Abstract
Aim: Maximal handgrip strength is a strong predictor of cardiovascular mortality in economically and socioculturally diverse countries, yet the main determinants of cardiovascular response to change in afterload during handgrip are not well known. We examined the blood pressure (BP) responses during submaximal handgrip (at 25% of grip strength) and the determinants of grip strength. Methods: We studied 2215 participants from a population-based random sample without overt clinical disease (Asklepios Study; mean age 56.2 years). Handgrip testing was performed using a modified Jamar dynamometer with direct visual feedback. Simultaneously, a validated finger plethysmographic device measured continuous BP and heart rate. Results: During handgrip, SBP and DBP rose by, respectively, 20 +/- 13 and 10 +/- 6 mmHg. These changes were normally distributed and consistently higher in men. The main independent determinants of mean arterial pressure response during handgrip were: grip strength (F = 191.4; P < 0.001), baseline pulse pressure (F = 32.0; P < 0.001), height (F = 16.4; P < 0.001) and age (F = 12.8; P < 0.001). Grip strength was associated with muscle mass, better metabolic health, but also with higher baseline DBP. There was a significant graded increase in maximum pressure achieved and in the magnitude of pressure change during handgrip with increasing BP categories (P for trend <0.001). Conclusion: The population BP response to handgrip is variable and its predominant determinant turned out to be grip strength itself, which should be accounted for in future analyses. Higher baseline BP, even within the normotensive range, acted as an independent and graded predictor of BP increase during handgrip.
