Key result
Nine regression-based computerized methods for determining the ventilatory threshold showed significant variance (P<0.001), with estimates ranging from 67% to 90% VO2max.

Methodological variance cautions against interchangeable use of regression-based ventilatory threshold estimates; leaves open the need for standardized protocols.

Do different regression-based computerized methods for determining the ventilatory threshold agree in young and healthy volunteers?
p-value: p=<0.001
Substantial differences exist between regression-based computerized methods for determining ventilatory threshold, challenging the reliance on any single method and highlighting the need for a standardized protocol.
Ekkekakis et al. (2008) conducted a cross-sectional in Healthy (n=60). Regression-based computerized methods for determining ventilatory threshold was evaluated on Variance among methods for determining the ventilatory threshold (p=<0.001). Nine regression-based computerized methods for determining the ventilatory threshold showed significant variance (P<0.001), with estimates ranging from 67% to 90% VO2max.
