Jump Shot Effect on Basketball: Does It Help?

[Macroer]

Hi,
I was wondering if the act of jumping itself has an effect on the ball as it is released out of the players hands(ex. momentum etc.). I know that the increased height decreases the chance of the ball from being blocked, but i was wondering if it does more than that.
Thank You

Jump shot uses also your legs, instead of just arms, to accelerate the ball. This allows the arms to work less but more accurately, and just do the "fine tuning".
