Chimpanzee ‘super strength’ and what it might mean in human muscle evolution

(University of Massachusetts at Amherst) For years, anecdotes and some studies have suggested that chimpanzees are 'super strong' compared to humans, implying that their muscle fibers are superior to humans'. Now a research team including a UMass Amherst kinesiologist reports that contrary to this belief, chimp muscles' maximum dynamic force and power output is just about 1.35 times higher than human muscle of similar size, a difference they call 'modest' compared with historical, popular accounts of chimp 'super strength,' being many times stronger than humans.
