We aimed to implement strength and balance training for elite adolescent male soccer players with functional ankle instability (FAI) to assess kinesiophobia, ankle instability, ankle function, and performance. This cluster randomized controlled trial comprised 51 elite adolescent male soccer players with FAI recruited from six different teams, divided into strength, balance, and control groups (SG, n = 17; BG, n = 17; and CG, n = 17, respectively). The SG and BG underwent strength and balance training sessions three times per week for 6 weeks. Primary outcomes were the Tampa scale for kinesiophobia-17 (TSK) and Cumberland ankle instability tool (CAIT) scores to assess kinesiophobia and FAI, respectively. Secondary outcomes were ankle strength (four directions), dynamic balance, static balance (ellipse, displacement, velocity), and performance (figure 8 and side-hop tests). A significant interaction effect was observed for both TSK and CAIT post-intervention (both, < 0.01). In post hoc analyses, the BG had significantly better outcomes in reducing TSK. The SG and BG showed greater improvements in CAIT scores. Regression analysis indicated that CAIT severity correlated significantly with TSK ( = 0.039, = 0.289). For secondary outcomes, the SG and BG were superior in terms of ankle dorsiflexion/inversion strength, static balance displacement, and figure-8 and side-hop tests (all, < 0.05). The BG showed significantly better static balance ellipse results < 0.05). The 6-week intervention significantly enhanced kinesiophobia management, ankle stability, and performance. Balance training effectively mitigated kinesiophobia and improved balance, compared with strength training alone. Even small variations in CAIT severity can influence kinesiophobia, highlighting the potential benefits of balance training. Integrating balance training into training programs can address both physical and psychological aspects of ankle instability. Research is recommended to explore the longitudinal effects of these interventions and their potential to prevent injury recurrence.
我们旨在对患有功能性踝关节不稳（FAI）的精英青少年男性足球运动员进行力量和平衡训练，以评估运动恐惧、踝关节不稳、踝关节功能和运动表现。这项聚类随机对照试验纳入了 51 名来自六支不同球队的患有 FAI 的精英青少年男性足球运动员，他们被分为力量训练组、平衡训练组和对照组（SG 组，n = 17；BG 组，n = 17；CG 组，n = 17）。SG 组和 BG 组每周进行 3 次力量和平衡训练，共进行 6 周。主要结局指标为 Tampa 运动恐惧调查量表 17 项（TSK）和 Cumberland 踝关节不稳工具（CAIT）评分，分别评估运动恐惧和 FAI。次要结局指标为踝关节力量（四个方向）、动态平衡、静态平衡（椭圆、位移、速度）和运动表现（8 字和侧跳测试）。干预后 TSK 和 CAIT 均出现显著的交互效应（均 P < 0.01）。事后分析显示，BG 组在降低 TSK 方面的效果显著更好。SG 组和 BG 组在 CAIT 评分方面的改善更显著。回归分析表明，CAIT 严重程度与 TSK 显著相关（ = 0.039， = 0.289）。在次要结局方面，SG 组和 BG 组在踝关节背屈/内翻力量、静态平衡位移以及 8 字和侧跳测试方面表现更好（均 P < 0.05）。BG 组在静态平衡椭圆测试中的结果显著更好（P < 0.05）。6 周的干预显著改善了运动恐惧管理、踝关节稳定性和运动表现。与单纯的力量训练相比，平衡训练能更有效地减轻运动恐惧并改善平衡。即使 CAIT 严重程度略有变化，也可能会影响运动恐惧，这突显了平衡训练的潜在益处。将平衡训练纳入训练计划中，可以同时解决踝关节不稳的身体和心理方面的问题。建议开展研究，以探讨这些干预措施的长期效果及其预防踝关节再次受伤的潜力。
