Few studies have explored relationships between low back pain (LBP) and physical characteristics (physique, muscle strength, tightness, and flexibility) in female rhythmic gymnasts (RGs).
Due to their extreme flexibility, modifiable physical factors for LBP in RGs are not related to muscle tightness.
Cross-sectional study.
Level 4.
College female RGs (n = 95) were categorized into LBP and non-LBP groups based on questionnaires and orthopaedic surgeon interview. Physical assessments included whole-body bone mineral content and density, trunk lean body mass, and scoliosis presence by dual-energy X-ray absorptiometry scans, presence of abnormal findings and spine alignment by magnetic resonance imaging scans, hip muscle strength testing (flexion, extension, and abduction), range of motion (ROM), and flexibility testing. LBP and non-LBP groups were compared, and multivariate regression analysis performed.
RGs with LBP exhibited significantly longer practice time, lower hip flexion muscle strength on the nondominant side versus dominant side, lower active straight leg raise on the nondominant side versus dominant side, and lower hip external rotation (ER) ROM on the nondominant side versus dominant side. A history of LBP was also associated with current LBP. Multivariate logistic regression analysis revealed that a history of LBP (odds ratio [OR], 6.33; 95% CI, 1.56-25.62), differences in hip flexion strength (OR, 0.96; 95% CI, 1.00-1.08), and differences in hip ER ROM (OR, 1.12; 95% CI, 1.03-1.19) were factors associated with LBP.
LBP was experienced by 27.3% RGs and associated not only with a history of LBP and a deficit in hip flexor strength on the nondominant side but also a deficit in hip ER ROM on the nondominant side.
Focusing on hip flexor strength and hip ER ROM on the nondominant side may be of value for LBP rehabilitation and prevention in RGs.
很少有研究探讨女子艺术体操运动员（RGs）的腰痛（LBP）与身体特征（体格、肌肉力量、紧张度和柔韧性）之间的关系。
由于RGs具有极高的柔韧性，其LBP的可改变身体因素与肌肉紧张度无关。
横断面研究。
4级。
根据问卷和骨科医生访谈，将95名大学女子RGs分为LBP组和非LBP组。身体评估包括通过双能X线吸收法扫描测量全身骨矿物质含量和密度、躯干去脂体重以及脊柱侧弯情况，通过磁共振成像扫描检查异常发现和脊柱排列情况，进行髋部肌肉力量测试（屈曲、伸展和外展）、活动范围（ROM）和柔韧性测试。比较LBP组和非LBP组，并进行多因素回归分析。
患有LBP的RGs练习时间显著更长，非优势侧与优势侧相比髋部屈曲肌肉力量更低，非优势侧与优势侧相比主动直腿抬高更低，非优势侧与优势侧相比髋部外旋（ER）ROM更低。LBP病史也与当前的LBP相关。多因素逻辑回归分析显示，LBP病史（优势比[OR]，6.33；95%可信区间[CI]，1.56 - 25.62）、髋部屈曲力量差异（OR，0.96；95%CI，1.00 - 1.08）以及髋部ER ROM差异（OR，1.12；95%CI，1.03 - 1.19）是与LBP相关的因素。
27.3%的RGs经历过LBP，这不仅与LBP病史以及非优势侧髋部屈肌力量不足有关，还与非优势侧髋部ER ROM不足有关。
关注非优势侧髋部屈肌力量和髋部ER ROM可能对RGs的LBP康复和预防有价值。
