Does anyone know of a source of software or computer code for the
automatic determination of the ventilatory threshold (VT)?
For example, several papers mention that they used the computerized
method proposed by Beaver et al. in 1986. Has anyone heard of or used
the actual computer program developed by Beaver et al.? Or other
similar programs (e.g., Orr et al., 1982; Dickstein et al., 1990)?
I emphasize that I am not talking about the methods for the
determination of the VT found in packaged metabolic analysis software
programs that ship with various ergospirometry systems (e.g.,
Medgraphics, Cosmed, ParvoMed, etc). These programs do not reveal any
information about the exact methods they use or the details of their
calculations. I am talking about stand-alone (off-line) computer
programs that implement published methods for the determination of
Any help will be greatly appreciated.
