    (Elsevier, 2023) Kurtoglu, Erdal; Payas, Ahmet; Duz, Serkan; Arik, Mustafa; Ucar, Ilyas; Tokmak, Turgut Tursem; Erbay, Mehmet Fatih
    Objective: Taekwondo, which is the most preferred sport among the martial arts, is known to improve individuals physically, spiritually and mentally. The aim of this study is to reveal the effect of teakwondo sport on the brain and brain structures.Design;: 30 taekwondo athletes and 15 control groups were included in this study. Diffusion tensor MR images of each participant were taken. The information was obtained by the self-declaration of the athletes, whether they were sports years, amateur or elite.Method: Total brain volume and volumes of white matter, gray matter, frontal lobe, precentral gyrus, cortico-spinal tract, basal nuclei, postcentral gyrus, hippocampus and amigdala and the ratio of these volumes to total brain volume were evaluated statistically between the groups using MriCloud software and ROIEditor program.Results: An increase in total brain volume, gray matter, frontal lobe and precentral gyrus volume in athletes was associated with taekwondo training. When the ratio of brain parts to total brain volume was examined, it was determined that there was a difference in the ratio of gray matter, white matter volumes in amateur athletes, right frontal lobe, left corticospinal tract, right postcentral gyrus volumes in elite athletes, and left postcentral gyrus volumes of both athletes compared to sedentary individuals.Conclusions: The increase in the volume of gray matter, frontal lobe, postcentral gyrus and corticospinal tract together with the brain volume shows that taekwondo exercise contributes to physical, spiritual and mental development.

    The Effect of Ultramarathon Running on Bone Mineral Density in Male Athletes
    (Int Journal Applied Exercise Physiology, 2020) Duz, Serkan; Arik, Mustafa
    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.
