how to speed up stroke
In any swimming competition, it is obvious that quicker arm stroke motion will enable swimmers to swim faster, but for certain swimmers, no matter how we remind them to speed up their arm motion, they are still unable to do so.
My questions are:
a) why so? Is it because they lack arm strength which allow them to push faster in the water and swing faster above the water?
b) how to correct this shortfall? Can we train them to increase their stroke count?
c) for my son when swims backstroke, he always pauses before entering water and pauses again before he starts pushing the water forwards. How to overcome this bad habit?
