LT: Calculate and plot lactate breakpoint (lactate threshold)

Description Usage Arguments Value References

Description

Calculates workload at the lactate breakpoint. Based on functions described by Newell et al. 2007 (see reference)

Usage

1
LT(data, workload.column = 1, lactate.column = 2, plot = T)

Arguments

data

A data frame with work intensity (e.g. watt) and lactate measurements

workload.column

An integer specifying the column with work intensity data, default=1.

lactate.column

An integer specifying the column with lactate data, default=2.

plot

Logical specify whether to add plot or not. The plot shows data points with the model fit

Value

Work intensity at a specified rise from baseline lactate concentration
