|
capacity of a muscle to do work equation? |
muscle performance Work= force x distamce |
|
|
three key elements that are considered part of muscle performance |
endurance, power, strength |
|
|
factors that can impair muscle performance |
injury, disease, immobilization, disuse, inactivity |
|
|
any form of active exercise in which dynamic or static muscle contraction is resisted by an outside force applied manually or mechnically |
resistance exercise |
|
|
what is the muscle length of concentric mvmt
" " of eccentric? |
shortening lengthening |
|
|
for concentric...lifting or lowering phase of the open chain mvt
for eccentric? |
lifting lowering |
|
|
Does concentric cause movemnt or control movement
Does eccectric cause movement or control movement |
cause control |
|
|
isometric ex
examples? |
mm contracts and produces force without change in the length of the muscle and without visible jt motion
quad sets, pushing against a wall |
|
|
isokinetic contraction( Accommodating resistance exercise) |
a form of dynamic exercise in which the velocity of muscle contraction and the limb velovcity is set and held constant by a machine |
|
|
example of "sustaining" tension"
example of "regulating tension" |
holding a book pick of book, set it down, pick up paper (changing gears) |
|
|
what factor do you manipulate for power |
shorten time or increase work |
|
|
responses to exercise( with no delay) |
improve blood flow to mm increased HR increased oxygen increase rate and depth of respiration |
|
|
adaptions to exercise |
muscular hypertrophy of type II fibers increase motor unit revruitment increases tensile streghth increase mitochondrial density and volume |
|
|
what does SAID stand for? mean? |
specific adaptions to imposed demands exercises should mimic functionxxccxxcxc |
