A chimp on four legs can easily outrun a world-class human sprinter. But it sounds extreme to suggest that humans are only an eighth as strong as chimpanzees. Consider that a large human can bench-press 250 pounds. If the "five to eight times" figure were true, that would make a large chimpanzee capable of bench-pressing 1 ton. It's just the sort of factoid the zoo staff might tell you to keep you from knocking on the glass.
