Wrestling was a sport in which the participants attempted to grapple, throw, or immobilize each other.
While Jean-Luc Picard was a cadet at Starfleet Academy, he once wrestled a Ligonian wrestler, who he caught "with a reverse body lift and pinned him down in the first fourteen seconds of the match", according to gardener Boothby, who was very much surprised by the feat at the time. Picard stated that it "was all in the legs, from all the running [he] used to do." (TNG: "The First Duty")
Benjamin Sisko was particularly adept at the sport and was the captain of Starfleet Academy's wrestling team when he was a cadet. He once challenged his Vulcan classmate Solok to a wrestling match, but was defeated due to Solok's Vulcan strength, his anger towards him and his inebriation.
