To get an insight into the process of recovery it is necessary to go a little bit into the physiology of muscle adaptation by training. There have been days when we were not having microscopes giving us a view on the micro-texture of this marvelous tissue. Back then people thought the muscle is not able adapt or recover. We had a similar idea about the muscle as we had not very long ago about neurones, either proved to be wrong! Why we could not observe muscle changes was because of the fact that the muscle differentiates and proliferates relatively slowly compared for example to the various connective tissues or mucosal linings.

Today we are well aware of the muscle structures, we know that a muscle is build out of bundles of fibers with different sizes whereas on the tiniest level of the filaments the processes of contraction are initiated. Contraction is a perfectly orchestrated course of events where biochemical actions are transferred into biomechanical movements. As a result myosin and actin filaments shrink against each other.

What happens within the muscle tissue during training? (more…)
