Although the predominant focus of this blog is Budo Karate, I am going to post some articles about proper movement and conditioning of the body. You may wonder why I would post such articles on this blog, but before you question, allow me to explain. While karate to me is primarily about Budo, a martial art, I believe that the better we can understand how the body is designed, the more effective our karate can be. Moreover, one must concede that for many people, karate is a means of remaining healthy and functional through old age; therefore, we want to train karate according to the principles of functional biomechanics in order to perform better and free of injury. As a result of the aforementioned reasons, I have studied the science of functional movement for the past years. I have discovered and continued to discover that sports science findings run in accordance with orally transmitted karate principles.
The 3 hamstrings are responsible for decelerating the knee as we rotate and change directions; the hamstrings also control the torso and are driven by the torso.
As the hamstrings decelerate the knee in 3 planes they receive prorioceptive feedback from the golgi ligament endings in the collateral ligaments and in our training and conditioning we need to develop and make more accurate this sensory feedback. If sensory feedback is not accurate the hamstrings will react to gravity, momentum and the movement of other parts of the body late and not accurate.
Flexion of the knee in function is given by gravity as we walk or squat or prepare for a jump.
Even a head forward posture can cause the hamstring to become overactive because it constantly have to support a body with a center of gravity too much to the front.
When we train or rehabilitate on leg curl machine we are saying that proprioception is not important, the butt and the foot interaction with the hamstrings is not important, we do not consider the hamstrings interaction with its friends.. We do not consider that there are 3 hamstrings that function in the very important transverse and frontal planes as well.
Bad hamstrings are a result of something causing the hamstrings to become bad.
That is why we have to look at the whole and train the whole.
Training and conditioning need to concurrently deal with stability, mobility and proprioceptive reaction.
I f you do functional training the hamstrings will perform functionally, and sometimes even if one does not identify the cause functional training will solve the problem.
When you functionally train the hamstrings you automatically train the whole body functionally.
Functional training prepares one for the demands of functional activities.
In the traditional program return to activity was on average 37 days, in the functional 22 days.
Re-injury rate within first 2 weeks of activity in traditional program 50% versus 0% in functional.
Re-injury within one year 50% versus 5%.
