CH 18

Question 1

The stretch shortening cycle

Answer 1

is when there is an eccentric contraction which stores energy and then releases during the concentric contraction to then make it more powerful and explosive.

Question 2

The eccentric phase

Answer 2

is when there is preloading or stretching of the agonist muscles. The energy from this is going to be stored, and muscle spindles are then stimulated, which sends the signal to the nervous system.

Question 3

The amortization phase

Answer 3

is referred to as the transition period or phase, which is the time between eccentric and concentric. This is the electromechanical delay that can exist in this process.

Question 4

The concentric phase

Answer 4

is the response to the other two phases before, and this has the force being produced to contract and shorten the muscle. When this is done, the concentric phase will be more powerful.
