A SINGLE COFFEE BEVERAGE CONSUMPTION EFFECT ON YOUNG UNIVERSITY STUDENTS' (MEN) CENTRAL HEMODYNAMICS AND PHYSICAL PERFORMANCE
The three components results analysis is presented in the article: 28 young men-first-year students', aged 17.46±0.57, socio-economic and medico-biological status, studying at universities in Tyumen, survey; answers to the questions of the Eysenck Personality Questionnaire (EPQ); the effect of a single coffee beverage consumption on central hemodynamics and physical performance according to PWC170 test. When analyzing the young men's responses to the questions of ERQ, there were no significant differences in kinds of temperament and self-esteem level. After performing PWC170 step test and a single consumption of a coffee beverage during a 30-minute observation over central hemodynamics, it was noted that the heart rate after a single consumption of a coffee beverage increases slightly, but goes beyond the physiological normative values; systolic blood pressure (SBP) and pulse pressure (PP) indicators change synchronously, but are within the physiological norm. Diastolic blood pressure indicators (DBP) do not change, indicating a good functional capability of arterial vessels. It was revealed that vegetative regulation is represented by sympathetic influence on the cardiovascular system, which can be traced throughout the study period. The stroke and minute blood volume depend on the heart rate, and simultaneously decrease at. Physical rehabilitation 15 15 minutes, increase at 20 minutes, and then stabilize. A single coffee beverage use does not significantly affect the young men's physical performance.
