This study examined the feasibility and comparison of two styles of yoga within the context of a standard behavioral weight-loss intervention (SBWI).
Fifty adults with obesity (BMI: 31.3 ± 3.8 kg/m ) participated in this 6-month study that included a SBWI and a calorie- and fat-reduced diet. Randomization was to restorative Hatha (SBWI+RES) or Vinyasa (SBWI+VIN) yoga. Yoga was prescribed to increase from 20 to 40 to 60 minutes per session across the intervention. Weight was assessed at baseline and 6 months. Perceptions of yoga were assessed at the completion of the intervention.
Adjusted weight loss was -3.4 kg (95% CI: -6.4 to -0.5) in SBWI+RES and -3.8 kg (95% CI: -6.8 to -0.9) in SBWI+VIN (P < 0.001), with no difference between groups. Of all participants, 74.4% reported that they would continue participation in yoga after the SBWI. Session duration was a barrier as yoga increased from 20 to 40 to 60 minutes per day, with 0%, 7.5%, and 48.8% reporting this barrier, respectively.
Among adults with obesity, yoga participation, within the context of a SBWI, appears to be feasible, with weight loss not differing by style of yoga. Progressing to 60 minutes per session appears to be a barrier to engagement in yoga in this population.
本研究在标准行为减肥干预（SBWI）的背景下，考察了两种瑜伽方式的可行性及比较情况。
五十名肥胖成年人（BMI：31.3±3.8kg/m²）参与了这项为期6个月的研究，该研究包括SBWI以及减少热量和脂肪的饮食。随机分为恢复性哈他瑜伽组（SBWI+RES）或流瑜伽组（SBWI+VIN）。在整个干预过程中，规定瑜伽课程时长从每次20分钟增加到40分钟再到60分钟。在基线和6个月时评估体重。在干预结束时评估对瑜伽的看法。
SBWI+RES组调整后的体重减轻为-3.4kg（95%CI：-6.4至-0.5），SBWI+VIN组为-3.8kg（95%CI：-6.8至-0.9）（P<0.001），两组之间无差异。在所有参与者中，74.4%报告称在SBWI结束后他们会继续参与瑜伽。随着瑜伽课程时长从每天20分钟增加到40分钟再到60分钟，课程时长成为了一个障碍，分别有0%、7.5%和48.8%的人报告了这一障碍。
在肥胖成年人中，在SBWI的背景下参与瑜伽似乎是可行的，体重减轻情况不因瑜伽方式而异。在该人群中，每次课程时长增加到60分钟似乎是参与瑜伽的一个障碍。
