Modificările parametrilor fiziologici în organismul sportivilor înotători în timpul efortului fizic realizat pe veloergometru

This paper talks about the estimation of the functional indexes (HR, VO2 max.) of the professional swimmers during physical effort on the cycle ergometer. It has been determined the heart rate of the untrained youth, as well as swimmers, during resting state. The average heart rate value over 50 seconds of exertion increased in both groups, but it increased significantly more in untrained young individuals compared to swimmer athletes. The maximum oxygen capacity after 50 seconds of exertion shows higher values in swimmer athletes. At the 5th minute of exertion on the cycle ergometer, the trend of increasing heart rate is more evident in untrained young individuals. The maximum oxygen capacity after 5 minutes of exertion increases in both groups, but athletes show higher values. After 9 minutes of physical exertion, the heart rate reaches its highest values in young individuals from both groups, but in untrained individuals, it presents significantly higher values compared to swimmer athletes. The maximum oxygen capacity at the 9th minute of exertion shows significant values in swimmer athletes. This result characterizes the remarkable adaptive capacity of the cardiorespiratory system. At the 15th minute of exertion, lung vital capacity decrease in both groups of young individuals.
