Abstract: Background. Functional state can be assessed from the dynamical changes of functional parameters during testing manoeuvres. This study was designed to determine the alteration of cardiovascular parameters and their interactions induced by session of continuous and combined training (CT). Methods. The participants of the study (16 females, previously active athletes) performed two heath training sessions, separated by 7 days. The first session was designed for aerobic training, i.e. 30 min of jogging and the second session was performed as CT, i.e. additionally 4 interval sprint bouts at the end of the same type of running session were added. The table-tilt test (orthostatic probe) was used as the testing manoeuvre before and after the session. Arterial blood pressure measurements and 12-lead ECG were recorded for later analysis by means of computerized ECG analysis system. Dynamics of concatenation between indices was made by use a method based on matrix theory. Two synchronous time series (xn: = 0, 1, 2,..) and (yn: = 0, 1, 2,..), which represent results of measured indices were structured and analysed by using the numerical characteristics of second order matrix and main components of it. From definitions of matrix characteristics the main interest has discriminants of the matrix: disk An = ((xn–yn) 2+4((xn-1–yn-1)*(xn+1–yn+1)) The parameters were interpolated using cubic splines, then discriminants between all investigated relationships were defined. Results. The results obtained during the study showed that after both training sessions a lot of registered cardiovascular indices were changed: increase of heart rate, ST-segment depression, shortening of JT interval, peripheral vascular tone in response to orthostatic increase was slower. The difference between influences of training sessions was more evident on comparison of interactions of cardiovascular indices and their changes induced by exercising. Some [...]
