虽然女孩的身体活动一般比男孩少，但有些女孩经常进行高水平的身体活动;然而，人们对这些女孩以及她们与身体活动较少的女孩的区别知之甚少。本研究探讨了PA的行为和高度活跃的青春期女孩的相关特征，并将其与那些不太活跃的人进行了比较。METHODSData从1,866八年级的女孩从六个外地中心在美国各地参加了青春期女孩的活动试验（TAAG）包括在本分析。混合模型方差分析研究了高活动和低活动女孩之间的社会人口统计学，人体测量学，心理社会学和身体活动（加速度计和自我报告）变量的差异;计算了差异的效应量。高活跃的女孩得分较高的自我效能感，享受PA，自我管理策略，结果期望值，并从家庭和朋友的支持比低活跃的女孩。低活动的女孩比高活动的女孩参加更多的休闲时间和教育久坐活动。高活跃的女孩参加了更多的PA类/课外课程，团队运动，和个人运动。他们也更有可能参加体育运动在一个有组织的环境中，在社区或在学校比低活性的girls. CONCLUSIONSHALTH促进工作的重点应放在减少的时间女孩花在久坐不动的活动，并取代有组织的PA机会的时间，这种努力应力求尽量减少感知障碍，提高自我效能和支持PA。
PURPOSEAlthough girls are generally less physically active than boys, some girls regularly engage in high levels of physical activity (PA); however, very little is known about these girls and how they differ from those who are less physically active. This study examined the PA behavior and related characteristics of highly active adolescent girls and compared them with those who are less active.METHODSData from 1,866 eighth-grade girls from six field centers across the United States participating in the Trial of Activity for Adolescent Girls (TAAG) were included in the present analysis. Mixed-model analysis of variance examined differences in sociodemographic, anthropometric, psychosocial, and physical activity (accelerometry and self-report) variables between high- and low-active girls; effect sizes were calculated for the differences.RESULTSHigh-active girls were taller, had lower body mass indices and body fat, and were less sedentary. High-active girls scored higher on self-efficacy, enjoyment of PA, self-management strategies, outcome-expectancy value, and support from family and friends than low-active girls. Low-active girls participated in more leisure time and educational sedentary activities than high-active girls. High-active girls participated in more PA classes/lessons outside of school, team sports, and individual sports. They were also more likely to participate in sports in an organized setting in the community or at school than low-active girls.CONCLUSIONSHealth promotion efforts should focus on decreasing the amount of time girls spend in sedentary activities and replacing that time with organized PA opportunities; such efforts should seek to minimize perceived barriers and increase self-efficacy and support for PA.
