The purpose of this study was to characterize the spatiotemporal, force, and subjective effects that occur during an extensive run in novice female runners. Foot sole pressure, rate of fatigue, and speed were recorded during a 45-min flat ecological run. No significant effects were found in spatiotemporal, force-time, or rate of fatigue responses outside of the initiation phase of the running bout. When participants were grouped according to their pacing strategy, those with a decreasing speed over time exhibited significant decreases in rate of force development as time progressed. Participants tended to decrease mechanical loading variables, and increase their rate of fatigue throughout the run. Future studies should investigate a larger number of subjects to determine if these tendencies are characteristic of novice female runners.
