Unit-8
1.Meaning and importance of Biomechanics
in sports.
2.Types of movements.
(Flexion,Extension,Abduction and
Adduction.)
3.Newton’s laws of motion and its
application in sports

4. Biomechanics and sports.
Meaning
 Biomechanics is essentially the study of
forces and their effects on living bodies. When
used for the study of sports performance, the
forces of importance can be the internal
forces produced by muscles, the forces the
human imparts to objects, such as balls, bats
or pedals, or the forces the body experiences
from the environment, such as occur during
collisions, jump landings, or from fluid media
like water or wind resistance.

5. Biomechanics and sports.
Meaning
 . Essentially sport and exercise biomechanics is focused
on analysing the physiological mechanics of human
movement. ... Generally the primary goals of
sports biomechanics are: Improve athletic performance
by identifying and applying optimal technique. Prevent
injury and speed up recovery.
 Biomechanics is a tool that can be used
in sport medicine to identify forces and mechanical
energy that cause injuries. It helps to understand how
injuries originate, how to avoid them
during sport performance, and how to identify exercise
suitable for injury prevention and rehabilitation.

6. Biomechanics and sports.
Importance
Biomechanics helps in improvement of the plan of sport equipment.
Designs of various types of equipment are assessed by the
biomechanists and after assessment they make/propose changes in
equipment that can be useful in enhanced performance. It is the
aftereffect of biomechanics that in pole vault event fiber shafts are
utilized rather than bamboo shafts in light of the fact that the fiber is
more adaptable than bamboo. Designs of shoes are likewise changed
to enhance friction which helps in upgrade speed and keep up body
balance. Design of dresses are likewise changed for instance the
costume of swimmers and outfit of athletes to diminishing water and
air resistance. Biomechanics helps in comprehension the body
structure. Coaches with biomechanics knowledge can distinguish
which body structure is proper for which sport, this will enhance sports
and sports training result.Through Biomechanics knowledge
competitors know how to use energy. Competitors can accomplish
better outcomes by expending energy in an oversaw way.

7. Biomechanics and sports.
Importance
 For instance, a competitor can save energy by wiping out undesirable
movements while running. Injuries are extremely normal in games and it
influences the performance of the players. A few injuries are serious to the
point that it requires a long time for recuperation.With the assistance of
sports biomechanics various types of safety equipment are built which are
imperative and valuable in sports to save competitors from injuries, for
instance shin protector is utilized for football and hockey players. Pad,
gloves, elbow guard, thigh guard, helmet and so on are utilized for cricket.
The knowledge of biomechanics is vital for players, coaches, physical
education teachers, trainers to forestall injuries. Sports biomechanics
principles are based on fact, lets us know that what sort of principles to be
actualizes to decrease odds of injuries. For instance, while taking high
catch in cricket fielder moves his hands back toward the chest while
catching the ball, in this way he is expanding the distance and diminishing
the force of ball.Through Biomechanics science we concentrate some
extraordinary variables which impact sports performance.The Factors are
streamlined, hydrodynamic, heading of air, rotation of object, releasing
angle, force act on object, equilibrium, lever and so forth. By utilizing these
variables competitors or games individual can improve their games
performance.

8. Importance of Biomechanics and sports
Improves performance in sports:
1- Principles of biomechanics tell us about right techniques,
effective and result oriented posture to get more efficient
results by applying minimum muscular force which in turn
improves performance in sports

9. Importance of Biomechanics and sports
2-IMPROVEMENT INTECHNIQUE:
 With the use of biomechanics it is possible to specify motor actions or positions
that can increase sport performance. Sport technique is a physical action of an
athlete which leads to the best possible execution of a physical motion,
technique Improvement With the use of biomechanics it is possible to specify
motor actions or positions that can increase sport performance. Sport technique
is a physical action of an athlete which leads to the best possible execution of a
physical motion,

10. IMPROVEMENT IN TECHNIQUE

11. Importance of Biomechanics and
sports
 3- DEVELOPMENT OF IMPROVED SPORTS EQUIPMENT:
 The principles of biomechanics are used to modify the sports equipments. For example, tee shirts, studs,
spikes, swimming costumes, hockey sticks, different size footballs and low weight helmets for protection

12. Importance of Biomechanics and
sports
 4- IMPROVE INTRAININGTECHNIQUES
 : A teacher can analyze the player’s movement or action with the help of the
biomechanical principles. It helps in improving the training techniques..

13. Importance of Biomechanics and
sports
 5- PREVENTS SPORTS INJURIES:
 it helps to find out the factors or the forces that can lead to the injuries
during the game situation. It also helps in prevention of the sports
injury.

14. Importance of Biomechanics and
sports
 6-KNOWLEDGE OF SAFETY PRINCIPLES:
 Biomechanics gives the understanding to analyze different movements that can
harm the player.The teachers remove those unnecessary and harmful
movements

15. Types of movements
1.Flexion
2.Extension
3.Abduction
4.Adduction

16. Types of movements-
Flexion
 Flexion refers to a movement that
decreases the angle between two body
parts.


17. Types of movements-
Extension
 Extension is the opposite of flexion, describing a
straightening movement that increases the angle between body
parts. For example, when standing up, the knees are extended.
When a joint can move forward and backward, such as the neck
and trunk,

18. Types of movements-
Abduction
The movement of a limb or other part away
from the midline of the body, or from
another part.

19. Types of movements-
Adduction
 Adduction is a movement towards the
midline.

20. Types of movements-

21. Three planes of the Body

22. Planes of the Body

23. Newton’s First Law of Motion and its
application in sports

25. Newton’s Second Law of Motion and its application
in sports

27. Newton’s Third Law of Motion and its
