:-? I'm just curious......in the history of tennis instruction or sports science have there ever been attempts by coaches or sports scientists to calculate players optimum hitting zones in relation to the dimensions of the court ? In plain English, I mean for example, using mathematical analysis to work out how high I should toss the ball on my serve if I know I'm 183cms tall, the racket will extend about a further 70cms above my head at impact, and the opponent's service line is "x" metres/feet in front of me...where should I hit it to prevent it going long or into the net? Have any sports sci geeks ever used math to work out such methods to aid in player instruction ? I'm not a math or science person. It's just that if we are certain of some things - court dimensions, common players heights (mean/average height) etc, that we could calculate and extract a bit of extra certainty into what's a highly variable sport. I've probably forgot to mention force and velocity here - I'm sure physics plays a big part in any analysis as well. Any insights welcome, I've always wondered about this aspect of the game.
