Fatigue due to running has been shown to contribute to changes in plantar pressure distribution. However, little is known about changes in foot posture after running. We sought to compare the Foot Posture Index before and after moderate exercise and to relate any changes to plantar pressure patterns.
A baropodometric evaluation was made, using the FootScan platform (RSscan International, Olen, Belgium), of 30 men who were regular runners and their foot posture was examined using the Foot Posture Index before and after a 60-min continuous run at a moderate pace (3.3 m/sec).
Foot posture showed a tendency toward pronation after the 60-min run, gaining 2 points in the Foot Posture Index. The total support and medial heel contact areas increased, as did pressures under the second metatarsal head and medial heel.
Continuous running at a moderate speed (3.3 m/sec) induced changes in heel strike related to enhanced pronation posture, indicative of greater stress on that zone after physical activity. This observation may help us understand the functioning of the foot, prevent injuries, and design effective plantar orthoses in sport. (J Am Podiatr Med Assoc 103(2): 121–125, 2013)
