肌运动

There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn\'t be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes\' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven\'t taken the raising and pulling back the row seriously.

射箭的肢体动作幅度小，简单的手段和分析不能满足其需要，笔者结合各种运动生物力学仪器优点及射箭项目的特性，选用Qualisisy红外光点测试系统、Footscan足底压力测试系统、Noraxon肌电遥测系统等对国家队射箭队运动员进行多方位的测试，运用相关软件及数理统计方法，对运动员的射箭动作技术，从射箭动作的姿态构架、肢体运动特点，身体姿态平衡稳定性、足底压力中心分布、肌电特性等进行全面分析，结论及建议如下：结论：第一，姿态角、肌肉用力激活程度、举弓阶段主要用力肌肉激活顺序、举弓、开弓时间等的一致性可作为射箭技术动作评价指标；第二，各动作阶段所用时间的长短不能作为技术评价指标，但举、开弓的时间相对较固定，开举弓时间比与中国国家队射箭成绩正弱相关达到显著性；第三，闭眼状态下足底压力中心单位面积轨迹长与144支箭最好成绩正相关达到显著性，可作为身体素质、选材及成绩预测的参考依据；实射时身体平衡的足底压力中心指标与成绩的相关程度具有个体性差异、阶段性差异；第四，射箭运动员实射时身体在前后方向上的稳定性较差，这与运动员的站立姿态、腹背肌力量的不匹配以及射箭没有专业运动鞋有关；第五，运动学及肌电学都表明中国射箭训练对举弓、开弓阶段的重视不够，背部肌肉用力特征不明显，撒放技术合理性不高。

This means that glucose transport capacity was not a key determinant for glycogen accumulation under normal diet and the training situation; Ingestion of creatine or glutamine for 2 weeks prior glycogen depletion exercise exert no rule in glucose transport, GN gene expression, GS activity, and muscle glycogen resynthesis rate and amount during recovery from depletion exercise, but the interactions between endurance training and glutamine, high-intensity intermittent training and creatine, and endurance training and high-intensity intermittent training, were all capable of increasing muscle glycogen resynthesis significantly.

说明正常饮食训练情况下，肌肉葡萄糖转运能力不是决定肌糖原储量的关键因素；耗竭运动前补充肌酸或谷氨酰胺，对运动后恢复过程中的肌肉葡萄糖转运、GN基因表达和GS活性无明显影响，对运动后肌糖原再合成的速率和量也无显著效应，但耐力训练与谷氨酰胺、间歇高强度训练与肌酸以及耐力训练与间歇高强度训练的交互作用可使肌糖原合成量显著增加。

Our experiment aim at use the acupuncture method"Wang's Jiaji points"which created by the famous doctor Leting wang from Beijing hospital of TCM at the early days of the stroke patients to prevent and treat hypermyotonia,prevent muscle spasm or lessen the spasm level,to improve the stroke patient's ADL.that study is a prospective , randomized, double-blind,parallel-group,use the random digits table method,and compared with the"twelve points of hands and feet",which used frequently at acupuncture department of Beijing hospital of TCM.we use the NIHSS scale, improved Ashworth scale,domestic Fugl-Meyer scale, castigatory MBI scale to score the patients'muscular tension and motor function improvement condition.

No significant difference were found between left and right hand weight loading for erector spinae during the trunk movements, but the values of AEMG with back weight loading were significantly higher than left and right hand weight loading;(2)The AEMG of lumbar multifidus had no significantly different under three load ways during the walking.

Methods Employing cholera toxin B-subunit combined horseradish peroxidase retrograde tracing technique and cholera toxin B-subunit combined colloid goldretrograde tracing with calcitonin gene-related peptideimmunohistochemical double-labeled staining technique,the innervation of musculus sacrococcygeus ventralis medialisin rats was studied.

大鼠骶尾腹内侧肌又称荐尾腹侧中肌(musculus sacrococcygeus ventralis medialis)或屈尾短肌，是位于盆腔后壁、骶椎前方的一对梭形肌肉，属尾肌群，因其功能似乎仅为屈尾，故至今尚未引起人们的注意，而与该肌位置关系较密切的会阴肌因在某些运动神经元疾患时仍可保持其正常生理功能而一直受到神经工作者的关注，尤其是近年来有诸多文献报道了会阴肌的神经支配、相关神经元的细胞构筑、神经递质和神经调质的分布以及纤维联系特点［1～10］，藉以探讨运动神经元疾病的神经病理学。

Result: In first experiment, the results shows erector spinae of CLBP had positive correlation in the force-sEMG signal relationship on the testing of non-fatigue state of step extensions exercise; AEMG, MPF, IMPF increased with the load, but the Lempel-Ziv Complexity remain firm against the load. The second experiment of the research was that the mean values and the slopes of sEMG of the LBP were significantly different from healthy subjects during the isometric contractions of 20%MVC load intensity, except AEMG.
