Abstract

The study was conducted on 17 state level basketball players in National Institute of Sports, Patiala, during the training camps. Each player was examined for V02max, EC02 at various work loads and ventilatory equivalents, on thebicycle ergometer. The role of V02max/kg/min in determining the performance onergometer was revealed by significant correlation between the two parameters (r = 0.85). Early production of EC02 (excess carbon dioxide) in some way or the other was found to limit the ability of an individual to utilize a large fraction of ones aerobic resources. Those who produced EC02 at early stage, did not perform well on cycle ergometer. Another limiting factor of interest in this study was the fitness of the cardio-respiratory systems. The VE1.5L was found to correlate highly with the cycle ergometer performance time and EC02 levels at various work loads requiring different percentages of one aerobic power. So, according to this study, utilization of a large fraction of ones total aerobic resources depends upon the fitness of cardio-respiratory systems, the quantitative production of EC02 and the onset of EC02 production.
