What is Biomechanics?
The study of internal and external
forces acting on the body segments,
and the effects produced by these
The principles of engineering,
specifically mechanics, applied to
constant state of acceleration
Kinetics of Constant Kinematics Kinetics
motionless systems velocity
Kinematics: study of the variables that describe
or quantify motion
Kinetics – study of the variables that cause or
Problems studied by biomechanists
Biomechanists use the principles of
mechanics in the analysis of human
movement to answer questions such as:
1. How can human performance be
2. How can injuries be prevented?
3. How can rehabilitation from injury be
Areas of Biomechanics
By understanding and applying mechanical
concepts, sports biomechanists assess the
most optimal way to move the body in
order to achieve maximal performance,
whilst minimizing risk of injury.
Sequential motion: the acceleration
of body segments occurs sequentially,
in a proximal to distal fashion
Ideal coordination pattern for most
throwing and striking skills.
The goal is to design machines and
the workplace to reduce repetitive
stress on workers’ joints.
Clinical biomechanists analyze the
mechanics of injured patients and
provide feedback (biofeedback) to
restore normal function.
