Comparison of two field tests to estimate maximum aerobic speed

Abstract

The measurement of maximal aerobic speed (MAS) and the prediction of maximal oxygen uptake (VO2 max) by means of field tests were carried out on 17 students studying physical education. The subjects underwent a continuous multi-stage track test (Leger and Boucher, 1980), shuttle test (Leger et al., 1984) and PO2 max measurement on a treadmill. The VO2 max values estimated using the track test (56.8 ± 5.8 ml kg-1 min-1) were not significantly different from the values measured in the treadmill test (56.8 ±7.1 ml kg-1 min-1), but were higher than those estimated using the shuttle test (51.1 + 5.9 ml kg-1 min-I). The maximal nature of the tests was checked by measurement of heart rate and lactate concentration, taken within 2 min post-test. The means of the MAS observed in the track test (15.8 + 1.9 km h-1) and in the treadmill test (15.9 + 2.6 km h-1) were not significantly different (P>0.10). The mean of the shuttle test MAS (13.1 + 1 km h-1) was significantly lower (P < 0.01) than those of the other tests. However, the MAS of the shuttle test and track test are linked. The equation for linear regression between MAS values in these two tests is MAStrsck= 1.81 x MASshuttle—7.86 (r=0.91), allowing estimation of one of these MAS values when the other is known. Thus these values may be used within diversified training. © 1994 E. & F.N. Spon.
