Can you escape the sloth? Probably. Can you overtake the cheetah? Probably no. Can you run away from the bear? This question is a little more difficult to answer. Most bear species are quite heavy, which can slow them down, however some species are known to be successful predators, which may indicate that they are hunting at high speeds. There are many different approaches to avoiding a bear attack when you come face to face with one in the wild. Should trying to escape be one of them? Here we will consider all possible options for winning the race with a bear and determine whether a person can run away from a bear.
How bears move: biomechanics of a four-legged man
Bears move on four-legged, that is, on four legs. Biomechanics is the study of structure, function and movement in the mechanical aspects of biological systems (cells, organs, whole organisms, etc.). By studying the biomechanics of how bears run, we can understand how effective this movement is, how limited it is, and ultimately how it compares to running on two legs like humans.
Bears have important physiological adaptations that enable them to effectively cope with the physical exertion while running. A 2017 study published in the Journal of Experimental Biology found that in bears, the shoulder-blade joint, where the shoulder bone meets the shoulder, increases energy absorption as speed increases, regardless of gait. This means that as bears transition from walking to running, their shoulder joint is able to efficiently absorb energy.
Larger tetrapods are also generally more efficient runners than smaller quadrupeds. Despite their greater weight, larger four-legged runners can move faster than smaller species. This is because in order to cover the same distance, the shorter limbs must have a higher stride frequency and therefore consume more energy. This allows larger animals to run faster and further. This works in favor of the bear because of its size. Scientists have studied the movement of bears in controlled conditions using a treadmill and found that this assumption of large four-legged animals holds true for bears in terms of faster speed.
However, the bears could not maintain such a high speed over long distances.
How did running evolve in humans?
The human body has evolved to allow more efficient long-distance running than sprinting. The modern theory of evolutionary anthropologists is that the ability to run long distances evolved for hunting purposes. It is believed that when the ancestors of humans began hunting, a strategy called “persistent hunting” was employed. Tenacity hunting is when the hunter tries to run away from prey at a great distance so that he can easily kill when he has exhausted the target animal. It was not easy for humans to chase and hunt animals on the sprint, but they could wear them out.
Other ways humans have evolved to support long-distance running include an efficient cooling system and other anatomical adaptations. People have many sweat glands and minimal body hair. Moisture on human skin from perspiration allows evaporation to cool. It is very effective for people due to the lack of fur or a lot of body hair. Many other mammals cannot handle long-distance running because they can overheat. Humans also have shorter pedaling phalanges (toes) than many other animals, including other monkeys that support long-distance running.
How fast can a person run?
The average sprint speed for an adult is 15 miles per hour. Florence Griffith-Joyner, world record holder in the 100 meter race, ran 21.3 mph in her all-time record. Usain Bolt, the fastest man on earth, has a maximum recorded speed of 27.44 mph.
What are the fastest bear species?
The fastest bear species is the American black bear. The American black bear can easily run at over 35 miles per hour. However, this speed cannot be maintained over long distances. Depending on the season, if the bear has a winter coat and extra weight to prepare for hibernation, the bear will quickly tire and overheat. Typically, black bears travel throughout the home at less than 4 miles per hour.
The second fastest species of bears is the grizzly. The maximum recorded speed of a grizzly bear is 30 miles per hour. The slowest bear species is the polar bear. Polar bears have uniquely large paws that allow them to distribute their weight over a larger area. This is useful when walking on snow and ice, like wearing snowshoes. These large paws also increase the polar bear’s swimming efficiency. However, they prevent them from running on land. A polar bear can reach a top speed of 25 miles per hour on land.
Can a man overtake a bear?
A man cannot run away from a bear if he is being chased. All kinds of bears could easily pursue an ordinary person. The only scenario in which a person can overtake a bear is if a polar bear is chasing Usain Bolt. However, a person can overtake a bear in distance. If a person was hunting or chasing a bear, they could overtake the bear to exhaustion and catch it. However, if the bear was chasing a man, the man would have little chance. Bears win at short distances, and humans win at distance.
What if you meet a wild bear?
Instead of trying to run away from the bear, you can take other steps to avoid being attacked. First of all, before going on a hike or hike, explore areas where bears may be, depending on the season. Knowing where certain bears usually roam can allow you to avoid meeting altogether.
If you come across a bear in the wild, stay calm. Do not try to attack or attack the bear in any way. If you are with small children, pick them up immediately. Speak calmly with the bear in a low tone so that he understands that you are a person, not a prey. Do not shout, mimic the sounds or growl of a bear, or make sudden movements that could scare the bear. If they stand on their hind legs, most likely out of curiosity to see you better, and not because of an aggressive posture.
In the rare event of an attack, there are two ways to respond, depending on the type of bear. If it’s a brown or grizzly bear, lie on your stomach and pretend to be dead. Do not remove your backpack so that it can protect your torso and fold your arms at the back of your head. Spread your legs out to the sides to make it harder for the bear to turn you over. Stay where you are and the bear will likely lose interest. Retaliating against the brown bear will only increase the intensity of the attack. If the attack continues, try to punch the bear in the face with any available object. If you are attacked by a black bear, do not pretend to be dead. Try to escape to a safe place, such as a car. If you can’t escape, hit the bear in the face.
