Abstract

The positive contribution of physical education (PE) to daily physical activity (PA) has been documented in past studies. However, little is known about the contribution of PE to inactive and unfit schoolchildren's PA. Therefore, the purpose of the present study was to examine the contribution of PE to the daily PA of schoolchildren, especially for inactive and unfit schoolchildren. Accelerometers were used to measure the PA of 111 boys (M = 13.6 0.8 years) across 7 days. Moderate-to-vigorous PA (MVPA) was measured during PE classes and on school days with and without PE classes. To measure the time that schoolchildren spent on MVPA, the accelerometer count (i.e., 2296 counts/minute) was used. Schoolchildren spent 22% of PE class time in MVPA. Times spent in MVPA were 12.9, 14.7 and 14.8 minutes higher on PE days than on days without PE for all, inactive, and unfit schoolchildren, respectively. Results showed that 40% percent and 24% of the schoolchildren met the recommended levels of PA on PE days and days without PE, respectively. It is concluded that, since PE classes increase daily engagement in MVPA, especially among inactive and unfit schoolchildren, PE classes should be conducted on all school days.

摘要

过去的研究已经证明了体育课（PE）对日常体育活动（PA）的积极贡献。然而，对于体育课对不活跃和身体不适的学生的 PA 的贡献知之甚少。因此，本研究的目的是检验体育课对学生日常 PA 的贡献，特别是对不活跃和身体不适的学生。使用加速度计测量了 111 名男孩（M=13.6±0.8 岁）在 7 天内的 PA。在有和没有体育课的情况下，在体育课和上学日测量了中等至剧烈强度的 PA（MVPA）。为了测量学生进行 MVPA 的时间，使用了加速度计计数（即 2296 计数/分钟）。学生在体育课上的时间有 22%用于 MVPA。对于所有学生、不活跃的学生和身体不适的学生，PE 日的 MVPA 时间分别比没有 PE 日多 12.9、14.7 和 14.8 分钟。结果表明，40%和 24%的学生在 PE 日和无 PE 日分别达到了推荐的 PA 水平。结论是，由于体育课增加了日常的 MVPA 参与度，尤其是对不活跃和身体不适的学生，因此所有上学日都应该开设体育课。
