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.
The purpose of this study was to determine if pressure data, collected after taking one step or two steps, were similar to values obtained by using the traditional midgait method. Ten healthy subjects, with a mean age of 27 years, walked across a sensor platform sampling at 70 Hz. Each subject was randomly assigned to take one step, two steps, or multiple steps (midgait method) across the sensor platform. The results of the study indicate that the two-step method, in comparison with the one-step method, provides pressure data more representative of the midgait method, and different values for pressure and force will be obtained, depending on the method of pressure data collection selected by the clinician.
