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.

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.

With compulsory distance education in Turkey during the pandemic, the positive and negative effects of distance education have been investigated. In this study, the views of 256 students (162 males, 94 females) with a mean age of 21.5±3.457, studying in various departments in the primary field of sports sciences at state (n = 95) and foundation (n = 161) universities, on distance education and face-to-face education. It was taken with the Attitudes towards Distance Education Scale and compared statistically. In addition to frequency and distribution analysis, an Independent Sample T-Test was applied for statistical analysis, and the confidence interval was determined as 95% (p < 0.05). As a result of the research, it was seen that the students found face-to-face education more effective. It was noted that students who found face-to-face teaching more effective than other students agreed with the view that distance education is not engaging with a significant difference (p < 0.05). The same students also stated that they disagreed with the opinions that qualified results can be obtained from distance education applications. According to students ‘ opinions, this study provides educators with information about some of the missing points of distance education compared to face-to-face teaching. The minus points of distance education can be detailed with surveys to be made with more participants.

Background and Study Aim. 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). Material and Methods. 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.
