Impact of exercise on cardiac hemodynamic parameters in students

Functional changes were studied in first-year students performing exercises. Analyzing the findings indicated that a 500-m race caused unidirectional varying changes in young women and young men. The functional systems of the first-year students responded to strenuous exercises due to the tension of cardiac rhythm regulatory mechanisms, which manifested itself as almost 4.5-fold increase in the activity of the sympathetic regulatory circuit. Excessive tension that was a result of long-term inactivity may be further a cause of disproportionally developed cardiac chambers, leading to myocardial hypertrophy, cardiac arrhythmia, weakened valvular apparatus.
