摘要
简介短道速滑(短道速滑)是一项奥林匹克运动,其特点是在赛道上采用特定的身体姿势和逆时针运动。根据以往的研究,我们假设运动员在这项运动中所采用的身体姿势可能会导致左下肢肌肉的非对称性过度使用性疾病。研究证实,短道速滑运动员左侧肢体超负荷运动时,个别肌肉中的潜在触发点(LTrPs)数量有所增加。本研究旨在比较短道速滑精英青少年运动员和健康非运动员的LTrPs数量和静息肌张力水平:实验(EXP)组由 15 名来自波兰国家队的短道速滑精英青少年运动员组成,对照(CON)组由 15 名健康的年轻志愿者组成。两组均测试了左腿(i)是否存在LTrPs和(ii)静息肌张力(RMT),采用表面肌电图对六块肌肉进行评估:结果:与 CON 组相比,EXP 组左下肢的 LTrPs 数量更多。运动员受影响最明显的肌肉是斜方肌[χ 2 (1, N = 30), p p = 0.033, Cohen's d = 0.87]:结论:与健康的非运动员相比,短道速滑青少年精英运动员的RMT和LTrPs数量均有所增加。
Resting muscle tension and trigger points in elite junior short-track athletes and healthy non-athletes: a cross-sectional examination.
Introduction: Short-track speed skating (short track) is an Olympic sport characterized by a specific body position and counterclockwise movement on the track. Based on previous studies, we hypothesized that athlete body positions employed in this sport could lead to asymmetric overuse disorders of the left lower limb muscles. An increased number of latent trigger points (LTrPs) was confirmed in individual muscles of the overloaded left limb of short-track athletes. This study aimed to compare the number of LTrPs and the level of resting muscle tone between elite junior short-track athletes and healthy non-athletes.
Methods: The experimental (EXP) group comprised 15 elite short-track junior athletes from the Polish national team and the control (CON) group comprised 15 healthy young volunteers. In both groups, the left leg was tested for (i) the presence of LTrPs and (ii) resting muscle tone (RMT), assessed using surface electromyography in six muscles.
Results: The EXP group showed a higher number of LTrPs in the left lower limb, compared with the CON group. The muscle that was most significantly affected in the athletes was the vastus lateralis obliquus [χ2 (1, N = 30), p < 0.001, V Cramer = 0.71]. This muscle also differed significantly between the groups in terms of the RMT (p = 0.033, Cohen's d = 0.87).
Conclusions: Elite short-track junior athletes presented with increased RMT and an increased number of LTrPs in the vastus lateralis oblique muscle, compared with healthy non-athletes.
