Effects of changes in V̇O₂ and VO_2max on MAS

Speed (km h− 1)	V̇O2 (ml·kg−1·min−1)
	Baseline case	Change stage 1	Change stage 2	Change stage 3	Change stage 4	Change stage 5
12.0	39.0	41.0	39.0	39.0	39.0	39.0
13.0	42.0	42.0	44.0	42.0	42.0	42.0
14.0	45.7	45.7	45.7	47.7	45.7	45.7
15.0	48.8	48.8	48.8	48.8	50.8	48.8
16.0	52.3	52.3	52.3	52.3	52.3	54.3

	Delta MAS for a 5% increase in V̇O2max (from 65.0 to 68.2 ml · kg−1· min−1)
MAS (method 2, %)	+ 4.9%	+ 5.4%	+ 5.2%	+ 5.0%	+ 4.7%	+ 4.6%
MAS (method 3, %)	+ 5.0%	+ 5.0%	+ 5.0%	+ 5.0%	+ 5.0%	+ 5.0%

V̇O2max (ml kg−1 min−1)	65	65	65	65	65	65
MAS (method 2, km h− 1)	19.8	20.5 (+ 3.3%)	20.1 (+ 1.2%)	19.7 (−0.6%)	19.4 (−2.3%)	19.1 (−3.8%)
MAS (method 3, km h− 1)	20.0	19.8 (−1.0%)	19.8 (−1.0%)	19.8 (−1.0%)	19.8 (−1.0%)	19.8 (−1.0%)

The different cases at the top present a baseline case and the effect of a change in sub-maximal V̇O₂ of + 2.0 ml･kg^-1･min^-1 at each of the different sub-maximal stages according to method 2 and 3 for determination of MAS. Values in bold are different from baseline case. The bottom of the table shows the relative delta (%) in MAS resulting from a 5% increase in V̇O_2max in each case. As the different cases have different slopes, the changes in V̇O_2max will vary the magnitude of change in MAS when method 2 is used. This is not the case with method 3, where the changes in V̇O_2max are equal in direction and magnitude to the changes in V̇O_2max, as no linear interpolation is used

MAS maximal aerobic speed, V̇O₂ oxygen uptake, V̇O_2max maximal oxygen uptake
