FAQs on Important Questions for Practice - Physiology and Sports - Physical Education Class 12(XII) - Notes & Model Test Papers - Humanities/Arts

1. How does physiology affect sports performance?
Ans. Physiology plays a crucial role in sports performance as it determines how the body functions during physical activity. Factors such as oxygen delivery, energy production, muscle strength, and endurance are all influenced by physiological processes. Understanding and optimizing these processes can enhance athletic performance.
2. What are the physiological adaptations that occur with regular exercise?
Ans. Regular exercise leads to several physiological adaptations in the body. These include an increase in cardiovascular fitness, improved lung function, increased muscle strength and endurance, enhanced flexibility, and improved body composition. These adaptations occur due to the body's ability to adapt and respond to the demands placed on it during exercise.
3. How does the body regulate temperature during physical activity?
Ans. The body regulates temperature during physical activity through a process called thermoregulation. When body temperature rises, blood vessels near the skin dilate, allowing more blood to flow near the surface and release heat. Sweating also occurs, which helps to cool the body as the sweat evaporates from the skin. These mechanisms work together to maintain optimal body temperature during exercise.
4. How does nutrition impact sports performance and physiology?
Ans. Nutrition plays a vital role in sports performance and physiology. Proper nutrition provides the body with the necessary nutrients to support energy production, muscle repair and growth, and overall health. Adequate intake of carbohydrates, proteins, fats, vitamins, and minerals is essential for optimal athletic performance. Additionally, hydration is crucial for maintaining proper physiological function during exercise.
5. How does the respiratory system adapt during exercise?
Ans. The respiratory system undergoes several adaptations during exercise to meet the increased oxygen demand of the body. These adaptations include an increase in breathing rate and depth, improved lung capacity, enhanced oxygen uptake and delivery to the muscles, and increased efficiency in removing carbon dioxide. These adaptations allow for better oxygen exchange and improved overall respiratory function during physical activity.
