The largest captured male (784) was 13 years and the largest captured female (825) was 15 years old. Differences in their respective sizes were as follows: weight, 390-275 kg; height at shoulder, 152-130 cm; total length, 264-228 cm; hind-foot length, 44-38 cm; neck circumference, 90-80 cm; chest girth, 159-157 cm; body length, 140-127 cm; skull length, 473-403 mm; and zygomatic width, 311-251 mm. When all measurements were combined, mean total body size of 5 males over 9 years of age was 19 percent larger and their mean body weight was 88 percent heavier than the sizes and weights of 25 females of comparable age. 390 kilograms is equal to 859.80 pounds (avoirdupois)

Shadow: What comes to bear strength and tests, those tell maybe something. But I find it odd, that we know next to nothing even about documented tests like the one in start of this thread. No photos showing test wall and conditions, not even some drawing to demonstrate what it was all about. Not too much details so, that someone could for instance repeat same test in same conditions and compare. It is actually quite difficult to make too much conclusions about tests, which are not known too good. Maybe there is somewhere more information about that test. I admit, that I looked at it only breafly, but some "wall" was dragged and in some way pulled upwards I think. No comparison with some strong man for instance doing exactly same things. Odd.
But here is a video, which demonstrates quite good, that bear is pretty strong and capable. "Action" starts to heat up in about 1:35. I would say, that quite impressive wrestling there.
Ps. I checked again that power test. That lifting a barbel with 387 kg weight was truly impressive from that bear. That is a weight, which most men couldn´t even hope to lift at all, I mean not lift even half an inch from ground, only get back hurt badly if trying too hard. That lift is maybe most impressive show of strength I can remember from any mammal compared to size of that bear. Dragging and pulling heavy objects is much easier than many realize, but actually lifting like in that test. That is undeniable strength. When reading that text, it gives strong indication, that bear wasn´t even close to maximum with that weight.
When comparing that to Eddie Hall, who deadlifted 500 kg practically fainting after that lift and suffered afterwards about multiple symptoms caused by extreme effort. And which is most ever lifted by a man and at the time Hall was himself about 180 kg or so. Here we have a bear 83,7 kg, who lifted with ease 387 kg and might lift even double or triple that weight if really trying hard (if we believe what those scientists said). That is quite something.

Brobear: I have watched that video numerous times. It shows the strength and wrestling ability of the grizzly she-bear as well as her courage and determination to feed her cubs and herself. Also, those caribou antlers are sharp. I could almost hear "the gears grinding" in the bear's head - bears are thinkers. Great video Shadow.

Shadow: Adult predators show quite good their experience and it was obvious, that this bear understood danger with antlers. Anyway here we could see a predator making an attack without surprise element and practically "wrestling" opponent to fall down. Not an easy task to do when prey is bigger than predator. And before someone rush to say "that it bite also that caribou", I would add, that I know it and I saw it, but this was still impressive.
Still when I read that research from Russia, it is maybe even more surprising. I mean many times people talk about gorilla making comparison how many times stronger it is than a human (never it is quite clear if comparison is to average man or someone really strong and we never have anything where to compare actually). Then here we have a test showing, that bear lifts 4,6 times it´s weight and wasn´t even close to maximum. There we have one very comparable result from a bear now. Anyone can go to gym and test.
But I think, that this is quite unknown test though. I find it surprising when knowing how interested so many are about animal strength. And there we have a 83,7 kg bear showing to be most probably stronger, than strongest man ever. And I don´t mean now about that pound for pound alone, but I mean, that how much it can lift actually compared to a man, who lifts more weight from ground than anyone else. Those scientists seemed to think, that it could have lifted anything between 770-1100 kg. Even if they would be wrong, we have a fact, that this bear lifted about 400 kg just like that, effortlessly. I think, that it is quite safe to assume, that at least anything between 500-600 kg would be possible and that alone is quite something. I think, that most untrained men weighing 84 kg would have hard time to lift even 100-120 kg. Someone trained would lift maybe 140-160 kg. Trained powerlifters (with steroids... oh, sorry, of course they are all "clean" ;Wink then more, but still nowhere close to what this bear did there.
1 pound is 0,454 kg, so 400 kg is about 881 lbs.

I believe a strength test has never been done on a 1500 lb brown bear, so just imagine.

wildfact.com/forum/topic-bear-strength Shadow ( post #131 )... It is. What comes to this test and which is, as I have said, interesting, that here we have a very unambiguous test, where bear lifted impressive weight with ease. So even without giving all, it made it crystal clear, that it is way stronger than human, no matter if that human is average man or strongest there is. And this test is so simple as it can be, no guessing about surface where something was pulled or was there wheels and if not, what material was pulled item and what kind of friction.... I demonstrate what I mean by documentation. This video leaves nothing unclear. This is also a test, which anyone can repeat anytime and be sure, that results are comparable. Of course it is a competition, but I am amazed how little we have footage or even photos of some tests. With footage like this there would be a lot less "what if" and "but". Btw. I think, that bear wouldn´t do that same what those horses do.

Grizzly compared with strongest man in the world... Bear can lift more - pull more - push more ( and do so easily ). No big cat can compare.

shaggygod.proboards.com/ BIG BOY ON THE MOVE In that time, Big Boy moved out of the park towards the female, then spent four days with her before heading off toward the smaller male. Presumably he mated with the female. Whether there was an encounter with the smaller male is unclear, but the tracking map clearly shows the smaller animal making a bee line out of the area once Big Boy arrived. In the short time he has been collared, Big Boy has already made a reputation for himself. The next time the research team saw the big 300 kg bear, he was 3,000 metres high climbing the side of a snow covered mountain. "It was weird," says Stenhouse. "We saw these tracks in the snow way up high and decided to see which bear it might have been. It must have taken the helicopter 10 minutes to get up high enough to see it was Big Boy. He could have easily crossed to the other side by going over the pass lower down. But for some reason, he just went up and over the peak." The scientists also observed things that made them think twice about the relationship between grizzlies and people in the back country. In one case, biologist Robin Munro and Bell saw hikers walking along a trail. Above them no more than 100 metres away was a grizzly, evidently aware of the people below. "The bear just waited until the hikers passed, then it crossed right behind them," recalls Munro. "The hikers were oblivious to the bear’s presence." On another occasion, the scientists saw a grizzly running down the side of a mountain with a bighorn sheep in its mouth. "That sheep weighed maybe 300 pounds," says Stenhouse. "Yet, the bear was moving so fast the legs of the sheep were flapping behind it like a man’s tie blowing in the wind. It turned out to be Big Boy. The power of these animals is just awesome." Some scientists believe that in order for a species like the grizzly to survive, there must be enough animals present to avoid inbreeding and to be able to recover from food shortages, disease and forest fires. Grizzly bear populations on provincial lands in Alberta have increased from an estimated 550 in 1987 to more than 800 in 1999, not including the 100 animals thought to reside in Jasper. But there is considerable debate about the current status of the species and its future given the increasing fragmentation of habitat. That’s why Strobeck and Wasser were brought in to do DNA profiles of the bears. The genetic profiles they put together will help scientists keep track of the animals during and after the five year project and validate the way scientists currently monitor grizzly populations over the long term. Strobeck is using the more traditional method of extracting the DNA from the hair of the animals. He did that by setting up scented barbed wire structures throughout the study area. When the bears comes in to check it out, it invariably leaves a few clumps of hair on the wire.

shaggygod.proboards.com/ Gravity-Defying Grizzlies March 19, 2015 And, indeed, that proved true in testing. First of all, Big Boy turned out to have the highest level of testosterone of any bear whose blood they had analyzed, but also, Stenhouse points out, Big Boy “produced a lot of cubs with females inside [Jasper] National Park as well as outside.” Grizzlies have a well-deserved reputation for toughness. They are formidable predators who can weigh more than a thousand pounds (though more typically under 800 pounds), knock down a moose with a paw swipe, toss rivals through the air, and run nearly as fast as a horse. They can stand seven feet tall on their hind legs.

www.allgrizzly.org/front-limbs Front limbs Of all the morphologic features that typify bears, the front limbs and associated skeletal infrastructure are the most distinctive. They are also diagnostic of the bear life strategy (see Life strategy). No other terrestrial vertebrate of its size--certainly no other large carnivore--has front limbs that are as flexible, powerfully built, and mounted with such dexterous paws. Nor do any comparable-sized carnivores have such out-sized claws...claws which are clearly "designed" to be powered by the muscular arms and shoulders to either climb trees, extract food from a durable matrix (i.e., dig), or grapple with and subdue large prey such as seals, moose, and elk. What follows is a summary of the evidence produced over the years elaborating on and substantiating the preceding thumbnail sketch. You will have to forgive me for the abundance that follows, but it is reflective of the extent to which I see this aspect of bear morphology as key to understanding the overall bear life strategy--as well as niche.

I definitely agree that bears arms are super strong. A bear can move ad dumpster around like a beachball. That's what I remember reading from a source. I even seen videos of bears moving dumpsters effortlessly. The power of ursids are amazing.

I got this from Kodiak at Wildanimalwarfare so all credit goes to him. Here is an expert stating that bears have more strength than big cats. The limbs and in general. Blaire Van Valkenburgh Professor of Ecology and Evolutionary Biology at UCLA, she is also President of the Society of Vertebrate Paleontology trowelblazers.com/blaire-van-valkenburgh/“If bears are not built for speed, then what does the combination of massive limbs, plantigrade hindfeet, cumbersome paws, and a short back provide? Strength and mobility of limb movement are the answers. The stout limbs of bears are capable of producing large forces over a much greater range of motion than those of dogs or even cats” “Cats are more like bears in their range of possible movements, but lack strength” SPEED AND STRENGTH All bears have a large head with small ears followed by massive shoulders and a short back and | tail, all of which are supported on thick limbs and broad paws. Compared with big cats, bears have longer snouts and shorter, stiffer backs. Relative to large dogs, bears have bulky legs and much more spreading feet. Unlike these other carnivores, and more like humans, bears walk on the soles of their hindfeet, with their ankle joint positioned just above the ground. This condition is called plantigrade, and differs from the digitigrade posture of cats and dogs, in which the “soles” of the feet are elevated, along with the ankle, and only the toes touch the ground. To understand why bears are built so differendy from cats and dogs, it is essential to explain the benefits of digitigrade feet. Running around on your toes in a digitigrade posture is advantageous if speed is important. Speed is the product of stride length and stride frequency. Raising the ankle adds length to the part of the limb that determines stride length, that is from the shoulder or hip to the point of contact with the ground. Longer limbs take bigger strides, and digitigrade posture is therefore typical of mammals designed to run. Digitigrade animals also tend to have relatively long bones, or metapodials, making up the sole of the foot, adding further to total limb length. In addition, their limb muscles are much thicker close to the hip or shoulder joint, and taper towards the toes as long, elastic tendons. This construction reduces muscle mass near the ankles and feet, where the limb travels farthest during locomotion, and thus reduces inertial effects. A The skeletons of a bear and a domestic dog illustrate the difference between plantigrade and digitigrade postures. The dog is digitigrade, standing on its toes with the soles of its feet (metapodials) off the ground. By contrast, the soles of the bear's hindfeet are flat to the ground, as in humans, giving it a plantigrade posture. If one imagines the additional energy required to walk or run with ankle weights or heavy shoes, then the drawbacks of heavy feet become clear. There are yet further benefits to runners in having long tendinous muscle attachments. Tendons are elastic and act as energy-saving springs when running. They are stretched as the limb is flexed under the weight of the animal and then rebound, propelling the body forward and upward. So, digitigrade posture, long metapodials, and compact muscles with stretchy tendons are typical of carnivores built for speed. Bears are clearly not built for speed. Although their forefeet are semi-digitigrade, their hind-feet are plantigrade. Moreover, their metapodials are short and their muscles thick throughout the length of the limb. In many ways, bears are built more like badgers than other similar-sized carnivores, such as tigers, and it shows in their speed. The top speed recorded for both black and brown bears is 50 kilometers (30 miles) per hour, whereas the range for the fully digitigrade lion and wolf is 55 to 65 kilometers (35 to 40 miles) per hour. If bears are not built for speed, then what does the combination of massive limbs, plantigrade hindfeet, cumbersome paws, and a short back provide? Strength and mobility of limb movement are the answers. The stout limbs of bears are capable of producing large forces over a much greater range of motion than those of dogs or even cats. Bears use these capabilities when digging for food or shelter, fishing for salmon, climbing to escape danger, and battling with members of their own species as well as other predators. Imagine a wolf trying to perform a bear hug or climb a tree. Dogs have forfeited these abilities in favor of speed. Cats are more like bears in their range of possible movements, but lack strength. Bears may not be able to outrun danger, but can successfully defend themselves through brute force.

Thank you very much bro, but i got that from page 2 of this same thread, so the credits really are to Brobear. I just posted that over at Wildanimalwarfare to show some tiger nerds that bears have more strength than cats according to a very good paleontologist and evolotionary biology professor.

mytakeontv.wordpress.com/2009/05...-anderson/ What is something that you learned in spending the year with Grizzlies that has affected your daily life going forward? Insight from Brutus: if it is physically possible, then it is done. If not, it isn’t. After weighing a boulder in at one ton, we used a tractor to lift it to place a piece of salmon under it. Soon after, Brutus caught the scent of the salmon and walked to the boulder. In one swift move, he pushed the boulder to the side and happily devoured the salmon. It dawned on me as I stood next to my friend: he doesn’t worry much; he is not handicapped by his mind. If his body isn’t capable of doing it, then that is his only limitation. He does not sit there and contemplate, or make excuses; he just does all he can. Then goes and takes a nap in the sunshine. How great would it be if we could all live that way?

You guys think a tiger can move a one ton boulder? Please, tigers can only move large weights only using its teeth.
