Summary
Foot volume in volleyball players did not significantly change after rigorous exercise. While not necessary for volume changes, extra toe space in footwear is recommended for anterior foot sliding during athletic activity.
Area of Science:
- Sports Medicine
- Biomechanics
- Podiatry
Background:
- Foot volume changes during exercise are a concern for athletic footwear fitting.
- Previous research suggests foot swelling after physical activity.
Purpose of the Study:
- To investigate the changes in foot volume in female intercollegiate volleyball players after a rigorous practice session.
- To determine if significant foot volume increase necessitates extra toe space in athletic footwear.
Main Methods:
- Foot volume was measured in 12 feet from nine female volleyball players (mean age 20 years).
- Measurements were taken before and immediately after a 2-hour rigorous practice session.
Main Results:
- No statistically significant difference was observed in foot volume before and after exercise.
- A slight, non-significant reduction in foot volume was noted post-exercise.
Conclusions:
- Increased foot volume after exercise is unlikely in this population, suggesting extra toe space solely for this purpose may not be required.
- Anterior foot sliding during athletic activities remains a factor to consider for optimal footwear fit, warranting some extra toe space.
