Lacrosse is a team sport played using a small rubber ball (62.7-64.77 mm, 140-147 g) and a long-handled stick called a crosse or lacrosse stick. It is often played as a contact sport. The head of the lacrosse stick is strung with loose mesh designed to catch and hold the lacrosse ball. Offensively, the objective of the game is to score by shooting the ball into an opponent’s goal, using the lacrosse stick to catch, cradle, and pass the ball to do so. Defensively, the objective is to keep the opposing team from scoring and to gain the ball through the use of stick checking and body contact or positioning. The sport has four major types: men’s field lacrosse, women’s lacrosse, box lacrosse and intercrosse. The sport consists of four positions: midfield, attack, defense, and goalie.
