Background: There are conflicting opinions about the degree of adaptability of the cardiovascular system in delivering the physiological needs in case of severe exercise. Role of the normal cardiovascular system in delivering oxygen to meet the demands of various degrees of exercise has been a topic of considerable debate. One view holds that the cardiovascular system is not normally the most limiting factor in the delivery of oxygen, others hold the absence of structural adaptability to physical training cause of limitation of the cardiovascular system. Methods: Cardiovascular functions were assessed after maximal exercise testing by recording parameters like maximum heart rate, delta heart rate, recovery heart rate and maximum oxygen pulse in two groups' viz., athletes and non-athletes. Results: On studying the differences in cardiovascular functions in two groups of non-athletes and athletes, there was no significant difference in maximum heart rate. The other parameters like delta heart rate and maximum oxygen pulse were on the higher side in trained subjects while the recovery heart rate was significantly lower in the athlete group which was consistently maintained after exercise testing. Based on these findings it is suggested that there is a higher adaptability of the cardiovascular system to the training stimulus in the form of better VO2 max (maximum oxygen consumption), faster recovery of the exercise heart rate, and a lesser risk for cardiovascular mortality as suggested by the higher delta heart rate. |
