Two pilot studies were conducted to examine whether 6th grade students can achieve moderate to vigorous physical activity (MVPA) from 1) activity-based physical education (AB-PE) with 585 participants and 2) a curricular-based (CB-PE) program with 1,544 participants and randomly sampled heart rates during lessons. AB-PE participants spent between 54-66% with a heart rate >140 bpm. CB-PE participants spent between 49-58% with a heart rate >140 bpm. Girls' mean heart rate was 3.7 bpm lower than the boys. PE can be readily modified so that students spend more than 50% of time in MVPA.
开展了两项试点研究,以检验六年级学生能否通过以下两种方式实现中度至剧烈身体活动(MVPA):一是有585名参与者的基于活动的体育教育(AB-PE),二是有1544名参与者的基于课程的(CB-PE)项目,并在课程期间随机抽取心率。AB-PE参与者心率>140次/分钟的时间占54%-66%。CB-PE参与者心率>140次/分钟的时间占49%-58%。女孩的平均心率比男孩低3.7次/分钟。体育教育可以很容易地进行调整,以便学生在MVPA中花费超过50%的时间。
