10 Hz Train.Red App export

Description

Exported from Train.Red app, recorded at 10 Hz. Containing two 5-minute cycling work intervals, placed on bilateral vastus lateralis muscle sites. Some data channels have been omitted to reduce file size.

Format

.csv file with header metadata and 10 columns and 11995 rows:

Timestamp (seconds passed)

Elapsed time (s).

Lap/Event

Lap number (numeric).

SmO2

Muscle oxygen saturation, filtered (%). Two channels have duplicated names. If both are called, the second will be renamed to SmO2_1.

SmO2 unfiltered

Muscle oxygen saturation, raw signal (%). Two channels have duplicated names. If both are called, the second will be renamed to ⁠SmO2 unfiltered_1⁠.

O2HB unfiltered

Oxyhaemoglobin concentration, raw signal (arbitrary units). Two channels have duplicated names. If both are called, the second will be renamed to ⁠O2HB unfiltered_1⁠.

HHB unfiltered

Deoxyhaemoglobin concentration, raw signal (arbitrary units). Two channels have duplicated names. If both are called, the second will be renamed to ⁠HHb unfiltered_1⁠.

Channel mapping for read_mnirs():

• nirs_channels = c("SmO2", "SmO2 unfiltered", "O2HB unfiltered", "HHb unfiltered")

• time_channel = c("Timestamp (seconds passed)")

• event_channel = c("Lap/Event")

• interval_times = list(start = c(2150.09, 2872.28), end = c(2452.26, 3167.98))

• interval_times = list(start = c(65.94, 788.13), end = c(368.11, 1083.83)) from zero_time
