Who is
running the most efficient?
redaction
They are the women in the interior of Africa, who must lift heavy loads on their heads. Expenses that make them modify gait up - in a way - to become more energy efficient, less tense muscles and allow carry heavier loads with longer.
Confidential runs the women lies in the way the body of transferring energy between a half-step and half step the first part of the second part.
Do you know ?
Most people walk inefficient, only utilizing 65 percent of the energy is taken. As many as 35 percent of the energy is lost to move muscles unnecessary.
1. The first part of the half-step
Center body weight ... up slightly in a half-step, forward movement slowed; kinetic energy down.
When the pace slows down motion, kinetic energy is transformed into potential energy, which is increasing concurrently decreasing kinetic energy.
2. Half the step part two
The potential energy turns back into kinetic energy, along with the movement of the center of gravity of the body down.
The key is a load on top of the head
Expenses in the head unwittingly increase the transfer of energy by 80 percent or more, freeing the muscles to lift weights.
Without the weight in the head, the efficiency was not achieved due to the reduced amount of potential energy in the second half-step section is not proportional to the increase in kinetic energy, which occurs because the body does not immediately come forward, causing loss of some energy.
