RESUMEN
Relationships between cardiovascular response to isometric exercise, anthropometric data, and urinary sodium excretion were examined a group of 80 young males aged 19.7 +/- 1.3 years. Diastolic blood pressure (DBP) was well correlated with the anthropometric data both at rest and during hand grip (HG). During hand grip even the systolic blood pressure (SBP) was correlated with height, arm circumference, body weight, and body index. There was no significant correlation between urinary excretion of sodium and BP. The correlation between SBP and some anthropometric measures found during hand grip but not at rest suggests that the sympathetic nervous system may play a role in determining a relationship between excessive body weight and blood pressure increase.
