The incidence of low back pain (LBP) is high among high school male soft tennis players. In some sports for which the rotational component of the body is important, an association between restricted hip internal rotation of the nondominant leg and LBP has been reported; however, whether this association holds in soft tennis is unknown. Therefore, this study aimed to evaluate the association between hip internal rotation, hip external rotation, hamstring flexibility, iliopsoas flexibility, and LBP incidence.
This study was designed as a cross-sectional study, conducted at a sports training center.
Participants comprised 113 male elite high school soft tennis players (age: 16.1 [0.7] y) from 9 elite-level teams. The main outcome measures were the hip internal and external rotation range of motion, hamstring flexibility on the straight leg raise test, and iliopsoas flexibility on the Thomas test. Multiple logistic regression analysis was performed to examine the influence of main outcomes on LBP incidence in the past 1 year.
A total of 35 participants had LBP (LBP group); 78 participants did not have LBP (non-LBP group). Multiple logistic regression analysis revealed that the odds ratio for height was 1.08 (95% confidence interval, 1.00-1.16; P = .043) and for the hip internal rotation range of motion in the nondominant leg was 0.90 (95% confidence interval, 0.85-0.95; P < .001), indicating significant associations with LBP.
Hip internal rotation range of motion in the nondominant leg and height were crucial factors related to LBP in male elite high school soft tennis players.
高中男子软式网球运动员中腰痛（LBP）的发生率较高。在一些身体旋转动作较为重要的运动中，已有报道称非优势腿髋关节内旋受限与腰痛之间存在关联；然而，这种关联在软式网球运动中是否成立尚不清楚。因此，本研究旨在评估髋关节内旋、外旋、腘绳肌柔韧性、髂腰肌柔韧性与腰痛发生率之间的关联。
本研究设计为一项在体育训练中心进行的横断面研究。
研究对象包括来自9支精英水平球队的113名高中男子软式网球精英运动员（年龄：16.1[0.7]岁）。主要观察指标为髋关节内旋和外旋活动范围、直腿抬高试验中的腘绳肌柔韧性以及托马斯试验中的髂腰肌柔韧性。采用多元逻辑回归分析来检验主要观察指标对过去1年中腰痛发生率的影响。
共有35名参与者患有腰痛（腰痛组）；78名参与者没有腰痛（无腰痛组）。多元逻辑回归分析显示，身高的比值比为1.08（95%置信区间，1.00 - 1.16；P = 0.043），非优势腿髋关节内旋活动范围的比值比为0.90（95%置信区间，0.85 - 0.95；P < 0.001），表明与腰痛存在显著关联。
非优势腿髋关节内旋活动范围和身高是高中男子软式网球精英运动员腰痛的关键相关因素。
