Épisode 1/3
Paralympics: how to optimise jumping blades for long-jumper amputees
On January 3rd, 2023
4 min reading time
Fabien Szmytka
Researcher at ENSTA Paris (IP Paris)
Jean-François Semblat
Head of mechanics and energy department at ENSTA Paris (IP Paris)
Élodie Doyen
PhD student at ENSTA Paris (IP Paris)
Key takeaways
In the context of the 2024 Olympic and Paralympic Games, studies are being conducted to improve the performance of tibial prostheses.
The Paralympic athletes concerned use spring-like jumping blades to replace the amputated limb.
The main challenge is to convert the athlete's kinetic energy into “momentum”, in order to jump as far as possible.
In addition to improving performance, the aim is also to improve the comfort of athletes by avoiding skin-prosthesis friction as much as possible.
The study of static and dynamic forces is put to use for the benefit of the human being, in order to advance the “augmented human”.
Épisode 2/3
How to help swimmers win their races
On January 3rd, 2023
5 min reading time
Rémi Carmigniani
Researcher at École des Ponts ParisTech at Laboratoire d'Hydraulique Saint-Venant
Key takeaways
Rémi Carmigniani and his team are studying the physics of swimming and the speed-cadence relationship of swimmers.
The objective: to understand the evolution of speed as a function of cadence and to relate it to the power delivered to the arms to move forward.
Accelerometers, force sensors and cameras are used to follow the swimmers underwater.
One of the main topics is the study of the swimmer’s start, and optimisation of the trajectory.
The ultimate goal is to help swimmers optimise their trajectory in the first 15 metres at the start and at the turns.
Épisode 3/3
Using virtual reality to boost skills in Olympic boxers

Franck Multon
Professor at Université de Rennes2 at Institut de Recherche en Informatique et Systèmes Aléatoires (IRISA)
Key takeaways
The REVEA project aims to use virtual reality (VR) for sports training.
With the 2024 Olympics fast approaching, this project will help athletes improve certain “sub-skills” such as speed and motor coordination.
To overcome the limitations of a real training session, a VR simulator has been developed based on measurements of athletes' movements in 3D.
The project is part of a more general sports programme in which physical, mental, and technical preparation complement the VR sessions.
The system is constantly being improved through feedback from coaches and athletes, but also by applying new AI research.
