Study on the cardio-respiratory function and exercise intensity in canoe players

&nbsp;&nbsp;The purpose of this study was to measure the respiratory function with kayak-Ergometer and to and analyze the exercise intensity for each kayak player in 500m canoe race. Subjects were seven well-trained kayak players of a middle school in U city. Control group was composed of seven beginners who were not trained in three months yet. On this study, they (trained and non-trained) were tested by using kayak-Ergometer. According to them, we analyzed the exercise intensity in 500m race by analyzing VO₂max, VO₂max/㎏, HRmax and blood lactate concentration during convalescence and measuring the heart rate in 500m canoe race.<BR>&nbsp;&nbsp;On analysis, we come to a conclusion like this :<BR>&nbsp;&nbsp;1. The study has shown that VO₂max, VO₂max/㎏ and all out time of canoe players were higher (P＜.05) than that of non-trained respectively. There wasn&quot;t a striking difference on VEmax and HRmax between two groups. HRrest during stability of non-trained were higher (P＜.05) than that of trained, but there was not a sharp difference on HRmax.<BR>&nbsp;&nbsp;2. Lactate concentration was not to have a significant difference on rest, after maximal exercise and recovery 2 min. But it is found to have a high significance(p＜.05) to recovery 3 min.<BR>&nbsp;&nbsp;3. During 500m race, intensity of the over 81%HRmax was shown as the highest intensity to 66.7% of all races. Intensity of 71~80%HRmax, 41~70%HRmax and under 40%HRmax amounted to 11.1% of all race.<BR>&nbsp;&nbsp;Putting the above-mentioned together, we can assume that kayak has an influence on VO₂max, VO₂max/㎏, Heart Rate during stability and can improve the recovery of blood lactate density.<BR>&nbsp;&nbsp;And the data have shown that 500m race is an exercise of high intensity to some degree that the 66.7% of it should reguire 81% HRmax or even more.
