Exercise for Performance Initiation Flashcards
What is the first step in exercise pescription?
determining what type of exercise your patient needs?
What five broad categories are exercises broken up into (exercise framework)?
- Tissue Healing
- Mobility
- Performance Initiation and Stabilization
- Performance Improvement
- Advanced Skill
T/F: you need to complete tissue healing before entering into exercises for mobility.
False - categories just follow progression
If a patient comes to you with tissues already out of the inflammatory phase, no pain, and full mobility, what category of exercise framework should you start with?
Not necessary to start with tissue healing exercises, can jump right into initiation, stabilization, and motor control exercises.
What is the criteria for initiation exercises?
- Little to no signs of inflammation or stabilized inflammation
- Little to no pain or stabilized pain
- Mobility
What are the signs of inflammation that most of it not all should be gone?
Pain, edema, redness, and heat.
At what phase is the tissue in?
should be into the proliferative and remodeling phases.
If signs of inflammation linger, especially pain and edema, what should happen as you progress into performance initiation exercises?
they should be decreasing and continue to decrease
T/F: While with exercises for mobility and pain edema should not increase, it might for initiation of exercises.
False: edema should not increase with your exercises. If it does, that is telling you that you are causing trauma to the tissue and re-initiating the inflammatory process.
If you are seeing signs of increased inflammation with initiation of exercises, what would this be an indication of?
That you need to back off on the exercises for mobility and return to exercises to promote tissue healing.
At what level of mobility should patients be at before initiating performance exercises?
It would be great if they had full, pain free, normal mobility, but this may not be the case.
However, patients should have a pain free range through which they can move. If they do not, exercises for mobility would be more appropriate.
What is involved in muscle initiation?
- Neural Input
- Vascular regulation
- Metabolic responses
- Muscle contractility
How does a muscle contract (sliding filament theory)?
muscle fibers shorten or lengthen because thick and thin myofilamts slide past each other.
What starts starts the sliding filament theory?
action potential
What is excitation contraction coupling?
The sequence of events by which transmission of an action potential along the sarcolemma leads to sliding of myofilaments.
What is the firs step in excitation-on
An action potential propagates along the sarcolemma and down the T-tubules.
What is the 2nd step of excitation coupling?
Transmission of the action potential past the triad regions causes the sarcoplasmic reticulum to release calcium ions into the cell, making calcium available to the myofilaments.
What is the 3rd step of excitation coupling?
Calcium ions bind to troponin, causing troponin to change shape and remove the blocking action of tropomyosin on actin.
What is the 4th step of excitation coupling?
Myosin cross bridges attach and pull actin toward the center of the sarcomere.
What is the 5th step of excitation coupling?
Breakdown of ATP via ATPase supplies energy for rotation of myosin head resulting in muscle contraction.
What is the 6th step of excitation coupling?
When intracellular levels of calcium are too low for contraction, tropomyosin blockade is reestablished and ATPases are inhibited. Cross bridge activity ends and relaxation occurs.
Why do we want exercises that cause muscle contraction?
- Load Tissues
- Proper recruitment of muscles: synergists and stabilizers
- Increase cardiovascular and muscle endurance
- Increase muscle effective acceleration and deceleration responses (motor control at end ranges)
- Demonstrate muscle control during functional activities
