等速训练对舞者膝关节损伤后肌力与功能康复的影响*任妍静(北京舞蹈学院人文学院，北京100081)【内容提要】文章主要探讨等速训练对舞者膝关节损伤后肌力和功能康复的影响。研究方法为将12名膝关节损伤的专业舞者随机分为实验组和对照组，每组6名。首先，运用德国D＆Ｒ公司开发的Isomed2000等速肌力测试训练系统和Lysholm膝关节评分主观量表对舞者膝关节肌力和损伤状况进行评测。随后实验组进行等速肌力康复训练，对照组进行传统肌力康复训练，训练8周后再次测试对比两组膝关节屈伸肌肌力及Lysholm膝关节评分的变化。研究结果显示，经过康复训练后两组膝关节屈伸肌肌力和Lysholm膝关节评分均有所提高，但等速肌力训练比传统肌力训练效果更为明显。实验组在屈伸肌峰力矩(P＜0.05)、屈肌总做功(P＜0.01)、伸肌总做功(P＜0.05)和Lysholm膝关节评分(P＜0.01)三项指标上提高幅度均高于对照组。研究得出结论，等速肌力康复训练能够有效提高舞者膝关节周围肌肉力量，且训练效果优于传统肌力康复训练，具有维持舞者膝关节稳定性、促进膝关节功能恢复的作用。【关键词】等速训练;膝关节;舞者;损伤康复【中图分类号】J70－05【文献标识码】A【文章编号】1008-2018(2022)06-0157-08MuscleStrengthandFunctionＲehabilitationofDancersafterKneeJointInjurybyIsokineticTrainingＲENYan-jing(SchoolofLiberalArts，BeijingDanceAcademy，Beijing100081，China)Abstract:Thisstudymainlydiscussestheeffectofisokinetictrainingontherehabilitationofmusclestrengthandfunctionofdancersafterkneejointinjury．Twelveprofessionaldancerswithkneejointinjurieswererandomlydividedintoanexperimentalgroupandacontrolgroup，with6dancersineachgroup．First，theIsomed2000isokineticmusclestrengthtestingandtrainingsystemdevelopedbytheGermanD＆ＲcompanyandtheLysholmkneejointscoresubjectivescalewereusedtoevaluatethekneemusclestrengthandinjuryconditionofthedancers．Thentheexperimentalgroupreceivedisokineticstrengthrehabilitationtraining，whilethecontrolgroupreceivedtraditionaltraining．After8weeksoftraining，thechangesinkneeflexorandextensormusclestrengthandLysholmscoresofkneefunctionofthetwogroupswerecompared．Theresultsshowedthatafterrehabilitationtraining，thekneeflexorandextensormusclestrengthandLysholmkneejoint...
