Bear and bigcats anatomy

[Polar]

@parvez,

I still doubt your assessment. Even in big cat videos (after a quick one minute fighting bout), the fighting participants tire out very easily. Both bears and big cats are capable of power that almost no other group of mammal possess, so it makes quite sense that they should tire out more easily (assuming they aren't at a constant pace.)

Even so, bears hold the record for being able to run much farther than a feline at the same speed, even beating the wolf's endurance within this aspect. They are better grapplers due to increased limb flexibility and robusticity, and thus are able to do this for prolonged periods of time.

Not to mention the muscles of a bear are greater suited for endurance and brute force, than those of a canid or felid, which are more for sprints and explosive power. However, bears can still produce the same power as the other two carnivoran groups, even with less fast-twitch fibers. The reason to this is still being looked into by the informative Ursus Arctos from Carnivora. Reply
