Velocity

Velocity was a one-on-one competitive sport that was a cross between handball and a phaser range and held on a holodeck. Each player must avoid being hit by a disk by shooting it and sending it back toward their opponent. It was fast-paced game of wit and physical endurance, with both players in constant motion, ducking and spinning.

The disk used in the sport was holographically created, and was described as an aerodynamic, metallic object, eight inches across, glowing different colors when hit by each competitor's hand phaser – usually from red to blue, corresponding with the competitors' assigned colors. The game was played in rounds, and was concluded when a player achieves a "full impact" of the disk with his/her opponent's body.

Ensign Harry Kim was the captain of his Velocity team at Starfleet Academy. 

Captain Janeway and Seven of Nine played a ten round game of Velocity in late 2374. Janeway won, six to four. 

When Janeway secluded herself from the crew of the USS Voyager while crossing the Void in 2375, Chakotay asked her to join him for a few rounds of Velocity on the holodeck.
