The objective of this study was to determine the effects of a postural control exercise program on static balance and accuracy of archery throwing in infant (12-14 years old) and cadet (15-17 years old) categories. A total of 12 athletes per each category took part in the study. As measurement tests, we used the Standing Stork Test (open / closed eyes) for balance and the assertiveness in target launch precision test (6 rounds) before and after the exercise intervention. This consisted of a bi / unipedal balance training program lasting 8 weeks. The results showed a significant increase in unipedal equilibrium with open eyes in the infant group and for both legs; however, no changes were detected in the closed-eye modality. The cadet category showed significant differences in the unipedal equilibrium test with open eyes only for the dominant leg (right); no changes were found for the left leg, nor in the closed-eye modality. The assertiveness test of the archery only improved in the infant group, whereas in cadets it did not change at post-test. It is possible that static postural balance training optimized patterns of postural and visuomotor control at early ages (under 15 years old) compared to the group of cadets, and therefore the throwing accuracy was enhanced. It is recommended to endorse these exercises at early ages so to empower the skills needed in the sport of archery.
