Illustration of the incremental, sub-maximal test (above) and ramp test (below) including completion criteria of phase 1 and phase 2 characteristics. Bars represent the duration, running velocity, and treadmill grade of each stage. Blood drop = capillary blood collection, ♀ = starting velocity for female participants, ♂ = starting velocity for male participants, green circle = determined velocity for phase 2 determined in phase 1, RER = respiratory exchange rate, min = minutes. During the incremental test, stages are three minutes each with an increment of 1.5 km/h per step. The ramp test stages last 1 min with a 1.5% increase in slope after each stage
