Abstract: Introduction One of the problems to apply complex system theory is the difficulty to understand how different systems of human body or different fractal levels in one system interacts [1]. Adaptation of human body to physical load is an actual task in sports and clinical medicine. Frequently bicycle ergometry test is used to evaluate the functionality of the human body. The aim of work was to evaluate interconnections between some ECG parameters [2] – RR, JT and QRS intervals, to reveal differences in adaptation to load in sportsmen, sprinters (S) and physically inactive (N) groups using new matrix analysis technology. Differences in the changes of the concatenations between intervals (RR;JT) and (RR;QRS) can reveal features of adaptation to load in different groups. Methods The standard stress test method of bicycle ergometry work was used. Only males participated in the experiment that consisted of the provocative incremental protocol where the maximal load was 250 W (50 W/min). The evaluation of cardiovascular system reactions was made with the ECG analysis system “Kaunas – Load”. The investigated contingent consisted of 10 sportsmen, sprinters (S) (M±SD= 20.1±2.23), and physically inactive (N) (M±SD= 22.5±1.7) groups. The analysis of concatenations [2] of these ECG parameters – RR and JT, RR and QRS during 5 minutes of the load and 5 minutes of recovery was made. Results In both groups during the load the concatenation of (RR/JT) was increasing while the concatenation of (RR/QRS) was decreasing. In the observation of groups dynamics observed differences were – the concatenation of (RR/JT) in the group S was increasing higher (M±SD=0.11±0.02) comparing with group N (M±SD=0.08±0.01). The concatenations of (RR/QRS) in N (M±SD=0.42±0.09) group were decreasing more comparing with S (M±SD=0.23±0.07) group. Discussion Interrelation (RR;JT) could be related to activation of body metabolic [...]
