[Arterial pressure, physical activity and physical work capacity].
A representative population sample was studied to elucidate relationships of arterial pressure (AR) with muscular performance (MP) and arterial hypertension risk factors. Power working capacity (PWCx) was measured by means of exercise tolerance test at rest, under physical loading and after the exercise. The findings were processed using a multivariate step-by-step regression analysis which established independent relations between exercise and postexercise MP and arterial hypertension. In normal and hypertensive males a rise in systolic pressure (SP) after the initial exercise (load 1) was dependent on PWC1 after more intensive exercise (load 2) on relations of MP with heart rate, SP and diastolic pressure (DP). In hypertensive males the SP elevation depended also on the age, B. W. index and heart rate. In normal AP males a DP rise depended on PWC2 and MP, the increment being limited by relationships between MP, DP, heart rate and SP. In hypertensive males the influence of PWC1 is defined through a SP rise after load 1. In normal AP and hypertensive females PWC1 is decisive for a SP rise. In normal AP females growth of DP after load 2 was dependent on PWC2 in relation to heart rate growth after load 2, while in hypertensive females PWC1 resulted in DP elevation after load 1. On comparison of the groups with normal and high AP the degree of AP increment under exercise depended on the relations of MP with heart rate, SP and DP.
