PROMENE KRVNOG PRITISKA U TOKU TESTA FIZIČKIM OPTEREĆENJEM KOD NORMOTENZIVNIH I HIPERTENZIVNIH REKREATIVACA

Abstract

Background. Arterial hypertension is a leading cause of morbidity in developed countries. It often decreases functional capacities of the cardiovascular system. Changes of pressure during physical exercise are a very significant a prognostic factor. Aim. The aim of this investigation was to assess changes of blood pressure and heart rate during exercise in normotensive and hypertensive men involved in recreational physical activity. Methods. The study included 90 young men (aged 30-40 years) involved in recreation (60 with hypertension, 30 with normal pressure). The bicycle ergometer test was performed after rest, the load increased gradually from 50 to 125W. Blood pressure and heart rate were measured at rest and during the exercise. Results. Systolic and diastolic pressure increased signifi cantly in both groups during the ergometry test, compared to the values at rest. This increase was higher among hypertensive men for every graduation of test load (p<0.05). Heart rate was similar in both groups at rest, but higher values were noted among hypertensive men (p<0.05).
