摘要

在足球运动中,肌肉力量和平衡能力关系到伤病的预防和比赛动作的表现。本研究的目的有两个:(1)检查等速力量和平衡评估中的双边不对称;(2)评估肌肉力量和平衡测量之间的关系。对88名男性青少年足球运动员进行了身体成分(InBody 770)、等速力量(Biodex System 4 Pro Dynamometer)和平衡性能(Biodex balance System)评估。配对样本进行t检验,以确定双方在力量和平衡方面的差异。Pearson相关性和多元线性回归分析评估了力量和平衡之间的关系。在膝关节屈肌(KF)和膝关节伸肌(KE)峰值扭矩(PT)评分中没有观察到显著的双侧强度差异。除了外侧内侧稳定指数外,两组在平衡措施上没有差异,外侧内侧稳定指数在使用首选腿时更好(p≤0.01;D = 0.29)。KE PT与平衡任务有显著相关(p≤0.01)。KF和KE PT在非首选腿和首选腿的总体稳定性指数的共同方差分别为18%至22%。监测双侧不对称的策略对于提高单侧运动(如改变方向和冲刺)的表现以及识别有受伤风险的运动员可能至关重要。在足球训练的早期阶段采用这些策略可能对球员的长期发展至关重要。

Bilateral Asymmetry and the Relationship Between Unilateral Isokinetic Strength and Balance Performance in Male Adolescent Football Players
Muscle strength and balance ability have been related to injury prevention and game actions performance in football. The aims of this study are twofold: (1) to examine bilateral asymmetries in isokinetic strength and balance assessments, and (2) to evaluate the relationship between muscle strength and balance measures. Eighty-eight male adolescent football players were assessed for body composition (InBody 770), isokinetic strength (Biodex System 4 Pro Dynamometer), and balance performance (Biodex Balance System). Paired samples t-tests were conducted to determine bilateral differences in strength and balance. Pearson correlations and multiple linear regression analyses evaluated the relationship between strength and balance. No significant bilateral strength differences were observed in knee flexors (KF) and knee extensors (KE) peak torque (PT) scores. No bilateral differences were found for balance measures, except in the lateromedial stability index, which was better while performing with the preferred leg (p ≤ 0.01; d = 0.29). Significant correlations were found between KE PT and balance tasks (p ≤ 0.01). KF and KE PT shared between 18 and 22% of the common variance in the overall stability index in the non-preferred and preferred leg, respectively. Monitoring strategies of bilateral asymmetries may be crucial to enhance performance in tasks underpinned by unilateral movements, such as changes of direction and sprints, and to identify players at risk of injury. Adopting these strategies during the early stages of football training might be crucial for players’ long-term development.
