【摘要】：标准舞架型相对固定,它关联着舞蹈过程的稳定性,是影响运动成绩的重要因素。该研究采用了文献资料法、专家访谈法、测量法、问卷调查法、实验法与数理统计法研究,对影响男士标准舞架型的主要肌肉及其表面肌电特征进行分析,进而根据专家访谈、问卷调查与实际观测的结果,进一步讨论标准架型的训练方法,为综合分析与正确改进男选手的架型提供科学的理论依据,也为丰富我国体育舞蹈科学研究方法提供可行性的参考材料。标准舞中探戈舞架型特殊,该文只研究具有相对一致的华尔兹、维也纳华尔兹、狐步与快步舞的静态情况下的架型。主要研究结果如下:1.对比测量国内外两名优秀男选手两臂屈肘的标准角度,结果表明,左臂屈肘大约在116°-134°左右,右臂屈肘角度大约在100°-105°左右。在这个区间范围内,水平越高的选手其屈肘角度相对较小。无论处于何种角度,都应保持手臂线条的空间开阔与肩带的松弛。2.从力学角度来讲,男士标准舞架型属于一种静态平衡,在不负重的情况下保持固定姿势,肌肉做等长收缩。从解剖学的角度来讲,男士标准舞架型的动作结构在人体解剖结构中为两臂侧平屈,表现为手肘的内旋及肩部的外展。3.测试结果表明,标准的架型动作,其肌电活动开始的顺序为:三角肌→斜方肌→背阔肌→肱三头肌→肱二头肌→胸大肌→胸锁乳突肌;三角肌、斜方肌、背阔肌最为主要;结束顺序为:胸锁乳突肌→肱二头肌→肱三头肌→胸大肌→斜方肌→背阔肌→三角肌,胸锁乳突肌最先结束放电,三角肌最后结束放电;持续时间长短顺序为:三角肌→肱三头肌→背阔肌→斜方肌→胸大肌→肱二头肌→胸锁乳突肌,三角肌的肌电活动持续时间最长;用力大小情况为三角肌用力最大,背阔肌次之,其次分别为肱三头肌和斜方肌,胸锁乳突肌最小。可见,三角肌、背阔肌、肱三头肌和斜方肌是最主要的肌肉。4.以表面肌电实验为参考,结合问卷调查与实际观测的结果和各专家的建议,对男士标准舞架型的训练方法从一般力量训练和专项力量训练两个方面进行初步讨论,以供选手和教练员在训练中作可行性的参考。
[Abstract]:The standard dance frame is relatively fixed, which is related to the stability of the dance process and is an important factor affecting the performance of sports. This study adopts the methods of literature, expert interview, measurement, questionnaire, experiment and mathematical statistics. Based on the analysis of the main muscles and their surface electromyoelectric characteristics, the training methods of the standard frame type are further discussed according to the results of expert interviews, questionnaire surveys and actual observations. It provides a scientific theoretical basis for comprehensive analysis and correct improvement of the frame type of male contestants, and also provides a feasible reference material for enriching the scientific research methods of sports dance in China. This paper only studies the static frame of waltz, Viennese waltz, foxtrot and trot. The main results are as follows: 1.Contrastive measurement of the standard angle of elbow flexion of two excellent male contestants at home and abroad, the results show that, The elbow flexion of the left arm is about 116 掳-134 掳, and the angle of elbow flexion of the right arm is about 100 掳-105 掳. Both should maintain the open space of the arm line and the relaxation of the shoulder straps. 2. From a mechanical point of view, the men's standard dance frame is a kind of static balance, holding a fixed posture without carrying a load, and the muscles do equal length contractions. From an anatomical point of view, In the human anatomical structure, the movement structure of the men's standard dance frame is the lateral flexion of both arms, which is represented by the internal rotation of the elbow and the abduction of the shoulder. 3. The test results show that the standard frame movement starts in the order of the deltoid muscle. 鈫扵rapezius muscle. 鈫扡atissimus dorsi muscle. 鈫扵riceps brachii muscle. 鈫払iceps brachii muscle. 鈫扨ectoralis major muscle. 鈫扴ternocleidomastoid muscle, deltoid muscle, trapezius muscle and latissimus dorsi muscle are the most important. 鈫払iceps brachii muscle. 鈫扵riceps brachii muscle. 鈫扨ectoralis major muscle. 鈫扵rapezius muscle. 鈫扡atissimus dorsi muscle. 鈫扗eltoid muscle, sternocleidomastoid muscle discharges first, deltoid muscle end discharge; duration: deltoid muscle. 鈫扵riceps brachii muscle. 鈫扡atissimus dorsi muscle. 鈫扵rapezius muscle. 鈫扨ectoralis major muscle. 鈫払iceps brachii muscle. 鈫扞n sternocleidomastoid muscle, deltoid muscle had the longest electromyographic activity, deltoid muscle had the largest force, latissimus dorsi muscle was the second, triceps brachii muscle and trapezius muscle were the second, and sternocleidomastoid muscle was the smallest. Triceps brachii muscle and trapezius muscle are the most important muscles. This paper discusses the training method of men's standard dance frame from two aspects of general strength training and special strength training for the reference of contestants and coaches in training.
