【摘要】：為探究水阻劃船器拉槳階段身體各環(huán)節(jié)的運(yùn)動特征,通過運(yùn)動捕捉分析水阻劃船器拉槳階段的運(yùn)動學(xué)特征和肌肉用力特征。本文選取6名男子青少年賽艇運(yùn)動員和6名普通專業(yè)大學(xué)生為實(shí)驗(yàn)對象,過對男子青少年賽艇運(yùn)動員和普通運(yùn)動員在水阻劃船器拉槳技術(shù)動作進(jìn)行三維視角下的模擬劃船分析,采用三維運(yùn)動捕獲系統(tǒng)和表面肌肌電系統(tǒng)同步分析方法,采集賽艇拉槳技術(shù)動作身體各環(huán)節(jié)的運(yùn)動學(xué)參數(shù)和原始肌電圖。分析和討論水阻劃船器運(yùn)動時(shí)的指標(biāo)與運(yùn)動姿態(tài)和肌肉用力的影響,再結(jié)合風(fēng)阻劃船器在專業(yè)訓(xùn)練中的情況,對比不同組別之間的特征差異。研究表明,在阻力特征方面,由關(guān)節(jié)角速度的結(jié)果間接驗(yàn)證了水阻劃船器的拉槳是從迅速蹬腿到上肢用力后到肋骨前,整個(gè)拉槳周期都是維持一種阻力不變這一特點(diǎn),與風(fēng)阻劃船器持續(xù)不斷平穩(wěn)加大的阻力特點(diǎn)有差別;在運(yùn)動學(xué)特征方面,角度活動范圍在專業(yè)組和普通組的所有關(guān)節(jié)都未發(fā)現(xiàn)顯著性差異(p0.05);角速度峰值在專業(yè)組的腕關(guān)節(jié)和膝關(guān)節(jié)存在顯著性差異(p0.05),角速度峰值在普通組的所有關(guān)節(jié)均不存在顯著性差異(p0.05);在表面肌電特征方面,在拉槳過程中,專業(yè)組身體各環(huán)節(jié)肌肉發(fā)力依次表現(xiàn)為股四頭肌、豎脊肌、肱二頭肌、三角肌、背闊肌、脛骨前肌;主要用力肌肉是肱二頭肌、三角肌、背闊肌,與風(fēng)阻劃船器的略有差異。無論是從運(yùn)動學(xué)還是肌電學(xué)的角度分析,專業(yè)組的主要肌肉都遵循大肌群帶動小肌群的協(xié)調(diào)用力原則,下肢帶動上肢依次運(yùn)動的用力方式?jīng)]有改變,用力比較合理。普通組由于動作的明顯差異,在這里不予說明。本研究采用vicon三維運(yùn)動捕捉和表面肌電系統(tǒng)同步測試分析等手段,對水阻劃船器拉槳技術(shù)動作進(jìn)行運(yùn)動學(xué)和肌電學(xué)分析,對于我們?nèi)嬲J(rèn)識賽艇拉槳技術(shù),提高賽艇運(yùn)動訓(xùn)練質(zhì)量提供參考依據(jù),以及為賽艇力量耐力訓(xùn)練探索新的測試手段和方法具有重要意義。
[Abstract]:In order to study the kinematic characteristics of each part of the body during the paddle stage of the water resistance rower, the kinematics characteristics and muscle force characteristics of the paddle stage of the water resistance rowing vessel were analyzed by motion capture. In this paper, 6 young male rowers and 6 ordinary college students are selected as experimental objects, and the simulated rowing analysis of male juvenile rowers and ordinary athletes under the three dimensional angle of view of the paddle pulling technique of the water resistance rowers is carried out. Three dimensional motion capture system and surface myoelectric system were used to collect the kinematic parameters and original electromyography (EMG). This paper analyzes and discusses the influence of the indexes, posture and muscle force on the movement of the water resistance rower, and then compares the characteristics of different groups with the situation of wind resistance rower in the professional training. The research shows that, in terms of resistance characteristics, the results of joint angular velocity indirectly verify that the paddle of the hydroresistive rower is from the rapid kick to the upper limb after exertion to the front of the rib, and the whole period of the paddle is to maintain a constant resistance. The characteristics of resistance are different from those of wind drag rowers, and in kinematics, No significant difference was found in all joints between the professional group and the normal group, and there was significant difference in the peak angular velocity between the wrist joint and the knee joint in the professional group, and the peak value of angular velocity was not found in all joints in the normal group. There was significant difference in surface electromyography. In the process of pulling oars, the muscles of professional group were quadriceps femoris muscle, erector muscle, biceps brachii muscle, deltoid muscle, latissimus dorsi muscle, anterior tibial muscle, and the main muscle was biceps brachii muscle, deltoid muscle and latissimus dorsi muscle. Slightly different from wind resistance rower. No matter from the angle of kinematics or electromyography, the major muscles of the major group follow the principle of coordinating force of the major muscle group to drive the small muscle group, and the force mode of the lower extremity driving the upper limb in turn has not changed, and the force is more reasonable. The common group is not explained here because of the obvious differences in action. In this study, the kinematics and electromyoelectric analysis of the paddle technique of the water resistance rower were carried out by means of vicon three-dimensional motion capture and synchronous testing and analysis of the surface electromyography system. It is of great significance to improve the quality of rowing training and to explore new test methods for rowing strength endurance training.
