Slow-twitch can work for longer periods without tiring, and are the endurance champions of your muscle fibres. Fast-twitch, on the other hand, are the sprinters, tiring fast but putting in a strong effort quickly.
The researchers found chimpanzee muscle fibres were longer than those of humans and were present in different ratios. However, we also found that chimps have about twice as many fast-twitch fibres as humans," says Umberger. Plugging the data into a computer simulation suggested such differences could result in muscles that were 1. Putting this into an evolutionary context, it would make sense that human muscles sacrificed a small amount of brute strength for more slow-twitch fibres.
The researchers' computer simulations revealed that these differences in muscle characteristics increase the maximum dynamic force and power-producing capacity of chimpanzees by a factor of 1.
The price of that power, though, is that chimps and other apes tire more easily and cannot walk great distances to find food — or, for that matter, to find new lands and make new discoveries. The finding is independent of body size and instead concerns the physical property of individual muscle fibers, O'Neill said. Both humans and chimps can gain strength through exercise and the creation of more muscle fibers. Rather, pound for pound, chimps have the advantage in a fight.
