| 摘 要： | 目的:对比跆拳道运动员静息状态和模拟第二回合比赛一分钟后的静态姿势摆动频谱、稳定性及体重分配,分析影响第三回合比赛平衡能力的风险因素。方法:选择山东省男子跆拳道运动员12名,采用Tetrax平衡测试系统测试受试者静息状态和模拟第二回合比赛一分钟后睁眼自然站立状态(NO)、闭眼自然站立状态(NC)、睁眼站在6cm软垫(PO)、闭眼站在6cm软垫(PC)下的姿势摆动频谱、稳定性指数(ST)和体重分配指数(WDI)。结果:模拟第二回合比赛一分钟后运动员的ST值显著高于静息状态的ST值(P=0.047)。NO姿势摆动频谱分析,静息状态和模拟第二回合比赛一分钟后,跆拳道运动员姿势摆动从F1到F8呈递减趋势,在F3频段模拟第二回合比赛一分钟后运动员摆动强度显著高于静息状态(P=0.036)。体重分配分析模拟第二回合比赛一分钟后NO、NC、PO、PC的WDI值显著(P<0.05)或极显著(P<0.01)高于静息状态。结论:跆拳道运动员正常姿势维持表现为高强度低频率的姿势摆动特点,模拟第二回合比赛一分钟后运动员存在因外周前庭功能异常引起的稳定性下降,体重分布从不同程度上都出现异常。

| Abstract: | Objective:To explore the static postural stability,sway spectrum and weight distribution of taekwondo athletes resting state and the simulation of the second round after one minute,and to analyze the risk factors of the third round postural balance.Methods:Posturography(IBS;Sunlight,Ramat Gan,Israel)was recorded from 12 male taekwondo athletes,members of the Shandong Province Taekwondo.The parameters were stability,sway spectrum and weight distribution for positions with eyes open,eyes closed,eyes open on the foam platform,eyes closed on the foam platform.Results:ST values after the second round a minute later were significantly higher than when they were at rest(P= 0.047).The resting state and the second round a minute later,for eyes open position postural sway from F1 to F8 showed a decreasing trend.The second round a minute later exhibited significantly higher values of F3(P= 0.036),than resting.The WDI values after the second round one minute later were significantly(P<0.05)or highly significantly(P<0.01)higher than the resting state for positions with eyes open,eyes closed,eyes open on the foam platform,eyes closed on the foam platform.Conclusions:To maintain normal position,taekwondo athletes show the high-strength low-frequency swing performance.Peripheral vestibular function abnormalities make athletes less stable at the second round one minute later.At the second round one minute later,athletes show abnormal weight distribution. |
