Abstract

ABSTRACT Purpose: Establishing sex-specific musculoskeletal characteristics promotes specific and effective injury prevention. The purpose was to identify sex differences in musculoskeletal characteristics in soccer athletes.Methods: 80 collegiate male and female soccer athletes participated. Flexibility included: weight-bearing ankle dorsiflexion mobility (DFM), active ankle dorsiflexion (ADF), active knee extension (AKE), and passive hip flexion (PHF). Strength tests included: ankle dorsiflexion/inversion/eversion, knee flexion/extension, hip abduction/adduction/internal/external rotation. LE dynamic postural stability (DPS) was assessed with an accelerometer. DPS was expressed as the Dynamic Postural Stability Index composite (DPSIC) and component scores in the anterior/posterior (APSI), medial/lateral (MLSI), and vertical (VSI) directions. If normally distributed, differences were calculated using a Student’s T-test; if non-normal, a Mann–Whitney U test was utilized.Results: Flexibility tests yielded significant differences for AKE (Dominant:p = 0.008, Non-Dominant:p = 0.040) and PHF (Dominant:p < 0.000,Non-Dominant:p = 0.001). Strength tests yielded significant differences for non-dominant hip internal rotation (p = 0.002). Dynamic postural stability tests yielded significant differences for DPSIC (p = 0.0160) and APSI (p = 0.014).Conclusion: These results implicate that flexibility and DPS may be better linked to sex than strength, suggesting that they may sex-specific musculoskeletal characteristics for the purpose of effective injury prevention.

校际足球运动员下肢肌肉骨骼和神经肌肉特征的性别差异
摘要目的:确定特定性别的肌肉骨骼特征有助于具体有效的损伤预防。目的是确定足球运动员肌肉骨骼特征的性别差异。方法:80名大学生男女足球运动员参加。灵活性包括:负重踝关节背屈活动(DFM)、主动踝关节背屈肌(ADF)、主动膝关节伸展(AKE)和被动髋关节屈曲(PHF)。力量测试包括:踝关节背屈/内翻/外翻、膝关节屈曲/伸展、髋关节外展/内收/内旋/外旋。用加速度计评估LE的动态姿势稳定性(DPS)。DPS表示为动态姿势稳定性指数复合物(DPSIC)和前/后(APSI)、内侧/外侧(MLSI)和垂直(VSI)方向的分量分数。如果正态分布,则使用Student的T检验来计算差异;如果不正常,则使用Mann-Whitney U检验。结果:柔韧性测试的AKE(显性:p=0.008,非显性:p=0.040)和PHF(显性:p<0.000,非显性的:p=0.001)有显著差异。力量测试的非显性髋关节内旋有显著差异(p=0.002)。动态姿势稳定性测试的DPSIC(p=0.0160)和APSI(p=0.01 4)有显著差别。结论:这些结果暗示灵活性和DPS可能比力量更能与性别联系在一起,这表明为了有效预防损伤,它们可能具有特定于性别的肌肉骨骼特征。
