摘　　要：主要采用观测法、数据统计法等研究方法,以全国10个省市34所学校的1 156名初中生为研究对象,运用计步器测试并计算出初中生在体育课堂上中到大强度运动(MVPA)的时间和步数之间的关系。结果发现:初中体育课中,71.81步/分钟是完成课堂时间50%的MVPA的分水岭;计步器测试的每分钟步数与MVPA的时间存在线性关系(r≥0.91,P≤0.01)。Based on observation, data statistics and pedometer test, with 1 156 junior middle school students from 34 schools in 10 cities/provinces across the country as the research subjects, this paper conducted a research into the relationship between the moderate and vigorous physical activity(MVPA) time and the number of their steps in physical education(PE) class. The results showed that 71.81 steps/min is the divide for completing 50% MVPA time in junior middle school PE class, and that there exists a linear relationship between the MVPA time and steps/time measured by the pedometer(r≥0.91,P≤0.01).
