Exam 2: Resistance Flashcards
How is multi-angle isometrics performed?
Either manually or mechanically at multiple angles within available ROM
When is multi-angle isometrics performed?
When the goal is increased strength throughout range when joint ROM is permissible but dynamic exercise is painful or inadvisable
What are some indications to use isometric exercise?
- Prevent muscle atrophy 2. activate muscles and re-establish neuromuscular control 3. develop postural/joint stability 4. Improve strength when movement causes pain 5. develop static muscle strength at specific points during ROM
Fill in Blank in regards to isometric exercise intensity: _____ duration: _____ repetitions: _____
intensity varies duration should be 6-10 seconds repetitions: “good for increasing effectiveness”
Gains in muscle strength occur very (far/near) training angle. __ - __ points in ROM is recommended to increase static strength only during isometric exercise
near; 4-6
What are the precautions of isometric exercise
contractions should be gradual, make sure the patient is controlling their breath and not holding it in
What are the contraindications of isometric exercise
high intensity isometrics may be bad for patients with a history of cardiac or vascular disorder
a _____ muscle contraction causes joint movement and excursion of a body segment as the muscle contracts and shortens or lengthens under tension
dynamic
_____ contraction is a physical shortening of the muscle against a force
concentric
_____ contraction is a physical lengthening of the muscle as it attempts to control a load
eccentric
What is the rational for the use of dynamic exercise
most daily tasks involve concentric and eccentric movements so doing dynamic exercise makes therapy more functional
(concentric/eccentric) exercise recruits a larger number of muscle units to control the same load as compared to an (concentric/eccentric) contraction
concentric; eccentric
(concentric/eccentric) exercise can be done with larger loads, however at the end of an exercise program the strength gains appear to be similar to (concentric/eccentric)
eccentric; concentric
True or False: Concentric exercise tends to cause greater delayed-onset muscle soreness
false, eccentric does
Which type of resistance training is “a mainstay of resistance programs”
DCER
What does DCER stand for
dynamic constant external resistance exercise
which type of resistance training occurs when a limb moves through a ROM against a constant external load, provided by free weights, weight machines, or pulley systems
DCER
DCER requires both concentric and eccentric contractions to control the load and is used instead of “______”
isotonic
What is a limitation of DCER
the muscle is challenged maximally at only one point in the ROM
Which type of resistance exercise is a form of dynamic exercise in which the velocity of muscle shortening or lengthening and angular limb velocity is predetermined and held constant by a rate limiting device known as an isokinetic dynamometer
isokinetic exercise
isokinetic exercise is a form of ______ exercise
dynamic
Isokinetic exercise has a _______ carry-over to function
questionable
_____ exercise is completely unrestricted movement is space of a peripheral segment of the body
open chain
______ exercise occurs when a terminal segment is fixed and the encountered resistance moves the proximal segment over the stationary distal segment
closed chain
True or False: The action of the muscles when the distal segment is in contact with the ground (closed chain) or free to move (open chain)
true
What are some characteristics of open chain exercise
independent joint movement the body segment movement is distal to the moving joint muscle activation in the prime mover Performed in NWB positions external stabilization is usually required
What are some characteristics of closed chain exercises
interdependent joint movements body segment moving can be proximal or distal to the moving joint muscle activation in multiple muscle group Performed in WB positions uses axial loading
(open/closed) chain exercises are better at improving muscle performance of a specific muscle or group
open chain
in (early/late) phases of rehab the choice of open chain exercises allow for more control than closed chain
early
(open/closed) chain exercises are thought to promote dynamic stability
closed chain
(open/closed) chain exercises are better for instabilities
closed chain
(open/closed) chain exercises is best for improved balance and postural control
closed chain
What are the parameters of closed chain exercises
% body weight base of support support surface balance excursion of limb movement plane or direction of movement speed of movement or directional changes
What is the progression of the parameter “% Body Weight” for closed chain exercises
partial -> full WB
What is the progression of the parameter “base of support” for closed chain exercises
wide -> narrow bilateral -> unilateral fixed surface -> movable surface ->
What is the progression of the parameter “support surface” for closed chain exercises
stable -> unstable/moving Height: ground level -> low step, medium stem, high step
What is the progression of the parameter “balance” for closed chain exercises
with external support -> no external support eyes open -> eyes closed
What is the progression of the parameter “excursion of limb movement” for closed chain exercises
small range -> large range short arc -> full arc
What is the progression of the parameter “plane or direction of movement” for closed chain exercises
uniplanar -> multiplanar anterior -> posterior -> diagonal sagittal -> frontal or transverse

slow -> fast
A warm-up for resistance training should use (heavy/light) repetitive movement (with/without) resistance to the specific area to be worked
