Variations in foot volume before and after exercise.

Foot volume measurements were taken on 12 feet of nine female intercollegiate volleyball players (mean age of 20 years) before and after a 2-hr rigorous practice session. No significant difference was found between foot volume before and after exercise. A slight reduction in the foot volume after exercise was noted in comparison with the foot volume before exercise. These findings suggest that fitting footwear with extra space in front of the longest toe to accommodate changes in foot length associated with foot volume increases following exercise is not necessary. However, providing extra space in front of the longest toe during shoe fitting should still be considered in order to accommodate anterior sliding of the foot during athletic activities.
