Abstract

During a ramp-incremental (RI) cycling exercise, the measurement of oxygen uptake (V̇O2) at the level of the mouth has a time delay from the onset of exercise, which is defined as the mean response time (MRT). It has been shown that the MRT is best calculated using the steady-state V̇O2 from a bout of moderate-intensity exercise prior to the RI test, and then matching this V̇O2 to the time at which this metabolic rate occurs during the RI test. Previous research has used RI slopes of 25 and 30 W∙min-1 to measure the MRT. In this context, it is known that the V̇O2 to work rate relationship is affected by the slopes of the ramp, which might affect the duration of the MRT. However, there is no empirical data to support this assumption.
