The instrumented stud
The solution allowing you to assess fatigue and biomechanics of the lower limbs in order to limit the risk of injury
A unique technology in the world
Measuring ground reaction forces
Up to 1kHz
Field analysis
Fully portable technology
Integrated force sensors
Directly in the studs, without modification of the shoe
Innovative solution
Patented technology
How do we detect fatigue?
At each step, more than 25 indicators are calculated and allow us to characterize the player's state of fitness on the pitch, in real conditions.
This allows us to quantify how tired a player is when running in a straight line. This validated solution now makes it possible to complement existing training load management systems.
This tool is the result of more than 5 years of research and a thesis carried out over the last 3 years
Step 1
Step 1
Technology validation
Procedures
Comparison of stud signals to a force platform
Results
Excellent agreement between the results of the platform and those of the instrumented studs
Conclusion
It is possible to reliably measure GRFs on the football field with this tool
Step 2
Step 2
Fatigue detection in the field
Procedures
Compare GRF indicators/patterns between the beginning and end of a run at constant speed until exhaustion.
Results
Significant differences found in all subjects, also strong inter-player differences
Conclusion
Fatigue can be detected and quantified in the field using instrumented studs
Step 3
Step 3
Quantification of fatigue in a professional audience
Procedures
Creation of a simple straight line running protocol allowing the collection of GRF indicators/pattern between before and after training
Results
Comparison of pre- and post-workout indicators makes it possible to obtain a musculoskeletal fatigue index
Conclusion
The fatigue index provides additional information to existing solutions and is better correlated with the appearance of injuries
