摘要:

目的 观察功能性踝关节不稳(FAI)对平衡和下肢爆发力的影响。
方法 2024年5月,在哈尔滨体育学院招募经常进行规律且高强度运动的男性FAI者26例,其中双侧(双侧组)和左侧(单侧组)各13例。同时招募13例未发生损伤的男性高强度运动者作为对照组。采用Gaitview足底压力分析系统测量双足睁、闭眼站立时的左脚、右脚和身体重心移动面积,单足睁、闭眼时的摇摆角度、置信椭圆直径最大/最小圆面积比、摇摆比率和置信椭圆;进行Y平衡测试(YBT);采用Opto-jump运动素质光学测评仪测量单脚左/右跳、直立跳和反向跳的腾空时间和重心腾空高度。
结果 左侧单足闭眼站立时,各组间摇摆角度、置信椭圆直径最大/最小圆面积比、摇摆比率和置信椭圆有显著性差异(F > 3.300, P < 0.05),对照组最小(P < 0.05);右侧单足闭眼站立时,各组间摇摆角度、摇摆比率和置信椭圆存在显著性差异(F > 4.404, P < 0.05),对照组小于双侧组(P < 0.05),单侧组摇摆比率和置信椭圆小于双侧组(P < 0.05)。各组间YBT结果有显著性差异(F > 3.649, P < 0.05),双侧组最小(P < 0.05)。各组间反向跳腾空时间和重心腾空高度存在高度显著性差异(F > 7.458, P < 0.01),双侧组最小(P < 0.05)。
结论 FAI影响单足闭眼静态平衡能力、动态平衡能力和下肢爆发力。

Abstract:

Objective To observe the influence of functional ankle instability (FAI) on balance and lower limb explosive power.
Methods A total of 26 male FAI participants, 13 bilateral (bilateral group) and 13 left (left group), who regularly engaged in high-intensity exercise, were recruited at Harbin Sport University in May, 2024. Meanwhile, 13 uninjured male participants who engaged in high-intensity exercise were recruited as control group. They were measured the moving area of the left foot, right foot and body center of gravity standing on feet with the eyes opened and closed; as well as the sway angle, confidence ellipse diameter (maximum and minimum) to circle area ratio, sway ratio and confidence ellipse standing on single foot, with Gaitview plantar pressure analysis system. They were also tested with Y-balance test (YBT), and were measured flight time and center of gravity height during jumps single leg left/right drift, stiffness and counter movement jump using Opto-jump Optical Measurement of Motor Quality.
Results There were significant differences among the groups in swing angle, confidence ellipse diameter (maximum and minimum) to circle area ratio, swing ratio and confidence ellipse as left-leg stance with eyes closed (F > 3.300, P < 0.05), which was the least in the control group (P < 0.05). Swing angle, swing ratio and confidence ellipse were also different among the groups as right-leg stance with eyes closed (F > 4.404, P < 0.05), and they were less in the control group than in the bilateral group (P < 0.05), and less in the left group than in the bilateral group (P < 0.05), except swing angle. There was a significant difference in YBT results (F > 3.649, P < 0.05), which was the least in the bilateral group (P < 0.05). There were significant differences in the flight time and center of gravity height during counter movement jump (F > 7.458, P < 0.01), which was the least in the bilateral group (P < 0.05).
Conclusion FAI may impair the static balance as single-leg stance with eyes closed, dynamic balance and lower limb explosive power.

Key words: functional ankle instability, balance, lower limb explosive power
