【摘要】：現(xiàn)代生活中,人們對生活質(zhì)量各方面的要求逐漸提高,包括居住環(huán)境、飲食健康化和身體素質(zhì)等等。其中身體素質(zhì)的提升使得康復(fù)及身體機(jī)能增強(qiáng)訓(xùn)練越來越多的引起腦卒中患者、下腰痛患者、運(yùn)動員以及健康人群的關(guān)注。而康復(fù)訓(xùn)練尤其是核心穩(wěn)定訓(xùn)練能夠?qū)φ麄�(gè)身體的肌肉起到鍛煉康復(fù)的作用,因此吸引越來越多學(xué)者對其進(jìn)行研究。現(xiàn)階段利用表面肌電信號分析核心穩(wěn)定訓(xùn)練對人體肌肉影響效果的應(yīng)用已經(jīng)非常廣泛。本文就采用表面肌電信號研究靜態(tài)和動態(tài)核心穩(wěn)定訓(xùn)練動作對人體肌肉的影響。具體研究內(nèi)容如下:第一,測量30名受試者完成6種靜態(tài)核心穩(wěn)定訓(xùn)練動作時(shí)的表面肌電信號,通過提取頻域特征值—中位頻率及其斜率值表征肌肉的疲勞狀態(tài)。結(jié)果顯示,在完成靜態(tài)核心穩(wěn)定訓(xùn)練動作過程中,平板支撐動作引起腹部肌肉和下肢肌肉疲勞度較大;仰臥雙橋和仰臥單橋能引起豎脊肌更大的疲勞;兩點(diǎn)交叉支撐動作雖然沒有引起肌肉較大的疲勞,但是可以訓(xùn)練大部分的肌肉。在6種靜態(tài)核心穩(wěn)定訓(xùn)練動作中,所測肌肉左、右側(cè)疲勞度差異無統(tǒng)計(jì)學(xué)意義(P0.05)。本研究所得結(jié)論,為靜態(tài)核心穩(wěn)定訓(xùn)練動作針對不同肌肉塊的訓(xùn)練效果提供了量化指導(dǎo)。第二,針對在靜態(tài)核心穩(wěn)定訓(xùn)練動作中,有些肌肉塊沒有顯現(xiàn)出疲勞的狀況,本研究又采用時(shí)頻分析方法中的維格納分布方法提取時(shí)頻特征值—瞬時(shí)中值頻率對表面肌電信號進(jìn)行特征提取,并對部分靜態(tài)核心穩(wěn)定訓(xùn)練動作中的表面肌電信號進(jìn)行分析,發(fā)現(xiàn)原來沒有表現(xiàn)疲勞的肌肉現(xiàn)在出現(xiàn)疲勞,即驗(yàn)證此方法的有效性,之后運(yùn)用此方法對動態(tài)核心穩(wěn)定訓(xùn)練動作中的表面肌電信號進(jìn)行特征值提取及分析。第三,日常的訓(xùn)練中,人們都是按照某一頻率連續(xù)不斷地進(jìn)行訓(xùn)練的,所以動態(tài)核心穩(wěn)定訓(xùn)練更符合實(shí)際。本文在靜態(tài)核心穩(wěn)定訓(xùn)練對肌肉康復(fù)效果的基礎(chǔ)上對動態(tài)核心穩(wěn)定訓(xùn)練進(jìn)行研究,采集30名受試者做6種動態(tài)核心穩(wěn)定訓(xùn)練動作的表面肌電信號,通過時(shí)頻特征值—瞬時(shí)中值頻率及其斜率值對肌肉疲勞度進(jìn)行提取與分析。最終得到不同動態(tài)核心穩(wěn)定訓(xùn)練動作對不同肌肉的康復(fù)效果及其相互之間的差異性。并且與靜態(tài)核心穩(wěn)定訓(xùn)練動作時(shí)的肌肉疲勞度進(jìn)行比較,進(jìn)而為康復(fù)醫(yī)師或者健身教練提供更細(xì)致的指導(dǎo)。以上研究為康復(fù)治療師及教練在采用核心穩(wěn)定訓(xùn)練對患者、運(yùn)動員和健康人進(jìn)行康復(fù)及鍛煉提供了一定的理論依據(jù)和量化指導(dǎo)。
[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.
