The purpose of this research was to compare the balance ability between canoe polo players and untrained college students by using forces plates. Eight male canoe polo players and eight untrained college students were served as the subjects for this study. The mean height, weight and age of canoe polo players were 174 ± 6.61 cm, 68.88 ± 9.43 kg and 18.9 ± 1.5 years. The mean height, weight and age of untrained college students were 174 ± 3.11 cm, 66.13 ± 3.91 kg and 19.3 ± 1.3 years. The method of this study was right leg stance with eyes-closed test and subjects should changed right leg to left leg after previous test about 5 minutes later. There were some parameters were compared between two groups, including the sums of every single leg displacement, the range of anterior-posterior swing, the range of medial-lateral swing, swinging area, and the swinging area and the length of center of pressure swinging track during per five seconds. Carry on starting capture data while subject stood on force plate by single leg stability and capturing data for 20 seconds. COP data was captured by using kistler force plate（100Hz） and the selected variables were tested by t-test of independence between groups（α＝.05）and pair t-test of dependence within factors（α＝.05）. The main results of this study were as follow: the balance ability between canoe polo players and untrained college students was much the same（p＞.05）. The result shows that the canoe polo players balance ability was the same with untrained college students at one leg stance with eyes-closed test. According to this research the authors would suggest the need for future research focusing on searching certain method to increase core muscles ability or to increase balance ability on up-body in order to further discuss the canoe polo players’ balance ability.
