The term "body checking" is associated with hockey, where players use their bodies to impede an opponent's movement. This technique is used strategically to gain possession of the puck and is a fundamental aspect of the game, helping to maintain both physical and tactical play. Body checking can range from light contact to more forceful maneuvers, depending on the rules and the level of play. It requires skill, timing, and an understanding of the game to execute effectively without causing penalties.
