【摘要】：研究目的:为更好的对比研究散打鞭腿和泰拳扫腿的动作结构特征以及优秀运动员的反应能力及其影响因素,充分了解泰拳横扫腿的技术动作机制,取其优势之法丰富散打鞭腿训练方案。研究方法:用CASIO-EXFH25高速摄像机、表面肌电测试仪采集3名优秀散打运动员鞭腿和三名职业泰拳运动员鞭腿技术动作的相关原始数据,使用ASAS图像解析系统分析系统、肌电分析系统同步分析。研究结果:1泰拳横扫腿与散打鞭腿动作时间、收腿时间均值分别为0.83±0.04;0.95±0.05,0.69±0.08;0.64±0.04。2泰拳与散打运动员髋、膝、踝关节合速度峰值分别为4.14±0.98;3.57±1.05,7.19±1.26;6.21±1.18,12.12±1.95、10.73±2.18。3中泰两国运动员右肩、右髋沿Y轴转动的角度和左脚沿X轴转动角度分别为73.89±7.12°、54.17±6.51°、22.02±3.81°;91.23±8.56°、79.47±6.88°、39.46±4.98°。4中国散打运动员鞭腿技术的目标靶物在X、Y、Z三个方向位移量分别为7.75±0.83cm、38.84±4.67cm、26.32±2.71cm,泰拳运动员位移量分别为12.98±2.18cm、47.32±5.22cm、34.18±3.92cm。5中泰两国运动员的第一次反应时间(TRT),前反应时(PMT),动作时(EDM)的均值分别为910±83ms、690±73ms,637±68ms、483±51ms,273±29ms、207±22ms,第二次反应时间(TRT),前反应时(PMT),动作时(EDM)的均值分别为730±69ms、610±59ms,471±49ms、408±41ms,259±27ms、202±19ms。研究结论:1泰拳横扫腿是鞭打腿与腰腹部肌肉首先动员,而后支撑腿肌肉动员,腰腹部肌肉二次爆发式发力,在触靶时刻,泰拳横扫腿动作有右侧股直肌、股二头肌、腹直肌有明显持续发力。散打选手首先动员的是支撑腿的肌肉通过蹬地与提膝获得较高的髋膝速度。2相较于散打鞭腿,泰拳横扫腿动作的整体时间更长,鞭打时刻末端环节速度更大,髋关节制动更加合理,鞭打阶段支撑腿的膝关节角度大,支撑腿用力程度高。整个动作过程泰拳运动员的躯干扭转幅度更大,延长主动肌工作距离,提高肌肉弹性势能。泰拳运动员横扫腿技术动作的打击效果要优于散打运动员的鞭腿技术动作。3泰拳选手在中枢神经系统的机能还是肌肉调动能力上都更优秀。适宜负荷条件下同组别的运动员前后两次测试的反应时呈下降趋势,适宜负荷条件下EDM呈现一定的稳定性,而PMT下降趋势明显。
[Abstract]:Objective: in order to better compare and study the action structure characteristics and the reaction ability of the outstanding athletes, we can fully understand the technical action mechanism of the cross sweep leg of Thai boxing, and study the characteristics of the action structure of the leash leg and the Thai boxing sweep leg better, and fully understand the technical action mechanism of the Thai boxing cross sweep leg. Take advantage of the method to enrich the training scheme. Methods: using CASIO-EXFH25 high speed camera and surface electromyography tester to collect the original data of the whiplash technique of three outstanding Sanda athletes and three professional Thai boxing athletes, and using the ASAS image analysis system. Synchronous analysis of EMG analysis system. The results were as follows: (1) the mean time of leg retraction was 0.83 卤0.04 (0.95 卤0.05) and 0.69 卤0.08 (0.69 卤0.08) respectively; The peak velocities of hip, knee and ankle joint of 0.64 卤0.04.2 Thai boxing and Sanda athletes were 4.14 卤0.983.57 卤1.05V 7.19 卤1.26, respectively. 6.21 卤1.18 卤12.12 卤1.95 卤10.73 卤2.18.3 right shoulder, right hip rotation angle along Y axis and left foot rotation angle along X axis were 73.89 卤7.12 掳, 54.17 卤6.51 掳, 22.02 卤3.81 掳, respectively. 91.23 卤8.56 掳, 79.47 卤6.88 掳, 39.46 卤4.98 掳. 4 the displacement of target in the three directions of Chinese Sanda athletes' whip leg technique was 7.75 卤0.83 cm ~ (-1) 卤4.67 cm ~ (-1) (26.32 卤2.71 cm), respectively. The average displacement of Thai boxing athletes was 12.98 卤2.18 cm ~ (-1) 47.32 卤5.22 cm ~ (-1) and 34.18 卤3.92cm.5 respectively. The mean value of (EDM) during the first reaction time before (TRT), reaction was 910 卤83 Ms ~ (690 卤73) Ms ~ (63) Ms ~ (637 卤68) Ms ~ (-1) (EDM), respectively, in the first reaction time of Chinese and Thai athletes, and the mean value of (EDM) was 47.32 卤5.22 cm ~ (-1), respectively. The mean values of (EDM) during (PMT), action during the second reaction time before (TRT), were 730 卤69ms, 610 卤59ms, 471 卤49ms, 408 卤41ms, 259 卤27ms, 202 卤19ms, respectively. Conclusion: 1 the cross sweep leg of Thai boxing is the first mobilization of whipping leg and waist abdominal muscle, then the mobilization of supporting leg muscle, the second explosive force of waist and abdomen muscle, and the right rectus femoris muscle and biceps femoris muscle in the time of touching the target. The rectus abdominis has obvious sustained strength. The first thing Sanda players mobilize is that the muscles that support their legs gain higher hip and knee speeds by pedaling and lifting their knees. 2 compared with the lashes, the overall time of the Thai boxing sweeping leg is longer, and the speed of the end link of the whipping moment is higher. The hip joint brake is more reasonable, the knee joint angle of supporting leg is large and the strength of supporting leg is high. The torsion amplitude of the trunk of Thai boxing athletes is larger, the working distance of active muscles is prolonged, and the elastic potential energy of muscles is improved. The stroke effect of Thai boxing athletes is better than that of Sanshou athletes. 3 the ability of central nervous system and muscle movement of Thai boxing athletes is better than that of Sanshou athletes. Under the suitable load condition, the reaction time of the other athletes in the same group showed a downward trend before and after two tests, the EDM showed a certain stability under the suitable load condition, but the PMT decreased obviously.
