[Testing of arterial hypertension with physical exercise PWCx ]

The relation of physical fitness (PF) to blood pressure (BP) and arterial hypertension risk factors was studied in a representative sample by PWCX exercise testing. The relations were studied at the initial stage, during exercise and recovery by using the multivariance stepwise regression analysis. This complex approach allowed the independent relation of PF to BP to be found. In normotensive males, systolic BP determined 4% PF variability after the first exercise, while in hypertensive males, the second exercise heart rate and age determined 27 and 9% PF variability, respectively. In normotensive females, the first exercise heart rate determined 62% PF variability, in hypertensive females, the second exercise systolic BP and age determined 4 and 2% PF variability, respectively. The value x shows the relation of PF to heart rate and BP in the restorative period and is an additional significant parameter of PF and the functional status of the cardiovascular system.
