The study stresses the meaning of the physiological measures that are obtained with the functional diagnostics devices and how these values can be used in coaching sportsmen. Methods: Hemodynamic monitor was used for monitoring hemodynamics and heart function of athletes (n=305) with different fitness levels. Active orthoclinostatic tests and antiorthostatic tests with passive body position changing were carried out with hemodynamics measurements recorded. Results: The most informative indicators and indices of heart function for high performance sport and their values at rest were detected. Along with common hemodynamics indicators (HR, SV, CO, EDV, blood pressure, etc.) the possibility of using correlation rhythmogram in coaching was studied. The correlation rhythmogram "cloud" dependence on athletes' fitness level was revealed in transient during active orthoclinostatic test.
Training process in sport imposes high demands on athletes' cardiovascular system. Results of incremental treadmill test revealed that young athletes perform intensive physical work with cardio strain, i.e. at high HR. That is why training for cardiac adaptation should be foreground at the initial stages of sport specialization. Hemodynamic monitoring allows assessing cardiovascular system dynamics in training. The analysis of such indicators as HR, SV, EDV and inotropy (heart contractility) in 30 12-14 year-old crosscountry skiers made it possible to divide them into 3 groups with different training orientation. Group 1 (low aerobic fitness: SV< 70 ml, EDV<110 ml) underwent aerobic training and general exercises. For group 2 (moderate fitness with high inotropy: RHR< 65 bpm, SV>70 ml, EDV >110, inotropy > 45) general and specific exercises were used on crosscountry terrain under HR control (upper limit is 160 bpm). Group 3 (moderate fitness with normal inotropy less than 40%) underwent intermittent training as well. Regular hemodynamic monitoring (once per 3 months) helped individualize training, transferring athletes from one group to another according to the monitoring results obtained, thus avoiding inadequate cardiac adaptation. Incremental tests carried out twice a year proved the effectiveness of the selected health-saving technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
