This study was undertaken to compare the maximum oxygen uptake obtained by three standard maximal oxygen uptake tests. One indirect and two direct tests of maximum oxygen consumption were chosen. The direct tests chosen were the continuous bicycle test and the continuous treadmill test. The indirect test was the Åstrand-Ryhming test employing heart rate response to submaximal work. -- The sample (N=20) which consisted of 10 male and 10 female volunteer students from Memorial University of Newfoundland was divided into two groups on the basis of sex. Each subject was required to perform each of the three maximum oxygen consumption tests. -- The scores obtained from the maximum oxygen consumption tests were compared using the t test for paired samples. The scores obtained from all three maximum oxygen consumption tests were found to be significantly different at the .05 level in all cases except for the Åstrand Indirect test and the continuous cycling test in female subjects. -- The mean difference between the scores on the cycling test and the treadmill test was 9% for males and 11% for females. The treadmill test resulted in values approximately 7% higher than those for both groups. A difference of approximately 3% was found between the Åstrand Indirect and the cycling test with the former yielding the higher scores in both male and female subjects. -- Spearman's coefficient of rank correlation was used to find the correlation coefficients between the three tests. All correlation coefficients were found to be significant at the .05 level. -- It was concluded that, -- i the treadmill test results in values which are approximately 10% higher than those obtained during the cycling test, -- ii the Åstrand indirect test underestimates the treadmill score by about 7%, -- iii the Åstrand indirect and cycling test give scores which are similiar.
