Meaning of Physiology
Physiology is the branch of science that studies the functions and activities of living organisms and their body parts. In sports, physiology helps us understand how different systems of the body respond to exercise and training.
Knowledge of physiology helps athletes improve performance, maintain fitness and prevent injuries.
Important: Physiology explains how the body works during exercise and sports performance.
Importance of Physiology in Sports
- Improves sports performance.
- Helps in scientific training.
- Enhances recovery.
- Prevents injuries.
- Improves physical fitness.
- Develops endurance and strength.
Effects of Exercise on Muscular System
- Increase in muscle strength.
- Increase in muscle size (Hypertrophy).
- Improved muscular endurance.
- Better blood supply to muscles.
- Increased flexibility.
Effects of Exercise on Cardiovascular System
- Stronger heart muscles.
- Increased cardiac output.
- Improved blood circulation.
- Lower resting heart rate.
- Better oxygen transport.
Effects of Exercise on Respiratory System
- Increased lung capacity.
- Improved oxygen intake.
- Better respiratory efficiency.
- Enhanced endurance.
- Improved breathing control.
Sports Injuries
Sports injuries are injuries that occur during sports participation, exercise or physical activities. They may affect muscles, bones, ligaments, tendons and joints.
Sports injuries can reduce performance and may require medical treatment and rehabilitation.
Causes of Sports Injuries
- Poor warm-up.
- Overtraining.
- Incorrect technique.
- Lack of fitness.
- Unsafe equipment.
- Accidents during play.
Types of Sports Injuries
Sports injuries can be classified according to the body part affected and the severity of damage.
Sprain
A sprain is an injury to a ligament caused by overstretching or tearing. It commonly occurs in the ankle, knee and wrist joints.
Strain
A strain is an injury to muscles or tendons caused by excessive stretching or overuse.
Fracture
A fracture is a break or crack in a bone. It may be simple, compound or stress fracture.
Dislocation
Dislocation occurs when bones at a joint move out of their normal position.
Abrasion
An abrasion is a skin injury caused by rubbing against a rough surface.
First Aid in Sports Injuries
First aid is the immediate care provided to an injured person before professional medical treatment becomes available.
- Reduces pain.
- Prevents further injury.
- Promotes faster recovery.
- Provides immediate relief.
PRICE Treatment
PRICE is the most commonly used method for treating soft tissue injuries.
- P - Protection
- R - Rest
- I - Ice
- C - Compression
- E - Elevation
Important: PRICE treatment helps reduce swelling, pain and tissue damage.
Prevention of Sports Injuries
- Proper warm-up before activity.
- Correct sports techniques.
- Use appropriate sports equipment.
- Balanced training programmes.
- Adequate recovery and rest.
- Proper nutrition and hydration.
- Regular fitness training.
Rehabilitation
Rehabilitation is the process of restoring normal function after an injury. It helps athletes return to sports safely and effectively.
- Physiotherapy.
- Stretching exercises.
- Strengthening exercises.
- Gradual return to activity.
