| Abstract [eng] |
The aim of study was to investigate the changes in parameters that characterize the functional condition of human organism of basketball, soccer players and persons without sport activity at every minute of recovery process.Two groups of women were investigated: BW group — 38 basketball players, NW group — 32 person without sport activity and 3 groups of men: BW group — 113 basketball players, FM group — 55 soccer players, NM group — 32 persons without sport activity.There are a lot of situations when we need to evaluate features of organism reactions to load. According to physiologic changes in human organism during load, the main systems responsible for the functioning of the organism could be working muscles, cardiovascular system is responsible for the energy supply, lungs — for oxygen supply, and the coordination all those systems functioning together is the regulatory system. Two responsible supply systems — cardiovascular and respiratory systems — could be joined into one supplying system.“Kaunas—Load”, an automatized ECG analysis system, created at the Institute of Cardiology of Kaunas University of Medicine, that is capable of both registering and analyzing the power developed by the subject, 12 leads of ECG and arterial blood pressure synchronically, has been used for evaluating the functional condition of the human body. The subject did a computer-based bicycle ergometry test. A short-term provocative protocol was used. The initial power of the load applied to everybody was 50 W and it was increased for healthy NW by 25 W every minute, and by 50 W for others till submaximum power developed. Changes of systolic arterial blood pressure — S, heart rate — HR, JT interval — JT, ratio of interval JT and RR — JT / RR, ratio of pulse amplitude and systolic arterial blood pressure — (S–D) / S were estimated every minute of recovery. The duration of the recovery process was fi ve minutes. Research results suggest the following conclusions: 1. Investigated functional parameters had the different recovery speed. 2. The dynamics of recovery was different in the investigated groups. |
