Introduction: Phase angle (PA), a parameter that is obtained from body composition analysis, is an indicator of cellular health status. A lower PA in cancer patients can lead to a decrease in functional status and quality of life (QoL) and increased mortality. Studies have shown that physical activity increases PA. In this study, we aimed to examine the effects of Hatha yoga on PA, body composition, and QoL in patients with breast cancer. Methods: Thirty-one patients were randomized into the yoga (group 1, n = 15) and the control group (group 2, n = 16). Hatha yoga was practiced twice a week for 10 weeks in the intervention group. The PA of the patients was assessed using a body analysis instrument, and QoL was evaluated with an EORTC QLQ questionnaire both before treatment and at week 10. Results: Group 1 had significant improvements in the posttreatment EORTC QLQ functional and global scores (p #x3c; 0.05). In group 2, a significant improvement was observed in the EORTC QLQ symptom subscale (p = 0.035). PA values did not show any improvements in both groups (p #x3e; 0.05). Comparison of the 2 groups revealed no differences. Conclusion: Yoga may have beneficial effects on QoL in patients with breast cancer but does not have a significant effect on PA. There is a need for further studies to make a definitive statement.

瑜伽对乳腺癌患者相位角和生活质量的影响：一项随机、单盲、对照试验

简介：相位角 (PA) 是从身体成分分析中获得的参数，是细胞健康状况的指标。癌症患者较低的 PA 会导致功能状态和生活质量 (QoL) 的下降以及死亡率的增加。研究表明，体育锻炼会增加 PA。在这项研究中，我们旨在检查哈他瑜伽对乳腺癌患者的 PA、身体成分和 QoL 的影响。方法：将 31 名患者随机分为瑜伽组（第 1 组， n = 15）和对照组（第 2 组， n= 16）。干预组每周练习两次哈他瑜伽，持续 10 周。使用身体分析仪器评估患者的 PA，并在治疗前和第 10 周使用 EORTC QLQ 问卷评估 QoL。结果：第 1 组治疗后 EORTC QLQ 功能和整体评分有显着改善 ( p #x3c ; 0.05)。在第 2 组中，观察到 EORTC QLQ 症状分量表有显着改善（p = 0.035）。两组的 PA 值均未显示任何改善（p #x3e；0.05）。两组的比较显示没有差异。结论：瑜伽可能对乳腺癌患者的 QoL 有益，但对 PA 没有显着影响。需要进一步的研究才能做出明确的陈述。
