All in coordination
When you train a particular body area, what exactly adapts to make an improvement? One interesting source of insight into these questions comes from studies where they train just one limb and then see whether the performance of the untrained limb changes in some way.
What are your physical limits? What is your body capable of? How fast, how far, how strong, how long? In all likelihood you will never know, because your brain will probably never let your body reach its real limit. And that’s a good thing, because that will help prevent you from breaking bones, straining muscles, dislocating joints and maybe even killing yourself...
The other morning I was taking a walk with my one year old daughter strapped to my chest. She was facing me and I had my hands around her low back. When she is not fast asleep she likes to look around to check out what’s going on in the hood. One of the things I have noticed about babies is that a huge percentage of their movements in the first year . . .
In sports, one of the most important (and completely overlooked) keys to performance is the processing of visual information. I just came across a study that helps demonstrate this point in an interesting way.
