Archer’s stance and gravity distribution is an important element to keep body balance; a proper planter pressure can supply archers to bring forth the efficient support. This research recruited 14 players for plantar pressure analysis (height:173.3±10.1 ㎝, weig w:77.2±24.5 ㎏,age 21.7±1.5 yr, archery participation 7.3±1.3 yr). This research divided archer’s plantar pressure into three areas, proleg area, an arch area, and heel area through EMED- PEDAR plantar pressure insole system to collect data, and analysis by t-tese and one-way ANOVA (p< 0.05), discussed the differences between open stance and close stance. The results were as follows: the majority of average plantar pressure of left foot is on arch area, the majority of average plantar pressure of right foot is on heel area, the majority of plantar pressure area of left and right foot is proleg area, the majority of average plantar force on left foot is proleg area, the majority of average plantar force on right foot is heel area. Therefore, when the player stand, average plantar pressure, plantar pressure area, and average plantar force are equally distributed between two feet’s three-area. The open stance had wider feet than the shoulder, right foot stands half the sole of foot more than the left, there fore, the stability is higher when shooting. The close stance had feet as wide as the shoulder or smaller, the sole’s basis area is smaller. It is easily affected by other factors such as wind. This will causes the body to lean back and forth. Archers’ arm will not have the same amount power produced; this will indirectly influence the archer’s performance.
