Introduction

What is Biomechanics?





The study of internal and external
forces acting on the body segments,
and the effects produced by these
forces.




The principles of engineering,
specifically mechanics, applied to
human movement.

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
enhanced?


2. How can injuries be prevented?


3. How can rehabilitation from injury be
expedited?

Areas of Biomechanics



Sports Biomechanics




Occupational Biomechanics




Clinical Biomechanics

Sports 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.

Occupational Biomechanics


The goal is to design machines and
the workplace to reduce repetitive
stress on workers’ joints.

Clinical Biomechanics


Clinical biomechanists analyze the
mechanics of injured patients and
provide feedback (biofeedback) to
restore normal function.
