Pickleball vs. Tennis: Where the Biomechanics Overlap and Where They Don't

"Pickleball is just slow tennis." The biomechanics say otherwise. The strokes look similar because the kinematic templates are the same, but the rate of force development, the contact windows, and the kinetic-chain contributions differ in ways that matter for training.

Forehand: the 60% rule

A tennis forehand builds racket-head speed primarily through the kinetic chain (~60% from legs and trunk, ~40% arm). A pickleball forehand inverts this — closer to 40% trunk, 60% arm. Players who transition from tennis often over-rotate and "swing through" pickleball shots.

The serve looks the same but isn't

Pickleball serves are underhand and below the waist. That rule eliminates the shoulder's internal-rotation whip that makes a tennis serve explosive.

Kitchen volleys = tennis volleys, scaled

The one stroke where transfer is nearly perfect. Same punch volley mechanics: short backswing, compact follow-through, firm wrist.
