Fourteen healthy, recreationally active individuals (11 men, 3 women) participated in a familiarization and two experimental laboratory visits. For both lab visits, a treadmill-based SPV was performed. In one of these SPVs, an aggressive pacing strategy was used; in the other, a conservative strategy was implemented. [Formula: see text], HR, [Formula: see text], [Formula: see text] and RER were recorded and compared between conditions.
There were no differences in [Formula: see text] between the conditions [aggressive 58.8 ± 8.8 ml kg-1 min-1 (mean ± SD), conservative 58.3 ± 7.9 ml kg-1 min-1; p = 0.548]. There were also no differences in HR, [Formula: see text], or [Formula: see text] between the pacing strategies. There was a significantly higher RER found in the aggressive (1.25 ± 0.09) compared to the conservative (1.18 ± 0.07) strategy (p = 0.040).
The pacing strategy that is implemented in the last 2 min of an SPV on a treadmill does not affect the maximal oxygen consumption that is elicited during that test. Either pacing strategy can be used for this protocol without compromising the results, when [Formula: see text] is the variable of interest.
