Some simple applications of Newtonian mechanics and materials sciences can supply correct approximations to the mechanics of many biological systems. Applied mechanics, most notably mechanical engineering disciplines such as continuum mechanics, mechanism analysis, structural analysis, kinematics and dynamics play prominent roles in the study of biomechanics.,方法,生物力学与工程密切相关 ,因为它经常使用传统的工程科学分析来生物系统。一些简单的对牛顿力学和材料科学的应用可以提供正确的逼近力学的许多生物系统。应用力学,最明显的机械工程学科如连续介质力学,机制分析,结构分析,运动学和动态力学在生物力学研究方面扮演重要角色,method,Usually biological systems are more complex than man-built systems. Numerical methods are hence applied in almost every biomechanical study. Research is done in an iterative process of hypothesis and verification, including several steps of modeling, computer simulation and experimental measurements.,方法,通常生物系统比人工建立的系统更复杂相比。因此数值方法几乎应用在了每一个生物力学研究领域。研究是一个在假说和验证中完成的迭代过程,包括几个步骤：建模,计算机仿真和实验测量.,Sport biomechanics,In sports biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance and to reduce sport injuries as well. Elements of mechanical engineering , electrical engineering , computer science , gait analysis , and clinical neurophysiology are common methods used in sports biomechanics.,运动生物力学,在运动生物力学中,力学定律的运用是为了更好地理解运动性能，同时减少运动损伤。机械工程，电气工程，计算机科学，步态分析，临床神经生理学中的一些方法也常应用于运动生物力学中。,Application,The study of biomechanics ranges from the inner workings of a cell to the movement and development of limbs, to the mechanical properties of soft tissue, and bones. As we develop a greater understanding of the physiological behavior of living tissues, researchers are able to advance the field of tissue engineering, as well as develop improved treatments for a wide array of pathologies.,应用,生物力学的研究范围从内细胞的运作与发展，到软组织和骨头的力学性能 。当我们需要更好的理解生理行为活组织时，研究人员便推动组织工程之一领域的发展，以及开发改进治疗病理的一个宽数组。,Application,Biomechanics is also applied to studying human musculoskeletal systems. Such research utilizes force platforms to study human ground reaction forces and infrared videography to capture the trajectories of markers attached to the human body to study human 3D motion. Research also applies electromyography(EMG) system to study the muscle activation. By this, it is feasible to investigate the muscle responses to the external forces as well as perturbations.,应用,生物力学也应用于研究人类肌肉骨骼系统。这样的研究利用力学平台来研究人的地面活动和用红外摄像来捕获标记，以便研究人的三维运动。研究也同样可以运用肌电图系统来研究了肌肉活动。通过这个,可行的研究肌肉对外部力量以及扰动的反应。,External links,If you want to know more information about biomechanics, please link the following website in your computer. http:/en.wikipedia.org/wiki/Biomechanics,Thanks for your watch!,iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii,
