We aimed to investigate the effect of stretching exercises applied to the hamstring, one of the posterior muscle chains, on musculoskeletal flexibility, chest mobility, and respiratory function. Proprioceptive neuromuscular facilitation and static stretching exercises were applied to 30 healthcare personnel caring for children with developmental delays using a crossover randomized study design. Posterior muscle chain mobility was assessed using the popliteal angle test (PAT) for the hamstring muscle, the mobility of the lumbar muscles was assessed using the Schober test (ST), and the mobility of the posterior chain muscles as a whole was assessed using the finger-to-floor distance test. Chest mobility was measured using chest circumference measurements and lung volumes were measured using the pulmonary function test (PFT). The results showed that stretching exercises applied to the hamstrings led to significant improvements in PAT, ST, and chest mobility in the direction of maximal expiration ( < 0.05), without being superior to each other. Ten males (33.3%) and twenty females (66.7%) who met the inclusion criteria were analyzed. The mean age of the participants was 26.6 ± 5.9 years, the mean height was 169.53 ± 8.67 cm, the mean weight was 65.26 ± 12.03 kg, and the mean body mass index was 22.58 ± 3 kg/m. Chest inspiratory mechanics also showed a low positive correlation with posterior muscle mobility (r = 0.381; = 0.038). There was no significant change in PAT. Within the framework of the myofascial theory, stretching exercises that can contribute positively to the musculoskeletal and respiratory system structures of healthcare professionals can be recommended and encouraged to healthcare professionals.
本研究旨在探讨伸展运动对下肢后链肌肉（包括腘绳肌）的影响，以评估其对肌肉骨骼柔韧性、胸部活动度和呼吸功能的影响。采用交叉随机研究设计，对 30 名照顾发育迟缓儿童的医护人员进行了本体感受神经肌肉促进法和静态伸展运动。使用腘绳肌 popliteal angle test (PAT) 评估后链肌肉的柔韧性，使用 Schober test (ST) 评估腰椎的活动度，使用手指触地距离测试评估整个后链肌肉的活动度。通过胸围测量评估胸部活动度，通过肺功能测试 (PFT) 测量肺容积。结果表明，伸展运动可显著改善 PAT、ST 和最大呼气时的胸部活动度（<0.05），但彼此之间没有差异。纳入分析的有 10 名男性（33.3%）和 20 名女性（66.7%）。参与者的平均年龄为 26.6 ± 5.9 岁，平均身高为 169.53 ± 8.67cm，平均体重为 65.26 ± 12.03kg，平均身体质量指数为 22.58 ± 3kg/m²。胸部吸气力学也与后链肌肉的活动度呈低度正相关（r=0.381；=0.038）。PAT 无显著变化。在筋膜理论的框架内，可以推荐和鼓励医护人员进行伸展运动，以积极促进其肌肉骨骼和呼吸系统结构的健康。
