95% Confidence intervals in brackets. Coefficient of variation (CV) units are in percent. Absolute reliability is reported as standard error of the measurement (SEM) and minimal detectable change (MDC) use the original units of each parameter. Muscle oxygen saturation (SmO2), heart rate (HR), systemic oxygen uptake (V̇O2), blood lactate concentration ([BLa]), and rate of perceived exertion (RPE).
