Kick Serve

Also known as: saque con efecto, topspin serve padel

Definition

A Kick Serve in padel is an underarm serve struck with topspin so that after bouncing in the service box it accelerates and kicks up or to the side. This makes the return more awkward than a flat serve.

Because padel serves must be delivered underarm below waist height, generating topspin requires a distinct low-to-high brushing action. The ball bounces predictably off the surface and then accelerates, rising into the receiver's body or jumping away from the backhand. The difficulty for the receiver is a bounce faster and higher than a flat delivery — especially uncomfortable on indoor courts. It is an advanced skill, because generating topspin from an underarm action is mechanically demanding. Most club players stay flat or sliced; this is a differentiator at intermediate-to-advanced level.

Beginner tip

Practise the motion without a ball first — swing upward at the same point and feel the forearm brushing skyward — then add the ball once the low-to-high motion feels natural and repeatable.

Advanced note

Aim at the receiver's hip on their dominant side rather than the backhand — jamming the forehand is often harder to handle. This is because receivers instinctively step back from a shoulder-high ball on that wing.

Example

Brushing steeply up through the ball from a low toss, the server sends one that bounces and rises sharply into the receiver's shoulder on the backhand side — forcing a cramped, defensive return.

Why it matters

It adds a weapon opponents cannot simply step into. Motion Lab estimates how steeply your swing path rises. This hints at topspin. It does not see spin. As a result, confirm the kick after the bounce on video.

How it shows up on video

On video it shows a low-to-high brushing path through the underarm delivery — the racket head rises steeply through the ball at contact. After the bounce in the service box, watch the ball's trajectory: a successful one accelerates and rises into the receiver's body rather than staying low. Also check the receiver's footwork: if they are moving backward after the bounce, it is working.

Common mistakes

Making contact too far in front of the body on the underarm swing, flattening it into a slow, high-bouncing ball that receivers step into easily.
Not generating enough swing speed on the brush, producing minimal rotation and a ball that sits up without acceleration.
Aiming at the T, where the bounce stays central. The shot is most effective into the body or the wide corner where the acceleration catches receivers off-guard.
Attempting it as a first delivery in a casual club match and double-faulting while still learning the rotation, losing confidence under pressure.

In SwingVantage Motion Lab

Motion Lab estimates your swing path from your arm. It does not track the ball, so check its kick after the bounce on video. A contact angle above 40 degrees from horizontal on the underarm swing, combined with ball acceleration after the bounce, is the kinematic signature of the shot.
