Tools for sport and exercise physiology
MARCWILLS stands for Mount ARGa WILLiS. Arga is an old word for mountain, and Willis is the mountain that stands over the town where I was born. It is not one of the famous peaks: fewer people climb it, and its forests stay green and quiet. Yet from its slopes, clean water rises and runs all year round into the rivers that feed the land below. The mountain does not draw crowds, but it gives life to the valley anyway. I named this work after it because I want these tools to be like that mountain. Like its springs, they start at the source: every heartbeat recorded carefully, nothing hidden, and the data clear enough to see through, flowing on to wherever research needs it.
Tools for sport and exercise physiology
MARCWILLS is a family of tools I am building for sport and exercise physiology: for researchers, lecturers, and students who need to measure the human body carefully, outside a hospital and often outside a fixed laboratory.
It began with one question: how do you record clean heart rate variability data in a lab room, on a treadmill, in an open field, or at the pool, without losing track of what really happened during the recording? The answer became HRVA. Everything else in the family grows from the same engine and the same principles.
HRVA is a smartphone app that records heart rate variability live from a Polar H10 chest strap: every heartbeat, real-time HRV, markers and analysis segments, participant management, and an honest record of data quality. Each session can be exported as a PDF, CSV, rr.txt for Kubios HRV, or a single encrypted .hrva file.
HRVA Workbench is a desktop app built to open the .hrva files that HRVA exports and turn a folder of sessions into an organised analysis: timelines of the whole recording, marked segments, and comparisons between participants and study conditions. You decide which data goes into the analysis and leave the rest aside without deleting it.

A Polar H10 sends every heartbeat to HRVA. HRVA records the session and exports it as one encrypted .hrva file. HRVA Workbench reads that file on a computer for analysis. The recording travels from the lab to the analysis complete, together with its markers, segments, and data-quality record.
Researchers running HRV studies in the lab, on the treadmill or bike, in the field, or at the poolside.
Lecturers and students in exercise physiology who want to see the heart and the autonomic nervous system respond live.
Sport scientists who need clean, traceable data rather than a single score.
MARCWILLS tools are for sport-science research, teaching, and wellness monitoring. They are not medical devices and are not intended for diagnosis or medical decisions.
Researchers who use these tools are responsible, under their own research protocol, for obtaining informed consent separately from every participant and ethics approval where required.
