P.E Revision Biomechanical Principals-Levers

In the throwing activities, the distance achieved is directly related to the speed of the release. Generally, the longer a lever is, the faster the distal end of the object will move. For this reason, the farther a discus or hammer thrower can position the implement from the body (the axis of rotation) during the turns before the release, the greater the speed of release.

In Shot Put the bicep is the antagonist and the input of force the fulcrum is the elbow joint the load is at the end of the arm.The more extended the the atheltes arm and the higher the position of the athlete the more force and speed the shot put will gain.
