Abstract

Background: Lower limb asymmetry is a critical factor influencing performance and injury risk in football players. Despite the increasing popularity of women's football, limited research has examined how asymmetry varies across different age categories. This study aimed to investigate countermovement jump (CMJ) and horizontal jump (HJ) asymmetry in female football players across four age categories (U14, U16, U18, and +18). Methods: Seventy-six female football players from the same club participated in the study. Players performed unilateral CMJ and HJ tests to assess inter-limb asymmetry. A one-way ANOVA and Chi-square tests were conducted to examine age-related differences in asymmetry levels. Results: CMJ asymmetry significantly varied across age groups (p < 0.001), with the highest asymmetry observed in U14 and the lowest in +18. In contrast, HJ asymmetry remained consistently low across all age groups (p = 0.113). No significant correlation was found between CMJ and HJ asymmetry. Additionally, asymmetry levels in CMJ were significantly associated with age (p = 0.003), whereas no such association was observed for HJ. Conclusions: CMJ asymmetry is more prevalent in younger female football players and tends to decrease with age, suggesting that neuromuscular development plays a role in reducing asymmetry over time. These findings highlight the importance of monitoring asymmetry levels across different age groups to optimize training interventions and injury prevention strategies.

女足球运动员逆向运动和水平跳跃不对称的年龄差异研究。
背景:下肢不对称是影响足球运动员运动表现和损伤风险的关键因素。尽管女子足球越来越受欢迎,但有限的研究调查了不同年龄段的不对称性是如何变化的。本研究旨在探讨4个年龄组(U14、U16、U18和+18)女足运动员的反动作跳(CMJ)和水平跳(HJ)不对称性。方法:76名来自同一俱乐部的女子足球运动员参与了研究。运动员进行单侧CMJ和HJ测试来评估肢间不对称性。采用单因素方差分析和卡方检验检验不对称水平的年龄相关差异。结果:CMJ不对称性在不同年龄组间差异显著(p < 0.001), U14岁时不对称性最高,+18岁时最低。相反,HJ不对称性在所有年龄组中都保持较低水平(p = 0.113)。CMJ与HJ不对称无显著相关。此外,CMJ的不对称水平与年龄显著相关(p = 0.003),而HJ没有观察到这种关联。结论:CMJ不对称在年轻女子足球运动员中更为普遍,并随着年龄的增长而减少,这表明神经肌肉的发育在减少不对称方面发挥了作用。这些发现强调了监测不同年龄组不对称水平的重要性,以优化训练干预和伤害预防策略。
