Submaximal Prediction of Maximal Oxygen Uptake by Computer Controled Cycle Ergometer

Twelve young men (aged 20-30 years), 8 middle-aged men (aged 37-49 years), and 10 young wemen (aged 22-31 years) performed submaximal graded exercise test (3 min. x 3 steps) followed by maximal exercise test to measure maximal oxygen uptake (V O_) directly on an electromagnetically braked cycle ergometer. From these submaximal work load and VO_2 values, equations to predict VO_ were described. No significant differences were found between the directly measured VO_ and the VO_ estimated by the protocol and equation described here. The standerd error of estimate ranged 12.1-13.5%
