Q

eccentric phase of plyometric training

A

deceleration, loading, yielding, counter movement, cocking

increases muscle spindle activity

potential energy is stored in elastic components like stretching a rubber band

Q

amortization phase

A

dynamic stabilization

time between end of eccentric muscle action and initiation of concentric contraction

transition phase

prolonged amortization phase = less than optimal

Q

plyometric strength description

A

more dynamic eccentric and concentric movement through a full range of motion

specificity, speed, and neural demand may also be progressed

improve dynamic joint stabilization, eccentric strength, rate of force production, neuromuscular efficient of entire human movement system

repetitive fashion

Q

ice skaters

A

plyometric-power phase

stand with feet shoulders-width apart and pointed straight ahead

quickly push from side to side, landing on opposite foot while maintaining optimal alignment during the side to side hopping movement

repeat as quickly as can be controlled

can start by hopping side to side from one foot to other as fast as possible then progress by adding reach with opposite hand
