Interrelationship between changes in functional indices of cardiovascular system during the period of recovery after exercise stress test in football and basketball players

Abstract

The aim of the study was to esrablish the peculiarities of changes in the funcctional condition of basketball and football players, likewise non-athletes, during the recovery period after exercise stress test applying the integrated model of evaluation, to reveal the interrelationship between changes in functionbal indices of cardiovascular system. Materials and methods of the study: the sample of the subjects embraced 270 healthy volunteers: 113 men basketball players (MB), 55 men football players (MF), 32 men non-athletes (MN-A), 38 women basketball players (WB) and 32 women non-athletes (WN-A). "Kaunas-krūvis", an computerised analysis system, created at the Institute of Cardiology of Kaunas University ogf Medicine, that is capable of both registering and analyzing the power developed by the subject and 12-leads of ECG synchronically has been used. A short-term provocative research protocol was used. Indices reflecting several basic mutually related systems, i.e. executive, supplying and regulatory systems of the body were registered. Such indices as mean changes in the heart rate, in the duration of JT interval and pulse blood pressure during physical workload and during recovery were analyzed. Results: The ratio of changes in separate systems of the body during recovery is unstable and varied. it is obvious that the ratio of changes in regulatory and supplying systems is not linear and changes its direction at the 2nd min of recovery (the range of chamnges in JT and HR is shown in fig.2). The ratio of changes in supplying and executive systems at the 2nd min of recovery also changed its direction drastically in all groups of the subjects studied (the range of changes in JT and (S-D) is shown in fig 3).
