||Comparison between maximal lactate steady-state, critical power and the second ventilatory threshold detected by a computer algorithm
||The exact determination of the anaerobic threshold is indispensable in the analysis and optimization of endurance performance, as it demarcates the bodies’ boundary from a predominant aerobic to a predominant anaerobic energy metabolism. In the past, several biological parameters and determination concepts have been proposed to be more or less effective in determining the anaerobic threshold (Peinado, Rojo, Calderon & Maffulli, 2014). Unfortunately most of these concepts are limited by its subjective methodology. In recent years the critical power (CP) concept (Monod & Scherrer, 1965) has received increasing attention and is used alternatively for the anaerobic threshold (Bosquet, Larrouturou, Lheureux & Carter, 2011). However it remains questionable if this concept can be used as an alternative to other lactate threshold concepts. Furthermore it is expected that a more standardised and objective procedure in the determination of the second ventilatory threshold could lead to an improved validity when comparing it to the gold standard method of anaerobic lactate threshold determination.
Therefore, the aim of this study was to determine the second ventilatory threshold (VT2) by an automated method as well as CP by three cycle ergometer tests and to compare them to the maximal lactate steady-state (MLSS).
