Over the next couple days, we'll break down the most common running errors. Today with propably the most common fault called the "Heelstriker"
The most common faults we see with the heelstrikers are:
1) Poor body position - bent at the waist. The athlete has lost the hips behind, creating a "K" shape in the body.
2) Landing in front - creating a lot of impact on the knees, hips and the spine
3) Landing on heel - no muscle elasticity
4) Landing on straight leg - overloading the knee
5) Pushing off in back - no use of gravity (working against gravity not taking advantage of it)
6) Low cadence and over striding - foot on the ground for too long
7) A lot of vertical movement - wasted energy as the athlete is trying to move forward and not up
What causes the heelstriking? Ofcourse there are several reasons why a person moves as they do, but a few of the most obvious reasons are: wearing cushioned shoes (barefeet don't allow heel landing) and so called "walking running". The walking running we use for to define a movement that is caused by the loss of the natural running movement pattern and so replaced by something that our body knows how to do: walking with an added hop.
A human is a heelstriker when he walks, not when he runs.
