abstract = "Exercise has been shown to improve health in people with diabetes. However, various walking speeds and durations in daily life may increase plantar pressure, thereby increasing risk for diabetic foot ulcers. Plantar thickness and stiffness have been demonstrated to be associated with plantar pressure. The pads under the heel and metatarsal heads include microchambers and macrochambers for absorbing impact forces during weight-bearing activities. The objective of this study was to investigate the effect of different walking intensities on the changes of biomechanical properties of plantar soft tissues. The healthy participants were tested in a 3 × 2 factorial design, including three walking speeds (1.8, 2.7, and 3.6 mph) and two durations (10 and 20 min). B-mode ultrasound images were obtained at the first metatarsal head to quantify plantar soft tissue thickness and stiffness before and after walking. Our results showed that the walking duration factor causes a significant effect on the macrochambers thickness. In addition, the speed factor caused a downward trend of the macrochambers stiffness with a lower walking speed.",
