A Yoga-asana-based intervention has demonstrated its ability to improve flexibility of individuals, but has not been explored in rugby players. We hypothesized that a structured yoga intervention may have an effect on flexibility and sprint performance in male rugby union players.
It was a controlled trial research design and players were assigned using random sampling to one of the two groups; a yoga group ( = 16) that practised yoga for 1 h 2 times a week for 8 weeks in addition to their normal rugby training and a control group ( = 15) with regular rugby training but no yoga intervention. Yoga intervention included 32 yoga postures to address both the upper and lower extremities of the body. Data were collected during preseason and mid-season on hamstring flexibility (sit and reach test), and sprint performance (measured at 5, 10, and 30 m).
One hundred and twenty participants were screened and thirty-one players volunteered for the study. Interactions between groups and differences between pre- and post-intervention scores were analyzed using analysis of variance using SPSS (version 24.0). Significance was set at an alpha level of = 0.05. The yoga group showed a small nonsignificant decrease (-1.2% ± 21.4%, = 0.05) in hamstring flexibility compared to the control group which demonstrated a large significant decrease (-14.8% ± 23.7%) (mean % change ± 95% confidence interval [CI], < 0.05). The yoga group also showed minor nonsignificant improvements in sprint times -3.2% ± 10.4%, -0.7% ± 9.0% for the 5 and 10 m sprints, respectively, (mean % change ± 95% CI) compared to controls -0.4% ± 10.2%, 0.4% ± 7.9%.
Findings suggest that completing a structured yoga intervention alongside normal rugby training during the rugby season, yoga helped rugby players maintain their hamstring flexibility but did little to improve sprint performance during the season.
基于瑜伽体式的干预已证明其能够提高个体的柔韧性，但尚未在橄榄球运动员中进行探索。我们假设，结构化的瑜伽干预可能会对男子英式橄榄球联盟球员的柔韧性和短跑成绩产生影响。
这是一项对照试验研究设计，通过随机抽样将球员分配到两组之一；瑜伽组（n = 16），除了正常的橄榄球训练外，每周进行2次1小时的瑜伽练习，持续8周；对照组（n = 15），进行常规橄榄球训练但无瑜伽干预。瑜伽干预包括32种瑜伽体式，涉及身体的上下肢。在季前赛和赛季中期收集数据，包括腘绳肌柔韧性（坐立前屈测试）和短跑成绩（在5米、10米和30米处测量）。
筛选了120名参与者，31名球员自愿参加该研究。使用SPSS（版本24.0）通过方差分析对组间相互作用以及干预前后得分差异进行分析。显著性设定为α水平 = 0.05。与对照组相比，瑜伽组的腘绳肌柔韧性有小幅不显著下降（-1.2% ± 21.4%，p = 0.05），而对照组则有大幅显著下降（-14.8% ± 23.7%）（平均变化百分比 ± 95%置信区间[CI]，p < 0.05）。与对照组相比，瑜伽组在5米和10米短跑的时间上也有轻微不显著的改善，分别为-3.2% ± 10.4%、-0.7% ± 9.0%（平均变化百分比 ± 95% CI），而对照组为-0.4% ± 10.2%、0.4% ± 7.9%。
研究结果表明，在橄榄球赛季期间，在正常橄榄球训练的同时完成结构化的瑜伽干预，瑜伽有助于橄榄球运动员保持腘绳肌柔韧性，但对赛季期间的短跑成绩改善作用不大。
