Balance ability is essential for top athletes to reach peak performance in sport competitions. Balance is also a very important factor for athlete talent identification since muscle can create adequate power and strength in dynamic balance during human movement. The goal of this study is to provide unique and novel insights into human postural control by determining both static balance and dynamic balance ability. The other goal is to investigate the difference of balance ability between archery players and non-athletes. The archery players group consisted of ten elite archery players with mean age 21.6±1.3 years and the second group consisted of ten non-athletes with a mean age of 20.4±0.5 years. The subjects were asked to kick a ball with a single leg twice before the commencement of the test. The leg selected to kick the ball was defined as the dominant leg, while the other leg was referred to as the supporting leg. The measurement equipment of this study were Kistler force platform, balance trainer and Breg K.A.T. 2000. The results of this study were summarized as followed: (1)the static standing steadiness of archery players group were significantly better than the non-athletes group, (2)the unstable static balance ability of archery players group was significantly better than the non-athletes group, (3)the unstable dynamic balance ability of archery players group was significantly better than the non-athletes group, Based on the findings of this study, it is suggested that regular sport training could significantly enhance balance ability.
