Muscle Performance and Strength - Lecture 3

Question 1

muscle performance

Answer 1

interaction b/w the physiologic, neurologic, psychologic, biomechanical systems

Question 2

dzs to these systems can affect muscle performance

Answer 2

CV

endocrine

integ

MS

NM

pulmonary

Question 3

3 components of muscle performance

Answer 3

strength

power

endurance

Question 4

when do we use therapeutic intervention to improve muscle performance

Answer 4

impairments to power, strength or endurance

Question 5

impairments must be related to –> muscle performance

Answer 5

fxnal limitation or disability

promote health, wellness and fitness

pain with active motion

Question 6

strength

Answer 6

ability of contractile tissue to produce tension

a resultant force based on the demands placed on a single muscle

Question 7

fxnal strength

Answer 7

ability of NM system to produce, reduce, or control forces during fxnal activities

Question 8

fxnal strength is seen as

Answer 8

smooth and coordinated

Question 9

insufficient muscular strength can lead to

Answer 9

major fxnal losses of even the simplest ADLs

Question 10

strength training is a

Answer 10

integral component of rehab and conditioning programs for individuals of all ages

Question 11

strength training definition

Answer 11

systemic procedure of a muscle or muscle group lifting, lowering, or controlling heavy loads (resistance) for a low number of reps in a short period of time

Question 12

strength training results in

Answer 12

neural adaptations

increase in muscle fiber size = increased muscle strength = increase in the maximal force producing capacity of a muscle

Question 13

muscle power

Answer 13

aspect of muscle performance that is related to strength and speed of movement

rate of performing work

Question 14

how can muscle power be expressed

Answer 14

over a brief period of time or repeated bursts over less time

Question 15

why do we do power training

Answer 15

many activities in our lives are composed of movements that are explosive and involve speed and strength

Question 16

what is an important priority in a rehab program

Answer 16

re-establishing muscle power

Question 17

what is some degree of muscle strength necessary for

Answer 17

developing muscle power

muscle strength is a precursor to muscle power

Question 18

how can power be increased

Answer 18

increasing the work of a muscle must perform during a specified period of time

reducing the amount of time required to produce a given force

Question 19

the greater the muscle power…

Answer 19

the greater the intensity of the exercise

shorter the period of time taken to generate the force

Question 20

endurance training

Answer 20

characterized by having the ability to contract and lift of a lighter load for many reps

sustain a muscle contraction for an extended period of time

Question 21

endurance training is…

Answer 21

low intensity muscle contractions

large number of reps

prolonged period of time

Question 22

endurance training can have a more positive impact on

Answer 22

improving fxn

compared to strength training for some pts

Question 23

endurance training minimizes

Answer 23

adverse forces on joints

Question 24

endurance training produces less

Answer 24

irritation to soft tissue

Question 25

endurance training is more comfortable than

Answer 25

heavy resistance exercise

Question 26

3 key principles of resistance training

Answer 26

overload principle

SAID principle

Reversibility principle

Question 27

overload principle is for

Answer 27

improvements to occur in muscle performance

a load that exceeds the current metabolic capacity needs to be applied

Question 28

muscles need to be –> overload principle

Answer 28

challenged to perform at a level greater than that to which is accustomed

Question 29

what happens if demands remain static –> overload principle

Answer 29

muscle performance will only be maintained

Question 30

overload principle –> strength training

Answer 30

incrementally and progressive increases

Question 31

overload principle –> endurance training

Answer 31

time

number of reps

Question 32

safety and precaution –> overload principle

Answer 32

underlying pathology

age of the pt

stage of tissue healing

fatigue

overall abilities and goals of the pt

Question 33

SAID principle

Answer 33

specific

adaptation

imposed

demands

Question 34

framework for specificity

Answer 34

must be built

Question 35

specificity of training

Answer 35

adaptive effects of training are highly specific to the training methods placed on them

Question 36

exercises should be… –> specificity of training

Answer 36

as similar to (mimic) the anticipated fxn

Question 37

transfer of training

Answer 37

carryover of training effects from one variation to another

Question 38

transfer of training is often referred to as

Answer 38

transfer training

overflow

cross-training

Question 39

reversibility principle

Answer 39

adaptive changes tot he body’s system are transient unless training continues or are incorporated regularly into daily activities
