ABSTRACT:
The aim of this study was to assess the validity of the multistage shuttle run test in predicting maximal oxygen uptake (VO2max) in athletes trained in sports with different physical demands. Over a 14-day period, 10 male long-distance runners (continuous high-intensity exercise) and 10 male squash players (intermittent high-intensity exercise) performed, in random order, the multistage shuttle run test and a maximal treadmill protocol of increasing elevation which elicited VO2max. Compared with direct measurement of VO2max, the shuttle run test significantly underpredicted the VO2max of the group of runners (n = 10; P is less than 0.01) and of the athletes as a whole (n = 20; P is less than 0.01). The correlation (r) between VO2max determined by the shuttle run test and by the treadmill protocol was 0.61 for the squash players, 0.71 for the runners and 0.67 (P is less than 0.01) for the athletes as a whole. As the subjects represented athletes trained specifically in sports with different physical demands, this may explain why the correlations between the shuttle run test and direct measurement of VO2max are less robust than those reported in previous studies. Furthermore, our results indicate that there are sport-specific differences when predicting VO2max from the multistage shuttle run test.
