“…To assess the impact of long-distance running on foot structure, this study meticulously measured the dorsal and navicular heights, along with the overall foot length of each participant, both before and after the running trials. These measurements allowed for a detailed comparison to discern the morphological alterations in the foot induced by the running activity, providing crucial insights into the biomechanical adaptations associated with prolonged running exertion [15][16][17].…”

This study investigates the biomechanical adaptations of the longitudinal arch (LA) in long-distance runners, focusing on changes in stiffness, angle, and moment during a 60-minute run. Twenty runners participated in this experiment, and were asked to run at a speed of 2.7 m·s-1 for 60 minutes. The kinematic and kinetic data collected at five-minute intervals during running were calculated, including the stiffness of LA in the loading phase (k load ) and the stiffness of LA in the unloading phase (k unload ), the maximum LA moment (M max ), the range of LA angle change (∆θ range ), and the maximum LA angle change (∆θ max ). Foot morphology was also scanned before and after running. Variations of kinematic and kinetic data were analyzed throughout the running activity, as well as variations of foot morphology pre- and post-run. Results showed that there was a significant decrease in k load (p<0.001), coupled with increases in ∆θ range (p=0.002) and ∆θ max (p<0.001), during the first 15 minutes of running, which was followed by a period of mechanical stability. No differences were found in k unload and M max throughout the running process and the foot morphology remained unchanged after running. These results highlight a critical adaptation phase that may be pivotal for improving running economy and performance.

“…The influence of marathon events [15][16][17] and long-distance running [18,19] on foot biomechanics, particularly the LA, is a focal point in current research. Studies have explored the LA's response pre-and post-running, revealing mixed findings on its immediate effects.…”
