ÖZETBu tez çalışmasının amacı, manyetik rezonans (MR) görüntüleme ile beyinde yapısal ve fonksiyonel farklılıkları gözlemleyerek, karate sporunun gerektirdiği antrenmanların sonucunda oluşan nöral değişikliklerin ortaya konulmasıdır.ABSTRACTThe aim of this study is to reveal the neural changes that arise as a result of the training required by karate sports by observing the structural and functional differences magnetic resonance imaging (MRI) of the brain.

This study aimed to examine the effects of using a mouth guard in Karate on respiration parameters. The study sample consisted of 10 volunteer elite male karate athletes who participated in the National Karate Team and still practice the sport (24.4±6.3years, 176.2±7.4 cm, 71±4.1 kg). The athletes were exposed to respiration tests without and with mouth guard with 2 days interval that give FVC, FEV1, MVV and PEF values. In the light of the found parameters, were no meaningful differences were observed in measurements of parameters between the measurements with and without a mouth guard (p > 0.05). The athletes continued their routine training between pre-test and post-test. In conclusion it was seen that the use of mouth guard did not directly affect the breathing performance., Bu çalışmada Karate sporundaki ağız koruyucusu kullanımının solunum parametrelerine etkisini incelemek amaçlanmıştır. Çalışmaya Karate Milli Takımı’nda yer almış ve aktif spor yaşantısı devam eden gönüllü 10 erkek elit karate sporcusu (24,4±6,3yıl, 176,2±7,4 cm, 71±4,1 kg) dahil edilmiştir. Sporcular FVC, FEV1 MVV, PEF değerlerinin elde edildiği solunum testlerine 2 gün ara ile dişliksiz ve dişlikli olarak katılmıştır. Kaydedilen parametreler ışığında, dişlikli ve dişliksiz ölçümler arasında istatistiksel açıdan anlamlı bir ilişki gözlenmemiştir (p > 0.05). Sporcular ön test ve son test arası rutin antrenmanlarına devam etmiştir. Sonuç olarak, dişlik kullanımının solunum performansını direkt olarak etkilemediği görülmüştür.

18th National Biomedical Engineering Meeting (BIYOMUT) --OCT 16-17, 2014 -- Istanbul, TURKEY, WOS: 000381577500013, Duru, Dilek Göksel (Arel Author), Eye movements are essential for natural vision. Eye tracking technology is being used in research in many disciplines to examine the differences in the visual attention of experts and novices. Eye tracking research in sports focuses in the performance of athletes and its relation with perceptual processes. The aim of these studies relies in training the visual behavior of the athletes and to arrange trainings to increase their performance. In this study, the elite group is the Karate-Do players, and the aim is to extract their visual behavioral characteristics and patterns, to explore their gaze strategies, and the differences in their perception, attention and judgement. The experimental paradigm is a Kata and Bunkai video montage from World championships, where the elite athletes are asked to follow the techniques of the players, and the controls, which are interested in Karate-Do but not ever tried it, are asked to follow the movements of the players. During this time the eye tracking is done, and average fixation times, and dwell time in each area of interest have been calculated, and a significant difference between the two groups has been detected. The elite athletes have less fixation counts but longer fixation time compared to controls. So the professionals are not only extracting information from the center, but also from the peripheral areas. This finding is in agreement with the eye tracking literature. Future works will rely in investigating Karate-Do players from varying Karate-Do branches in groupwise comparison.
