An interventional study of Experimental group using BumptUp mobile exercise app in Cardiovascular (CV) Risk and Exercise, sponsored by Old Dominion University. Recruiting at 1 site in United States. Open to female participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-09-10.

The goal of this study is to determine the effectiveness of a mobile exercise app in improving cardiovascular health and motivation to exercise in pregnant women who are healthy, in their 2nd trimester, between 18-45 years age, and do not do exercise currently. The aims of this study are determine i) the effect of a mobile app (BumptUp) to increase motivation to exercise as assessed by questionnaire, and ii) the changes may occur in cardiovascular health outcomes such as increased percent Flow-Mediated Dilation (FMD), Heart Rate Variability (HRV), and decreased Pulse Wave Velocity (PWV) over an 8-week period of intervention. Researchers will compare this to pregnant women who are healthy, in their 2nd trimester, between 18-45 years age, and who will not be using the mobile app (BumptUp) for exercise. Participants who are in the experimental group will be given access to the mobile app (BumptUp) for 8 weeks. Both the control and experimental group will visit the lab for their baseline measurements (study visit 1), followed by two visits at 4 weeks (study visit 2) and 8 weeks (study visit 3) to have their heart rate variability, arterial stiffness (PWV), and vascular function (FMD) assessed. At each study visit, blood pressure, heart rate, height, and weight will also be measured. Additionally, at all three study visits, participants will fill out a questionnaire to determine motivation to exercise.
9,798 studies on the registry are indexed under Motor Activity; 1,910 are open to participants now.
This study's planned enrollment of 50 is below the median of 60 across 8,388 interventional studies indexed under Motor Activity.

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

This group will have access to "BumptUp" mobile exercise app and will be provided with an educational brochure (Exercise during pregnancy)
Behavioral: Experimental group using BumptUp mobile exercise app
This group will have no access to "BumptUp" mobile exercise app and will only be provided with an educational brochure (Exercise during pregnancy)
This BumptUp app has been developed specifically for pregnancy with safety and screening feature. This intervention will be unique since the researchers will evaluate the cardiovascular health outcomes following the 8 weeks of intervention.
Also known as: BumptUp app
Flow mediated dilation
The cardiovascular health via flow mediated dilation (% change from baseline) will be assessed
Time frame: 8 weeks of intervention period
Arterial stiffness
Cardiovascular health will be measured via arterial stiffness determining pulse wave velocity (m/sec)
Time frame: 8 weeks
Heart rate variability
Cardiovascular health will be measured via heart rate variability (msec).
Time frame: 8 weeks
motivation to exercise
Motivation to exercise will be measured via questionnaire
Time frame: 8 weeks
Plan to share: No

Start is estimated for Sep 2025; primary completion for Aug 2027, 22 months later.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's planned 22 months is above that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
