Our article is devoted to the study of the state of the cardiovascular system in female students after the use of different doses of caffeine. Drinking 200 mg of coffee leads to a significant increase in heart rhythm and diastolic blood pressure in girls. The maximum values of heart rate (HR) and blood pressure are reached 1 hour after caffeine intake. Thus, in this case, reported is an increase in the heart rhythm by 12.7% (P ˂ 0.05), a rise in the high blood pressure by 8.8% and that in the low blood pressure level by 12.0% (P ˂ 0.05), as compared to the respective initial values thereof. After drinking 100 mg of coffee, there are no significant changes in the indicators of the cardiovascular system performance recorded: an increase in the heart rate after 1 hour has been reported to be 9.5%, a rise in the systolic blood pressure (BPs) has reached 5.0% and that in the diastolic one (BPd) 6.4%, as compared with the values of the reference group. The use of different doses of caffeine does not lead to significant changes in the duration of the waves and segments on the electrocardiogram. 3 and 6 hours after drinking coffee, the indicators of the cardiovascular system are gradually decreasing, approaching their respective initial values.
