Presentation at the GERS-P National Conference 2025
Our laboratory was represented at the 29th Journées Nationales du GERS-P (Exercise, Rehabilitation, Sport and Prevention Group) held in Rennes, France on September 11-12, 2025.
Cardiopulmonary Responses to High-Power Eccentric Cycling
Jonathan Tremblay presented Marc-Étienne Villeneuve’s research on cardiopulmonary responses to eccentric cycling, conducted in collaboration with Ruddy Richard (Université Clermont Auvergne).
Summary
This study explores cardiopulmonary responses to high-power eccentric cycling (~1000W) compared to isoenergetic concentric cycling. Nine participants who completed 16 eccentric training sessions performed incremental exercise tests in each modality.
Key findings:
- Maximal eccentric power was 4.2 times higher than concentric mode (756±110 vs. 181±50 W) at similar oxygen consumption
- Cardiac output and heart rate were significantly higher in eccentric mode
- Systolic and diastolic blood pressures were lower
- Systemic vascular resistance decreased significantly in eccentric mode
Implications for rehabilitation
These results highlight the potential of eccentric cycling as a training tool enabling high mechanical work at low metabolic cost, particularly for populations with reduced cardiovascular capacity. These data pave the way for intervention studies evaluating the effectiveness of high-intensity eccentric training in cardiovascular rehabilitation.
This work highlights the excellent research conducted by Marc-Étienne Villeneuve in our laboratory.
