Yessoufou L, Lawani MM and Dumas G

The present study implements the use of the method of Jensen to analyze the inertial parameters segments (masses and center of mass) among 30 women including 20 in a state of pregnancy. Recruited as of the 1st trimester of pregnancy, these last voluntarily took share with the experimentation. These women all are healthy, and have no apparent handicap, of nationality Beninese and at least 15 years old. They are then divided into three groups: of 10 obese pregnant women, of 10 no obese pregnant women and 10 no pregnant women (reference group). The analysis of variance of the parameters of study obtained by the method of Jensen are compared between them with 12th, 24th and 36th weeks of pregnancy; by the statistical test of Student for matched samples. The values are considered significantly identical to the threshold 5%. Whatever is the group of the pregnant women, the results revealed of significant difference between the three quarters of pregnancy, with regard to the MC, the IMC, the mass, the volume and the mass center of the abdomen. On the other hand, there is no significant difference on the level of the size, then segments: head, neck, four members and top of the trunk; relative with their mass and center of mass. The method used here makes it possible to obviously appreciate the repositioning of the center of mass at a pregnant woman at the various stages of development of the future baby.
