S = increase in speed; I = increase in inclination; INC = incremental test; GXP = step test; INDXP = open individual protocol. |
a p < 0.01 in comparison to the corresponding values for all of the ramp tests (INCs+I, INCS, INCI, INDXP). |
b p < 0.05 for INCs versus INCI, INCS+I versus INDXP and INCS+I versus INCI. |
c p < 0.01 for the GXP versus all ramp tests, INCS versus INDXP and INCS+I, and INCI versus INDXP and INCS+I. |
d p < 0.05 for INDXP versus INCS+I. (RER = respiratory exchange ratio, RPE = rating of perceived exertion). |
