The purpose of this study was to compare bone mineral density of older aged ultramarathon runners with physically active and sedentary age-matched males. Forty-two healthy males aged between 44 and 56 years participated voluntarily to the study and were grouped equally as ultramarathon (UM), active males (AM) and sedentary control (C). BMD was measured at the lumbar spine (L2-L4) hip, femoral neck and total body by DXA. Statistical analysis was performed with IBM statistics (SPSS version 23.0, Armonk, NY, USA) windows package program. Kruskal-Wallis H test was used to compare differences between groups which was not normally distributed. Dunn's post-hoc test was performed to determine which groups were different from others. The results were evaluated within the 95% confidence interval and significance was set at p<.05. The results showed that femoral neck (p=.024), hip (p=.001), lumbar spine (p=.000) and total BMD (p=.000) of the UM runners were significantly lower compared to AM group. Moreover, total BMD of the UM runners were significantly lower than those of the C group (p=.001). On the other hand, femoral neck (p=.043) and lumbar spine (p=.028) BMD of the AM group was significantly higher compared to C group. As a conclusion, it is thought that middle-aged male UM runners should include weight-bearing exercises in their training program to attenuate the decrease in BMD because of increased exercise volume.
