Overview
The hammer throw is a track and field throwing event in which the athlete spins with a metal ball (the hammer) attached by wire to a handle, building angular velocity through several turns in a circle before releasing the hammer forward and upward. The thrower typically begins with one or two preliminary swings, then enters the circle and executes three or four full rotations (turns) while maintaining a low center of mass and driving the hammer in an accelerating path. Release occurs with both feet in contact with the circle; the angle and height of release, together with release speed, determine the distance. Key biomechanical factors include rotational speed and timing of the turns, trunk and shoulder sequencing relative to the lower body, double-support vs single-support phases, and release angle and velocity. Biomechanical analysis of the hammer throw can address turn rhythm and speed progression, body position and lean during rotation, timing of release, and release parameters (angle, height, velocity).Dimensions
Required inputs for processing are not yet defined. When supported, typical dimensions may include:- handedness or rotation direction: the direction of rotation in the circle [‘left’, ‘right’], if applicable
