The link is to a TED ED video that is very compelling. I think the explanation of the biology of how the brain and the nervous system work is well worth the five minutes it takes to watch the video. Since it goes by fast, I’ve taken some notes:
Quality effective practice is consistent, intensely focused, targets content or weaknesses that lie at the edge of our capability. To practice effectively we need to focus on the task at hand, eliminate distractions (Facebook is mentioned, but there are many distractions vying for attention). Then, start out slowly, or in slow motion. We all know that slow practice is the “go to” technique for elite performers. Interesting to learn that coordination is built with repetitions, whether correct or incorrect. If we gradually increase the speed of the quality repetitions, we have a better chance of doing them correctly. (I want to read more about this.)
Frequent repetitions with allotted breaks are common practice habits of elite performers. In fact, the most successful performers devote 50-60 hrs. per week on activities related to the craft. But, multiple daily practice sessions of limited duration are most effective. Research has shown that “practice in the brain” actually is as worthwhile as physical practice once we have established and know in vivid detail what we need to do. I would caution that “brain practice” really isn’t a substitute for physical practice, rather, it is worthwhile in addition to physical practice. Physical motion established can be reinforced just by imagining it.
