There are a lot of disciplines in science that are evidence based. But not so in coaching motor skills. In the following article Bain and Mc Gown show, that there is still a methodical traditionalism that ignores evidence based research.
Bain/McGown use three questions from an article that recommends the use of part to whole progressions and they show the evidence based error:
1. Is it always better to teach skills to players of all levels strictly by repetition of the whole skill?
2. Is it appropriate for younger players or players that have not yet imprinted proper motor patterns to learn skills by performing only part of the skill?
3. Should a distinction be made for what training methods are appropriate for more advanced players as compared to players in
their early years of training?
