Communication with the coach!
Communication with the coach! Waterproof EARPHONE. I want to suggest to make a waterproof earphone that can be inserted during the voyage to the ear, the swimmer will hear a coach. Also, the coach will be able to tell him a job or to improve your swimming technique to say error and it and the athlete would be able to correct their mistakes. Thus, we will achieve great results in swimming as in swimming very often make mistakes but do not know what think that all is well but actually make serious mistakes
Also it would help athletes Stiram at distances of 400 to 800 and a half thousand meters .the coach would help the athlete to put force On the course! the athlete would be told how much is left until the end of the race and when he can put all his strength !!! and if the athlete would be going for the world record or his Record he would have talked about it thus the athlete would be Courage, desire, adrenaline, and the sportsman would open in Second wind and the Will to win! this is very important when at the end of the race, the athlete is without any force and when it seems that everything is bad, the coach could motivate the athlete.
