Preventing Injury and Types of Injury

This lesson covers injury prevention and the types of injury required by the Edexcel GCSE PE specification (1PE0). You must know the difference between acute and overuse (chronic) injuries, be able to name and describe specific examples of each, and understand how injuries can be prevented through appropriate measures.

Types of Injury

Edexcel divides injuries into two categories: acute and overuse (chronic).

Acute Injuries

Definition: Injuries that occur suddenly as a result of a specific incident or trauma (e.g. a tackle, fall, collision or sudden movement).

Injury	Description	Cause	Sporting Example
Fracture	A partial or complete break in a bone	A direct blow or excessive force applied to a bone	A footballer's leg being struck by a tackle
Dislocation	A bone is forced out of its normal position at a joint	A strong impact or force applied to a joint	A rugby player's shoulder dislocating during a tackle
Sprain	Damage to a ligament (the tissue that connects bone to bone at a joint) through overstretching or tearing	A sudden twist or wrench of a joint beyond its normal range	An ankle sprain from landing awkwardly after a jump in basketball
Strain	Damage to a muscle or tendon (the tissue that connects muscle to bone) through overstretching or tearing	A sudden forceful contraction or overstretching of a muscle	A hamstring strain during sprinting

Exam Tip: The most common confusion is between sprains and strains. Remember: sprain = ligament (bone to bone), strain = muscle/tendon (muscle to bone). A useful memory aid: SprAin = ligAment, strAin = muscle/tendon... or: "Sprains are at joints (ligaments), strains are in muscles."

Overuse (Chronic) Injuries

Definition: Injuries that develop gradually over time as a result of repeated stress or overuse of a particular body part.

Injury	Description	Cause	Sporting Example
Tennis elbow (lateral epicondylitis)	Inflammation of the tendons on the outside of the elbow	Repeated gripping and twisting movements of the forearm	A tennis player repeatedly performing backhands
Shin splints	Pain along the shin bone (tibia) caused by inflammation of the muscles, tendons and bone tissue	Repeated impact (running on hard surfaces), increasing training too quickly	A long-distance runner training on tarmac
Stress fractures	Small cracks in a bone caused by repeated loading	Repetitive impact over time without adequate rest	A gymnast repeatedly landing on hard surfaces; a distance runner increasing mileage too fast
