TRAINING INTENSITIES FOR AEROBIC EXERCISE DETERMINED ON UNTRAINED HEALTHY-MEN

The purpose of this study was to determine the aerobic training intens ity from the maximal and submaximal running execise in 21 untrained ad ult men. To accomplish this, we evaluated the relationship between phy siological (oxygen intake and heart rate) and physical parameters (run ning speed) of training intensity, and determined the training intensi ty at the submaximal exercise. Oxygen intake and heart rate were measu red by a treadmill test. The maximal oxygen intake (VO2 max), and the aerobic threshold (AerT) and anaerobic threshold (AT) were measured to determine respiratory gas exchange. Running capacity was measured by a 12-min running and treadmill test. For the maximal exercise, there w as a significant correlation (r=0.88, P < 0.01) between VO2, max and l a-min running distance (speed). In addition, the oxygen intake and hea rt rate at AerT and AT in the submaximal exercise were linearly correl ated with running speed. Three levels of training intensity at the sub maximal exercise were termed: light, moderate, and heavy. Since AerT w as the lower limit intensity and AT was the upper limit, we took the m iddle of their values as the moderate intensity. The end point for the determniation of the training intensity at the submaximal exercise wa s estimated to be 85% VO2 max and 180 beats . min(-1).
