“Biomechanics of a Lacrosse Shot” Lacrosse is defined as a ball game invented by American Indians, now played by two teams who try to propel a ball into each other's goal by means of long-handled hooked sticks that are loosely strung with a kind of netted pouch (Farlex, Inc.). Behind every shot taken in a lacrosse game, elements of biomechanics are implemented. Biomechanics is the “sport science” field that applies the laws of mechanics (movements, body angles, joint positions, etc.), biomedical engineering, and physics (gravity, forces, velocities, etc.) to athletic performance (What is 3D Biomechanics).
Ben Shear “is a frequent presenter and writer on various topics related to athletic performance, including a presentation on

The magnitude of your acceleration is large and your velocity changes rapidly” (Bloomfield, 6). Direction for the player’s acceleration is key. Since the intentions of a lacrosse player are to move forward towards to goal, the direction is clearly stated and accomplished.
After achieving the correct forward acceleration, we come down to the final link, the shot. The elements needed to complete a successful shot are the movements of the arms and the shooter’s wrist snap. A player must extend their stick away from their body in order to maintain the correct stance to produce the most accurate angle/s to shoot. “The longer the lever arm, the less force it takes to cause a particular angular acceleration” (Bloomfield, 53). For a player to achieve torque when attempting to complete a lacrosse shot, he must push down in a perpendicular motion away from the axis (hips). If a player is holding the stick in the correct way, he will be following the “right-hand rule.” In other words, “if you point your right index finger in the direction of the lever arm and your bent middle finger in the direction of the force, then your thumb will point in the direction of the torque (Bloomfield, 55). This allows the shot to fly straight forward into the back of the net with high velocity.
However, shooting the ball forward, with no changing angles ,is not always the best option; the goalie will
