    The Relationship between Basal Ganglia Volume and Audiovisual Reaction Time in Turkish Elite Athletes
    Karabekir, S; Aksu, F; Gunay, E; Karabekir, NG
    Background: In this study involving young adult elite athletes and healthy sedentary individuals, volumetric analyses were performed on basal ganglia (BG) involved in the coordination of motor movements. Aims and Objectives: In a group of athletes with high coordination speed, potential relationship between BG volumes and audiovisual reaction time of acquired-trained hand movements was explored by examining whether these individuals had significant differences in terms of BG volumes. Materials and Methods: Nineteen elite athletes aged between 19 and 25 years (9 male and 10 female) and 20 sedentary subjects (10 male, 10 female) were included. Gender, age, height, weight, and body-mass index (BMI) were recorded. In each group, audiovisual reaction time and stereological basal ganglia volumes were assessed and statistically analyzed. Results: Elite athletes react more rapidly to auditory stimuli than visual stimuli. As compared to sedentary individuals, elite athletes exhibited significantly shorter visual reaction time and only numerically shorter (statistically insignificant) visual reaction time. Left BG volume was higher in both groups, compared to right side). Conclusion: Our data may contribute to the construction of a database of normal BG morphology and provide useful information for clinicians and athletes.

    IMPACT OF YOGA INTERVENTION ON PHYSICAL FITNESS PARAMETERS IN PREADOLESCENT CHILDREN: A RANDOMIZED CONTROLLED TRIAL
    Bagkur, M; Gunay, E; Yerlikaya, T; Oniz, A
    Purpose: This study aims to assess the impact of yoga on physical fitness among healthy primary school children using a randomized control design. Material and Methods: A total of 52 children, aged 8-13, were randomly assigned to either the Yoga Group (n = 27, mean age = 10.48 +/- 1.25 years) or the Control Group (n = 25, mean age = 11.20 +/- 1.50 years). The participants underwent evaluation using the EUROFIT Test Battery as the primary outcome measure The Yoga Group engaged in 45-minute yoga sessions twice a week for a duration of 10 weeks, while the Control Group received no intervention. Outcome assessments were repeated at the conclusion of the 10-week intervention period. Results: Significantly positive enhancements were observed in the Yoga Group across various components of the EUROFIT Test Battery, including balance, speed, flexibility, muscle endurance, and Conclusion: These findings demonstrate that yoga interventions contribute to improvements in physical fitness among preadolescent children. Consequently, incorporating yoga exercises into the school curriculum is recommended, given their efficacy, minimal resource requirements, and positive impact on sports readiness.

    CEREBRAL BLOOD FLOW AND METABOLISM DURING VERTICAL IMMERSION AND IN-WATER EXERCISE
    Turkmen, D; Guducu, C; Bediz, CS; Gunay, E
    Vertical head-out water immersion has different physiological effects on the human body system due to hydrostatic pressure and different water temperatures. This review examines the changes in cerebral blood flow and metabolism during head-out water immersion and in-water exercise. Systematic research was conducted in PubMed, ScienceDirect, Scopus databases, by binary research methods. It included 11 articles that met the inclusion criteria. Studies have shown that acutely vertical head-out immersion in thermoneutral water and in-water exercise positively affects the circulation and metabolism of the brain. In healthy people, vertical immersion in thermoneutral water increases brain activity by increasing cerebral artery velocity and oxygenation. But, acutely, immersion in hot and cold water does not have a positive effect on cerebral circulation.

    EVALUATION OF PHYSICAL ACTIVITY LEVELS, SLEEP QUALITY AND NUTRITIONAL HABITS OF PARAATHLETES DURING THE PANDEMIC PROCESS
    Bediz, C; Gunay, E
    Purpose: Cancellation or postponement of sports events due to the COVID-19 pandemic has caused great stress for athletes. There are limited studies on how physical activity levels, nutritional habits, and sleep quality are affected, especially in physically disabled athletes(para-athletes) during the pandemic process. The aim of the research is to examine the physical activity, nutritional habits, and sleep quality levels of para-athletes during the pandemic process. Material and Methods: Eighty-seven male para-athletes were included in the study. The personal data form required to determine the characteristics within the study subject International Physical Activity Questionnaire Short Form (IPAQ Short Form), the Pittsburg Sleep Quality Index Questionnaire were used in a way consistent with the study. In addition to these sections, changes in participants' nutritional habits were also questioned. Results: The total MET values of para-athletes were determined as 3233 +/- 1421. The sleep quality index total score averages of the participants were 5.83 +/- 0.80 points, indicating the level of poor sleep quality. Food consumption of the participants It was found that 56% of them increased their food consumption, 28% did not change, and 18% decreased. Conclusion: The results of the study showed that physical activity, nutrition, and sleep processes, which have an important place in the life cycle of para-athletes, were adversely affected during the pandemic process.

    Evaluation of Lentiform Nuclei Volume in Healthy Individuals Who Exercise Regularly Using the Semi-automatic Tracing Technique
    Aksul, F; Karabekir, S; Karabay, N; Gunay, E
    This study conducted volumetric analyses on the lentiform nuclei, specifically the putamen and globus pallidus, in healthy individuals. The analyses considered age, gender, and body mass index. The measurements were performed separately for each hemisphere. This study aimed to examine potential differences in regular exercising men and women based on age, gender, and body mass index (BMI) through volumetric analysis of lentiform nuclei. A total of 16 individuals (7 female and 9 male) who exercise regularly were randomly selected for this study. The cross-sections were assessed to determine the volumes of the left and right lentiform nuclei in relation to age, gender, and body mass index for each participant. Statistical analysis was performed using the semi-automatic tracking method in MRI. Both genders showed higher left lentiform nuclei volume and putamen volume, while the right globus pallidus volume was also higher. However, these differences were not statistically significant. The volume of the lentiform nuclei was found to be greater in women compared to men, although this difference was not statistically significant. A significant positive correlation was observed between the volume of the right globus pallidus and age in men. A positive correlation was observed between right putamen volume, left lentiform nuclei volume, and left putamen volume with body mass index in all subjects. However, this correlation was not statistically significant. The data may contribute to the creation of a comprehensive database that includes typical lentiform nuclei and potential asymmetrical alterations in brain morphology. Furthermore, it has the potential to offer valuable insights to clinicians and anatomists.
