DANCE IN THE TREATMENT OF CHILDHOOD OBESITY: A PROPOSED PROTOCOL

ABSTRACT Introduction: Low levels of daily physical activity is considered to be one of the causes of the exorbitant increase in overweight and obese children, and associated comorbidities. Therefore, it is vital to develop strategies that will be implemented consistently, to improve this situation. Studies have used dance as a resource for training overweight and obese children, but the lack of information about the creation process and its respective stages reduce the possibility of these proposals being effectively applied. Objectives: To describe the steps in the creation of a dance protocol as a training resource, and its effectiveness in improving the health parameters of overweight and obese children. Methods: 30 children (9 ± 1.1 years) underwent training sessions consisting of a five-minute warm-up at 60% HRmax., and four 10-minute sessions at 70% to 80% at HRmax. interspersed with five 2-minute active recovery periods at 60% HRmax. The sessions were carried out three times a week, and lasted 60 minutes each, over a 13-week period. Before and after the training, the body composition, body mass index (BMI), BMI z-score, waist circumference (WC), waist-to-height ratio (WHtR), systolic (SBP) and diastolic (DBP) blood pressure and blood variables were measured. Statistical analysis was performed using a mixed effects regression model. Results: After training with Afro-Brazilian dance, there was a significant reduction (p<0.05) in the BMI z-score and waist-to-height ratio. Conclusion: Afro-Brazilian dance training was a strategy with a positive effect on BMI z-score and waist-to-height ratio in overweight and obese children. Level of evidence IV; Case series.摘要 引言：日常体力活动水平低下被认为是超重与肥胖儿童比例激增及其相关合并症发生的重要诱因之一。因此，制定可长期持续推行的干预策略以改善这一现状至关重要。现有研究已将舞蹈作为超重与肥胖儿童的训练手段，但目前缺乏关于该训练方案创建流程及各实施阶段的详细信息，这限制了此类方案的有效落地应用。 研究目的：详述作为训练资源的舞蹈方案的创建步骤，并评估其对超重与肥胖儿童健康指标的改善效果。 研究方法：本研究纳入30名年龄为9±1.1岁的儿童，训练课程设置如下：以60%最大心率（Heart Rate Maximum，HRmax）进行5分钟热身，随后进行4组每组10分钟、强度为70%~80% HRmax的训练，每组训练间隙穿插5分钟、强度为60% HRmax的主动恢复环节。训练每周进行3次，每次时长60分钟，全程持续13周。在训练前后，分别测量受试者的身体成分、体重指数（Body Mass Index，BMI）、BMI z评分、腰围（Waist Circumference，WC）、腰围身高比（Waist-to-Height Ratio，WHtR）、收缩压（Systolic Blood Pressure，SBP）与舒张压（Diastolic Blood Pressure，DBP），以及血液相关指标。统计分析采用混合效应回归模型完成。 研究结果：经非裔巴西舞蹈训练后，受试者的BMI z评分与腰围身高比均出现显著降低（p<0.05）。 研究结论：非裔巴西舞蹈训练可有效改善超重与肥胖儿童的BMI z评分及腰围身高比，是一项具备积极干预效果的策略。证据等级：IV级；病例系列研究。
