2. What is it?
 The study of the structures and function of
Biological systems by means of the methods of
Mechanics.
 The Science concerned with the internal and
external forces acting on the human body and
the effects produced by these forces.

4. AGENDA
Antiquity
650BC – 200AD
Middle Ages
200AD – 1450AD
Italian Renaissance
1450AD – 1600AD
Scientific Revolution
1600AD – 1730AD
Enlightenment
1730AD – 1800AD
The Gait century
1800AD – 1900AD
The 20th century and beyond 1900AD - ….

5.  Exercise and Sport biomechanics
 Orthopedic biomechanics
 Occupational biomechanics

6. 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.

8.  Design of Artificial limbs, joints, and orthoses
to improve functional movement capacity
 Study of natural and artificial biological tissues

10.  Ergonomics and Human Factors
 Reduction of workplace injuries

12. Using Biomechanics to Improve
Sports Apparel & Equipment

New developments in sport apparel are aiding
Olympic athletes improve their winning odds in a
wide range of events.

Such apparel can provide advantages that mean the
difference between silver and gold in elite
competitions.

13. A Few Examples

Swimming
 TYR Aqua Shift Suit, worn by Erik Vednt, U.S. silver
medalist
 Speedo Fastskin FSII, worn by Michael Phelps in
Sydney Olympics
 Tennis
 Composite Tennis Racket

14. Swimming
SPEEDO
 Fastskin II (Speedo) uses rough and
smooth material on different parts of
the body
 Seams made of high-stretch thread
follow in the direction of water flow
 Raised ridges on chest and back
create microscopic vortices that the
company says reduces drag
 Titanium scales on suits inner
forearm area are designed to help the
swimmer “grip” the water

15. Tennis Racket
 Old vs. New
 Change in material
 Advancement in structural design
 Reduction in potential vibration which causes
“Tennis Elbow”

16.  CompuTrainer by RacerMate, Inc.
• Utilizes state of the art Interactive 3D graphics to
simulate hills, curves, split screens and panoramic
helicopter views.
• Hundreds of preloaded courses and the capability to
create any course.
 SpinScan is a graphic video biofeedback used to evaluate
the impact of small adjustments to bike position to find
a dynamic bike fit.

18. Movement Analysis Software

The SwingTrainer™ is a complete swing analysis system that
monitors all aspects of sports movements involving golf clubs,
baseball bats, tennis racquets and hockey sticks. Eight sensors
precisely monitor the position and orientation of 36 points on the
body and sports object at the rate of 144 times per second. The
data is used to render a model of you and provide data on such
characteristics as shoulder rotation, club or bat speed, balance,
center of mass, etc.

19.  If a ball spins in flight, it will drag some of the air close to the
surface with it. This creates an area of high pressure and an area
of low pressure on opposite sides of the ball.
 This pressure imbalance will make the ball curve in flight.

20. Technology And Training
Improvement

A qualitative biomechanical analysis of an
actual performance should be done to identify
deficiencies in technique, strength, power,
endurance, or flexibility.

Prescribe drills and exercises that are specific
to the aspect of the skill that is deficient, or
that closely simulates the specific exercise
used in the technique training.
