The oxygen consumption at rest and after moderate aerobic exercise on a treadmill was estimated in 20 sportsmen of Loyola College, Madras. The mean oxygen consumption index at rest was 118 ml/min./m2 and there was a three-fold increase in oxygen consumption after walking at 5 k.m. per hour for five minutes on the treadmill. The rise in pulse rate and the rise in systolic blood pressure after the exercise did not have any significant correlation with the excess oxygen consumption. However, the product of the rise in pulse rate and the rise in systolic blood pressure (double product) showed a significant correlation with the excess oxygen consumed. The excess minute ventilation showed a positive correlation with the excess oxygen consumed, whereas the PO2 difference between the inspired and expired air showed a negative correlation. It is suggested that after moderate aerobic exercise in sportsmen, the initial response is more on the respiratory system rather on the cardiovascular system.
