碩士 === 國立體育學院 === 運動科學研究所 === 93 === People take 8,000 steps every day.It bears plantar pressure for triple to fivefold of bodyweigh every step while walking and running.The Arch of foot and the angle of calcaneus in-eversion correlate with plantar pressure and gait.We recruit 39 College females (FF,19, 158.9±4.3Cm, 57.4±6.7Kg, Age, 21.2±5.3, AI, 0.36±0.03; NF, 20,159.5±4.3 Cm, 53.9±6.1Kg, Age,23.6±6.2, AI, 0.25±0.02).The angle of rearfoot motion(ARFM) and time percentage of gait(TPG) in walking and running(1.33m/s, 2.66m/s) were measured by EMED-pedar system and VICON-V624 motion analysis system.Two-way ANOVA repeated measure(α＝.05) and Pearson product moment correlation(P<.05) were applied. The results indicated that: (1)The female with FF’s plantar pressure on internal, external midfoot area and metatarsal region was several times than walking while running. The impulse (FTI ) and accumulating pressure load (PTI ) was several times (P<.05). (2) NF and FF’s ARFM maximum appeared on early swingphase in walking or running(P<.05). (3) There is no difference significantly between FF and NF’s TPG while walking and running, but there were difference significantly between walking and running. (4) FF’s TPG were correlation significantly on both phase between MF, PTI and FTI while walking. Except PP, plantar pressure were correlation significantly between TPG. There were no correlation significantly between MF, MMP and ARFM; TPG and ARFM,either. We suggested that steadied your rearfoot while moving high speed in order to reduce the plantar pressure.
