Abstract
The purpose of this study was to attempt to determine the relationship among selected cardiorespiratory variables in young adult females. The 44 subjects were tested on a bicycle ergometer before and after 10 weeks of conditioning on this apparatus. Maximal oxygen uptake (L/min.) on both the pre- and posttest was positively and significantly related to all of the selected variables except for ventilation equivalent and heart rate measured during rest and maximal exercise. This relationship was considerably reduced when maximal oxygen uptake was corrected for body weight. Total work output (kpm) on the pretest was also positively and significantly related to all other selected variables except for ventilation equivalent and heart rate measures. In general, however, correlation coefficients between selected variables were rather low, suggesting that these measures used singularly would involve considerable error in the evaluation of cardiorespiratory fitness.
