Peculiarities of Central and Peripheral Changes at Onset of Dosed and Maximal Exercise Tests
Research background and hypothesis. Since varying types of physical workloads activate different physiological
system activity at different degree, during dosed and maximal exercises the total effects can highlight the properties of
central and peripheral mechanisms and reveal significant synergies between the central and peripheral cardiovascular
Research aim was to determine the peculiarities of central and peripheral indices of cardiovascular system while
performing dosed and maximal exercise tests.
Research methods. Two groups took part in the study – sportsmen-sprinters (16) and sportsmen – endurance
group (11). The participants of the study performed Roufier exercise and 30 s maximal jump test with maximal
efforts. The 12-leads ECG was registered continuously and the changes of heart rate (HR), JT interval and ratio JT/
RR were analysed. Near-infrared spectroscopy was employed for continuous registration of the changes in oxygen
saturation (StO 2 ) and arterial blood flow.
Research results. The results obtained during the study showed increasingly changing ECG indices while
performing exercise load in both athlete groups but there was no statistically significant difference between groups
while performing maximal exercise, thus oxygen saturation and arterial blood flow was statistically significantly
faster and decreased more in sprint athlete group.
Discussion and conclusion. Dosed and maximal exercise test indicated the peculiarities of cardiovascular
function of athletes, although more differences between individual peculiarities of athletes can be revealed while
performing a dosed exercise test and still more differences – while the maximal exercise tests are performed and
during the recovery after exercising.
Keywords: dosed and maximal exercise test, cardiovascular system, endurance, sprint.
