Purpose: The aim of study is to analyse isokinetic knee strength in soccer players in terms of selected parameters. Methods: A total of 30 subjects, 15 soccer players and 15 controls, were included in the study. Isokinetic knee strength measurements at angular speeds of 60°sec-1, 180°sec-1 and 240°sec-1 and pro-agility tests were conducted on the subjects. A body analyser was used for height, weight and body mass indexes (BMI) values. The training ages of the subjects and the positions of the soccer player group were recorded on personal information forms. Results: When the agility parameters were compared between football and control groups, a statistical difference was found in favour of the soccer player group (p < 0.05). When the effects of body composition and isokinetic knee strength on agility were analysed, negative significant correlation was found between weight and agility, BMI and agility and 240° right knee extension strength and agility (p < 0.05). When the positions of soccer players and isokinetic knee strengths were compared, significance was found between 60° right extension strength of defenders and midfielders and 60° left extension-flexion strengths of defenders and midfielders and forwards in favour of defenders (p > 0.05). Conclusions: In conclusion, it was found that isokinetic knee strength did not have an influence on agility in low angular speeds, except for 240°sec-1 right extension. According to positions, as the isokinetic knee strength of defenders decreased, they showed higher results when compared with other positions.

Background The aim of this study was to compare the effects of small-sided games (SSGs) and running-based high-intensity interval training (HIIT) on the body composition and physical fitness of youth female soccer players. Methods This study followed a randomized parallel study design. Twenty-four female soccer players (age: 18.63 ± 2.36 years) were randomly allocated to two training groups (SSG, n = 12; and HIIT, n = 12). The training intervention had a duration of eight weeks, consisting of three training sessions per week. Players were assessed twice (pre- and post-intervention) for anthropometrics, vertical (countermovement jumps, CMJ; and drop jumps, DJ) and horizontal jumping (single, triple and crossover hop), sprinting (10- and 30-m), change-of-direction (COD), COD deficit and final velocity at 30–15 Intermittent Fitness Test (VIFT). A covariance analysis (ANCOVA) was used to determine differences between the groups in the effect on post-intervention by controlling for covariates (pre-intervention). The within-group analysis (time) was performed using a paired t-test, while the between-group analysis per assessment moment was performed using an independent t-test. Results The between-group analysis with ANCOVA revealed that there are no significant differences between the SSG and HIIT groups in the post-intervention for any outcome (p > 0.05). The within-group analysis revealed significant improvements in both the SSG and HIIT groups in CMJ (p < 0.05), single, triple and crossover hops (p < 0.05), RSI DJ 30-cm and RSI DJ 40-cm (p < 0.05), VIFT (p < 0.05) and COD (p < 0.05). Conclusions SSG and HIIT are both effective for improving vertical and horizontal jumping ability, change-of-direction, and aerobic capacity status measured at a progressive and intermittent multistage test in youth soccer players.

Background and Objectives: Anterior cruciate ligament (ACL) tears are common injuries in the athletic population, and accordingly, ACL reconstruction (ACLR) is among the most common orthopedic surgical procedures performed in sports medicine. This study aims to compare the semitendinosus/gracilis (ST/G) and ACL hamstring grafts fixed using adjustable cortical suspension in both the femur and tibia (MAI) ACLR techniques. We aimed to compare the results of single-leg hop tests (SLHT) applied in different directions and limb symmetry indices (LSI) in athletes with a 6-month post-operative ACLR history. Materials and Methods: A retrospective cohort of 39 athletes from various sports branches who underwent MAI (n = 16) and ST/G (n = 23) ACLR techniques by the same surgeon were evaluated. The knee strength of the participants on the operated and non-operated sides was evaluated with five different SLHTs. The SLHT included the single hop for distance (SH), triple hop for distance (TH), crossover triple hop for distance (CH), medial side triple hop for distance (MSTH), and medial rotation (90°) hop for distance (MRH). Results: There was a significant improvement in the mean Lysholm, Tegner, and IKDC scores in the post-operative leg for both techniques (p < 0.05) compared to the pre-operative levels. When there was a difference between the SH of the operative and the non-operative legs in the ST/G technique (p < 0.05), there was no significant difference in the other hop distance for both ST/G and MAI (p > 0.05). There was no difference between the techniques regarding the LSI scores. Conclusions: The fact that our research revealed similar LSI rates of the SLHTs applied in different directions in the ST/G and MAI techniques assumes that the MAI technique can be an ACLR technique which can be functionally used in athletes.

Amaç: Meslek seçimi bireylerin yaşamlarını etkileyen en önemli faktörlerden birisidir. Kendine uygun mesleği seçen bireyler yaşam boyu mutlu olacağı gibi yaptıkları işte de verimli olacak, kendisine ve yaşadığı topluma daha çok fayda sağlayacaktır. Bu önemden hareketle, tanımlayıcı bir araştırma niteliğinde olan bu çalışma öğrencilerin meslek ve üniversite tercihlerini etkileyen etmenleri saptamak amacı ile yapıldı. Gereç ve Yöntem: Kesitsel tanımlayıcı nitelikte olan bu çalışma örneklemini Kırıkkale Üniversitesi Sağlık Bilimleri Fakültesi'ne 2009-2010 akademik yılında kayıt yaptıran öğrenciler oluşturdu. Bulgular: Araştırmaya katılan öğrencilerin %70.32'sinin kendi isteği ile tercih yaptığı, %45.05'inin İç Anadolu Bölgesi'nden geldiği ve %57,4'ünün ailesinin ekonomik durumunu orta olarak değerlendirdiği görüldü. Öğrenciler tercihlerini çoğunlukla 6-10. sıralarda yaptıkları ve çoğunluğunun tercih ettiği bölümle ilgili genel bilgiye sahip olduğu sonucuna varıldı. Sonuç: Üniversite tercihini etkileyen faktörler arasında; üniversitenin şehre olan mesafesinin daha etkili olduğu, şehrin sosyo-ekonomik düzeyinin, yurt ve barınma olanaklarının etkisinin düşük olduğu, öğretim elemanları ve akademik yapının etkisinin olmadığı sonuçlarına ulaşılmıştır.

The purpose of this study is to find out the narcissism levels of the students in Faculty of Sports Sciences and to compare these in terms of some demographic variables. The sample of the study consists of a total of 180 students (66 females, 114 males) studying in three different departments of faculty of sports sciences (Physical Training and Sports Education, Sports Management and Coaching Education) who agreed to participate in the study voluntarily. In the study, Narcissistic Personality Inventory was used as data collection tool. The normality assumption tests of the data were conducted with Kolmogorov-Smirnov Test. Since the data did not meet the parametric test assumptions, nonparametric tests "'Mann-Whitney U" and "Kruskal Wallis" were used in order to find out the differences between personality traits and narcissism. Significant differences were found between age and the sub dimensions of exhibitionism and entitlement, between year of study and entitlement, and between being elite and exhibitionism and exploitativeness (p<0.05). In addition, branches and all sub dimensions were compared and no significant difference was found in any of the sub-dimensions (p>0.05). No significant difference was also found between total narcissism scores and the variables. As a conclusion, statistically significant difference was found between students' narcissistic personality traits and the variables of age, year of study and being elite. Based on these results, the fact that the students show narcissistic personality traits although they are still students shows that it is necessary to take the necessary steps before these attitudes and perceptions reach harmful extents and continue increasingly in their occupations.
