Chinese children and adolescents, so as to provide reference for cardiopulmonary endurance improvement and intervention of Chinese children and adolescents.

          Methods During September to November 2018, a stratified cluster sampling method was used to select 4 269 children and adolescents aged 7–18 years in six major regions of China, 20 m shuttle run test and physical activity were assessed.

          Results Average duration for daily low-intensity physical activity among boys was (31.49±30.01) min, for moderate-to-vigorous physical activity (68.37±46.50) min. Average duration for low-intensity physical activity among girls was (34.02±31.58) min, for moderate-to-vigorous physical activity was (63.02±44.91) min. The number of 20 m shuttle run test for boys reached (36.17±21.94) times, and the maximal oxygen uptake per minute was (44.51±5.05) mL/kg; the number of 20 m shuttle run test for girls reached (26.59±12.56) times, and the maximal oxygen uptake per minute was (41.99±5.29) mL/kg. There were statistically significant differences in the number of 20 m shuttle run test and maximal oxygen uptake across age groups in boys ( F=589.37, 152.79, P<0.01), as well as that in girls ( F=305.21, 1 032.46, P<0.01). The proportion of boys and girls who met moderate-to-vigorous physical activity standard was 49.24% and 42.92%, respectively. Linear regression analysis showed that there was a significant positive correlation between the duration of moderate-to-vigorous physical activity and maximal oxygen uptake (β=0.11, P<0.01).

          Conclusion There is a significant correlation between moderate-to-vigorous physical activity with cardiorespiratory endurance among Chinese children and adolescents. Higher level of moderate-to-vigorous physical activity is important to help improve cardiopulmonary endurance among children and adolescents.

          Abstract

          【摘要】 目的 了解中国儿童青少年体力活动状况及其与心肺耐力的关系, 为提髙中国儿童青少年心肺耐力水平提供参 考和借鉴。 方法 在 2018 年 9一11 月采用分层整群抽样的方法, 在中国六大行政区抽取 7~18 岁的 4 269 名儿童青少年 进行基本情况、20 m 往返跑测试及体力活动状况的测试和调査。 结果 男生每天低强度体力活动时间为 (31.49±30.01) min, 中髙强度体力活动时间为 (68.37±46.50) min; 女生低强度体力活动时间为 (34.02±31.58) min, 中髙强度体力活动时间 为 (63.02±44.91) min。7~18 岁男生 20 m 往返跑次数为 (36.17±21.94) 次, 每分钟最大摄氧量为 (44.51±5.05) mL/kg; 女生 20 m 往返跑次数为 (26.59±12.56) 次, 每分钟最大摄氧量为 (41.99±5.29) mL/kg。男生各年龄段 20 m 往返跑次数和最大摄 氧量的比较差异有统计学意义 ( F 值分别为 589.37, 152.79, P 值均<0.01); 女生间差异也均有统计学意义 ( F 值分别为 305.21, 1 032.46, P 值均<0.01)。中髙强度体力活动时间男生达标者比例为 49.24%, 女生为 42.92%。线性回归分析显示, 中髙强度体力活动时间与最大摄氧量呈正相关 (β=0.11, P<0.01)。 结论 中国儿童青少年中髙强度体力活动时间与心肺 耐力呈现相关性, 可通过提髙儿童青少年的中髙强度体力活动以达到提髙心肺耐力的目的。
