The Wrist Snap during the service motion. The wrist "snap", or rather the flexion of the wrist during the service motion, is a very debated and often misinterpreted topic in tennis.
Brian Gordon's "The Serve and Tennis Science" clearly shows the % contribution of wrist movement on a serve, a.k.a. extension, deviation, flexion. The numbers show the wrist contributes second in global usage only to the twisting of the trunk, yet ahead of elbow extension, shoulder movement, upper arm twist and forearm pronation.
The typically held view from most tennis coaches is that the wrist snap on the serve involves taking the wrist from a position of extension, and ‘snapping’ it to a position of flexion as we hit the ball.
For many moons I have heard the term "snap your wrist" on the serve. I don't recall being told this by a coach as a youngster but have certainly heard many a pro player mention "wrist snap" when describing how they get pop on their serve. You might have heard others say that one should […]
At ball contact, ball velocity is determined by shoulder internal rotation and wrist flexion.25,26Elbow flexion (20° ± 4°), wrist extension (15° ± 8°), and front knee flexion (24° ± 14°) are minimal at contact.29Trunk is tilted 48° ± 7° above horizontal in Olympic professional tennis players.29.

I see many pros flex their wrists inward (i.e., palmar flexion) when they set up for serves. I see Djokovic constantly do that, and I also remember Lindsay Davenport's pronounced palmar flexion of her wrist. How does palmar flexion of the wrist at the beginning of your serving motion help...
The ball is rapidly thrown using only a wrist flexion motion (the elbow remains fixed in approximately 90° of elbow flexion) toward the ground whereby the player catches the ball and quickly returns it back to the floor using a snapping type motion.
The tennis serve is one of the most complex movements in regards to mechanics. With the amount of force required to generate power from the ground up, it is truly a movement that requires the full kinetic chain. Depending on what research you read, the tennis serve is broken down into approximately 8 stages. Stage 1- Body Positioning: The idea ...
