Outside the box

A look outside the box into volleyball. Dr. Carl McGown, one of the world’s most influential coaches, has died in the US. I have already reported on this. At this point I will not point out his many successes. Perhaps without knowing it, every coach of the world of volleyball applies his knowledge and not only volleyball coaches benefit from the knowledge that comes back to Carl McGown. I have also called on him in this blog several times. Outside the box weiterlesen

Part-to-whole training

„Regrettably, concluding and/or seeking to demonstrate that “part-to-whole training progressions” are a preferred instructional paradigm simply because such progressions appear to “make sense”, … This ignores nearly a century of scientific evidence and volumes of published research that have conclusively demonstrated that part progressions have minimal transfer to the whole skill and in a number of scientific studies part training methods have actually demonstrated negative transfer.“

Blocked vs random practice!Carl McGown, AVCA Hall of Famer

„The random versus blocked practice methods represent a fundamental paradox regarding athletic performance during training and subsequent performance during competition. Based on performance measurements during practice, blocked activities, in which athletes repeatedly rehearse the same task, result in superior performance during the training session. In comparison, performing tasks and skills in random order decreases skill acquisition during training. Consequently, based on measurement of performance effects during practice, many coaches and players believe that blocked practice is superior to random practice. Such a conclusion however, mistakenly assumes a positive correlation between performance in practice and long-term skill retention. The paradox arises from the fact Play the game weiterlesen


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.Carl McGown, AVCA Hall of Famer

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?

Evidence based motor learning

Carl McGown“Research has led to the identification of a number of evidence-based motor learning principles, which, when properly understood and applied, can have a significant impact on athletic development and achievement. It is therefore surprising that despite its rich heritage and an overwhelming body of scientific literature, motor learning principles remain poorly understood and/or incorrectly applied by a large number of individuals in the coaching profession.”
