Perfectly

What are the components of stretch-induced strength loss

Neurological: suppressed NS because not doing anything related to task

Mechanical: stretching tissues and actin/myosin pulled out and require more time to return

More pronounced in slow velocity activities

Perfectly

When should you avoid stretching

During DOMS

Post high-intensity sessions or after strengthening sessions

Perfectly

Active dynamic stretching technique

Movement through full range
Start slow and increase in speed
Good for warm up

Perfectly

PNF?

Proprioceptive neuromusclular facilitation

Concept of patient management of working on total human not just one problem. Focuses on untapped patient potential and reinforces what patient can do

Move at patient pace

Increase ability to move and remain stable and guide coordinated movement thought timing and increase stamina

Facilitation

Motor control
Increases excitability to the target muscle

Way to restore dysfunctional muscle

Perfectly

Inhibition

Motor control
Decrease excitability or motor units

Reduce spasticity

How well did you know this?

Perfectly

What techniques utilize reciprocal inhibition/sheringtons law?

1.CRAC
Contract, relax, agonist contract

Ex: biceps contract, triceps inhibited

Perfectly

What is postcontraction inhibition

After muscle is contracted it is automatically in a relaxed state for a latent period.

And during that relaxation time you can stretch it

Perfectly

What techniques utilize the postcontraction inhibition technique

Hold relax
Postisometric relaxation (PIR)
Postfascilitation stretch

Perfectly

Rhythmic stabilization

Maintained when COG remains over the base of support

Balance

1st class lever

Force, fulcrum, resistance

Cervical extension is what kind of lever

1st

Example of 1st class lever

Cervical extension Seesaw Scissors Crowbar

2nd class lever

Fulcrum, resistance, force

Example of 2nd class lever

Wheelbarrow Stapler Calf raise Push-up

Calf raise is what lever

Push up is what lever

3rd class lever

Fulcrum, Force, Resistance

Examples of 3rd class lever

Elbow and knee flexion Baseball swing Tongs Shoveling

Mc lever

Advantage of 3rd elver

Produces speed

Longer moment arm....and torque

Increased torque

How can you change the length of the moment arm?

Chance where resistance is placed

Z line

Separates sarcomere

H zone

Center of sarcomere

M line

Myosin filaments anchor eachother

A bands

Myosin align

I band

Actin

Force of contraction depends on what

``` Number of motor units Number of fibers per unit Length of muscle Direction of motion Speed of contraction ```

Isometric exercises are good for where

Muscles that stabilize the spine

Concentric contractions use for what

Accelerations

Eccentric contractions used for what

Shock absorption | Created increased torque

What contraction causes DOMS

Eccentric

What is the SAID principle

Specific Adaptation (to) Imposed Demands

Progressive overload

Continual gains require increasing loads

FITT principle

Frequency Intensity Time Type

Strength

``` Low repetitions (3-9) High intensity (90% RM) ```

Endurance

``` High repetitions (15-20) Low intensity (70% RM) ```

Initial strength gains when and due to what

``` 3-6 weeks Neural factors (better coordination) ```

Neural factors involved in increased muscle in first 6 weeks

Faster rate of motor unit recruitment Greater # and selection Proprioceptors : detect stretch and contract faster GTOs: detect tension and cause relaxation usually....GTO inhibition in agonist and activation in antagonist to decrease risk of tear

Rhythmic stabilization

Alternating between isometric actions of agonist and antagonist muscles

Alternating between isometric actions of the agonist and antagonist muscles

Rhythmic contraction | Facilitate—strengthen

Shake weights are a type of what

Rhythmic stabilization

Concentric action of antagonist followed by a concentric action of agonist

Slow reversal

Concentric action of antagonist, then concentric action of agonist

Hold relax

Isometric action of antagonist Followed by relaxation Passive stretch of antagonist

Isometric contraction of antagonist, followed by relaxation then passive stretch of antagonist

Hold relax

What is hold relax done for?

Inhibit—increase ROM

Maximal concentric action of antagonist against resistance followed by relaxation and them movement into limited ROM

Contract relax

Max concentric action of antagonist against resistance followed by relaxation then movement into limited ROM

Utilizes reciprocal inhibition by having the agonist contract while stretching the antagonist

Contract relax agonist contract

Uses reciprocal inhibition by having agonist contract while stretching antagonist Max concentric contraction of antagonist followed by relaxation then contraction of agonist while stretching antagonist into limited ROM

Speed of concentric and eccentric to create most force

Max force with slow concentric and fast eccentric

Strength

Muscles ability to produce tension and resultant force
