CHANGING OF CARDIAC PERFORMANCE OF STUDENTS ON DIFFERENT DAYS OF WEEK DURING THE SEMESTER
We have been studying the indicators of the circulatory system (systolic pressure, diastolic pressure, cardiac rate, pulse pressure and cardiac output) of secondary school students of both sexes under conditions of study load in a form of hands-on training before and after lessons on different days of week in the beginning and in the end of the semester. Age of participants was between 18 and 20. While analyzing of the results we found sexual and circaseptal peculiarities of response of the circulatory system to the study load. We discovered that during the week after study load there is a decrease of arterial pressure, especially in girls, and furthermore these changes are more expressed in the first part of the week. These results are evidence of tiredness’ developments and of lowering of adaptive process of students which need to take into account when drawing up the class schedules and planning the study load.
