Adaptation Of 1st And 4th Year Female Students To Mental Load Based On Pulsometry Data And Heart Rhythm Variability

This paper deals with the peculiarities of the physiological adaptation of the 1st and 4th year female students to mental load at the beginning and at the end of the academic week based on the functional indices of autonomous and central mechanisms of the regulation of the heart rhythm (HR). It was found that the load applied on Monday led to an increase in sympathetic activity in first-year students, and on Friday increased the tension of both parts of the autonomic nervous system that affect the HR. All female students showed a decrease in their stress index associated with an increase in subcortical and parasympathetic activity with a decrease in central control of HR regulation. The pronounced sinus arrhythmia, moderate and pronounced impairment of automatism contribute to the maladaptation of female students and determine the development of body fatigue by the end of the week in freshmen, and during the week in fifth-year students.
