This study aimed to determine the relationship between bone mineral values and anaerobic power in professional wrestlers. A cross-sectional study was performed on 14 male wrestlers (22.9 ± 3.4 years) and 11 untrained men (24.5 ± 1.6 years; controls). Bone Mineral Content (BMC), Bone Mineral Density (BMD) and body composition were examined using dual-energy X-ray absorptiometry. Peak Power (PP) and Mean Power (MP) were measured by Wingate Anaerobic Test. The research showed that the wrestlers had greater leg lean mass, BMC and BMD, as well as MP expressed in absolute terms (W), and relative to body mass (W•kg^-1) compared with controls. MP (W) was correlated with leg lean mass in both groups. PP (W) and MP (W) were notably associated with BMC and BMD in both wrestlers and untrained men (r=0.608, p<0.021 and r=0.717, p<0.004) respectively, although less significant in controls. PP (W•kg^-1) and MP (W•kg^-1) were associated with BMD in wrestlers (r=0.616, p<0.05; r=0.641, p<0.05, respectively), but not in controls. In the total subject population, PP (W) and MP (W) correlated with leg lean mass, BMC and BMD. In conclusion, bone mineral values, especially BMD were significantly associated with anaerobic power in both the absolute and relative measures in wrestlers.
