II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
(6 pts).

A ballistic stretch will cause the stretched muscle to contract and not to relax.
II! II! II! II! II! II! II! II! II! II! II! II! II!
During a ballistic stretch, the muscle spindles, sensory organs that lie parallel to the muscle fibers,
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
perceive and then transmit the rate and length of the stretch to the CNS.
II! II! II! II! II! II! II! II! II! II! II! II! II! II!
The CNS the analyzes the info and sends a neural impulse to the muscle belly to contract, thereby
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
stopping the joint from continuing to move and the muscle to stretch further and risk injury.
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
The force of the contraction is determined by the force of the stretch, the greater the stretch the greater
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
the contraction.
II! II!
the entire process from stretch to muscle contraction is called the Myotatic Stretch Reflex.

2) Describe why ballistic stretching can be dangerous (4 pts).
II! II! II! II! II! II! II! II! II!
On the 2nd bounce is when injury can occur, since the muscle is being stretch in one direction while the
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
contraction of the muscle occurs in the opposite direction. Now, there are two opposing forces occurring
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
at the same time in both directions, causing increased tension on the muscle structure and increasing the
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
risk of injury.
