After it is thrown, speeds can reach up to 80km/h. Slow twitch motor units consists of mainly type 1 (slow twitch) muscle fibers and have fairly slow nerve transmission speeds and small muscle forces. Throwing techniques have changed from a linear movement to an arc. Throwing distances are based on three variables: throw, angle of release and velocity. Two components, speed and power, are required for improved performance. Power requires the most force in the shortest amount of time. Movement 1: Throwing a Spiral. The movement involves chaining segmental movements such that the last segment is free to move E.g. All of the below practices should include each of these principles and coaching points, with some points more emphasised throughout the analysisthan others depending on the session.
