motion, balance and stability Flashcards
What is the study of biomechanics?
The study of human movement that applies the natural laws of physics and mechanics to enhance performance and safety.
What are the two main branches of biomechanics?
- Kinetics: Investigates forces acting on the body
- Kinematics: Investigates movements of the body
Why is biomechanics important in sports?
- It helps choose the best technique for movement
- It reduces the risk of injury
- It aids in designing better equipment
What does motion refer to in the context of sports?
The specific path or movement of a body or object manipulated by the human body.
What are the two main types of balance in sports?
- Static: Maintain balance while stationary
- Dynamic: Maintain balance while moving
What is the centre of gravity?
The point at which all the weight of an object is evenly distributed and about which the object is balanced.
How does the centre of gravity differ in rigid and hollow objects?
- Rigid objects (e.g., cricket ball): Centre of gravity is in the center
- Hollow objects (e.g., tennis ball): Centre of gravity is in the hollow center
How does the position of the centre of gravity vary?
It varies according to the position of the body.
What is the base of support?
An imaginary line drawn around all parts of the body in contact with the ground.
How does the size of the base of support affect stability?
A larger base of support generally increases stability, especially when the centre of gravity is within it.
Fill in the blank: The larger the base of support, generally the more _______.
stable
True or False: The centre of gravity remains constant regardless of body position.
False
What happens to the centre of gravity when standing on one foot?
It is shifted over onto the one foot to increase stability.
