Common parkour vault techniques, landing styles, and their effects on landing forces
22 November 2021
This project was my final year dissertation for my Sport Therapy BSc undergraduate degree, the abstract of which was accepted at the BASES Conference 2021 and presented as a poster where it won the Human Kinetics Student Poster Presentation Award. This abstract was then also published in a special edition of the Journal of Sports Sciences.
My thanks to the sports department at London Metropolitan University, and in particular, my project supervisor Karl Grainger.

It’s important to know that this has not been extensively peer reviewed beyond the abstract for the BASES Conference. I’m proud of my work and I think my findings are, at the very least, interesting. But, please bear that in mind as you read it.
You can download the full force platform data I collected if you would like to perform your analysis. If you do so, please get in touch and let me know what you use it for and what you find, I’d be delighted.
Once downloaded, you’ll find the ‘data’ folder contains all the data in a variety of formats, including the raw force curves for all participants in both .txt and .dat formats. The .dat files are the force profile files saved by Bioware software directly, while the .txt files are the exported equivalent, containing some metadata at the top of the file.
The cleaned and compiled data can also be found in Rdata, Excel, CSV and SPSS formats. Some formats also include the data in long or wide layouts, as preferred. Most variables in each format should be self explanatory, with the most important being the distinction between the force values being in Newtons (result_n) or in multiples of participant bodyweight (result_bw).
Please be aware: The compiled datasets (in the ‘processed’ folder and usually anything with ‘pkvs’ in the filename) for R/Excel/CSV/SPSS etc have been through a cleaning script, the one I used to perform the analyses used in the final paper. Mainly this affects the Precision Landing style figures, as these are halved to approximate the force through a single limb, in order to match the Running Landing style figures. The raw data (.txt and .dat files) contains the original unhalved figures for Precision Landings, if desired.
Why are there so many file versions of the processed data, James?
Because I taught myself R to analyse this project, and went through a phase of experimenting with how it interacts with different file formats. Since I had them, I thought I might as well put them out there. They’re all the same underlying data; just pick whichever you prefer, or work from the raw files to start from scratch.
