This study examined the relationship among three predictive tests of aerobic capacity when analyzed within and across gender. Sixty-three active college students (37 males, 26 females) performed the multistage 20-metre shuttle run (SR), the Canadian Aerobic Fitness Test (ST), and the 1.5-mile run (DR). Predicted VO2max (ml.kg-1 x min-1) scores were obtained for each subject. Significant correlations were found among the VO2max results on all possible pairings of tests analyzed as a group, and by gender (p < .001) except for the females' SR and ST pairing (p > .05). One-way analysis of variance was performed for each of the three subject pools with significant F values for the grouped (F = 5.8, p < .01) and male (F = 30.7, p < .01) samples. Tukey HSD post hoc comparison identified significant differences among the SR and ST, and ST and DR VO2 max scores for both samples. However, there were no significant differences between the cell means when females were analyzed separately.
