Humans can run Leopard?

Humboldt in Beijing for the Olympic Games hit 100 m world record 9.69 seconds, a United States professor said that, if he is not looking after 70 meters, enough to generate amazing results 9.55 seconds. However, the field battle because of absence of TysonGay left a suspense. At the end of the last performances of an anniversary, Humboldt and in Berlin to record shortens 0.11 seconds — — very close to the professor's expectations.

Bystanders are tempted to ask: who can run faster? most big prediction is 100 meters 6 seconds.

Once a reporter asked biodynamics home PeterWeyand: one in 6 seconds ran 100 m? experts answer: "Leopard anyway you can. "" That you said? "and" this ... Our people and Leopard have similar muscle ... "said:" mankind is hundred-meter limit results in 6 seconds, so I feel quite safe to predict. ”

Boldt, since you have Leopard-like muscles, why just ran out of someone half level? 10 years ago, scientists on Leopard's leg muscles were demolished and analysis.

They found that, although in a very good case, human rapid contraction of the muscle cells of the ratio can reach 70%, and the Cheetah is similar, but Leopard of glycogen, but at least is the decomposition rate of 2 times. Other person in charge of energy in the body they use enzymes, but also humanity far behind.

Take a look at the physical principle.

Speed is affected by body weight and body fat on the ground of dual limit. Although bolt can be from 1/10 of seconds to four or five times the weight force blow, but man is but a Cheetah Sprint 40 kg, and it a bit, Humboldt is a big fat! mention Leopard can also exerting force four foot?

Mathematicians are adopted a "fixed as mountain" way of working, they are not of human body structure, nor of physiological knowledge, but sitt

ing in front of the computer, the record of the history of mankind to synthesis segment speed record of logarithmic curves. The trend of this curve that proclaimed the "limit" of the data, if new data have emerged, they only need to be joined, recalculation, then you have to be amended, the new curve and limit data.

Many biologists to scoff: a lifeless curve, neither consider the development of science and technology, nor does it consider nutrition and training methods, how to be precise with our sophisticated analysis in the same breath? but mathematicians also has its own rebuttal: the curve has actually happened in the history of changes in logging in, for example, athlete training from week 2 to 3 times, in addition to 5 times, the world record is again rising; another example "drugs," the birth of this concept to the world record of a certain limit ...

All these factors make the shape of the curve. In turn, these worthy of consideration factors too many biologists also impossible projection process all catered for. In fact, mathematicians have long wait methods project won a people's convincing.

People in interpreting the curves have a heart, after all, the famous "nature" magazine is published in 3 years ago about a paper, depending on the fit curve prediction: because of advances in women's 100 m record, so the trend is too significant woman will run across the man, this thesis natural in athletes territories became a joke ...

Said here, people cannot help but think of the word: "Weyand solely from the definition of the ' limit ', the speed limit is not known.

" Make is not good for many years, players have learned four foot Pao Lu, biologist can put humanity with Leopard on the same starting point for comparison of science; perhaps the next match will be clearly specified:" athletes only feet touching the ground ".
