摘　　要：目的:研究应用无创肌肉诊断技术MyotonPRO检测仪对花剑运动员在比赛前后下肢肌肉状态变化进行定量分析,探讨MyotonPRO评估花剑运动员下肢肌肉状态的应用价值。方法:选取参加2021年全国击剑锦标赛的12名(男女各6名)江苏花剑运动员,在个人比赛前后进行下肢肌肉状态测试。结果:比赛后,前腿股外侧肌、股内侧肌的振荡频率、动态硬度显著增强(P<0.05),胫骨前肌和股内侧肌的对数衰减值显著增强(P<0.05);比赛后,后腿股外侧肌和腓肠肌的动态硬度显著提升(P<0.05)。结论:个人比赛后花剑运动员前腿的股外侧肌、股内侧肌及后腿的股内侧肌和腓肠肌肌肉疲劳程度较高,比赛结束后需要着重对其进行拉伸、按摩处理,缓解肌肉疲劳促进机体恢复;Myoton设备简单方便,能够将肌肉状态特性通过相关参数进行量化,准确地反映出肌肉状态。Objective:In this study,the non-invasive muscle diagnostic technology-MyotonPRO detector was used to quantitatively analyze the changes of lower limb muscle status of foil athletes before and after competition,and to explore the application value of MyotonPRO in evaluating the lower limb muscle status of foil athletes.Methods:12 Jiangsu foil athletes participated in the 2021 National Fencing Championships,and the lower limb muscle status was tested before and after individual competitions.Results:After the competition,the oscillation frequency and dynamic stiffness of the vastus lateralis and vastus medialis of the front leg were significantly enhanced(P<0.05),and the logarithmic attenuation values of the tibialis anterior and vastus medialis were significantly enhanced(P<0.05);after the competition,the dynamic stiffness of the hind legs to the vastus lateralis and gastrocnemius was significantly improved(P<0.05).Conclusion:After the individual competition,the vastus lateralis muscle,vastus medialis muscle of the front leg,and the vastus medialis muscle and gastrocnemius muscle of the hind leg of foil athletes have a higher degree of muscle fatigue.After the competition,it is necessary to focus on stretching and massage treatment to relieve muscle fatigue and promote body recovery;The Myoton device is simple and convenient,and can quantify the muscle state characteristics through relevant parameters to accurately reflect the muscle state.
