The purpose of this study was to investigate the effect of 16 weeks of Bikram yoga on perceived stress, self-efficacy and health related quality of life (HRQoL) in sedentary, stressed adults.
16 week, parallel-arm, randomised controlled trial with flexible dosing.
Physically inactive, stressed adults (37.2±10.8 years) were randomised to Bikram yoga (three to five classes per week) or control (no treatment) group for 16 weeks. Outcome measures, collected via self-report, included perceived stress, general self-efficacy, and HRQoL. Outcomes were assessed at baseline, midpoint and completion.
Individuals were randomised to the experimental (n=29) or control group (n=34). Average attendance in the experimental group was 27±18 classes. Repeated measure analyses of variance (intention-to-treat) demonstrated significantly improved perceived stress (p=0.003, partial η=0.109), general self-efficacy (p=0.034, partial η=0.056), and the general health (p=0.034, partial η=0.058) and energy/fatigue (p=0.019, partial η=0.066) domains of HRQoL in the experimental group versus the control group. Attendance was significantly associated with reductions in perceived stress, and an increase in several domains of HRQoL.
16 weeks of Bikram yoga significantly improved perceived stress, general self-efficacy and HRQoL in sedentary, stressed adults. Future research should consider ways to optimise adherence, and should investigate effects of Bikram yoga intervention in other populations at risk for stress-related illness.

本研究旨在调查16周的高温瑜伽对久坐不动、压力大的成年人的感知压力、自我效能感和健康相关生活质量（HRQoL）的影响。
为期16周的平行组随机对照试验，剂量灵活。
身体不活跃、压力大的成年人（37.2±10.8岁）被随机分为高温瑜伽组（每周三至五节课）或对照组（不进行治疗），为期16周。通过自我报告收集的结果指标包括感知压力、一般自我效能感和健康相关生活质量。在基线、中点和结束时评估结果。
个体被随机分为实验组（n=29）或对照组（n=34）。实验组的平均出勤次数为27±18节。重复测量方差分析（意向性分析）表明，与对照组相比，实验组的感知压力（p=0.003，偏η=0.109）、一般自我效能感（p=0.034，偏η=0.056）以及健康相关生活质量的总体健康（p=0.034，偏η=0.058）和精力/疲劳（p=0.019，偏η=0.066）领域有显著改善。出勤与感知压力的降低以及健康相关生活质量几个领域的提高显著相关。
16周的高温瑜伽显著改善了久坐不动、压力大的成年人的感知压力、一般自我效能感和健康相关生活质量。未来的研究应考虑优化依从性的方法，并应调查高温瑜伽干预对其他有与压力相关疾病风险人群的影响。
