2. Biomechanics
 A combination of two words “Bio” & “Mechanics”
 Bio – means – Living Organisms
 Mechanics – is a branch of Physics which deals with the motion and causes of
motion
 Actual application of laws and principles of physics in to the systems/body
 Definition of Biomechanics
“Biomechanics refer to the application of Mechanical principles and laws to
the living structures or biological properties specifically to the loco-motor system
of the living body”

3. Sports Biomechanics
 “ Sports Biomechanics refer to the application of Mechanical principles and laws
to the field of sports or athletes specifically to improve performance of athletes”

5. Mechanics
 Have two branches –
 Kinetics – which deals with the cause of motion
 Why ?
 Eg . Force , pressure , impact, Gravity etc
 Kinematics – deals the description of motion in terms of time, displacement ,
speed , etc
 How ?
 Eg. How long ,how much speed etc

6. Division of Kinetics and Kinematics
 Static and Dynamics are the two branches of both kinetics and kinematics
 STATICS – applied on a body at REST phase
 DYNAMICS – applied on a body at MOTION phase
 REST – if there is no changes in the size , shape, posture , position etc of body
are called as movement
 MOVEMENT – Any changes occurring in the size , shape, posture , position etc
of body are called as movement

8. Goals of Sports Biomechanics
 Performance improvement
 Technique improvement
 Movement Quality improvement
 Equipment improvement
 Injury prevention and Rehabilitation
 Reduce the chance of injury by developing equipment
 Technical correction
 Concepts of force transfer
