Work =

Force x distance/time

Origin of plyometrics

- Early publications in Russia (later 60s/eearly 70s)
- shock training was translated to plyometrics by Micheal Yessis and Fred Wilt in 1980s (America)

Plyometrics definition

- Latin origin


- Plio (more) + metric (measures) = plyometrics (measurable increases)

Plyometrics and muscle activity

- max amount of tension in a muscle in the shortest amount of time


- muscles possess ability to impart dynamic activity to the body (store and release energy to allow for powerful movement)

Stretch shortening cycle (SSC)

- employs both the energy storage of the series elastic component (mechanical) and stimulation of the stretch reflex (neurophysiological) to facilitate maximal increase in muscle recruitment over a minimal amount of time.

3 phases of stretch shortening cycle

- Eccentric


- Amorization
- Contraction

__________ is vital to muscle recruitment and activity resulting from the SSC

A fast rate of musculotendinous

A - Eccentric
B - Amorization
C - Concentric

Mechanical Model

- Elastic energy in musculotendinous units are increased with a rapid stretch (eccentric muscle action) and then briefly stored
- If a concentric muscle action follows immediately, the stored energy is released, contributing to the total force production

What happens if a concentric muscle action does not immediately follow the eccentric muscle action?

- The stored energy is released as heat

Series elastic component (SEC)

- When stretched, stores elastic energy that increases the force produced

Contractile component (CC) [i.e., actin, myosin, and crossbridges]

- The primary source of muscle force during concentric muscle action

Parallel elastic component (PEC) [i.e., epimysium, perimysium, endomysium, and sarcolemma)

- Exerts a passive force with unstimulated muscle stretch

Mechanical model diagram

Neurophysiological model

- Potentiation of the concentric muscle action by use of the stretch reflex

Potentiation

- Change in force-velocity characteristics of the muscle's contractile components caused by stretch

Stretch reflex

- The body's involuntary response to an external stimulus that stretches the muscle


How is the stretch reflex stimulated?

- Due to muscle spindles being stimulated

What happens when the stretch reflex is stimulated?

- Sends input to the spinal cord via Type Ia afferent nerve fibres

What causes a reflexive muscle action?

- Type Ia afferent nerve fibres synapse with the alpha motor neurons in the spinal cord
- Impulses travel to agonist extrafusal fibres

How does the neurophysiological model dampen GTO inhibition?

- Spindles are faster than the GTO in response

Neurophysiological model diagram

3. If the athlete successfully executes this task, he or shemay move to a higher box. The box height should beincreased in 6-inch increments. Step 2 is repeated untilthe athlete fails to reach the standing jump-and-reachheight. This then becomes the athlete’s maximum heightfor depth jumps.


4. If the athlete cannot reach the standing jump-andreachheight from an 18-inch box, either the height of thebox should be lowered

THR (target heart rate) = (HRR x Ex Int) + RHR

HR calculations (% of max HR method)

THR = APMHR x Ex Int
