儿童的运动技能能力（MSC），知觉能力（PC），体力活动（PA）和心肺功能（CRF）之间的双向关联随着时间的推移仍然没有答案。本研究旨在探讨国小学童在一个学年内，其MSC、PC、PA与CRF之间的双向关系。 从德克萨斯州的两所小学共招募了261名二年级和三年级儿童（127名男孩，134名女孩;平均年龄= 8.27岁; BMI = 18.22 ± 3.71）。大约73.56%的参与者是白色美国人。儿童的基线数据在2012年9月/10月进行评估（时间1），在2013年4月/5月进行相同的评估（时间2）。使用面向产品的技能测试（例如，扔，踢，跳）。PC通过儿童感知能力的图片量表进行评估。使用ActiGraph GT 3X+加速度计连续5天评估中度至剧烈PA（MVPA）的分钟数，并通过PACER测试评估CRF。六个年龄和身体质量指数调整交叉滞后面板模型被用来测试变量之间的关系。 我们观察到T1 MSC显著预测T2 MSC（β = 0.59; p < 0.01）、T2 CRF（β = 0.28; p < 0.01）和T2 MVPA（β = 0.18; p < 0.01）。儿童CRF是T2 CRF（β = 0.56; p < 0.01）和T2 MSC（β = 0.13; p < 0.05）的阳性预测因子。此外，T1 MVPA显著预测T2 MVPA（β = 0.30; p < 0.01）和T2 PC（β =-0.14; p < 0.05）。 研究结果表明，小学儿童的MSC和CRF之间的双向关系。变量之间的其他双向关系仅得到部分支持。教育工作者和卫生专业人员需要强调发展MSC和CRF的重要性，以保持身体健康。
The bidirectional associations among children's motor skill competence (MSC), perceived competence (PC), physical activity (PA), and cardiorespiratory fitness (CRF) over time remain unanswered. This study is aimed at discerning the bidirectional relationships among elementary school children's MSC, PC, PA and, CRF over the course of one school year. A total of 261 second and third grade children (127 boys, 134 girls; meanage = 8.27 years; BMI = 18.22 ± 3.71) were recruited from two Texas elementary schools. Approximately 73.56% of participants were White American. Children's baseline data were assessed in September/October in 2012 (Time1), and identical assessments were conducted in April/May in 2013 (Time2). MSC was assessed using product-oriented skill tests (e.g., throw, kick, and jump). PC was assessed via the Pictorial Scale of Perceived Competence for Children. Minutes spent in moderate-to-vigorous PA (MVPA) was assessed using ActiGraph GT3X+ accelerometers for five days, and CRF was assessed by the PACER test. Six age- and body mass index-adjusted cross-lagged panel models were used to test the relationships between the variables. We observed that T1 MSC significantly predicted T2 MSC (β = 0.59; p < 0.01), T2 CRF (β = 0.28; p < 0.01), and T2 MVPA (β = 0.18; p < 0.01). Children's CRF was a positive predictor for T2 CRF (β = 0.56; p < 0.01) and T2 MSC (β = 0.13; p < 0.05) Additionally, T1 MVPA significantly predicted T2 MVPA (β = 0.30; p < 0.01) and T2 PC (β = −0.14; p < 0.05). Findings suggested a fully bidirectional relationship between elementary children's MSC and CRF. Other bidirectional relationships among the variables were only partially supported. Educators and health professionals need to emphasize the importance of developing both MSC and CRF to maintain physical health over time.
