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.

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.
