Question 1

length-tension

Answer 1

-muscle produces max force at the optimum resting length
-overactive or underactive, force prod decrreases
(protracted shoulder girdle)
-active tension (actin myosin)
passive tension (PEC)

Question 2

force-velocity

Answer 2

-no time for actin-myosin cross bridges to form at high speed in concentric contraction
—low velocity=high force
-series elastic component allows higher force production at high speed eccentric contraction
—generate more force eccentrically at a higher velocity than conentrically

Question 3

force-velocity-power

Answer 3

-peak power occurs at 30% max velocity and 30% max concentric force
-power affected by muscle strength and speed
-best power training=loads of 30% 1RM
