UNIT-8 KINESIOLOGY AND BIOMECHANICS IN SPORTS
1. Definition and Importance of Kinesiology and Biomechanics in Sports
Kinesiology
Kinesiology is the study of human body movements, especially muscles and joints
involved in movement.
Biomechanics
Biomechanics is the application of mechanical laws to understand human
movement in sports.
1.Importance in Sports:
1. Helps in improving sports performance
2. Corrects technique and posture
3. Prevents sports injuries
4. Increases efficiency of movement
5. Helps coaches in scientific training
2. Principles of Biomechanics
Principles of biomechanics help in understanding movement efficiency.
1. Force – Greater force produces greater movement.
2. Balance – A wider base of support gives better balance.
3. Leverage – Longer lever increases speed and distance.
4. Coordination – Proper coordination improves performance.
5. Stability – Lower centre of gravity increases stability.
3. Kinetics and Kinematics in Sports
Kinetics
Kinetics deals with the forces that cause movement.
Examples:
1. Muscle force 2. Gravity 3. Friction
Kinematics
Kinematics deals with motion without considering forces.
Includes:
1. Speed 2.Velocity 3.Acceleration 4.Distance and displacement
Example: Running speed of an athlete.
