Summary

Ultra-long distance running up to 500 km initially reduces flat feet due to increased muscle tone. However, exceeding this distance in ultra-marathons leads to foot expansion, indicating a physiological limit.

Area of Science:

  • Sports Medicine
  • Human Physiology
  • Biomechanics

Context:

  • Ultra-long distance running presents unique physiological challenges.
  • Understanding the impact of extreme endurance events on the human foot is crucial.

Purpose:

  • To investigate the effects of prolonged running on foot morphology and biomechanics.
  • To identify potential physiological limits in ultra-marathon runners.

Summary:

  • 55 out of 110 starters completed a 1000-km ultra-marathon, running 50 km daily for 20 days.
  • Running 500 km initially diminished flat feet, possibly due to increased muscular tonus.
  • Foot dimensions increased after 500 km, suggesting a physiological limit is reached.

Impact:
