研究目的:对长拳、太极拳冲拳动作进行肌电实验,分析长拳、太极拳完成冲拳动作时所调动的肌肉及其iEMG值,得出在研究对象本身无差异情况下,不同拳术冲拳的发力对肌肉的调动情况。研究方法:在肌电实验中,以固定个体为研究对象,通过运用美国Noraxon生产的T6无线导遥测肌电对练习长拳、太极拳冲拳时的上下肢肌肉表面肌电特征进行分析。研究结果:长拳冲拳过程中,肌肉活动顺序为腹直肌、三角肌前束、股内侧肌、股直肌、腹外斜肌、股外侧肌、股四头肌、肱三头肌、肱桡肌、竖脊肌;积分肌电显示在长拳冲拳阶段三角肌前束、肱桡肌的积分肌电最高;在整个长拳冲拳过程中,腹外斜肌的肌肉贡献率最大。太极拳冲拳过程中,肌肉活动顺序为肱桡肌、腹外斜肌、股内侧肌、竖脊肌、三角肌前束、腹直肌、股外侧肌、肱三头肌、腹直肌、股四头肌;积分肌电显示在太极拳冲拳阶段肱桡肌、股内侧肌的积分肌电最高;在整个太极拳冲拳过程中,腹内斜肌的机头贡献率最大。研究结论:长拳冲拳过程中,受试者较好完成技术动作,腹直肌首先放电,肌肉力量的发放大部分来源于肱桡肌、三角肌前束和肱三头肌,集中于上肢腰部和手臂。太极拳冲拳过程中,受试者未能掌握技术动作,肌肉发力顺序不符合太极拳冲拳技术要求。
The purpose of this study: EMG experiments were conducted on Changquan and Taijiquan punches, and the muscles and their iEMG values were analyzed when Changquan and Taijiquan completed the Chongquan exercise. The results showed that under the condition of no difference in the subjects themselves, Punch force of muscle mobilization. Methods: In the EMG experiment, the immobilized individuals were selected as the study objects. The electromyographic characteristics of upper and lower extremity muscles were analyzed by using the T6 wireless telemetry EMG produced by Noraxon in the United States. Results: In the process of Changquan punching, the order of muscle activity is rectus abdominis, deltoid, medialis, rectus, lateralis, lateralis, quadriceps, triceps, Brachioradialis muscle, erector spinae; Integral EMG showed that in the Changquan punching stage deltoid anterior bundle, brachioradialis muscle EMG highest score; in the Changquan punching process, the largest contribution to the abdominal muscle obliques . In the process of tai chi punching, the order of muscle activity is brachioradialis, abdominal oblique, intramuscular, erector spinae, deltoid, rectus abdominis, lateral femoris, triceps, rectus abdominis, Quadriceps; integral EMG showed that in the stage of Taijiquan punching, brachioradialis muscle and medialis muscle had the highest electromyogram; in the whole process of Taijiquan punching, the head of abdominal oblique muscle had the largest contribution rate. Conclusions: In the process of Changquan punching, the subjects completed the technique better, and the rectus abdominis first discharged. Most of the muscle strength came from the brachioradialis, anterior deltoid and triceps, focusing on the upper extremities Waist and arm. During the process of Taijiquan punching, the subjects failed to grasp the technical movements, and the order of muscular strength did not meet the technical requirements of Taijiquan punching.
