The major goal of biomechanics of sport and physical exercise is to improve performance in given sport or physical exercise.
In a wider context the goal of biomechanics of sport and physical exercise is also to increase physical fitness. For instance the correct biomechanics of running allows athletes to carry out regular physical exercise for long enough periods of time without being seriously limited by injuries and their consequences.
The secondary goal of sport biomechanics is to provide recommendations for injury prevention and rehabilitation.
The secondary goal of sport biomechanics is strongly related to the main goal because a healthy athlete will perform better than an athlete plagued with frequent injuries. How can biomechanics fulfil its goals?
