背景有必要找到方法来增加体力活动水平和改善身体成分和血压的女孩。2005年春，30名11岁的女孩从德克萨斯州休斯顿的两个课后项目中被招募。一个项目的参与者（16人）被随机分配到干预组，另一个项目（14人）作为对照组。干预前后分别测量BMI、BMI百分位数、腰围和血压。在干预现场每天免费提供一小时的普拉提课程，每周5天，持续4周。四名参与者在每次会议期间都戴着心率监测器，并完成了享受和感知消耗问卷。以时间（组内）和组间（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 bpm，平均感觉劳累5.9（1-10量表）和享受4.4（1-5量表）。BMI百分位数存在显著（P = 0.039）的组间相互作用时间。图表显示，这种差异受到健康女孩BMI百分位数大幅降低的影响。女孩喜欢普拉提，参与4周降低BMI百分位数。普拉提有望成为减少肥胖的一种手段。(c)2005年爱思唯尔公司All rights reserved.
Background. There is a need to find ways to increase the physical activity levels and improve the body composition and blood pressure of girls.Methods. 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.Results. 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.Conclusions. Girls enjoyed Pilates, and participation for 4 weeks lowered BMI percentile. Pilates holds promise as a means of reducing obesity. (c) 2005 Elsevier Inc. All rights reserved.
