Measured fetal pedal force in the womb

According to the research results published in the Journal of the Royal Society Interface, around the 18th week of pregnancy, pregnant women begin to feel the movements of their babies in the abdomen.

To study, British doctors modeled on computers based on magnetic resonance imaging data - (Photo: Science magazine).

At first, these movements are not strong, but gradually increasing strength can help mothers feel quite clearly the movements of the hands and feet. A group of doctors in London, England, identified the approximate force of those movements.

To do this, computer models are set up by them based on the database. The data was collected through the scan taken from the week of pregnancy 20 to 35. Scientists have discovered that the fetus is able to exercise at maximum strength from 20 to 30 weeks , and then the force decreases, because The fetus is quite large and has no free space to move strongly. Maximum, fetal pedal force can reach 45 Newton (abbreviated as N), equivalent to a body weight of over 4kg.

The authors of the study point out that fetal movement is essential for the precise formation of joints as well as for the development of muscles and bones of children.
