VO2max = maximal oxygen uptake; VO2@LT = VO2 at the lactate threshold; VO2@OBLA = VO2 at the onset of blood lactate accumulation; %VO2@LT = percent of VO2max at the lactate threshold; %VO2@OBLA = percent of VO2max at the onset of blood lactate accumulation; [La]PEAK = peak of lactate; HRMAX = maximal heart rate; HRLT = heart rate at the lactate threshold; HROBLA=heart rate at the onset of blood lactate accumulation; %HRLT = percent of heart rate at the lactate threshold; %HROBLA = percent of heart rate at the onset of blood lactate accumulation; vVO2max = velocity associated with VO2max; PV = peak velocity; vLT = velocity at the lactate threshold; vOBLA = velocity at the onset of blood lactate accumulation; ES = effect size.
