The ultimate test of strength, athletes can lift up to three times their body weight. Weightlifting was part of the first modern Olympic Games in Athens in 1896, with women joining in at Sydney 2000. There are eight men’s and eight women’s events.

Once again, they specifically say vertically aka a deadlift... That is what they compare to human beings, they don't present a number for horizontal pulling weight in human standereds.
Horizontally would be a truck pull or a chain drag.
Also Olympic weightlifting is.... Clean and jerk and overhead snatch, they don't have the deadlift, bench or squat in the olympics, although they should.

And in this test of strength, a weightlifter can pull from 2.5 to 3.5 times his own weight while the sub-adult bear can pull over 20 times his weight.

A Historic Grizzly by Bob Nolin... The power of a grizzly is second to none. To illustrate this, a man, whom I know, was mauled by a grizzly after lifting the gate of a culvert trap as he released the bear. In seconds the bear was out, pulled the trap off the flatbed and caused Louis, who was positioned on top, to slide down the top length of the trap onto the bear! The power, strength and speed to do all this in the short time it took Louis to hustle from the front to the back of the culvert trap is amazing! This occurrence greatly impressed two outdoor writers who were witnessing the release. One said afterwards that he had heard of the great bear's power and strength and its amazing feats, but he could not digest it all. After this episode he said there is no comparison between a black bear and a grizzly, since he was only familiar with black bears. Now he is a believer in Ursus arctos horribilis' power and strength.

A Historic Grizzly... A friend of mine was a guide in the Bob Marshall Wilderness. While packing with horses along a trail that paralleled a clff, one of the pack horses slipped and catapulted several hundred feet to the bottom. Doug climbed down to claim all the gear, and decided that the dead horse would serve as bait for a grizzly. Knowing there were grizzlies in the area, he waited high above the horse through the night with the necessary equipment and gear in anticipation of an opportunity at daylight. As the sun lifted in the eastern sky, Doug carefully studied the landscape below, only to discover the horse was missing! He was totally bewildered as to what happened to the horse! Doug climbed down the cliff and found that the horse was dragged a couple hundred yards to the Middle Fork of the Flathead River by a grizzly! Doug waded the river and continued following the drag marks, which led to a huge bear cache! After carefully surveying the sight he decided against any more grizzly hunting. The one thing that stood out in his mind was the awesome strength of an animal that was able to drag a mountain horse that distance!

A bear cannot VERTICALLY pull 20 times its own weight only horizontally and a human can probably pull pretty close to that as well.
"Conclusion: Bears are noted to be extremely strong by both literature and first-hand accounts, and this approach is also true for very young bears. The ratio of the VERTICAL pulling weight to the young bear's weight approximated at 4.624x, and the ratio of the HORIZONTAL pulling weight to the young bear's weight approximated at 20.550x, slightly more than 20 times his own body weight. Powerlifters and other humans, who lift according to their body's maximum loads, will usually VERTICALLY -pull 2.5 to 3.5 times their body weight. The power of the young bear in this experiment was astonishing, and this finding could provide more light into the muscle function of not only brown bears, but all bear species in general."

A Historic Grizzly... My father-in-law and brother were on a fishing trip to the peninsula of Alaska. One night a grizzly took their fifty-five gallon drum that was sealed with garbage and bent it like a pop can! Immense strength is almost an understatement. They decided that moving on might be their best proposition.

Brotherbear,
That 20x ratio is for HORIZONTAL pulling strength (which makes more sense), not vertical pulling strength.
RE: Bear Strength - brotherbear - 06-01-2016
A Historic Grizzly... Years ago I witnessed a line of men trying to turn a grizzly over on a mat, much like two wrestlers. If they were able to do so, then they would be awarded a monetary prize. The grizzly with the command by the trainer stood on all fours. The person would put his one hand on the bear's front upper leg ( arm ) and his other over the bear's back. Weight was no factor since this bear was hardly any bigger than these two hundred and fifty pound people. On a command from the trainer the scuffle started, and in a matter of seconds the bear was on top of each of the contestants. One guy apparently irritated the bear because the bear flew up and around in one motion and had the guy pinned! It was a blessing the bear was declawed and wore a face muzzle, or this guy would have been in big trouble. I could hardly believe the quickness of that bear!
In Monterrey, Mexico a California grizzly killed an African lion so quickly that the large crowd weatching did not know how it was done! During that same time frame a grizzly killed a bull in a ring in similar fashion.
RE: Bear Strength - Polar - 06-01-2016
And @Pckts,
A very lightweight human powerlifter can only pull 20x his body weight (with arms and without a harness, facing the object) only if the object is with wheels or on a slippery surface.
Note that this wall had no such helpful mechanisms, and the bear had to only use his force.

OK, and what can a man pull ( according to this test ) HORIZONTAL ?
RE: Bear Strength - Pckts - 06-01-2016
@Polar that is also something I'm curious about... What mechanism did they use for the wall? It had to be on something but you're right, pulling a truck or a plane they are on wheels but the person still needs to initiate the movement and that still means they are pulling that weight without momentum to begin with. Using a harness of course, chain drag or prowler drags usually become slightly easier as the momentum gets going.
They only way to actually compare would be to have humans test themselves on the same mechanism which isn't possible obviously.

In the study, the machanism was a pressurized wall made out of carbon-fiber material with two handles, and that the pressure was controlled according to the weight that was entered on a computer. It would be very similar to horizontally pulling/pushing a metal weight without any wheels or slippery surface.
Imagine a six-foot thick barbell on gravel (Idk why that came to my mind.)
