Mobile app to boost cardiovascular health and exercise motivation during pregnancy

The Role of Mobile Apps in Promoting Cardiovascular Health and Motivation to Exercise During Pregnancy

Not applicable Interventional Old Dominion University · NCT07166822

This trial will test whether using the BumptUp mobile exercise app for eight weeks helps healthy pregnant women in their second trimester increase motivation to exercise and improve cardiovascular measures.

What this trial studies

Healthy, sedentary pregnant women at 20-24 weeks gestation who are 18-45 years old will be assigned to either receive access to the BumptUp exercise app for eight weeks or to a comparison group that does not use the app. Both groups will attend baseline and follow-up lab visits where researchers will measure motivation with questionnaires and objective cardiovascular outcomes including flow-mediated dilation (FMD), heart rate variability (HRV), and pulse wave velocity (PWV). The intervention is delivered via the participant's smartphone and targets increases in habitual physical activity and exercise motivation. Outcomes after the eight-week period will be compared between the app and non-app groups to see if the app produces measurable changes.

Who should consider this trial

Good fit: Ideal candidates are English-speaking, generally healthy pregnant women aged 18-45 with a single pregnancy at 20-24 weeks who are sedentary (under 90 minutes of exercise per week), own a smartphone, and are under routine prenatal care.

Not a fit: Women with diagnosed cardiovascular or metabolic disease, significant musculoskeletal injury, on medications that affect vascular function, with multiple gestation, or who are already regularly exercising are unlikely to gain benefit from this intervention.

Why it matters

Potential benefit: If successful, the app could increase pregnant women's motivation to exercise and produce measurable improvements in vascular health during the second trimester.

How similar studies have performed: Prior mobile-app and prenatal exercise interventions have shown some success increasing activity and motivation, but objective improvements in FMD, HRV, and PWV during pregnancy remain largely untested.
