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 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.
