Coordination is one of the most important thing to study in the world of sports and athletics. It is the quality wich enables the individual to integrate all the powers and capacities of his whole organism into an effective doing of an act. Before the movements, muscular tension on both side of the joints changes to be moved. The effectiveness of this “teamwork” is one of the factors wich determine limits of speed, endurance, power, agility and surely a lot of other things in all athletic performances.
The well-coordinated fighter does everything smoothly and gracefully. Muscles have no power to guide themselves, they depends on how the nervous system guides them. When a movement is well-executed, it means that the nervous system has been trained to the point where it sends impulses to certain muscles, causing these muscles to contract at the good fraction of a second.
Training “coordination” is purely a matter of forming proper connections in the nervous system throught practice. Each performance of an act strengthens the connections involved and makes the next performance easier. Do not practice skilled movements when you are tired. You will be doing wrong movements and your progress will step back.
