Abstract:
Anaerobic threshold (AT) and maximal oxygen uptake (Vo_2max) were determined according to ventilation and gas exchange measurements during graded cycling in 26 athletes and were compared with cardiac condition and function measured by 2-dimensional echocardiography exercise test in corresponding with HR at and above AT. There are significant correlations between Dd and VO_2max and between cardiac function (such as SV, CO, UMO and so on) and VO_2, but the correlations are higher in the same than in different subjects of the same HR. It suggests that the physiological individualities including cardiac function and other peripheral factors are so different that the VO_2max, AT, cardiac condition and function should be measured respectively to evaluate aerobic capabilities of each athlete, thus guiding the training and selection of athletes.
