Objective: The purpose of this study was to investigate the changes in foot morphology and foot motion using a multi-segment foot model, and ground reaction forces during prolonged walking in healthy middle-aged females.
Background: As people have experienced improved cardiovascular and muscularskeletal health, the popularity of prolonged walking has increased. However, only a few studies have suggested that prolonged walking may increase the risk of lower extremity joint injuries due to abnormal loading and decreased stability after muscle fatigue.
Method: Forty-two healthy middle-aged females (mean age: 45.4 ± 2.3 years, mean height: 160.7 ± 4.8cm, mean weight: 59.2 ± 6.9kg, mean foot size: 23.3 ± 0.7cm) participated in the study. The participants went through measurements of foot morphology and Q- angle before and after 40 minutes" walking. The participants were asked to walk at a speed of 1.1m/sec for 40 minutes. Foot motion and ground reaction forces were collected at three time intervals (0, 20 and 40 minutes). Changes in variables were compared at an alpha level of .05 using a paired t-test and repeated ANOVA, respectively.
Results: Arch index was decreased and Q angle was increased after 40 minutes" walking (p < 0.05). Increased toe out angle and attack angle of the foot at initial contact were observed as walking time progressed (p < 0.05). Increased flexion angles of multi-segment foot were found with increased walking time (p < 0.05). Finally, the participants experience greater braking force after 40 minutes" walking compared with 0 minutes and after 20 minutes (p < 0.05).
Conclusion: The participants experience kinematic and kinetic changes of the foot during a prolonged period of walking.
Application: The current findings suggest important biomechanical considerations when applying a walking intervention in a clinical trial to improve fitness or in developing adequate walking shoes.
