Abstract
Purpose: The purpose of the study was to determine the aerobic and anaerobic energy contributions during the 1500-m treadmill run in untrained college male and female students. Methods: Ten untrained college male subjects (n = 5) and female subjects (n = 5) (Physical Education and Sports Science program) participated in the study (mean VO2max [ml.kg-'.mm-'] + SD = 46.1 & 4.2 and 36.2 ± 4.2, respectively). The relative energy contribution of the 1500-m treadmill run was calculated using the maximally accumulated oxygen deficit (MAOD) method. Results: The relative contribution of the aerobic energy system of the male and female subjects to the 1500-m treadmill run was 77.6 ± 5 % and 62.4 ± 12.6%, respectively. The female subjects (28.98 ± 2.76 %) had a significantly higher percentage of body fat than the male subjects (1 5.88 ± 5.63 %) (p < 0.05). Performance times for the male subjects were faster (421 .8 ± 47.9 s) than the female subjects (548.8 ± 89.3 S) (p < 0.05).<br><br>Conclusion: The results suggested that the untrained male subjects had a significantly higher aerobic energy contribution than the female subjects during high intensity exercise.
