ITF Technical Skills and Stroke Mechanics 2

Question 1

Which phase of the serve motion is commonly referred to as the 'back-scratch position'?

Accepted Answer

The racket drop behind the player's back before the upswing

Answer

The back-scratch position describes the moment when the racket drops behind the player's back and the elbow points upward, creating maximum shoulder rotation before the upward swing to contact.

Question 2

What is the primary biomechanical advantage of using a looped backswing on a forehand groundstroke?

Accepted Answer

It generates racket-head speed through momentum built in the loop

Answer

A looped backswing builds racket-head speed through the continuous circular momentum of the swing, allowing players to generate more power with less muscular effort than an abrupt straight backswing.

Question 3

In ITF coaching, what is the key technical difference between a slice backhand and a topspin backhand?

Accepted Answer

Slice uses an open racket face moving downward through the ball; topspin uses a closed face moving upward

Answer

A slice backhand is produced by swinging with an open racket face downward and through the ball, imparting backspin, while a topspin backhand uses a closed or neutral face moving upward to brush the back of the ball.

Question 4

When coaching a player on the overhead smash, the ITF recommends orienting the body in what way relative to the incoming ball?

Accepted Answer

Sideways to the net with the non-dominant shoulder pointing toward it

Answer

Turning sideways with the non-dominant shoulder toward the net allows the player to prepare a full shoulder turn, track the ball above and slightly in front of them, and produce maximum power similar to the serve motion.

Question 5

What is the purpose of 'pronation' in the service motion according to ITF technical coaching?

Accepted Answer

To rotate the forearm so the racket face moves from edge-on to flat at contact, accelerating racket-head speed

Answer

Forearm pronation during the serve rotates the racket face from edge-on to flat (or past flat), dramatically accelerating the racket head through the contact zone and is the primary source of speed in the serve.
