How many people do people have?
Through computer simulations recently, there are three types of movements for people that are most effective: walking, running, and a third type that some people do not use.
Walking and running is a common type of movement for human walking because it has the least energy consumption.
Engineers at Cornell University compared the mechanical properties of walking and running with many different and unused ways. They use a computer program to simulate physical measurements, such as leg length, thrust, speed of body, path, initial speed and muscle movement. ' We hope to find out how people move from one place to another with the least muscle movement ,' they write.
The answer from the computer is that the third form - half goes half way - is optimal with average speed, neither too fast nor too slow. Even so, people still do not exploit the benefits of this third type of travel.
