OBJECTIVE
To evaluate social support and theory of planned behavior (TPB) constructs in explaining physical activity in adolescent girls.
METHODS
One thousand seven hundred ninety-seven 8th-grade girls completed a survey measuring social provisions, family support, TPB constructs, moderate-to-vigorous physical activity (MVPA), and team sport involvement (TSI).
RESULTS
Structural equation modeling (SEM) indicated statistically significant direct effects from TPB constructs and social provisions to intention; social provisions, family support, and intention to MVPA; and social provisions and family support to TSI.
CONCLUSIONS
Social variables play a greater role in explaining TSI than in explaining MVPA in this sample.
目的
评估社会支持和计划行为理论（TPB）结构在解释少女身体活动方面的作用。
方法
1797名八年级女生完成了一项调查，该调查测量了社会支持、家庭支持、TPB结构、中度至剧烈身体活动（MVPA）和团队运动参与度（TSI）。
结果
结构方程模型（SEM）表明，TPB结构和社会支持对意图有统计学上显著的直接影响；社会支持、家庭支持和对MVPA的意图；以及社会支持和家庭支持对TSI。
结论
在这个样本中，社会变量在解释TSI方面比在解释MVPA方面发挥更大的作用。
