Term
The shape and arrangement of muscle fiber does or does not affect the muscles ability to relax
Definition
does NOT
Term
Essentric muscle action results from isometric muscle contractions true or false
Definition
false essentric is
controlled or resisted types of movements. like isotonic I guess.
Term
each muscle can be innervated by one or multiple nerves true / false
Definition
true
Term
Isokinetic muscle contraction involve a dynamic movement wherein the speed of movement is variable true or false
Definition
FALSE it is a static movement
Term
contractility is the ability to contract and develop tensin in the in the same direction as a resistant force when stimulated true or false
Definition
FALSE it is opposite direction
Term
ACTION refers to a specific movement of a joint as a result from concentric muscle contraction tru or false
Definition
true
Term
the term extensibility refers to ability to return to original length after stretching... true false
Definition
false that is elasticity
Term
all contraction are either isotonic or isometric true false
Definition
true
Term
isotonic contraction are concentric or eccentric based on whether shortening or lengthening true false
Definition
true
Term
Eccentric contractions are referred to as muscle action instead of contraction since the muscle is shortening as opposed to lenthening true false
Definition
FALSE Eccentric training is defined as active contraction of a muscle occurring simultaneously with lengthening of the mu
Term
antagonist muscles are know as primary prime movers true false
Definition
FALSE a prime mover is the agonist
Term
isokinetic is a type of dynamic exercise using concentric and or eccentric muscle contracions
Definition
TRUE
Term
ISOKINETIC IS A TYPE OF DYNAMIC EXERCISE that uses concentric and eccentric muscle contractions
Definition
TRUE
Term
When antagonist muscles contract concentrically they perform the opposite joint motion of agonist
Definition
TRUE
Term
usually as a muscle gets longer its ability to exert force is increased
Definition
TRUE
Term
conscience awareness of position and movement in space is kinesthesis
Definition
TRUE
Term
What is affected by the shape and size of muscles?
Definition
the ability to produce FORCE....
not the rate of contractions
not bone structure not location of nerve.
Term
muscles are named for
Definition
shape size function
NOT nerves
Term
Isometric exercise tools perform exercises or strength test using ____contraction of a muscle without any visible movement in the angle of the jo
Definition
static is isometric..
NOT dynamic dynamic is isotonic
Term
In an isotonic contraction,
Definition
tension remains unchanged and the muscle's length changes...dynamic
Term
what is not true regarding isometric muscle contraction?
Definition
not true that is is a dynamic contraction... it IS static
static is isometric
Term
what is true about isometric
Definition
tension .. but joint angle remain constant
Term
what is not true regarding concentric muscle contractions
Definition
described as being a negative type of contractions NO it is positive
Term
true about concentric muscle contractions
Definition
cause movement against gravity r resistance
Term
not true about eccentric muscle action
Definition
typically called positive type of muscle contraction..
eccentric lengthen under tensioon slowly lessons gtnesion to control
Term
true of eccentric
Definition
The force developed by juscle is less than that of the resistance.
Term
true of
