Whip throwing arm

Feedback Cue

• Rotation of hips immediately followed by the careful 'whipping' motion of throwing arm.

The final movement of the arm ends in a ‘whipping’ or slinging motion this allows the summation of force generated by the larger muscle groups to transfer to the ‘distal segments of the arm much like the transfer that occurs in a fishing rod’ (Blazevich, 2013, p. 186) The careful sequential pattern of the over arm throw allows the ‘joints [to] increase their velocity first and the more distal segments increase their velocity later. Once the bigger muscle groups reach their maximum range of movement the proximal segments of the arm halt and the angular momentum must be transferred to the more distal segments or else the velocity will decrease or be lost. (Blazevich, 2013, p. 187) Therefore, if we rotate the proximal segments of the arm and then halt them, the momentum is transferred to these lighter segments and so their velocity must increase which allows for the greatest transfer of momentum to the projectile.
