The swimming Teacher said not crawl with feet
When we try to swim fast, what will you do? People who can swim at a constant speed, the kick is minimal.
When the resistance of the water on the body, the speed of swimming will increase as the foot speed increases at a speed of 1.1 m / sec, while the movement of the foot will disturb the flow of water, if it exceeds 1.3 m per second.
With some practicing, it means that fast people can swim more quickly without kicking the legs. I do not think it will be effective because I can not swim so fast anyway, but like to try it for a moment.
If you see it in the pool it might call out.
