Many studies have been supporting the positive effects of an active lifestyle concerning the prevention and treatment of pregnancy-related complications and health problems, such as gestational diabetes, gestational hypertension, obesity, low back pain, urinary incontinence, anxiety or depression, as well as regarding its effectiveness in maintaining fitness and functionality, and in improving postpartum recovery.
Practice and clinical guidelines have become increasingly popular tools for synthesizing evidence-based information to assist practitioners and patients/participants in making decisions related to starting or continuing physical activity.
Despite this knowledge, most women still do not receive proper guidance on how to exercise during pregnancy or after childbirth, and the prevalence of physical inactivity is still high among pregnant and postpartum women. On the other hand, the COVID-19 pandemic has highlighted the need for virtual approaches in health interventions, but few studies have addressed the effectiveness of such interventions.
This study is about the benefits of exercising during pregnancy in terms of maternal physical activity, fitness, and healthy lifestyle parameters. After the first visit to the doctor, pregnant women without absolute contraindications to exercise will be invited to participate in a multi-site (fitness center, university, or hospital) prenatal exercise program delivered either in person or online by qualified exercise physiologists.
The exercise intervention will follow international evidence-based guidelines. It includes aerobic, coordination, strength, postural, stretching, and pelvic floor exercises, organized in two weekly sessions lasting 60 minutes each.
Pregnant women will be asked to answer questionnaires about physical activity, fitness, and healthy lifestyle parameters (sleep, diet, stress) twice: before starting the exercise program and after completing 12 weeks of the program. The same procedure applies to basic fitness field tests (e.g., to assess balance, flexibility, strength, cardiorespiratory fitness, etc.).
Participants will have access to the free Active Pregnancy Guide (including recommendations for walking, dancing, swimming, etc.). On other days of the week, they can follow specific workouts on the YouTube channel (@GravidezAtiva-ActivePregnancy).
Researchers will test whether the exercise program is beneficial in maintaining or improving maternal physical activity and fitness levels and healthy lifestyle parameters after 12 weeks. Moreover, researchers will compare which exercise mode (in-person or virtual) is better or similar. Participants will also be asked about their satisfaction with the intervention and educational resources. Participation and resources will be free. All participants will benefit from the exercise intervention.
The study's results will contribute to knowledge on this topic, inform future exercise recommendations for pregnant women, and inform public health strategies.
Scientific studies have been supporting the positive effects of an active lifestyle concerning the prevention and treatment of pregnancy-related complications and health problems, such as gestational diabetes, gestational hypertension, obesity, low back pain, urinary incontinence, anxiety or depression, as well as regarding its effectiveness in maintaining fitness and functionality, and in improving postpartum recovery.
Practice and clinical guidelines have become increasingly popular tools for synthesizing evidence-based information to assist practitioners and patients/participants in deciding to start or continue physical activity.
Despite this knowledge, most women still do not receive proper guidance on how to exercise during pregnancy or after childbirth, and the prevalence of physical inactivity is still high among pregnant and postpartum women. On the other hand, the COVID-19 pandemic has highlighted the need for virtual approaches in health interventions, but few studies have addressed the effectiveness of such interventions.
This trial will compare the effectiveness of in-person versus online supervised prenatal exercise programs on improving maternal physical activity, functional fitness, healthy lifestyle parameters, and health outcomes. After the first visit to the doctor, pregnant women without absolute contraindications to exercise will be invited to participate in a multi-site (home, fitness center, university, or hospital) prenatal exercise program delivered either in person or online. The study will be conducted in multiple centers, recruiting women between 13-20 gestational weeks, allocated to in person or online exercise groups for 12 weeks. The exercise intervention will follow international evidence-based guidelines. It includes aerobic, coordination, strength, postural, stretching, and pelvic floor exercises, organized in two weekly sessions lasting 60 minutes each. All sessions will be supervised by qualified exercise physiologists.
Assessments include validated questionnaires (PPAQ, IFIS, etc.) and fitness tests, at baseline and post-intervention. Pregnant women will be asked to answer questionnaires about physical activity (PPAQ), fitness (IFIS), and healthy lifestyle parameters (health, sleep, diet, stress) twice: before starting the exercise program and after completing 12 weeks of the program. The same procedure applies to basic fitness field tests (e.g., to assess balance, flexibility, strength, cardiorespiratory fitness, etc.). All tests will be applied by qualified exercise physiologists.
Demographic data (age, BMI, gestational age) will be described using frequencies and percentages for categorical variables. Descriptive statistics (mean, standard deviation, median, interquartile range) will be used to summarize baseline characteristics of participants in both groups (IN and ON). Descriptive and inferential statistics will be applied to all outcomes. Comparative analysis of IN vs. ON interventions will be conducted using intention-to-treat and per-protocol approaches. Comparative analysis will be used to compare changes in primary (physical activity, health-related, and functional fitness) and secondary (lifestyle parameters) outcomes between IN and ON groups over time (baseline and post-intervention). Subgroup analyses will evaluate potential differences regarding maternal age groups (20-34 years vs. 35-50 years). Adjustments will be performed for potential confounders (e.g., maternal age, baseline fitness levels). The significance level of 0.05 (alpha level) will be set for all statistical tests. Power calculations were performed to ensure the study is adequately powered to detect clinically significant differences between groups. For categorical variables, comparative analysis will be performed using chi-square tests or Fisher's exact tests.
Regarding additional outcome analysis, the evaluation of interventions and resources will be performed by means of descriptive analysis summarizing the usage and satisfaction with resources (Active Pregnancy Guide, Active Pregnancy YouTube channel, and Active Pregnancy app) and satisfaction with exercise interventions.
The statistical software SPSS will be used for data analysis. The study has obtained ethics approval from relevant institutional boards. All participants will be informed about the benefits and objectives of the study. Participation in the exercise programs and assessments is free, and they can leave any time without any consequences. Exercise interventions will be supervised and delivered by qualified exercise physiologists and medical records will be obtained by medical doctors. All educational resources will be available for free. Participant confidentiality will be maintained.
Participants will have access to the free Active Pregnancy Guide (including recommendations for walking, dancing, swimming, etc.). On other days of the week, they can follow specific workouts on the YouTube channel (@GravidezAtiva-ActivePregnancy).
Participants will also be asked about their satisfaction with the intervention and educational resources. Participation and resources will be free. All participants will benefit from the exercise intervention.
The study's results will contribute to knowledge on this topic, inform future exercise recommendations for pregnant women, and inform public health strategies.
