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.
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.
Group 1 had significant improvements in the posttreatment EORTC QLQ functional and global scores (p < 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 > 0.05). Comparison of the 2 groups revealed no differences.
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.
相位角（PA）是一种通过身体成分分析获得的参数，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）下降，并增加死亡率。研究表明，身体活动会增加 PA。在这项研究中，我们旨在研究哈他瑜伽对乳腺癌患者 PA、身体成分和生活质量的影响。
31 名患者被随机分为瑜伽组（1 组，n = 15）和对照组（2 组，n = 16）。干预组每周进行两次哈他瑜伽，共 10 周。使用身体分析仪器评估患者的 PA，使用 EORTC QLQ 问卷在治疗前和第 10 周评估 QoL。
1 组在治疗后 EORTC QLQ 功能和整体评分显著改善（p < 0.05）。2 组在 EORTC QLQ 症状子量表上观察到显著改善（p = 0.035）。两组的 PA 值均无改善（p > 0.05）。两组间的比较没有差异。
瑜伽可能对乳腺癌患者的生活质量有有益的影响，但对 PA 没有显著影响。需要进一步的研究来做出明确的结论。
