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.

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

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.

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.

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 insect
  flight, the hydrodynamics of swimming in fish
