Probably one of the most commonly used (and abused) methods of performance-enhancement for sprinters and indeed all running and jumping athletes is “plyometrics.” Plyometrics can be defined as movements that involve fast eccentric muscle actions followed by dynamic and explosive concentric actions (aka, the stretch-shortening cycle). The best example of a plyometric drill that comes to mind is the classic “depth jump” exercise where an athlete drops off a box or step of some pre-determined height. Upon hitting the floor the athlete concentrates on explosively jumping into the air as high as possible. The purpose of this method is to “shock” the body and nervous system to produce higher levels of muscle tension and force than would normally be possible without the preceding drop. In fact, the “father” and creator of modern day plyometrics, Yuri Verkoshansky of Russia, originally named the plyometric method the “shock” method. To understand how such a system of exercises could be beneficial or detrimental to sprinting, jumping, and indeed all athletes, let’s take a closer look at basic muscle function during movement.
1) In your eBook, you suggest that people considering barefoot running should begin by going straight to barefoot running as opposed to purchasing a minimalist running shoe. What is the primary argument for this approach? There have been some experiments which have shown that even the slightest bit of padding or material between the bottom … Read more
