Abstract
INTRODUCTION: Prediction equations are inexpensive, easy and commonly used to estimate the oxygen consumption (VO2) and caloric expenditure of physical activity, but some of these equations have limitations, including a stated limit of accuracy of the cycling equation up to a work rate (WR) of 200 watts. This is not favorable to trained individuals who can cycle at WR much higher than 200 watts. PURPOSE: To create a VO2 prediction equation for cycling WR below and above 200 watts. METHODS: Twenty nine participants qualified for this study by achieving a maximal WR (WRmax) of at least 300 watts during a maximal graded exercise test (GXT). These individuals then completed two submaximal exercise trials (SXT). During the SXT, steady state VO2 was collected for each WR and was analyzed by linear regression. RESULTS: The 29 participants were 20-54 years old, 1.80 ¿¿¿¿ 0.00 meters tall, weighing 78.29 ¿¿¿¿ 0.44 kg with a body fat of 9.14 ¿¿¿¿ 0.21% and a WRmax of 361.13 ¿¿¿¿ 2.06 watts. According to the analysis of this sample, the data suggests VO2 (ml/kg/min) = {10.941ml/kg/min x (WR (watts) / body weight (kg))} + 4.522 (ml/kg/min) with an R2 of 0.96. CONCLUSION: The regression equation created from this data to predict VO2 is useful to estimate the oxygen consumption and caloric expenditure of trained individuals who cycle below and above 200 watts.
