BACKGROUND
The purpose of this study was to examine whether there are differences in physical activity (PA) during specific periods of the day among active and less-active girls.
METHODS
The sample comprised 54 girls age 10 to 15 years. PA was assessed by accelerometry. Girls were grouped as less active, active, and highly active.
RESULTS
Total minutes of moderate-to-vigorous physical activity (MVPA) was significantly higher in more-active girls than in their less-active peers (113 and 72 min/d, respectively). The most-active groups were significantly more engaged in MVPA during the outside-of-school period than were less-active girls. Highly active girls spent a significantly higher amount of their MVPA time outside of school than did the less-active group, which spent a significantly higher proportion of MVPA time during late afternoon.
CONCLUSION
Outside-of-school PA is a key point for MVPA engagement. Particularly for the less-active girls, however, schools might provide additional PA.
背景
本研究旨在探讨活跃程度不同的女孩在一天中的特定时间段内的身体活动（PA）是否存在差异。
方法
样本包括54名10至15岁的女孩。通过加速度计评估身体活动。女孩们被分为活动较少、活动较多和高度活跃三组。
结果
活动较多的女孩中度至剧烈身体活动（MVPA）的总分钟数显著高于活动较少的同龄人（分别为每天113分钟和72分钟）。最活跃的组在课外时间比活动较少的女孩更积极参与MVPA。高度活跃的女孩在校外度过的MVPA时间显著多于活动较少的组，而活动较少的组在下午晚些时候度过的MVPA时间比例显著更高。
结论
课外身体活动是参与MVPA的关键点。然而，特别是对于活动较少的女孩，学校可能需要提供额外的身体活动。
