STUDY OF MONKEY, APE, AND HUMAN MORPHOLOGY AND PHYSIOLOGY RELATING TO STRENGTH AND ENDURANCE. PHASE 8. FACTORS IN THE SUPERIORITY OF CHIMPANZEE OVER HUMAN STRENGTH

Abstract

Detailed consideration and testing of hypotheses against available data indicate that the marked two-to-one superiority of chimpanzee over human upper extremity strength per unit of body-weight is apparently due to a combination in the chimpanzee of relatively larger upper extremities, higher proportions of contractile material, smaller average body-size, muscle origins and insertions farther from joints, obliquity of muscle fibers, greater capillary density and glycogen storage in muscles, and greater frequency and ease of innervating a higher percentage of motor endplates, but not so different physico-chemical processes of muscular contraction and not, among the subjects tested, significantly to difference in exercise, although somewhat differential response to equivalent exercise is likely.
