Casey AF、Rasmussen R、Mackenzie SJ、Glenn J。双能 X 射线吸收测量法测量 16 周社区游泳训练计划对智障儿童和青少年身体脂肪的影响。 Arch Phys Med Rehabil 2010;91:1064-9。目的：使用双能 X 射线吸收测定法 (DXA) 测量为期 16 周的社区游泳训练计划对智力障碍儿童和青少年 (ID) 体脂百分比的影响。设计：方便样本。设置：大学体育中心和运动科学实验室。参与者：儿童和青少年（n=8；平均年龄 +/- SD， 13.1 +/- 3.4 岁），2 名女孩和 6 名男孩患有智力障碍，脂肪水平不同（11%-35%）。干预：持续 16 周的游泳训练计划，每周在 25 米泳池举行 3 次每次 1 小时的课程。主要结果测量：通过使用 DXA 评估测试前和测试后的身体脂肪百分比。结果：在 16 周的运动训练计划之后，我们观察到体脂百分比中位数增加 1.2%，范围为 -0.3% 至 4.5%。 Wilcoxon 配对符号排序检验表明，这些结果具有统计显着性（P=0.039；准确）。结论：事实证明，仅运动训练对于降低 8 名智力障碍儿童和青少年的体脂百分比是无效的。进一步的研究应考虑实施饮食和锻炼相结合的计划。为了衡量干预计划的有效性，应使用有效的方法和复杂的测量工具（例如 DXA）来评估此类异质人群的体脂百分比变化。

Dual-energy x-ray absorptiometry to measure the influence of a 16-week community-based swim training program on body fat in children and adolescents with intellectual disabilities. Arch Phys Med Rehabil 2010;91:1064-9.Objective: To use dual-energy x-ray absorptiometry (DXA) to measure the effects of a 16-week community-based swim training program on percent body fat in children and adolescents with intellectual disability (ID).Design: Convenience sample.Setting: University sport complex and exercise science laboratory.Participants: Children and adolescents (n=8; mean age +/- SD, 13.1 +/- 3.4y), 2 girls and 6 boys with ID, of varying fat levels (11%-35%).Intervention: A swim training program lasting for the duration of 16 weeks with three 1-hour sessions held at a 25-m pool each week.Main Outcome Measure: Assessing percent body fat at pretest and posttest through the use of DXA.Results: After the 16-week exercise training program, we observed a 1.2% median increase in body fat percentage with a range from -0.3% to 4.5%. Wilcoxon matched-pairs signed-ranks tests suggest that these results are statistically significant (P=.039; exact).Conclusions: Exercise training alone proved ineffectual in reducing percent body fat in 8 children and adolescents with ID. Further research should consider implementing a combined diet and exercise program. To gauge the effectiveness of intervention programs, valid methods and complex measurement tools such as DXA should be used to assess changes in percent body fat in such a heterogeneous population.
