Question 1

Stretch shortening cycle

Answer 1

Active stretch (eccentric contraction) followed by an immediate shortening (concentric contraction) of the same muscle

Question 2

Plyometric training

Answer 2

Exercises involving an eccentric contraction immediately followed by an explosive concentric contraction

Question 3

Phases of plyometric exercises

Answer 3

Eccentric (loading phase), amortization (transition phase), and concentric (unloading phase)

Question 4

Eccentric phase

Answer 4

Pre-stretching muscle prior to activation; increases muscle spindle activity

Question 5

Amortization phase

Answer 5

Electrochemical delay in transition from eccentric to concentric muscle action

Question 6

Concentric phase

Answer 6

Concentric force production immediately after amortization phase
