Tennis serves versus baseball pitch: similarities and differences

Typical gestures of tennis and baseball, as well as of all the so-called "overhead" sports (those activities, that is, which involve raising the arm above the head), have some kinematic aspects in common, but different kinetics. In other words, the movement of the upper limb is quite similar, but the forces involved and the musculoskeletal stresses differ significantly with implications that can affect the whole body.
