Abstract: | When the functional differentiation of 83 kinds of limb and trunk muscles ofMacaca fuscata was investigated on the basis of the activities of two glycolytic enzymes lactate dehydrogenase (LDH) and aldolase] and
one oxidative enzyme succinate dehydrogenase (SDH)], the forelimb rather than the hindlimb muscles proved have higher oxidative
activities. These results indicated that, inMacaca fuscata, the forelimb muscles have a higher resistance to fatigue, and that the hindlimb muscles have a higher tetanic tension on
the basis of the relationships between enzymatic activities and functional properties of the muscle fiber types. These findings
were interpreted in relation to the fact thatMacaca fuscata is a quadrupedal primate with arboreal habits, as compared with nonprimate terrestrial quadrupeds. The two-joint muscles
and the superficial muscles contract more rapidly than do the other muscles in the hindlimb, thereby suggesting that both
types of muscles readily adapt to quick movement. |
