FAQs on Chapter 10 - Biomechanics and Sports, Chapter Notes, Class 12, Physical Education - Physical Education Class 12(XII) - Notes & Model Test Papers - Humanities/Arts

1. What is biomechanics in sports?
Ans. Biomechanics is the study of the mechanical principles of living organisms, especially their movement and structure. Biomechanics in sports refers to the application of these principles to sports performance, injury prevention, and rehabilitation.
2. How does biomechanics help in sports performance?
Ans. Biomechanics helps in sports performance by analyzing the mechanics of human movement and identifying ways to optimize it. It can help in improving techniques, achieving greater power, and reducing the risk of injury. Biomechanics also helps in designing sports equipment that can enhance performance.
3. What are some common biomechanical principles in sports?
Ans. Some common biomechanical principles in sports are force, motion, balance, stability, and momentum. Understanding these principles helps in analyzing and improving sports techniques.
4. How does biomechanics contribute to injury prevention in sports?
Ans. Biomechanics contributes to injury prevention in sports by identifying the risk factors that may lead to injuries and developing strategies to reduce them. It helps in understanding the mechanics of different sports movements and identifying ways to reduce the stress on the body.
5. What are some examples of how biomechanics is used in sports?
Ans. Biomechanics is used in sports in various ways. Examples include analyzing the optimal technique for throwing a ball, designing sports equipment such as running shoes and golf clubs, and studying the effects of different playing surfaces on the body. Biomechanics is also used to understand the impact of injuries on sports performance and to develop rehabilitation programs.
