| Summary: | 碩士 === 臺北巿立體育學院 === 運動器材研究所 === 99 === Purpose: To investigate the effect of walking and running on arch index, arch stiffness and plantar pressure of foot. Methods: Twenty-three non-athletic males with normal foot arch participated in this study. They need to walk and run 10,000 steps in two sessions with barefoot on treadmill with at least 5 days between the sessions. Prior to and after walking or running test, each participant’s arch index, arch stiffness and plantar pressure of right feet were taken. Paired t-tests were used to compare the differences between pre and post walking and running test and between post-walking and post-running test. Results: The arch index was increased after walking and running. The comparison between two post-interventions indicated that the arch indices of post-running intervention were significant higher than those of post-walking intervention. The arch stiffness was no significant difference after walking or running. The maximal peak pressure showed significant decreased on hallux, metatarsal and heel area in walking. Significant decreased on hallux and metatarsal but increased on midfoot area in running. Conclusions: Arch index increased after exercise. Running with higher impact was motivated to more collapsed range of arch. It will change plantar pressure distribution after exercise. But no significant change on foot arch stiffness.
