Purpose
Brachial blood pressure (BP) is the current gold standard for BP assessment; however, measures of pulse wave velocity (PWV) and central blood pressure (CBP) may contribute uniquely to assessment of cardiovascular health status. As of yet, standards for assessment of CBP and PWV have not addressed the impact of hydration status on proper measurement. To understand the impact of hydration, PWV and CBP should be measured in a euhydrated and hypohydrated state.
Methods
Forty-three young, healthy participants (21 ± 2 years) completed a dehydration protocol utilizing moderate aerobic activity until they lost 1%–2% of their body weight. PWV and CBP were measured before and following the dehydration protocol. Linear regression was utilized to assess change in hydration status and change in PWV and CBP.
Results
No significant relationships were observed between the change in hydration status (% body weight lost) and PWV (β = 0.05, p = 0.78) or central diastolic BP (β = −3.8, p = 0.10), however, a significant relationship was observed with central systolic BP (β = −5.0, p = 0.03).
Discussion
In conclusion, the assessment of hydration status before measurement of CBP or PWV may not be necessary in young, healthy individuals.
