Meaning and Concept of Biomechanics

1. Meaning and Concept of Biomechanics By Dr. Ajay Kumar

2. Definition of 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 (kinesiology) which has to do the effect of force upon the state of motion or rest of living bodies.

3. 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.

4. 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.

5. 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.

6. Definition of Biomechanics • Biomechanics is the research and analysis of the mechanics of living organisms or the application and derivation of engineering principles to and from biological systems.

7. 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

8. 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.

9. Historical Aspects of Biomechanics • C.H.McCloy of university of IOWA had practically showed that performance could be improved by the application of appropriate mechanical principles. • He was the first to develop a course in the Mechanical Analysis of Motor Skills.

10. Historical Aspects of Biomechanics • Contribution of Ruth Glassow of the university of Winconsin as a pioneer in cinematographic analysis of human motion also developed the interest among the physical educators towards this area.

11. INTRODUCTION • Mechanics -The laws of physics related to motion. • Mechanics–The scientific study which provide accurate answers to what is happening, why it is happening and to what extent it is happening is called mechanics.

12. Major Divisions of Mechanics • Statics - The study of equilibrium or balance. • Statics – Statics covers situation in which all forces acting on a body are balanced and the body is in equilibrium

13. Major Divisions of Mechanics • Dynamics - The study of disequilibrium. • Dynamics - The branch of mechanics which deals with bodies subject to unbalanced forces is called dynamics

14. Subdivisions of Major branches • Kinematics --» Descriptive analysis of space and time. Study of qualities of motion, speed, velocity, acceleration. How the motion appears. • Kinetics --» Causal analysis. Study of forces involved in causing and resulting from motion. What cause or result from motion.

15. Examples • Some simple examples of biomechanics research include the investigation of the forces that act on limbs, the aerodynamics of bird and insectflight, the hydrodynamics of swimming in fish
