From a young age, it is important that athletes follow a multilateral training program that focuses on overall development that will lead to more successful performances at a later stage. Early specialisation is discouraged. Specialisation can lead to a narrow development of muscles and systems, overtraining and overuse injuries, boredom and burnout and training for the wrong event. Any one of, or a combination of these things can cause a person to drop out of the sport early.
A multilateral development will lead to slower performance improvement but a longer athletic life. Specialisation will generally take place after athletes have achieved a solid foundation and when they have the desire to specialise in a particular sport or event.
