💿 Data: FigShare doi: 10.6084/m9.figshare.23662662
Download the data from the FigShare link above. The following four csv files should be unzipped directly into the /data/ directory.
cohort1_inlab.csv - ECU cohort, in-lab data from treadmill run
cohort1_realworld.csv - ECU cohort, real-world data
cohort2_course.csv - IU cohort, measured course run
cohort2_realworld.csv- IU cohort, real-world run
Device metrics, except speed, are prefixed by the device (hrm or stryd). Speed is enhanced_speed and is "enhanced" because it is higher bit precision (it is not altered or improved in any way). Note speed is from Stryd on indoor running, and from GNSS (GPS) in outdoor running. Do not use "enhanced altitude" field for calculating incline; it's from the Stryd pod's altimeter, not from the mapping software.
Note that for privacy reasons, GNSS location data are not available for the realworld cohorts. Processed elevation and turn rate data, however, are included, and GNSS data are included in the cohort2_course.csv file, as these runs took place on a standardized course at Indiana University.
Code for running the analyses is in /Code/ folder. Each script is independent, you can run them in any order. Main results are from univariate_analysis.R and depth_analysis.R. Results are exported to appropriately named folders.
Do be aware that the depth analysis can take >30 hours to run, even on a fast CPU, if you run it with the default rw_thin_pct (thinning percentage) of 0.25. Dial it back to 0.01 for testing or for an approximate reproduction of results.
For the MATLAB code that adds incline and turn rate, see /turn and incline calcs/ which includes a demo GPX file.
