【摘要】：现代生活中,人们对生活质量各方面的要求逐渐提高,包括居住环境、饮食健康化和身体素质等等。其中身体素质的提升使得康复及身体机能增强训练越来越多的引起脑卒中患者、下腰痛患者、运动员以及健康人群的关注。而康复训练尤其是核心稳定训练能够对整个身体的肌肉起到锻炼康复的作用,因此吸引越来越多学者对其进行研究。现阶段利用表面肌电信号分析核心稳定训练对人体肌肉影响效果的应用已经非常广泛。本文就采用表面肌电信号研究静态和动态核心稳定训练动作对人体肌肉的影响。具体研究内容如下:第一,测量30名受试者完成6种静态核心稳定训练动作时的表面肌电信号,通过提取频域特征值—中位频率及其斜率值表征肌肉的疲劳状态。结果显示,在完成静态核心稳定训练动作过程中,平板支撑动作引起腹部肌肉和下肢肌肉疲劳度较大;仰卧双桥和仰卧单桥能引起竖脊肌更大的疲劳;两点交叉支撑动作虽然没有引起肌肉较大的疲劳,但是可以训练大部分的肌肉。在6种静态核心稳定训练动作中,所测肌肉左、右侧疲劳度差异无统计学意义(P0.05)。本研究所得结论,为静态核心稳定训练动作针对不同肌肉块的训练效果提供了量化指导。第二,针对在静态核心稳定训练动作中,有些肌肉块没有显现出疲劳的状况,本研究又采用时频分析方法中的维格纳分布方法提取时频特征值—瞬时中值频率对表面肌电信号进行特征提取,并对部分静态核心稳定训练动作中的表面肌电信号进行分析,发现原来没有表现疲劳的肌肉现在出现疲劳,即验证此方法的有效性,之后运用此方法对动态核心稳定训练动作中的表面肌电信号进行特征值提取及分析。第三,日常的训练中,人们都是按照某一频率连续不断地进行训练的,所以动态核心稳定训练更符合实际。本文在静态核心稳定训练对肌肉康复效果的基础上对动态核心稳定训练进行研究,采集30名受试者做6种动态核心稳定训练动作的表面肌电信号,通过时频特征值—瞬时中值频率及其斜率值对肌肉疲劳度进行提取与分析。最终得到不同动态核心稳定训练动作对不同肌肉的康复效果及其相互之间的差异性。并且与静态核心稳定训练动作时的肌肉疲劳度进行比较,进而为康复医师或者健身教练提供更细致的指导。以上研究为康复治疗师及教练在采用核心稳定训练对患者、运动员和健康人进行康复及锻炼提供了一定的理论依据和量化指导。
[Abstract]:In modern life, people's demands on all aspects of quality of life, including living environment, healthy diet and physical fitness, etc. Among them, the improvement of physical fitness makes rehabilitation and body function enhancement training more and more attention of stroke patients, low back pain patients, athletes and healthy people. Rehabilitation training, especially core stability training, can exercise the whole body muscles, so more and more scholars study it. At present, it is widely used to analyze the effect of core stabilization training on human muscle by surface electromyography (EMG). In this paper, the influence of static and dynamic core stabilization training on human muscle is studied by surface electromyography. The main contents are as follows: first, the surface electromyography (EMG) signals of 30 subjects were measured when they completed 6 static core stable training exercises. The frequency domain eigenvalues, median frequencies and their slope values were extracted to characterize the fatigue state of the muscles. The results showed that the fatigue of abdominal and lower extremity muscles was caused by plate support in the process of static core steady training, and the fatigue of erector spinal muscle was caused by supine double bridge and supine single bridge. Two-point cross-support does not cause muscle fatigue, but can train most muscles. There was no significant difference in fatigue between left and right muscles in 6 static core training exercises (P 0.05). The conclusion of this study provides quantitative guidance for the training effect of static core steady training for different muscle masses. Second, in the case of static core steady training, some muscle blocks do not show fatigue. In this study, the time frequency eigenvalue and instantaneous median frequency are extracted by Wigner distribution method, and the surface EMG signals in some static core stable training actions are analyzed. It is found that the muscles that did not show fatigue now appear fatigue, that is, to verify the effectiveness of this method, and then use this method to extract and analyze the eigenvalues of surface EMG signals in dynamic core stabilization training. Thirdly, in daily training, people train continuously according to a certain frequency, so dynamic core stability training is more practical. On the basis of the effect of static core stabilization training on muscle rehabilitation, the dynamic core stabilization training was studied in this paper. The surface electromyography (EMG) signals of 6 kinds of dynamic core stabilization exercises were collected from 30 subjects. Muscle fatigue was extracted and analyzed by time-frequency eigenvalue, instantaneous median frequency and slope. Finally, the rehabilitation effects of different dynamic core stable training actions on different muscles and their differences are obtained. And compared with the static core steady training muscle fatigue, and then provided more detailed guidance for the rehabilitation physician or fitness coach. The above research provides certain theoretical basis and quantitative guidance for rehabilitation and exercise of patients, athletes and healthy people by using core stable training for rehabilitation therapists and coaches.
