[The relation of physical work capacity to the arterial pressure level and risk factors for arterial hypertension]

A multivariate regression analysis including muscular performance, arterial pressure, age, heart rate, body-weight index permitted identification of independent relations between pressure and muscular performance. The latter accounts for 3% variability in initial systolic pressure in females and for 3% variability in males under physical loading. Initial systolic pressure accounts for 5% variability of muscular performance in females. The dependence between muscular performance and diastolic pressure is indirect, noticeable only in physical load with the help of double product.
