Abstract

The purpose of this study was to determine the change, if any, in foot volume over time after exercise, specifically a long-distance 5 Km run. Five UNLV Women’s Track & Field and Cross- Country distance athletes (n = 5; 20 ± 1.87 years; 54.50 ± 3.71 kg; 160.88 ± 4.98 cm) were recruited to participate in this study. The dependent variables were foot volume and foot size. These variables were measured pre and post a 5 Km run at a self-selected somewhat hard pace over the independent variable time. Foot volumetrics were performed five times, (Pre-run, post- run(5 min), post-run(10 min), post-run(15 min), post-run(20 min)) using a Foot Lucite Volumeter. Similarly, actual foot size was measured five times (Pre-run, post-run(5 min), post-run(10 min), post- run(15 min), post-run(20 min)) using a Brannock Device . Two repeated measures ANOVA were run using SPSS statistical package for Windows version Fix Pack 1 and an omnibus F-ratio was calculated to determine significance. Foot volume was influenced by the main effect of time (p < 0.05). Using Simple-effect post-hoc tests, it was determined that foot volume at pre-run was not different to post-run(5 min) nor post-run(20 min) (p > 0.05). However, foot volume at pre-run was different from post-run(10 min) and post-run(15 min) (p < 0.05). Foot size was not influenced by the main effect of time (p > 0.05). A Pearson product moment correlation (r) was used to assess the relationship between pre-run foot size and pre-run foot volume. A moderate positive correlation between pre-run foot size and pre-run foot volume (r(5) = 0.42) was observed. However, the moderate positive correlation between pre-run foot size and pre-run foot volume was not statistically significant,(p < 0.05). The results from this study highlighted the importance of determining the moment in time that the foot volume is measured post a 5 km run as a way to understand the influence of exercise on foot volume. However, additional research is needed to fully understand the exact mechanism causing the change in foot volume.
