Technical Skills and Stroke Mechanics Flashcards

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

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

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.

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

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

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.

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

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

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.

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

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

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.

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

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

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.

In ITF coaching terminology, what does 'unit turn' refer to in the context of groundstroke preparation?

Answer: The coordinated rotation of the shoulders and hips together to prepare for a groundstroke

A unit turn is the simultaneous rotation of both the shoulders and hips as a single unit to prepare for a groundstroke, enabling early racket preparation and improved body rotation through the shot.

Which of the following best describes the 'windshield wiper' follow-through on a modern forehand?

Answer: The racket sweeps across the body from low to high and then rolls over, finishing beside the player's right hip for a right-hander

The windshield wiper follow-through involves the racket brushing steeply upward through contact and then rolling over, finishing beside the dominant hip, which maximizes topspin and helps the player control the ball's trajectory.
