背景资料：本研究的目的是描述的体育活动水平的女孩在舞蹈课，并确定与中等到剧烈的体育活动（MVPA）在这些类的因素。方法：参与者是137名女孩（11至18岁）参加芭蕾舞，爵士舞，或踢踏舞班从11个舞蹈工作室。参与者在2个不同的日子里在选定的舞蹈课上戴着加速计。假设与MVPA相关的因素是舞蹈风格，教学水平，教师的经验，在编舞中花费的课堂时间的百分比，和参与者的年龄，种族/民族，BMI的年龄百分位数，和舞蹈训练年。使用广义线性混合模型分析数据。结果如下：女孩从事9.8分钟的MVPA，6.0分钟的中度，3.8分钟的激烈，39.3分钟的光，和10.9分钟的久坐行为每小时的舞蹈课参与。爵士乐/踢踏舞班比芭蕾舞班提供更多的MVPA，中级班比高级班提供更多的MVPA。舞蹈训练较多的女孩比舞蹈训练较少的女孩获得更多的MVPA。结论：舞蹈班为青春期女孩提供了宝贵的机会，使她们能够积极参加体育活动。
Background: The aims of this study were to describe the physical activity levels of girls during dance classes and to identify factors associated with moderate-to-vigorous physical activity (MVPA) in those classes. Methods: Participants were 137 girls (11 to 18 years-old) enrolled in ballet, jazz, or tap dance classes from 11 dance studios. Participants wore an accelerometer during the selected dance class on 2 separate days. Factors hypothesized to be associated with MVPA were dance style, instructional level, instructor's experience, percent of class time spent in choreography, and participants' age, race/ethnicity, BMI-for-age percentile, and years of dance training. Data were analyzed using generalized linear mixed models. Results: Girls engaged in 9.8 minutes of MVPA, 6.0 minutes of moderate, 3.8 minutes of vigorous, 39.3 minutes of light, and 10.9 minutes of sedentary behavior per hour of dance class participation. Jazz/tap classes provided more MVPA than ballet classes, and intermediate level classes provided more MVPA than advanced level classes. Girls with more dance training obtained more MVPA than girls with less dance training. Conclusion: Dance classes provide valuable opportunities for adolescent girls to be physically active.
