The Bear Almanac by Gary Brown. STRENGTH - Bears possess enormous strength, regardless of species or size. The strength of a bear is difficult to measure, but observations alone ( bears moving rocks, carrying animal carcasses, removing large logs from the side of a cabin, and digging cavernous holes ) are indicative of incredible power. A study team at Montana State University in Bozeman, Montana, found that a grizzly bear could treat a 700-pound garbage dumpster like a beach ball, while it took a minimum of two persons just to tip the dumpster. The team concluded the strength of a "calm" grizzly is two-and-a-half to five times that of a human.
No animal of equal size is as powerful. A bear may kill a moose, an elk, or a deer by a single blow to the neck with a powerful foreleg, then lift the carcass in its mouth and carry it for great distances. "The strength... is in keeping with his size," describes Ben East in 'Bears'. "He is very powerfully built, a heavy skeleton overlaid with thick layers of muscle as strong as rawhide rope. He can hook his long, grizzly-like front claws under a slab of rock that three grown men could not lift, and flip it over almost effortlessly... a brown bear took a thousand-pound steer a half mile up an almost vertical mountain, much of the way through alder tangles with trunks three or four inches thick." Strength and power are not only attributes of large bears but also of the young. The author observed a yearling American black bear searching for insects turn over a flat-shaped rock that was between 310 and 325 pounds "backhanded" with a single foreleg. The bear was captured the following day in a management action and was found to weigh only 120 pounds.

The Grizzly Book by Jack Samson -
The Trouble with Grizzlies by Thomas Hardin.
With the hide off, the carcass of a grizzly looked like the naked body of a grotesque and tremendously powerful man. The great ropes of muscle show where the bears get their strength. They can crush the head of a moose or a buffalo with one blow, literally powder the backbone of the largest steer. I once saw a rather small female grizzly uproot the stump of a dead timberline tree with one smooth, effortless pull. apparently she did it as easily as a tractor would have done.
Grizzlies have been known to carry away the entire carcass of a bull elk that would weigh from 700 to 800 pounds, and to drag that of a bull moose for a mile - and a big bull will weigh 1,200 or 1,300. When a grizzly puts his mind to it, he can break open the door of a trapper's cabin as if he were an animated battering ram. For his size, he is one of the most powerful beasts that walks the earth.

Guys, this is not even a debate, the grizzly would leave both cats on the dust. All the upper body advantages go to the grizzly, even jaw power at higher weights.

Posted elsewhere by our friend, BoldChamp: I knew what he meant, but bending the spine still reduces leverage. A straight spine is a stronger one. *I view this as comparing a steel chain to a steal beam. The steal chain is strong, but the solid steal beam is stronger. There are no doubts as to which animal is stronger. However, there are other factors involved. 1- Using the technique provided by the usage of the flexible spine, can the big cat pull as heavy of a load as the grizzly with his straight sturdy spine? 2- Will the stronger jaw strength of the big cat make a difference in this tug-o-war?

The crazy thing about bears is that they possess BOTH power and strength Strength is endurance - lifting something or engaging in activity over extended periods of time = endurance Power is lifting or engaging in activity at max levels, but for a short time - NOT endurance Cats tend to be powerful for bursts , they donāt maintain it long Bears are CRAZY powerful AND strong at the same time - that makes for a really SCARY individual! š»

shaggygod.proboards.com/thread/188/general-discussion If you want to see evidence of a grizzly bear or brown bear's pulling capacity one suggestion would be to find literature or video references of them pulling a bison or moose carcass for example ones that did not survive the winter (the ones that have not decomposed) or better yet relating carrion extraction from a river or in other cases where the bear will pull the victim to hide and bury/cache it. The polar bear have be known to pull out of water onto the ice a Beluga whale which may weigh five times as much as the Polar Bear (Freeman 1973). FWIW, I think a lot of these online 'bio-mechanical' arguments have reached dimensions of the absurd.

FWIW, I think a lot of these online 'bio-mechanical' arguments have reached dimensions of the absurd. What comes to "bio-mechanical" arguments, I agree 100%. People in different forums argue with things, which they have 0 competence to explain. Like, cats arenĀ“t strong because they are "made for speed" and thatĀ“s why they arenĀ“t strong. Same time there is footage showing that yes, cats are strong. Only cheetah is a cat which has evolved mainly to speed. When looking at tigers, lions, leopards and jaguars itĀ“s easy to see that they are both, relatively fast but same time very strong too. And there is a lot of footage backing it up. No need for any amateur, should I say, "wannabe biologist" to try to explain something what he canĀ“t. I have read so many postings in which people quote some studies in superficial way, while they have really no idea what they are talking about, when trying so hard to prove something. Bears of course are obviously very strong, while in some books descriptions are giving some pretty... well, interesting descriptions, real clips from different places show more down to earth performances. But itĀ“s obvious that bears are strongest carnivores, they have robust body structure and size. And some performances caught on tape are something what IĀ“ve never seen from biggest cats. ItĀ“s no contest what comes to absolute strength alone.
