Kathryn Janeway played on her high school tennis team. In 2373, she decided to take up tennis again, after giving it up in 2354. Tuvok walked in on her, in her ready room, as she was practicing her serve, and was nearly hit by the ball. She then confessed that she was a bit rusty, after losing her first match in straight sets in a novice tournament on the holodeck. Tuvok suggested that she should "maintain eye contact with the ball at the apex of its trajectory", so that her "serve would be more effective". When asked by Janeway if he was a tennis player, he logically stated that it was "simple physics". (VOY: "Future's End")
