Workloads displayed as mean (SD) %Wpeak. HRT, half-recovery time; n, number of participants with available reoxygenation data; ICC, intraclass correlation coefficient; SEM, standard error of the measurement in seconds; MDC, minimal detectable change in seconds; CV, coefficient of variability for repeated measurements within participants.
