lactater (version 0.2.0)

lactate_curve: 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")
)

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.

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.

Examples

if (FALSE) {
lactate_curve(
  .data = demo_data,
  intensity_column = "intensity",
  lactate_column = "lactate",
  heart_rate_column = "heart_rate",
  fit = "3rd degree polynomial",
  include_baseline = TRUE,
  sport = "cycling"
)
}
