4.2. Physical Activity and Cardiometabolic Disease Risk Outcomes
weight loss, arterial stiffness
EVENTS, ARTERIAL STIFFNESS
Intervention participants self-reported greater MVPA increases than comparison group participants at both post-intervention assessments. Changes in self-reported energy expenditure followed a similar pattern. Self-reported MVPA changes from baseline to 4 months are comparable to improvements observed in a previous e- and mHealth PA intervention with AA women [Meaningful, though not statistically significant, improvements in cardiorespiratory fitness and blood pressure were observed among intervention participants. The descriptive increase in fitness among PA intervention participants (increase of 1.1 mL/kg/min vs. a decrease of 0.8 mL/kg/min in comparison group) corresponds to a 7–13% decrease in risk for premature mortality [Observed patterns of change for aortic pulse wave velocity, a measure of arterial stiffness and independent predictor of cardiovascular events and mortality [BMI was unchanged throughout the intervention. This outcome was not surprising, as weight loss from PA alone requires participants to engage in substantially more MVPA than levels promoted by the study (i.e., >225 min/week) [
