How does the slope gradient affect spatiotemporal parameters during running? Influence of athletic level and vertical and leg stiffness

The current evidence leaves certain questions unanswered, including whether well-trained athletes adapt to different slope gradients in the same way as amateurs, and whether stiffness influences spatiotemporal adaptations during uphill running. This study aimed to determine the effect of different slope gradients (0%–11%) on spatiotemporal gait characteristics during running, taking into account the influence of athletic level, vertical and leg...
