Abstract: This paper explored the distribution pattern of plantar pressure in healthy young people of Tibetan and Han nationality in the plateau and compared the differences in the plantar pressure characteristics between the two nationality groups, which provides basic data for constructing a gait database for plateau populations. Using the Italian MPS plantar pressure testing system, plantar pressure tests were conducted on 160 selected healthy young people residing and migrating to high altitude in Tibet University, and the obtained data were statistically analyzed. The results are as follow: (1) there are differences in male contact area, female peak pressure, average pressure, and arch index between nationality groups when standing (P<0.05), and there are differences in female contact area and foot axis angle between nationality groups during walking (P<0.05). (2) There are differences in male contact area (Toe1,Toe2-5, Meta5), peak force (T1, T2-5, Meta2), peak pressure (Mid Foot) and impulse (T1,T2-5, Meta1, M2, Meta3, Meta4, M5) among nationality groups (P<0.05), and there are differences in female contact area (T1, T2-5, M4, M5, Medial Heel, Lateral Heel), peak force (T1, T2-5, M2), peak pressure (T1, M1, M4), average pressure (T1, T2-5, M4) and impulse (T1, T2-5, M1, M2, M5, MH) among nationality groups (P<0.05). (3) Arch index, peak force (T1, T2-5, M2), and impulse (T1, T2-5, M1, M2, M4, M5) are significantly correlated with nationality. There is significant difference in plantar pressure test indicators between Tibetan and Han nationality, and the distribution pattern of plantar parameters varies among different regions. The unique characteristics were found in the plantar pressure distribution of healthy young people from two nationality groups.
