RESUMO
Background: Cardiovascular fitness refers to the ability of circulatory system to supply oxygen to working muscles during sustained physical activity. Objectives: To determine the cardiovascular fitness (using predicted VO2 max) among young healthy medical students in the age group of 17-19 years. Materials and methods: On the basis of physical activity performed subject were categorized into 3 category light, moderate, vigorous exerciser. Cardiovascular fitness was assessed by using treadmill exercise as per Bruce protocol. Results: Data were analyzed using the paired t-test.Conclusion.it was observed in the study that vigorous exerciser had better cardiovascular fitness than moderate and light exerciser. Conclusion: Students who had more physical activity were having better cardiovascular fitness. Hence, it is suggested that some physical activity should be mandatory in the curriculum of medical education which would help us to maintain cardiovascular fitness and reduce the risk of cardiovascular morbidity and mortality in the long run of their careers.
RESUMO
Background: With the advent of remote culture, we are becoming physically inactive and becoming prone to cardiovascular disease. Exercise is often used to evaluate the function of cardiovascular system. Objectives: The study aimed to assess the cardiovascular response to exercise in young healthy medical students. Materials and methods: On the basis of physical activity performed subject were categorized into 3 category light, moderate, vigorous exerciser. Cardiovascular response was assessed by using treadmill exercise as per bruce protocol. Pulse rate, B.P., E.C.G were recorded before and after undergoing the treadmill test. Results: Data were analyzed using the paired t-test. The resting heart rate and systolic blood pressure was significantly lower in vigorous group of exerciser. During exercise heart rate, B.P. increased significantly during peak of exercise and recovery occurs within 6 min but recovery was faster in vigorous group of exerciser. Conclusion: It was observed in the study that vigorous exerciser had better parasympathetic tone than moderate and light exerciser.
