Summary of Physiology and Injury in sports | One shot | Class 12 | Unit 7 | Physical education
The video covers the topic of Physiology and Injuries in Sports in Physical Education.
Physiology in Sports
- Physiology is the study of how exercise and sports activity alter the function and structure of the body.
- Physiological factors determine components of physical fitness such as strength, speed, endurance, and flexibility.
- Factors determining strength include muscle size, body weight, and muscle composition.
- Factors determining speed include mobility of the nervous system, muscle composition, explosive strength, flexibility, and biochemical reserves.
- Factors determining endurance include aerobic capacity, lactic acid tolerance, movement economy, and flexibility.
- The impact of exercise on the muscular system includes changes in muscle size and shape, formation of more capillaries, toned muscles, and improved connective tissue.
- The cardiorespiratory system is also affected by exercise, leading to increased heart size, decreased resting heart rate, and improved stroke volume.
Sports Injuries
- Common sports injuries include soft tissue injuries, bone and joint injuries, fractures, dislocations, and sprains.
- Soft tissue injuries include contusions, sprains, strains, abrasions, lacerations, and lesions.
- Bone and joint injuries include stress fractures, greenstick fractures, comminuted fractures, transverse fractures, oblique fractures, and impacted fractures.
- Prevention and treatment methods for each type of injury are discussed in detail throughout the video.
