Meaning and Concept of Biomechanics By Dr. Ajay Kumar

Definition of Biomechanics When the study of mechanics is limited to living structure especially the human body, is called biomechanics. When the study of mechanics is limited to living structure especially the human body, is called biomechanics. Biomechanics may be considered to be that aspect of the science of movement Biomechanics may be considered to be that aspect of the science of movement (kinesiology) which has to do the effect of force upon the state of motion or rest of living bodies.

Definition of Biomechanics A field that combines the disciplines of biology and engineering mechanics and utilizes the tools of physics, mathematics, and engineering to quantitatively or qualitatively describe the properties of biological materials.

Definition of Biomechanics The application of physics and mechanics to the study of movement. In sport, biomechanics is especially concerned with how the human body applies forces to itself and objects with which it comes into contact, and how the human body is affected by external forces.

Definition of Biomechanics A study of the fundamental principles of mechanics as they apply to movement and skills, aid the teacher and coach in the analysis of skills for the purpose of correction error, leads to the development of technique and the intelligent evaluation of new technique as they come along A study of the fundamental principles of mechanics as they apply to movement and skills, aid the teacher and coach in the analysis of skills for the purpose of correction error, leads to the development of technique and the intelligent evaluation of new technique as they come along

Historical Aspects of Biomechanics Aristotle wrote the first book on biomechanics, De Motu Animalium, or On the Movement of Animals. He not only saw animals' bodies as mechanical systems, but pursued questions such as the physiological difference between imagining performing an action and actually doing it.
