碩士 === 國立體育學院 === 運動科學研究所 === 94 === Abstract The flat foot lacks the shockproof and balanced function, the main reason is that the arch of foot of sport course is apt to collapse. And in the evolution of the foot, the bone of the foot probably wants until 18 years old while developing riply. This research by 20 flat foot male(172.65±4.35cm，75.05±17.02kg，22.05±2.63years，AI=0.34±0.03) and 20 normal foot male(175.65±7.36cm，68.95±9.96kg，22.15±2.90years，AI=0.25±0.02). And use EMED-PADER insole pressure measuring system, and VICON motion capture system in step to collect dynamics and kinematics data. We calculate rear foot motion by Euler angle, and the insole pressure parameter of every fen area to discussion. With independent sample t-test(P＜.05), sample in pairs t-test(P＜.05), and Pearson product moment correlation(P＜.05) to statistic. The following of the result:(1) Flat foot (MF) and (PP) will with increase of the speed increase, and (PTI) and (FTI) will increase with the time of foot and ground touch.(2) The flat foot’s rear foot movement will increase with the speed increase.(3) While walking and running, the flat foot’s (MF) and (FTI) will get great loading in inboard of foot and outboard of foot, and the flat foot’s (PP) and (PTI) will to skew outside of the foot.(4) The rear foot angle when static standing, the maximum of eversion angle, and the value of eversion of the rear foot are greater then normal foot, and that will increase with speed increase. (5) The area got correlation significantly between insole pressure parameter and rear foot angle will increase, when increase in speed.
