WR |
a numeric vector of work rate values. Typically these would be the work rates associated with stages in an incremental exercise test. |
La |
a numeric vector of blood lactate values (mmol/L) associated with
the stages described in |
sig_rise |
numeric; a rise in blood [Lactate] that is deemed significant. Default is 1.5 mmol/L. |

This function is a slightly modified version of that written by Newell et al. (2007) and published in the Journal of Sport Sciences (see references). The original source code, which also includes other functions for lactate analysis, can be found here.
a data frame of model outputs, and optionally a matrix of plots.
