If the muscle fiber is stretched to 150% of muscle length and thentechnically stimulated, what would be the total force measured?
What are the variables of the PCSA and what are the tradeoffs of these parameters to muscle function?
b. What are the muscle fiber orientations and why would the body choose one orientation over another?
Hill's equation gives a relation between muscle contraction rates νν and muscle tension TT
(T+α)(ν+β)=(T0+α)β(T+α)(ν+β)=(T0+α)β
for positive parameters αα and ββ and resting tension T0T0. Rewrite the equation so that the contraction rate is a function of tension.
