The purpose of this study was to assess the effects of 8 weeks of modified hatha yoga training on physical fitness and stress level in injured workers.
Eighteen male and female injured workers, age between 18 and 55 years, participated in this study. They were divided into two groups: an additive hatha yoga training to routine industrial rehabilitation program group (HYG: n = 9) and a control group with no yoga training (CG: n = 9). A modified hatha yoga protocol was designed for this population by two certified yoga instructors, approved by a physical therapist, and conducted for 1 h, three times weekly for 8 weeks. Physical fitness variables including flexibility of lower back and hamstrings, hand grip strength and lung capacity and scores of sensitivity to stress were evaluated at the time of recruitment and after 8 weeks of intervention.
The values of all physical fitness variables and stress scores were no significant difference between the two groups at baseline. Significant post-yoga improvements for HYG group were noted in flexibility, hand grip strength, and vital capacity (p < 0.05). In contrast, there was no significant change in the CG group. Stress scores did not change as a result of hatha yoga training.
An 8-week modified hatha yoga training experience exerted therapeutic effects on physical fitness variables including flexibility of lower back and hamstrings, hand grip strength and vital capacity, but not on stress level in injured workers. These findings indicate that hatha yoga can be a beneficial adjunct to routine physical therapy treatment in industrial rehabilitation programs.
本研究旨在评估为期8周的改良哈他瑜伽训练对受伤工人身体素质和压力水平的影响。
18名年龄在18至55岁之间的男女受伤工人参与了本研究。他们被分为两组：一组为在常规工业康复计划基础上增加哈他瑜伽训练组（HYG组：n = 9），另一组为无瑜伽训练的对照组（CG组：n = 9）。两名认证瑜伽教练为该人群设计了改良哈他瑜伽方案，经物理治疗师批准，每周进行3次，每次1小时，共持续8周。在招募时和干预8周后，评估了包括下背部和腘绳肌柔韧性、握力、肺活量等身体素质变量以及压力敏感度得分。
两组在基线时所有身体素质变量和压力得分均无显著差异。HYG组在瑜伽训练后，柔韧性、握力和肺活量有显著改善（p < 0.05）。相比之下，CG组无显著变化。哈他瑜伽训练后压力得分未改变。
为期8周的改良哈他瑜伽训练对受伤工人的身体素质变量，如下背部和腘绳肌柔韧性、握力和肺活量有治疗效果，但对压力水平无影响。这些发现表明，哈他瑜伽可以成为工业康复计划中常规物理治疗的有益辅助手段。
