Background and purpose: Several studies have indicated that endurance exercise can improve cardiovascular performance, but this has not been observed by conducting resistance exercise. However, the studies regarding the health management of athletes remained limited, particularly in the cardiovascular health. Young athletes often ignore their own health, and some of them would have high blood pressure. Therefore, the present study was aimed to investigate the cardiovascular characteristics during the status of rest and exercise in endurance-type athletes, resistance-type athletes, and their control peers. Our results might provide helpful information for athletes in health management and sports performance. Methods: We recruited 34 male subjects aged from 17 to 22, including endurance-type athletes (n=12), resistance-type athletes (n=12), and the control group (n=10). Endurance-type athletes consisted of long-distance swimmers, resistance-type athletes consisted of weight lifters ranked on the level of 56-77 kg, and the subjects in the control group were healthy men without conducting any exercise training. Heart rate, blood pressure, maximum oxygen consumption (VO2max), heart rate variability, and arterial stiffness index (ASI) were measured for all the subjects in the status of rest and exercise, respectively. The collected data were statistically compared among the three groups. Results: After analyzing the basic information, significant differences were found in body fat and bone mineral density between the athlete and control groups (p&;lt;0.05). In the resting status, the heart rate was lower in the athlete groups than the control group (p&;lt;0.05), but no group difference was found in blood pressure. The ASI in the resistance-type athletes was significantly higher than the other two groups (p&;lt;0.05), while mean NN in the endurance-type athletes tended to be higher than the resistance-type athletes. In the status of exercise, endurance-type athletes had a higher VO2max and exercise time to exhaustion than the resistance-type athletes and control group (p&;lt;0.05). Conclusions: This study demonstrated that some differences existed in the cardiovascular characteristics between endurance-type and resistance-type athletes.
