Summary
Twenty-six young male subjects performed work on a bicycle ergometer at a rate of 640 mKg/min. There were two tests per subject; one used a five-minute work period and the other a ten-minute work period. Oxygen uptake curves were obtained during the work and for seven minutes of recovery. Statistical analysis showed that no true steady state was reached even at this relatively low level of work. The deficit part of the average O2 uptake curve was an almost exact mirror image of the repayment curve. The correlation between the individual deficit and pay-off values of oxygen uptake was found to be significant.
