A STUDY OF CARDIO-PULMONARY EFFICIENCY IN DIFFERENT CATEGORIES OF RUNNERS
2000
Selected short distance runners, middle distance runners and long distance runners were subjected to graded exercise on a treadmill. The maximum aerobic power (V02max) and other indices related to oxygen transport system viz. heart rate, ventilation volume, breathing reserve, dyspnoeic index, 02Pulse and RQ were recorded at respective V02 max work loads, and the values were compared. Long distance runners and middle distance runners showed a significantly higher V02 max than the short distance runners when V02 max was expressed per unit of body weight. Among the endurance runners, long distance runners had a significantly lower resting pulse rate as well as the maximum heart rate during work than the middle distance runners. On comparison, Ventilation Volume, Breathing reserve, Dyspnoeic index, 02 pulse and RQ at V02 max work loads do not differ significantly among different categories of runners.
