Testing of the ventilatory threshold (VT) and maximal oxygen uptake (VO2peak) is relevant for the evaluation of a range of training studies, clinical trials and cross‐sectional studies. Due to a possible learning effect, a familiarization test is often performed to increase test reproducibility. However, limited research has investigated this learning effect and reproducibility of maximal exercise testing. The most appropriate ways to determine VT and VO2peak are not clear, and this study evaluated two approaches (V‐slope and a combined method) for the determination of VT and five time‐averaging intervals (60, 30, 15, 10 and 5 s) for the determination of VO2peak to compare test results and reproducibility.
