RESUMO
The effect of physical exercises was studied with reference to the content of non-esterified fatty acids (NEFA), cholesterol and beta-lipoproteins, as well as catecholamines and lactic acid in 130 patients with essential and renal hypertension. The control group included 12 normal individuals. The physical exercises were conducted on a bicycle ergometer with a step-wise growth of the load by 150-300 kgm per each 4 min. The value of the maximal tolerated physical load was determined. It was decreasing parallel the progress of the disease. The conducted investigations demonstrated the presence of an inverse relationship between the initial blood level of beta-lipoproteins and cholesterol, on the one hand, and the value of physical load and capacity for work, on the other. The changes in the lipid metabolism parameters are distinctly connected with the activity of catecholamines and lactate concentration.
