What is Your Movement Style?

Panjabi divided the motor control system for the spine into three distinct subsystems –  passive, active and neural. I like applying this idea to the whole body, partly because I find it an interesting way to distinguish different strategies for movement and posture, based on preferential use of one subsystem over the others. The passive… Read More

Power at the End Range

In the previous post I discussed the idea that flexibility is generally overrated as a quality that promotes sports performance. In particular, I argued that: most sports do not involve extreme ranges of motion; most elite athletes in fact have only average flexibility; and quality of motion at a joint is usually far more important… Read More

More on Flexibility and Running Economy

I have previously posted about some studies addressing the relationship between flexibility and running economy. The studies find that less flexibility correlates with greater running economy. The reason is probably that that elastic recoil of muscle and tendon is an important contributor to running power. Just as a golf ball will bounce higher and longer than a squash ball, a stiff runner will Read More

Flexibility and Running Economy

Not yoga class In a previous post I argued that flexibility is often massively overrated as a desirable physical quality for sports performance. Nowhere is this point more clear than in the case of running economy, as shown by a few recent studies. Running economy basically means efficiency – a runner with better economy uses… Read More

The Central Nervous System

One of the most important things to understand about your body is that it is largely governed by the central nervous system (the “CNS”.)  The CNS is composed of your brain, the spinal cord and the nerves.  It is a lightning fast communication system that controls every aspect of your sensation and movement. The CNS… Read More
