AIM: In the present study, we aimed to compare and examine the relation of different methods to estimate maximal aerobic speed (MAS) with the performance of recreational/amateur runners.
METHODS: Twenty-one male recreational/amateur runners (maximal oxygen uptake [VO2max]: 54.0±7.6 mL·kg-1·min-1) performed two continuous incremental exercise tests, and six different methods to estimate were obtained for the determination of MAS. In one test, a gas analyzer was used to determine the methods to estimate; in the other test, the gas analyzer was not used and the peak speed (Vpeak) was exclusively determined by using a treadmill. Thereafter, each participant ran once for 10 km and once for 15 km on a 400-m track. The two tests had an interval of at least 48 h.
RESULTS: Among the methods to estimate MAS, we noted that the Vpeak determined without metabolic equipment was better correlated with the 10-km (r=0.77) and 15-km (r=0.75) running performance, and presented the lowest standard error of estimate for these performances (1.26 and 1.32 km·h-1, respectively). Vpeak determined with metabolic equipment was significantly lower than Vpeak measured without the equipment, velocity associated with VO2max (vVO2max) as defined by Billat, and vVO2max as defined by Lacour. Moreover, vVO2max as defined by Lacour was significantly higher than Vpeak determined without metabolic equipment, vVO2max as defined by di Prampero, and vVO2max as defined by Daniels.
CONCLUSION: In conclusion, Vpeak determined without metabolic equipment presented the highest correlation with performance in recreational/amateur runners.
