[Purpose] Very few studies have been conducted on the benefits of water exercise for older adults with sarcopenic obesity. Whether the water exercise intervention is effective for improving sarcopenia and/or obesity remains unclear. This study aimed to investigate the effects of water exercise on body composition and components of metabolic syndrome in older females with sarcopenic obesity. [Participants and Methods] Participants (aged ≥60 years) were divided into a water exercise group and a control group. Water-based strength and endurance exercises were performed three times a week for 12 weeks. Lean soft tissue mass, fat mass, and body fat percentage were measured by dual-energy x-ray absorptiometry. [Results] Two-way analysis of variance revealed significant interactions (time × group) for total body fat percentage and leg body fat percentage. In the exercise group, leg body fat percentage significantly decreased after the intervention, but no significant change was observed in the control group. The components of metabolic syndrome showed no significant interactions in either group (time × group). [Conclusion] No significant changes were observed in the components of metabolic syndrome. However, 12-week water exercise may be effective for reducing fat mass in females with sarcopenic obesity.
[目的] 针对患有肌肉减少性肥胖的老年人进行水上运动益处的研究非常少。水上运动干预对于改善肌肉减少症和/或肥胖是否有效仍不明确。本研究旨在探讨水上运动对患有肌肉减少性肥胖的老年女性身体成分和代谢综合征各组分的影响。[参与者与方法] 参与者（年龄≥60岁）被分为水上运动组和对照组。每周进行3次水上力量和耐力训练，共12周。通过双能X线吸收法测量瘦软组织质量、脂肪量和体脂百分比。[结果] 双向方差分析显示，全身脂肪百分比和腿部脂肪百分比存在显著的交互作用（时间×组间）。在运动组中，干预后腿部脂肪百分比显著降低，而对照组未观察到显著变化。代谢综合征的各组分在两组中均未显示出显著的交互作用（时间×组间）。[结论] 代谢综合征的各组分未观察到显著变化。然而，12周的水上运动可能对减少患有肌肉减少性肥胖的女性的脂肪量有效。
