When ball is coming to seasoned cricketer he draws his hand in backward direction during catching ball as shown in figure. There by the takes longer time to stop ball.
the novice on the other hand keeps his hands provide and tries to catch instantly . He need to prodive much greater impulse of force to stop ball instantly and can get hurt.
