lactate_curve {lactater}

Lactate curve

Description

It retrieves the lactate curve for plotting purposes.

Usage

lactate_curve(
  .data,
  intensity_column,
  lactate_column,
  heart_rate_column,
  fit = c("3rd degree polynomial", "4th degree polynomial", "B-spline"),
  include_baseline = FALSE,
  sport = c("cycling", "running", "swimming")
)

Arguments

.data

The raw data.

intensity_column

The name of the intensity column.

lactate_column

The name of the lactate column.

heart_rate_column

The name of the heart rate column, if applicable.

fit

The fit you would like to use for plotting the lactate curve. Options are ⁠3rd degree polynomial⁠, ⁠4th degree polynomial⁠, or B-spline.

include_baseline

A boolean to indicate whether to include the baseline value in the fit.

sport

The sport at which the incremental test was performed. One of cycling, running, or swimming.

Value

a list with the following elements:

data

a tibble containing the raw data with the columns intensity, lactate, and heart_rate.

lactate_curve

a tibble containing the data with the columns intensity and lactate for plotting the lactate curve according to the fit method chosen.

heart_rate_response

a tibble containing the data with the columns intensity and heart_rate for plotting the heart rate response using the linear method.
