  • Identify roles within the rehabilitation team
  • Apply graded exposure and specificity

Before this lesson

Why this matters

Exercise is central to both preventing and recovering from injury. A few principles explain most good practice.

Load and capacity

Tissues adapt to the loads they experience. Injury often occurs when load exceeds current capacity — a sudden spike in running, a heavy unaccustomed lift, a new sport. Rehabilitation and prevention aim to raise capacity and manage load [gabbett2016].

Key principles

PrincipleMeaning
MechanotherapyMechanical loading stimulates tissue repair and adaptation [khan2009]
Progressive overloadGradually increase demand as tolerance improves
SpecificityProgress towards the person’s real tasks
Graded exposureReintroduce feared or demanding activities step by step
IndividualisationAdjust to the person, tissue and context
EducationHelp people understand pain and recovery

Prevention evidence

A meta-analysis of randomised trials found strength training substantially reduced sports injuries, while stretching alone showed no protective effect [lauersen2014].

The team

Doctor (diagnosis, medical care), physiotherapist (rehabilitation lead), S&C coach/trainer (strength, conditioning, return to performance), sport coach (skill and load), dietitian and psychologist as needed.

Common mistakes and misconceptions

Case study

A recreational runner increases from 20 to 45 km/week in a month and develops shin pain. After medical review excludes a stress fracture, the plan reduces running, adds calf and hip strength work, and rebuilds volume gradually.

  1. Describe the load–capacity model with an Achilles example.
  2. Map the roles of each team member for an injured footballer.
  3. Why is complete rest rarely the best long-term strategy?

Key takeaways

  • Many sports injuries reflect load exceeding the tissue’s current capacity.
  • Rehabilitation progressively rebuilds capacity toward the demands of the person’s life or sport.
  • Strength training is among the most effective injury-prevention strategies; stretching alone shows little effect.
  • Rehab is a team effort, with clear roles and communication.
