    2020 SONRASI SPORDA YETENEK SEÇİMİNDE ULAŞILAN NOKTA VE TEMEL TARTIŞMALAR
    (Iğdır Üniversitesi, 2022) Erdem Subak, Gülhan; Müniroğlu, Recep Sürhat; Kaya, Kaan
    Tüm spor dallarında, elit sporcular ve olimpiyat seviyesinde sporcular yetiştirebilmenin en önemli basamaklarından biri yeteneğin keşfedilmesidir. Geçmişten günümüze yetenek seçimi ile ilgili çok sayıda araştırma yapılmıştır. Bu araştırmaların bir kısmı yetenek seçimini daha iyi ve isabetli şekilde yapabilmeyi sağlayacak model tasarımları üzerinde dururken, bir kısmı yeteneği belirleyen faktörleri, bir kısmı yeteneğin gelişimine yönelik basamakları ve diğer birçok konuyu tartışmaktadır. Uzun yıllardır incelenen ve geliştirilen yetenek seçimi modelleri üzerine yeni modeller de tasarlanmaya başlanmıştır. Bu derlemenin amacı 2020 yılı sonrasında yetenek seçimi üzerinde çalışılan güncel konuları bazı ana başlıklar altında sunmaktır. Bu derlemenin yetenek seçimi alanında araştırmalar yapan bilim insanlarına, antrenörlere, scoutlara, spor kulüplerine ve spor alanında çalışan tüm bireylere, alandaki en güncel durumu özetlemesi hedeflenmiştir.

    Association between body composition, physical activity level and Illinois agility test performance in young males and females
    (Iermakov S S, 2022) Subak, Erdem; Kaya, Kaan; Viga, Saban O.; Ocak, Muhammed H.; Ağaoğlu, Ceren; Bekiroglu, Asli
    Background and Study Aim Agility performance, which is a skill related to fast change of direction, explosiveness, and quickness, is a vital performance component for team sports. Illuminating factors that affect agility is substantial to understand the ability requirements and improve. This study aims to investigate correlations of the body analyze parameters and agility performance. Material and Methods One hundred twenty three young participants (93 male, 30 female) were included in this research. Height, weight, fat (%), fat (kg), fat-free mass (FFM), muscle mass, total body water (TBW, kg, and %), bone mass, basal metabolic rate (BMR), metabolic age, visceral rating, and body mass index (BMI) measured for all participants. Illinois Agility Test (IAT) was used to analyze agility performance. A questionnaire including questions about the physical activity level of participants was applied to all participants after IAT. Results Results showed that height was a dominant determinant of IAT performance. There were significant positive correlations between height (negative correlation in women), body weight, fat percentage, fat mass, and visceral rating level (p < 0.05). TBW (%) had a negative relation with IAT duration (p < 0.001). There was a statistically significant difference in terms of IAT between the participants who stated their physical activity levels as low, medium and high (p = 0.025*). Increased daily physical activity level and daily step count increased the agility performance (p < 0.05). Conclusions Coaches and athletes should be considered especially body weight, fat (%), hydration status, and daily physical activity level to improve agility performance.

    Comparative analysis of external load in small-sided games versus official matches among professional football players
    (Iermakov S S, 2024) Kaya, Kaan; Gurol, Baris; Tarakci, Selcuk
    Background and Study Aim. Coaches frequently use small-sided games with numerical inequalities. However, it is unclear if these games accurately represent official matches. This study aims to identify the differences in external load between small-sided games and official matches among professional soccer players, incorporating the variance due to positional roles. Material and Methods. The analysis used GPS data collected from 20 professional football players from Turkish Super League club's first team during the 2023-2024 season. The small-sided games (SSGs) were structured as 4vs4+3, including three joker players. Players were divided into five groups based on their field positions: central defenders, fullbacks, midfielders, wingers, and forwards. The GPS metrics recorded included total distance (m), moderate-intensity running distance (16-20 km/h), high-intensity running distance (20-25 km/h), sprint distance (>25 km/h), the number of accelerations and decelerations, and high metabolic power distance, both in absolute and relative terms. Furthermore, the SSGs were compared based on the number of days prior to official matches when they were conducted. Results. The findings revealed that the highest values for all external load variables were recorded 4 to 5 days before official matches (p<0.001). However, the per-minute acceleration rate (2.5003 +/- 1.09288) and deceleration rate (2.4971 +/- 1.10671) in the SSGs were significantly higher than those observed in official matches (p<0.001). Conclusions. Coaches and conditioning trainers aiming to simulate match conditions in training should consider using 4vs4+3 SSGs with joker players more tactically. This approach is especially effective for enhancing possession, creating numerical superiority, and focusing on performance metrics such as acceleration and deceleration.

    Evaluation of repeated sprint test protocols used in soccer with a global positioning system
    (Iermakov S S, 2022) Kaya, Kaan; Gurol, Baris
    Background and Study Aim Material and Methods The aim of the research is to evaluate the 7x34.2 m Repeated Straight Sprint Test (RSST) and 7x34.2 m Repeated Change of Direction Sprint Test (RCST), which are used for improvement, measurement, and evaluation of repeated sprint ability, by using Global Positioning System (GPS). Twenty-two professional soccer players participated in the research voluntarily. Internal and external load data were examined comparatively by using data as before and after the repeated sprint tests. External load data measured by 10 Hz GPS. Results When the findings of the research are examined, it is seen that values of blood lactate concentrations which are taken after three and five minutes of the RCST are significantly higher than RSST protocol (p < 0.001***, p = 0.042*, respectively). In the study, the value of lactate which is taken five minutes after the RSST was measured as 9.60 +/- 2.65 mM, while the value which is taken three minutes after RCST was measured as 9.75 +/- 2.51 mM. Nevertheless, whereas there was a difference between the two tests in terms of lactate values, no significant difference was found in terms of perceived exertion. Conclusions As a conclusion, according to the analyzes made after the RCST and RSST, we can say that the internal and external load performances of the athletes were very different. It has been observed that coaches, athletes, and practitioners can use two different test protocols for different objectives according to the purposes they set.

    Statistical Analysis for Various Parameters of an International Functional Training Competition in Turkey
    (Çanakkale Onsekiz Mart Üniversitesi, 2022) Ocak, Muhammed Hüseyin; Subak, Gülhan Erdem; Papur, Emincan; Kaya, Kaan; Viga, Onur
    Purpose: The number of Crossfit competitions held is increasing day by day. The factors affecting the results in these competitions have become an important research topic. This study aimed to analyze whether the results of an international Crossfit competition held in Turkey differ according to the age, height, bodyweight, training time, number of daily steps, and athlete history parameters of the competitors. Method: The competition consisted of six stages and includes eight categories created according to the level of the athletes. For the study, a questionnaire containing this information was applied to the competitors (n = 184; 133 men, 51 women) and the data obtained were statistically compared with the scores at the end of the competition. Results: The findings of this study showed that age, height, body weight, exercise duration, and athlete history parameters affected the results of the functional training competition. In particular, it was observed that the height factor significantly affected the results of the competition, and the tall athletes scored better in most categories (p < 0.05). In addition, it was observed that age and body weight parameters created significant differences in some categories and some stages. It has been determined that the competitors with more than 10,000 daily steps were more unsuccessful in the total ranking. The daily exercise time of the athletes who were successful in the competition was 75-90 minutes. It has been noted that they did Crossfit training 5 days a week and that all finalist athletes were also interested in sports branches other than Crossfit. Conclusion: The findings of this research can provide enlightening information about the parameters that should be taken into account by the organizers of Crossfit competitions during the preparation phase of the competition content and the athletes during the preparation phase for these competitions.
