muscle stuff

Question 1

muscle power

Answer 1

muscle force x contraction velocity

Question 2

most efficient muscle temperature

Answer 2

101.3
-moderately elevated temp increases speed of nerve and muscle function

Question 3

force-time relationship

Question 4

electromechanical delay

Answer 4

time needed to get slack out of tendons
-childrens EMD is much longer
-long delay, high COG, low skills, movement in growth parts

Question 5

Why can’t we measure muscle strength

Answer 5

muscle is connected to the bone and muscle works with other muscles
-measure torque instead

Question 6

muscle strength

Answer 6

tension generating capability of a muscle is related to its cross section area and training state
-90N/cm

Question 7

Rotary component (y)

Answer 7

perpendicular to the bone
-causes motion to occur

Question 8

Stabilizing component (x)

Answer 8

parallel to the bone
brings the two articular surfaces closer together

Question 9

purpose of patella

Answer 9

increase the mechanical advantage of the quadricep muscles by increasing the rotary component
(makes quads more effective at knee extension)
(increases perpendicular comp.)
