There is a need to find ways to increase the physical activity levels and improve the body composition and blood pressure of girls.
Thirty 11-year-old girls were recruited from two after school programs in Houston Texas in Spring 2005. Participants from one program (16) were randomly assigned to intervention, the other (14) served as controls. BMI, BMI percentile, waist circumference and blood pressure were assessed before and after the intervention. Pilates classes were provided free of charge for an hour per day at the intervention site, 5 days a week, for 4 weeks. Four participants wore heart rate monitors during every session and completed enjoyment and perceived exertion questionnaires. Repeated measures analysis of variance with time (within) and group (between) as factors was performed.
Mean attendance was 75%, mean heart rate 104 bpm, mean perceived exertion 5.9 (1-10 scale) and enjoyment 4.4 (1-5 scale). There was a significant (P = 0.039) time by group interaction for BMI percentile. Graphs indicated that this difference was influenced by large reductions in the BMI percentile of healthy girls.
Girls enjoyed Pilates, and participation for 4 weeks lowered BMI percentile. Pilates holds promise as a means of reducing obesity.
需要找到提高女孩身体活动水平、改善身体成分和血压的方法。
2005年春季，从得克萨斯州休斯敦的两个课外项目中招募了30名11岁女孩。其中一个项目的16名参与者被随机分配到干预组，另一个项目的14名参与者作为对照组。在干预前后评估体重指数（BMI）、BMI百分位数、腰围和血压。干预组每天免费提供一小时的普拉提课程，每周5天，共4周。4名参与者在每次课程中佩戴心率监测器，并完成了关于课程趣味性和主观用力程度的问卷调查。以时间（组内）和组（组间）为因素进行重复测量方差分析。
平均出勤率为75%，平均心率为104次/分钟，平均主观用力程度为5.9（1 - 10分制），趣味性评分为4.4（1 - 5分制）。BMI百分位数存在显著的（P = 0.039）组间与时间的交互作用。图表显示，这种差异受到健康女孩BMI百分位数大幅下降的影响。
女孩们喜欢普拉提，参与4周可降低BMI百分位数。普拉提有望成为一种减少肥胖的方法。
