Answer 1

Tennis biomechanics is a very complex task. Consider hitting a tennis ball. First, the athlete needs to see the ball coming off their opponent's racket. Then, in order, they have to judge the speed, spin, trajectory and, most importantly, the direction of the tennis ball. The player then needs to adjust their body position quickly to move around the ball. As the player prepares to hit the ball the body is in motion, the ball is moving both in a linear and rotation direction if there is spin on the ball, and the racquet is also in motion. The player must coordinate all these movements in approximately a half a second so they strike the ball as close to the center of the racket in order to produce the desired spin, speed and direction for return of the ball. A mistake in any of these movements can create an error.
