Stryd biomechanical parameters as indicators of running economy and performance.

This study investigates the relationship between biomechanical metrics provided by the Stryd Power Meter foot pod and running economy (RE) and performance in 15 high-caliber male athletes. Key findings indicate that ground contact time (GCT) and form power (FP)—the vertical component of power related to the center of mass movement—are significant predictors of RE at running speeds of 10 and 12 km/h, as well as of performance during nine- and three-minute all-out treadmill efforts. Vertical oscillation (VO) also correlates with RE at 10 km/h, while running effectiveness (REF) and leg spring stiffness (LSS) showed no significant associations. These results suggest that GCT and FP, measurable via the Stryd Power Meter, can serve as practical indicators for monitoring and improving running economy and performance in trained male runners under controlled treadmill conditions.
