Therefore, it can be concluded that conducting more studies on this area is required‬- ص‍‮‭Introduction: One of the most important factors and essential elements of physical fitness is keeping balance while performing different exercises, so that any balance disorder may lead to absence of ones control over his/her balance of center of gravity. Thus, decreasing in exercise performance would be inevitable. Regarding to the fact that in comparison to gymnastic, the effect of horseback riding on balance of static and dynamic is unclear and also due to the lack of comprehensive study in this field, the present research attempted to compare static and dynamic balance of male adolescent gymnasts and horse-riders. Methodology: The research was conducted according to a causal - comparative design in which two groups of ten male gymnasts and ten male horse-riders were chosen randomly with the range of age ۱۴-۱۷ years and body mass index ۲۱-۲۴ kg/m۲. Each group is at least with three years of semi-professional training history who participated voluntarily in this study. Static and dynamic balance were measured by Biodex Balance System SD with open and closed eyes in the case of fluctuation of overall stability index, Anterior/posterior and Medial/lateral stability index. All data was expressed as meanSD and analyzed using repeated-measures analysis of variance at <۰.۰۵ Results: The fluctuation of stability index which include overall, Anterior/Posterior and Medial/Lateral stability index of static and dynamic balance were different between gymnasts and horse- riders <۰.۰۵. So that in both groups, fluctuation with eyes closed were more in comparison to fluctuation with eyes open <۰.۰۵. However, the most fluctuation were related to dynamic balance with eyes closed. It was observed that fluctuation of dynamic balance of horse- riders were significantly more than gymnasts.In other words dynamic balance of male adolescent horse riders was less than gymnasts <۰.۰۵. Whiles the static balance of male adolescent gymnast was less than horse riders >۰.۰۵. Conclusion: According to the presented results, it could be concluded that the effects of horse-riding on static and dynamic balance are different from gymnastic. Moreover, the most fluctuation were observed on dynamic balance with eyes closed. In other words, the eyes condition (open or closed) may be considered as an important and intervened factor in the case of various effects of gymnastic and horse- riding on balance. However, static balance of horse‬
