The purpose of this study was to analyse the postural balance and characteristics of the balance adaption. The data of postural balances are collected by KAT2000. The participants are 40 persons healthy individuals 20 males, 20 females who have no orthopedic and neurological impairments, aged from 19 to 25 years(mean ages is 21.5). Prior to participation, each subject informed the procedures of experiment from researcher. In order to determine the statistical significance of results, the on way ANOVA was applied at the 0.05 level of significance. The results were as follows : 1. The ability of balance performance showed decreasing trend according to increase the both leg discrepancies(p <0.05). 2. The ability of balance adaption showed increasing trend according to time passed(p ‹0.05). 3. There is no significant difference between male and female in the parts of balance adaption(p> 0.05). 4. There is no significant difference between heavy and light weight in the parts of balance adaption(p> 0.05).
