BACKGROUND
Although previous studies have demonstrated that children with high levels of fundamental movement skill competency are more active throughout the day, little is known regarding children's fundamental movement skill competency and their physical activity during key time periods of the school day (i.e., lunchtime, recess and after-school). The purpose of this study was to examine the associations between fundamental movement skill competency and objectively measured moderate-to-vigorous physical activity (MVPA) throughout the school day among children attending primary schools in low-income communities.
METHODS
Eight primary schools from low-income communities and 460 children (8.5 ± 0.6 years, 54% girls) were involved in the study. Children's fundamental movement skill competency (TGMD-2; 6 locomotor and 6 object-control skills), objectively measured physical activity (ActiGraph GT3X and GT3X + accelerometers), height, weight and demographics were assessed. Multilevel linear mixed models were used to assess the cross-sectional associations between fundamental movement skills and MVPA.
RESULTS
After adjusting for age, sex, BMI and socio-economic status, locomotor skill competency was positively associated with total (P=0.002, r=0.15) and after-school (P=0.014, r=0.13) MVPA. Object-control skill competency was positively associated with total (P<0.001, r=0.20), lunchtime (P=0.03, r=0.10), recess (P=0.006, r=0.11) and after-school (P=0.022, r=0.13) MVPA.
CONCLUSIONS
Object-control skill competency appears to be a better predictor of children's MVPA during school-based physical activity opportunities than locomotor skill competency. Improving fundamental movement skill competency, particularly object-control skills, may contribute to increased levels of children's MVPA throughout the day.

背景
尽管先前的研究表明，基本运动技能水平较高的儿童在一天中更活跃，但对于儿童在学校日的关键时间段（即午餐时间、课间休息和课后）的基本运动技能水平及其身体活动知之甚少。本研究旨在探讨低收入社区小学儿童基本运动技能水平与全天中度至剧烈体力活动（MVPA）之间的关联。
方法
该研究涉及 8 所低收入社区的小学和 460 名儿童（8.5±0.6 岁，54%为女孩）。评估了儿童的基本运动技能水平（TGMD-2；6 项运动技能和 6 项物体控制技能）、客观测量的身体活动（ActiGraph GT3X 和 GT3X+加速度计）、身高、体重和人口统计学特征。使用多级线性混合模型来评估基本运动技能与 MVPA 之间的横断面关联。
结果
在调整年龄、性别、BMI 和社会经济地位后，运动技能水平与总 MVPA（P=0.002，r=0.15）和课后 MVPA（P=0.014，r=0.13）呈正相关。物体控制技能水平与总 MVPA（P<0.001，r=0.20）、午餐时间 MVPA（P=0.03，r=0.10）、课间休息 MVPA（P=0.006，r=0.11）和课后 MVPA（P=0.022，r=0.13）呈正相关。
结论
与运动技能相比，物体控制技能似乎是预测儿童在校内体育活动期间 MVPA 的更好指标。提高基本运动技能水平，特别是物体控制技能，可能有助于提高儿童全天的 MVPA 水平。
