Abstract：
Objective: Rapid bone development in growing children causes excessive tension in the lower extremities\' muscles and tendons, leading to reduced flexibility and increased musculoskeletal disorder risk. Further, lack of exercise causes obesity. Therefore, we created a stretching exercise protocol to prevent musculoskeletal disorders in elementary school (middle and upper grades) children during their growth period, when rapid bone development begins. Patients and Methods: We examined the effects on pain, injury, and flexibility. Fifty-three (boys: 34, girls: 19) students in grades 3-5 (ages 9-11) performed the stretching exercises at school thrice a week for one year, and we compared the results before and a year after the intervention. Results: A three-minute stretching exercise routine achieved an intensity of 4.6-4.9 metabolic equivalents (METs; equivalent to brisk walking). Obesity (P=1.000), flexibility problems (inability to bend forward [P=0.754] or squat problems [P=1.000]), bone/joint pain (P=1.000), and injury (P=1.000) did not significantly increase. Conclusion: Stretching exercises during the growth period may help prevent childhood musculoskeletal disorders, obesity, and flexibility loss.
摘要：
目的：儿童骨骼的快速发育会导致下肢肌肉和肌腱过度紧张，导致灵活性降低和肌肉骨骼疾病风险增加。Further,缺乏运动会导致肥胖。因此,我们制定了一项伸展运动方案，以防止小学（中高年级）儿童在其生长期的肌肉骨骼疾病，当快速骨骼发育开始时。患者和方法：我们检查了对疼痛的影响，损伤,和灵活性。53名（男孩：34，女孩：19）3-5年级（9-11岁）的学生在学校进行了为期一年的每周三次的伸展运动，我们比较了干预前后一年的结果。结果：三分钟的伸展运动程序达到了4.6-4.9代谢当量（MET；相当于快走）的强度。肥胖（P=1.000），柔韧性问题（无法向前弯曲[P=0.754]或下蹲问题[P=1.000]），骨/关节痛（P=1.000），损伤（P=1.000）没有明显增加。结论：在生长期进行伸展运动可能有助于预防儿童肌肉骨骼疾病，肥胖，失去灵活性。
