    Relationship between ball speed in instep and inside foot kicks and anthropometric, motor, and anaerobic performance parameters in male football players
    (Iermakov S S, 2024) Karadenizli, Zeynep I.; Zileli, Raif; Ozkamci, Hueseyin
    Background and Study Aim. Football performance often depends on the ability to execute powerful and precise kicks. Understanding the factors influencing ball speed can help optimize training methods. The aim of this study is to investigate the relationships between ball speed in instep and inside foot kicks and some anthropometric, motor characteristics, and anaerobic performance parameters in male football players. Material and Methods. This study was conducted with 17 volunteer football players from the university football team. Their average age was 23.11 +/- 1.61 years. They had an average height of 177.52 +/- 6.14 cm, an average body weight of 76.25 +/- 5.74 kg, and an average body mass index of 24.20 +/- 1.55 kg/m(2). Participants underwent measurements for various anthropometric characteristics, including height, leg length, body weight, and thigh and leg circumferences. Motor characteristics measured included 30m sprint speed, vertical jump height, horizontal jump distance, and leg and grip strength. Anaerobic power was calculated using the Lewis formula. To determine ball speed, a radar (Sports Radar 3300) was used. The Shapiro-Wilk test determined the normality distribution, and the Levene test assessed variance homogeneity. Since the data showed parametric characteristics, Pearson correlation analysis was used. Statistical significance was initially set at p<0.05. All statistical analyses were performed using SPSS 21. Results. According to the findings, statistically significant differences were found between instep kick ball speed and inside foot kick ball speed (r = 0.65). Significant differences were also observed between leg length and shoe size (r = 0.61), and between anaerobic power and leg length (r = 0.67), thigh circumference (r = 0.51), and leg circumference (r = 0.53) (p < 0.05). No statistically significant differences were found among other parameters (p > 0.05). Conclusions. No significant relationships were found between ball speed in instep and inside foot kicks and anthropometric, motor, and anaerobic parameters in university male football players. This result may be attributed to the varying levels of the club teams to which the players of the university football team belong.

    Sprint and Anaerobic Power with the Soccer-Specific ACTN3 Gene: A Distintive Example
    (Soc Chilena Anatomia, 2024) Soyler, Mehmet; Zileli, Raif; Ozkamci, Huseyin; Diker, Gurkan; Sever, Mehmet Onur; Bayrakdaroglu, Serdar; On, Sadi
    The aim of this study is twofold: (1) to identify differences in certain anaerobic parameters (10m sprint, 30m sprint, anaerobic power, and Illinois agility tests) between professional and amateur soccer players, and (2) to determine whether there is a difference in the ACTN3 gene polymorphism between professional and amateur soccer players. Ultimately, the goal is to reveal which parameters contribute to the differentiation in these two aspects. A total of 133 volunteer soccer players, including 71 professionals and 62 amateurs, participated in the research. DNA extraction from buccal epithelial cells was performed using a commercial kit to determine the genetic background of the athletes, and Real -Time PCR was conducted for genotyping. Statistical analysis of the findings obtained from the test results was performed using the SPSS 23 (SPSS Inc., Chicago, IL, USA) package program. The homogeneity of variance of the data was assessed using the Levene Test, and normal distribution analyses were conducted using the Shapiro -Wilk Test. Chi-square and Mann -Whitney U tests were employed for parameter analysis. The significance level was set at p<0.05. Evaluation of the data in our study revealed no statistically significant difference in ACTN3 rs1815739 gene polymorphism between the groups (p>0.05). However, there is a statistically significant difference in anaerobic parameters (10m sprint, 30m sprint, and anaerobic power) except for the Illinois test (p<0.05). In conclusion, our study found that gene polymorphism is not a differentiating factor between professional and amateur soccer players, but speed (10m and 30m) and anaerobic power parameters are differentiating factors.

    The Distinguishing Factor in Soccer Players is Aerobic Performance, not the ACTN3 Gene
    (Soc Chilena Anatomia, 2023) Zileli, Raif; Soyler, Mehmet; Diker, Gurkan; Ozkamci, Huseyin; Bayrakdaroglu, Serdar; Sever, Mehmet Onur; Can, Ibrahim
    The purpose of this study was to reveal the differences between ACTN3 genotype (RR, RX, XX) and aerobic performance [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] in professional and regional amateur league soccer players and to reveal which of these parameters was a distinctive factor in these athletes.71 professional soccer players (age: 23.66 +/- 4.11 years; body height: 1.79 +/- 6.99 m; body weight: 76.02 +/- 6.76 kg; body fat: 11.59 +/- 3.11 %) and 62 regional amateur soccer players (age: 23.63 +/- 3.77 years; body height: 1.81 +/- 5.77 m; body weight: 76.36 +/- 7.53 kg; body fat: 15.60 +/- 4.65 %) volunteered for the study. After DNA extraction from buccal epithelial cells via a commercial kit was performed for the genetic background of the athletes, Real-Time PCR was carried out for genotyping. Furthermore, Yo-Yo IRT1 test was performed to determine the aerobic performance of the soccer players. SPSS 23 (SPSS Inc., Chicago, IL, USA) package program was used for the statistical analysis of the data obtained in the tests. Shapiro-Wilk test for normality and Levene's test for homogeneity of variance were performed. Chi-Square, Independent Sample T Test and One Way ANOVA test were used in the analysis of the parameters. Statistical significance was set as p<0.05. In the study, there found no meaningful statistical significance in terms of the rs1815739 polymorphism in the ACTN3 gene between the groups (p>0.05); however, there was a statistical significance in favor of professional soccer players in terms of aerobic parameters (p<0.05). Consequently, it can be said that aerobic performance is the distinguishing factor, not the ACTN3 gene, in soccer players.
