耳穴贴压缓解射击运动员视疲劳的研究

Effects of auricular point sticking on asthenopia in shooting athletes

目的探讨耳穴贴压对缓解射击运动员视疲劳的作用。方法选取上海市射击射箭运动中心的24名视疲劳射击运动员,分为治疗组和对照组各12名。所有运动员均于耳穴贴压治疗研究前后进行视疲劳问卷、闪光融合频率、视觉反应时、明视持久度及自觉疲劳分级测试。计量资料用均数±标准差(x±s)表示。采用配对t检验、两独立样本t检验,x^2检验对数据进行数理统计,以P<0.05为差异有统计学意义。结果经过为期2个月的治疗,耳穴贴压缓解射击运动员视疲劳的总有效率为41.67%,治疗组治疗前视疲劳得分为(5.83±2.69),治疗后(4.17±2.33),呈显著降低(t=2.50,P<0.05);治疗前闪光融合频率时间为(22.05±2.80)Hz,治疗后为(25.28±3.31)Hz,延长非常显著(t=-5.42,P<0.01);视觉反应时治疗前为(0.70±0.07)s,治疗后(0.52±0.09)s,呈非常显著降低(t=5.58,P<0.01);明视持久度治疗前(57.97±13.73)%,治疗后(68.65±14.61)%,呈显著增高(t=-2.42,P<0.05);自觉疲劳分级治疗前为(12.75±2.93),治疗后为(10.25±2.63),呈显著降低(t=2.21,P<0.05)。结论耳穴贴压对于缓解射击运动员的视疲劳和精神疲劳具有一定的作用,且两者之间具有相关性。

Objective To investigate the effect of auricular acupressure therapy on visual fatigue in shooting athletes.Methods Twenty-four shooting athletes suffering from visual fatigue from the shanghai shooting and archery sports center were included in this study.All of athletes were divided into two groups,treatment group and control group（n = 12 for each group）.The visual fatigue questionnaire,critical flicker frequency,the visual reaction time,the visuognosis persistence and the subjective fatigue grading were determined before and after treatment in athletes with auricular point sticking.Auricular acupressure therapy was used for athletes in treatment group.Data were analyzed with the paired t test and x^2 test.Mean ±standard deviation（x ± s） was used for measurement of data.P-values less than 0.05 were considered significant.Results The total efficiency rate of visual fatigue in shooting athletes was 41.67%in treatment group after auricular acupressure treatment for two months.The forward-looking fatigue rate was（5.83 ±2.69） before treatment,which was significantly decreased after treatment（4.17± 2.33,t = 2.50;P〈0.05）.The critical flicker frequency was significantly elevated after treatment（25.28 ±3.31） Hz compared with that before treatment（22.05 ±2.80,f =-5.42;P〈0.01）.The visual reaction time was significandy decreased after treatment（0.52 ± 0.09） s than that before treatment（0.70 ± 0.07） s（t = 5.58;P〈0.01）.The visuognosis persistence was（57.97 ± 13.73）%before treatment and（68.65 ± 14.61）%after treatment,showing a significant increase（t =-2.42;P〈0.05）.The subjective fatigue grading was significantly decreased after treatment（10.25 ± 2.63） compared with that before treatment（12.75 ± 2.93,t=2.21;P0.05）.Conclusion Auricular acupressure therapy has a certain effect on reheving visual and mental fatigue in shooting athletes,and possess a correlation between them.
