The present study aimed to examine and compare cardiovascular responses elicited by two different cardiovascular tasks, namely the Harvard Step Test and the 600-yard run. Ten male postgraduate residential students of the University of Kalyani, aged between 20 and 25 years, were randomly selected as subjects. Resting and post-exercise heart rate, systolic blood pressure, and diastolic blood pressure were measured following both exercise protocols. Data were collected on two separate days, and statistical analysis was carried out using the t-test at the 0.05 level of significance. The results revealed a significant increase in post-exercise heart rate following the Harvard Step Test, while the increase after the 600-yard run was not statistically significant when compared with resting values. Diastolic blood pressure did not show significant changes following either task. A significant rise in systolic blood pressure was observed after the 600-yard run. Furthermore, a significant difference in post-exercise heart rate was found between the two exercise tasks. The findings indicate that cardiovascular responses vary according to exercise modality and intensity and support existing theories of central cardiovascular regulation during dynamic exercise.
