Oral presentation at ECSS 2025: A novel bioenergetic model of sprint running
We are proud to announce that Jérémy Briand presented our lab’s research at the 30th Annual Congress of the European College of Sport Science (ECSS) held in Rimini, Italy from July 1-4, 2025.
A Novel Bioenergetic Model of Sprint Running Performance
Jérémy delivered an oral presentation in the Statistics and Analyses I - Endurance Sports session (OP-AP42), presenting work developed in collaboration with Pietro Enrico di Prampero, Cristian Osgnach, Guy Thibault, and Jonathan Tremblay.
Key findings
The research proposes a comprehensive bioenergetic model that details the time course of aerobic, anaerobic lactic, and anaerobic alactic contributions across 100-400m sprint distances. Using velocity data from the 2009 World Athletics Championships, the model:
- Accurately predicted metabolic power trajectories (R² = 0.94-0.98) for all sprint distances
- Estimated anaerobic alactic capacities of 376 J/kg (men) and 259 J/kg (women)
- Found that anaerobic metabolism accounts for ~95%, 88%, and 70% of total energy in men’s 100, 200, and 400m events respectively
This work has since been published in the European Journal of Applied Physiology and is available on our publications page.
runrgetics package
The bioenergetic model presented at ECSS is implemented in our open-source R package runrgetics, available on GitHub.
Congratulations to Jérémy for this excellent presentation representing our lab on the international stage!
