When we swim we hope that the movements we make are as close as possible to the motor project we had in mind just before we started.
How close these movements are to how we imagined them reflects are coordination skills in the water.
These skills come on two levels: general and special.
While the former concern the movements themselves from the learning process to full control of our motion, the latter are connected with our abilities and, hence, the possibility of performing these movements at a certain rhythm, in a certain position (balance), in response to a certain signal, realising what degree of intensity of action our muscles are undergoing and for how long they must/will have to keep it up.
If, while you are swimming, you notice that your arm is entering the water “with a low elbow”, it will be your coordination skills that allow you to correct this mistake.
If you want to improve your start, swim stroke or turn, you will always have to rely on these skills, which, obviously, are just as important as your physical attributes (strength, stamina, speed).
The best age to improve your coordination ranges from 7-13/15 years, but do not despair, there is no specific age limit that will prevent you from improving them if you perform good drills…
