[A comparative evaluation of 2 physical loading tests in arterial hypertension]

Interrelationships between arterial pressure (AP), physical performance (PP) and arterial hypertension (AH) risk factors were studied in two representative samples of hypertensive subjects using multivariate stepwise regression analysis in the preexercise, exercise and postexercise periods and two exercise tests. Test 1 (standard continuous bicycle ergometry) allowed PP estimation by the work performed and double product (HRmax x SAP/100 max). Test 2 (stepwise intermittent bicycle ergometry by PWCx) estimated PP according to a special formula. Test 1 is standard and therefore is able to provide significant diagnostic, prognostic and rehabilitation information. Test 2 is standard only at its first step, while the second step varies with cardiovascular response to the initial step. This is convenient for definition of permissible exercise dynamic control over exercising subjects, assessment of training efficacy in different regimens and programs. It is concluded that both methods are fit for estimating relations between AP, PP and AH risk factors in exercise and are comparable by the main parameters.
