Prehypertension in Young Active Adults: Initial Vascular Changes
Overview
This study investigates early vascular changes in young, physically active adults with prehypertension and evaluates the accuracy of exercise intensity prescription methods.
Background
Prehypertension is a significant precursor to cardiovascular disease. Understanding its impact on young, active adults is important, as early vascular dysfunction can lead to health risks.
Data Highlights
Parameter
Normotensive (n=26)
Prehypertensive (n=25)
Aortic Pulse Pressure
Lower
Higher (p < 0.001)
Carotid–Femoral Pulse Wave Velocity
Lower
Higher (p < 0.001)
Maximal Oxygen Uptake
Comparable
Comparable (p > 0.05)
Key Findings
Prehypertensive individuals showed higher aortic pulse pressure and carotid–femoral pulse wave velocity (both p < 0.001).
Aerobic capacity and ventilatory thresholds were comparable between normotensive and prehypertensive groups (all p > 0.05).
Fixed relative intensity anchors had limited accuracy in estimating exercise-intensity domains, particularly at the first ventilatory threshold (VT1).
Population-derived % anchors had the lowest estimation error at VT1, while %HRmax anchors showed the best agreement at VT2.
Prehypertension is associated with early central vascular alterations.
Clinical Implications
The findings indicate vascular changes associated with prehypertension in young adults, even when aerobic capacity appears normal.
Conclusion
Prehypertension in young, active adults is linked to early vascular changes.
