Where ∆VO2max = change in VO2 over the final two consecutive 30 s sampling periods, ∆ VCO2 = change in VCO2 during the final two consecutive 30 s sampling periods, RERmax = respiratory exchange ratio obtained at VO2max, VEmax = minute ventilation at VO2max, GET% VO2max = gas exchange threshold expressed as a % VO2max, HRmax = heart rate recorded at VO2max, BLamax = blood lactate concentration recorded at the point of volitional exhaustion, Wmax = power output derived at volitional exhaustion. |
