Regular exercise during pregnancy and after childbirth benefits both mother and child by reducing risks of conditions like gestational diabetes, excessive weight gain, hypertension, preeclampsia, depressive symptoms, urinary incontinence, back pain, and complications during labor. This research evaluates two exercise programs—high intensity interval training (HIIT) and moderate intensity continuous training (MICT)—to compare their effects on biological, functional, and psychological health markers in pregnant women and their children. The study also includes nonpregnant women as comparison groups to analyze broader health outcomes. Pregnant women in the study will be randomly assigned to one of three groups: a HIIT program, a MICT program, or an educational program about healthy lifestyle and physical activity. Both exercise programs involve structured cycles lasting 8 weeks during pregnancy and continuing postpartum, with sessions three times a week, either in person or online. Nonpregnant women will participate in similar HIIT or MICT programs over an eight-month period followed by additional cycles. The educational group will receive online sessions on healthy lifestyle topics throughout the study. Participants will be monitored through various assessments at each trimester, during the postpartum period, and up to one year after childbirth. Researchers will measure changes in heart rate, blood pressure, blood glucose, body composition, muscle activity, psychological scores, and childbirth outcomes. Data on children’s growth and health will be collected up to six years of age. The study includes detailed tracking of physical performance, mood, pain tolerance, and other health parameters to understand the effects of these exercise programs on mothers and their offspring.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Up to delivery (varies by pregnancy length)
Pregnant participants in the exercise groups participate in 8-week cycles of either high intensity interval training (HIIT) or moderate intensity continuous training (MICT). Sessions occur three times a week, each lasting 60 minutes and tailored to individual capabilities, continuing until the day of delivery.
3 exercise sessions per week
Duration - Until delivery
Pregnant participants in the standard care group receive routine obstetric care and attend educational sessions on healthy lifestyle and pregnancy-related topics conducted online at least every two weeks.
Online educational sessions at least once every two weeks
Duration - Up to 1 year postpartum
After birth, women who participated in exercise groups engage in 3-month cycles of HIIT or MICT from postpartum readiness up to one year postpartum, with sessions conducted in-person or online depending on circumstances.
At least weekly exercise sessions
Duration - Up to 1 year postpartum
Pregnant participants in the standard care group continue attending online educational sessions on healthy lifestyle and motherhood topics at least every two weeks until one year postpartum.
Online educational sessions at least once every two weeks
Duration - 20 months
Nonpregnant participants in the exercise groups take part in 8-week cycles of HIIT or MICT, three times a week, for 8 months followed by 3-month cycles continuing for an additional 12 months. Sessions last 60 minutes and are tailored to individual capabilities.
3 exercise sessions per week for first 8 months; then ongoing sessions during 3-month cycles
Duration - 20 months
Nonpregnant participants in the standard care group receive routine health care and attend online educational sessions on healthy lifestyle and preparation for pregnancy at least every two weeks for 20 months.
Online educational sessions at least once every two weeks
