The force of fetus kicks in the womb measured for the first time

It is a well know fact that a fetus moves and kicks inside the womb of the mother. Until now the mechanical forces and biomechanics of these fetal movements have never been measured. Using modeling of cine-magnetic resonance images scientists managed to quantify the fetal kick and muscle forces during the second half of gestation. Amazingly the force of a fetus kick was around 4 kilograms (8.8 lbs) of force, quite impressive for a developing human being. The stronger kicks occurred between weeks 20 and 30 of gestation. These movements are benefic for the babies because they promote development of muscles and bones.

See below an example of one of the movies used to measure the kicks:
