Brief Summary:
An estimated two-thirds to three- quarters of women experience gestational weight gain outside of IOM's 2009 recommendations: 40-60% of women experiencing excessive gain and 15-30% inadequate gain. Not gaining the adequate weight gain is strongly associated with several maternal and fetal complications..

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: Exercise group Behavioral: Exercise group

The physical conditioning program included a total of three 50-55 minute sessions per week. Pregnant women started at 9 weeks and finished at 38-39 weeks, therefore, an average of 85 training sessions were planned for each participant. All subjects wore a heart rate (HR) monitor (Polar FT7, Finland) during the training sessions to ensure that the exercise intensity was light to moderate.

Each session included 10 min of warm up and 10 min of cool down which included an specific pelvic floor muscles training. The core section of the exercise session lasted from 25 to 30 min and included moderate-intensity aerobic exercises once a week and resistance exercises twice a week.

No Intervention: Control group
Sedentary pregnant women
