Were given a nutritional plan to all alike, but only 78 pregnant start a controlled physical exercise plan, the other 74 pregnant are not applied the physical exercise plan.

Results:
Of the 78 pregnant women who underwent to the physical exercise plan 7 suffered backaches, the others 71 had an uneventful pregnancy, only 2 developed gestational diabetes but by external conditions to those treated in this investigation. Of the 74 pregnant women who did not underwent to the physical exercise plan 39 pregnant had a backaches, at different stage of pregnancy, especially in the third trimester, the other 35 did not have complications during pregnancy, but all had a muscle aches.
