Why do injuries happen?
Common Causes of Sports Injuries can be divided into Intrinsic Factors and Extrinsic Factors.
Intrinsic Factors are those that involve aspects of your physical makeup: a number of biomechanical factors, flexibility (too much / too little), strength (muscle imbalances or weaknesses), leg length differences, posture, foot shape and movement during exercise, and others.
Extrinsic Factors include aspects of your training/exercise programme, technique, equipment, surfaces upon which you are training on, and environment.
Identifying these factors is important, since many can be changed to speed recovery and prevent recurrence. Sometimes it is obvious, but you may need a trained eye. The use of video analysis, gait assessment and input from a coach or one or more members of a sports medicine team may be helpful.
