Abstract [eng] One of the molecular mechanisms, which is a key component of the cardiovascular system functions regulation and determine its capacity or even development some of diseases – the renin-angiotensin system, within on of the proteins encoded by angiotensin-converting enzyme (ACE) gene. The aim of this study was to investigate the relation of different age athletesÿ the ACE I/D polymorphism to the functioning of their cardiovascular system during exercise workouts. Genetic and cardiovascular function researches in athletes were performed. DNA was extracted from peripheral blood cells and the ACE genotypes were identified by polymerase chain reaction (PCR) method. Standard 12-lead ECG and arterial blood pressure were registered during two exercise tests (of aerobic and anaerobic type). The results obtained during the study showed that in athletes of the II genotype subgroups were registered the less changes in heart rate and arterial blood pressure, in duration of JT intervals during booth exercise tests. JT/RR ratio indices differed during aerobic type of workout only. The highest values of this index were registered in both athletes groups in DD genotype subgroups, however recovery rate of this index were considerably slower comparing it to another two groups. The recovery of cardiovascular functional indices in both groups was slower in DD genotype subgroups. The study results suggest that genotype is an important egzogenous factor having influence on the speed of recovery of cardiovascular indices.
