摘要

目的:本研究的目的是确定积极训练的综合格斗(MMA)运动员头部运动时视力损失的程度:方法:对 22 名无症状的男性综合格斗(MMA)运动员(年龄 = 29.2 ± 5.1)进行前庭-眼反射功能评估,方法是在偏航和俯仰平面上测量静态视力与动态视力测试之间的差异:结果:静态视力测试的平均对数为-0.173(标准差 [SD] = 0.114)。动态视力测试的平均值随头部运动而下降,偏航时为 0.196 logMAR(标准差 = 0.103);p < 0.001;俯仰时为 0.283 logMAR(标准差 = 0.133);p < 0.001:综合格斗运动员在头部运动时视力下降,超出了正常范围。这些下降可能表明前庭眼反射受损,且与自我报告的脑震荡病史无关。由于没有对照组,因此应谨慎解释这些结果。

Evidence of dynamic visual acuity impairment in asymptomatic mixed martial arts fighters.

Aim: The purpose of this study was to determine the amount of visual acuity loss with head movement in actively training mixed martial arts (MMA) fighters.

Methods: Vestibulo-ocular reflex function of 22 asymptomatic, male MMA fighters (age = 29.2 ± 5.1) was assessed by taking the difference between static visual acuity and the dynamic visual acuity test, in both yaw and pitch planes.

Results: The mean static visual acuity testing logMAR was -0.173 (standard deviation [SD] = 0.114). Mean dynamic visual acuity test values decreased with head movement to 0.196 logMAR (SD = 0.103) in yaw; p < 0.001, and to 0.283 logMAR (SD = 0.133) in pitch; p < 0.001.

Conclusion: MMA fighters had a decay, beyond normal ranges, in visual acuity during head movement. These decreases may suggest vestibulo-ocular reflex impairment and were unrelated to self-reported concussion history. These results should be cautiously interpreted since there was not a control group.
