Background and objective: Vestibular evoked muscle potential (VEMP) is one of the new tools for evaluating atrial function, although few researches have been done on the effect of the indoor rock climbing workout (IRCW) on VEMP and on the balance of sighted and blind patients. Therefore, the purpose of this study was to compare the effect of eight weeks of wall workout on the latency of atrial excitatory muscle potentials, balance, body composition, and functional indices in the sighted and blind girls. Materials and Methods: In this quasi-experimental study, 20 students aged 7-12 years old were selected through available and targeted sampling. The subjects randomly divided into two groups: (1) Sighted Climbing Training (n=10) and (2) Blind Climbing Training (n = 10). The rock climbing program included eight weeks, three sessions per week, and each session for 30 to 45 minutes. Inferential statistics (variance analysis with repeated measures) were used for comparing intra and inter-groups means. The results were tested at the significance level of p <0.05. Findings: It was shown that the latency of excited muscular potential wave peaks in both blind and sighted groups did not change significantly. Dynamic balance, static balance, right hand strength, leg strength has increased significantly in both groups. The percentage of body fat has significantly decreased in both groups. There were no significant differences between the two experimental groups in the changes in the inter-group means in the latent variables of the excited muscular potential peaks of dynamic balance, static balance, right hand strength, left hand strength, leg strength and body fat percentage. Conclusion: Eight weeks of rock climbing training led to a decrease in body fat percentage and a significant increase in dynamic balance, static balance, and right hand strength, leg strength in sighted and blind children. Probably rock climbing practice can be used as a proper workout protocol for maintaining health and increasing the balance and physical strength of these individuals.
