MFO (version 0.1.0)

MFO: Maximal Fat Oxidation & Fat Max Function

Description

Maximal Fat Oxidation & Fat Max Function

Usage

MFO(
  step_time,
  db_MFO,
  db_basal,
  db_graded = NULL,
  cv_var,
  author,
  VO2max = NULL
)

Arguments

step_time

how often the data was collected (in seconds).

db_MFO

database containing MFO test.

db_basal

database containing basal test.

db_graded

database containing incremental exercise test.

cv_var

variable to estimate coefficient of variation. Can be: VO2, VCO2 or RER.

author

author to estimate MFO. Can be: Frayn or Jeukendrup.

VO2max

VO2max can be passed directly using this argument instead of use db_graded argument.

Value

Returns a list which contains:

• MFO_db: database used to create the MFO plot.

• MFO_plot: ggplot object with the MFO plot.

• MFO: Maximal fat oxidation.

• FAT_MAX: Intensity that elicits MFO.

• x_CHO: carbohydrates in basal metabolism.

• x_FAT: fat in basal metabolism.

• x_Kcal: Kcal in basal metabolism.

Examples

# NOT RUN {
# }
# NOT RUN {
# Get old working directory
oldwd <- getwd()

# Set temporary directory
setwd(tempdir())

# Read dfs
data(list = c("basal_df", "MFO_df", "VO2max_df"), package = "MFO")

# Convert to data.frame
basal_df <- data.frame(basal_df)
MFO_df <- data.frame(MFO_df)
VO2max_df <- data.frame(VO2max_df)

# Calculate MFO and Fatmax
result_MFO <- MFO(step_time = 20,
                 db_MFO = MFO_df,
                 db_basal = basal_df,
                 db_graded = VO2max_df,
                 cv_var = "RER",
                 author = "Frayn",
                 VO2max = NULL)

# set user working directory
setwd(oldwd)
# }
# NOT RUN {
