Explain Why is muscle that has sustained significant damage unable to produce the same amount of power as it could before being damaged?
Slow twitch muscle fibers are
characterized by all of the following
EXCEPT:
O a) used in endurance type of
activities
O b) contract rapidly and forcefully
Oc) resistant to fatigue
O d) have a direct relationship to the
oxidative energy system
Why will an increase in the strength of a stimulus cause an increase in the force of contraction in a whole muscle but not in a single muscle fiber?
