Öğe The correlation between some physiological and motor parameters in elite football players according to playing positions(Editura Universitatii din Pitesti, 2024) Aksoy, Ömer; Soyal, Mehmet; Caba, Uğur; Başkan, Ali Nadir; Karadağ, Ayşe DemetObjective of the Study: Due to the different tasks of football players playing in different positions during the competition, their workload and energy needs also change and accordingly the necessity of special training planning arises. In this context, the aim of this study is to examine the correlation between sprint, counter movement jump, agility and endurance parameters of elite football players according to their playing positions. Method: The research model was determined as a correlational survey model from survey models. A total of 65 volunteer male footballers competing at U14 elite level in Turkish leagues participated in the study. The body weight (kg) values of the participants were measured using an electronic weighing machine (Tanita TBF 401 A, Japan) with an accuracy of ± 100 g, and their height (cm) was measured using a digital height measuring device with an accuracy of 0.01 cm. The counter movement jump parameter of the footballers was measured by Smartjump Vertical Jump Testing, their agility parameter was measured by Pro-Agility test protocol, their sprint parameter was measured by Smart Speed and Fusion Sport photocell, and their endurance parameter was measured by Yo-Yo IR1 tests. SPSS 24 software was used to analyze the data. The Pearson’s Correlation Analysis method was applied to determine the correlation between the performance parameters of the football players in terms of the positions. Findings: The findings of the study revealed that there was a high positive correlation (r=.784, p=0.037) between the agility parameter and 0-30 m sprint parameter and a high positive correlation (r=.782, p=0.038) between the 20-30 m sprint and 0-30 m sprint parameters of the goalkeepers. While a weak negative correlation (r=-.459, p=0.032) was found between the counter movement jump parameter and sprint parameter in defensive players, a moderate negative correlation was found (r=-.531, p=0.023) between these parameters in midfield players, and a moderate negative correlation was found (r=-.521, p=0.027) between these parameters in forward players. A positive moderate correlation was found between agility and 10-20 m (r=.530, p=0.024) and 0-30 m sprint parameters (r=.510, p=0.030), while a negative moderate correlation was found between 0-10 m sprint and 10-20 m sprint parameters (r=-.523, p=0.026). Moreover, there was a moderate positive correlation between 10-20 m sprint and 0-30 m sprint parameters (r=.533, p=0.023) and between 20-30 m sprint and 0-30 m sprint parameters (r=.580, p=0.012). Conclusion: Considering the positions and performance outputs of the football players in the field, it can be asserted that the intensity of the actions performed by the football players in the competition was mainly anaerobic, and success was based on especially the motoric characteristics in which the phosphagen system was active. © 2024, Editura Universitatii din Pitesti.

Method: The study was conducted using the one-group pretest-posttest weak experimental design, which is one of the quantitative research approaches. The sample group consisted of a total of 27 volunteer professional male football players competing at the Spor Toto Super League level of the Turkish Football Federation. Pretests were applied to the football players in the study before the preparation period and posttests were taken after the 6-week training program was applied. Before the test, football players were randomly divided into groups via minimization according to their pre-existing maximal aerobic speed (MAS). The other tests (strength, balance, flexibility, and vertical jump) were taken 48 hours after this test was administered. SPSS 24 software was used to analyze the data obtained from the study. With the normal distribution of the data, paired samples t-test analysis was performed to determine the test results of the same sample group in the pretest and posttest. Results: It was found that there was a statistically significant difference between the pretest and posttest values of the balance anterior right and balance anterior left parameters of the football players in the study (p<0.05), while no statistically significant difference was found between the pretest and posttest values of the other parameters (p>0.05). While there was a statistically significant difference between the football players’ pretest and posttest values of the endurance parameters MAS 400 m HR, MAS 600 m HR, and MAS 1000 m (sec.) (p<0.05), there was no statistically significant difference between the pretest and posttest values of the other parameters (p>0.05). It was found that there was a statistically significant difference between the pretest and posttest values of the strength parameters hip thrust AD/AB left, hip thrust AD/AB right, hip tightening AD/AB left, right, hip tightening AD/AB right, vertical jump (cm) and flexibility of the football players (p<0,05), while no statistically significant difference was found between the pretest and posttest values of the other parameters (p>0.05). Conclusion: It can be asserted that the athletic performance training applied to the football players during the preparation period contributed positively to their performance parameters such as balance, strength, endurance, jumping, and flexibility. However, in the current study, no statistically significant difference was found between the pretest and posttests of some parameters. Thus, it is thought that it will be important to prioritize proprioception and nordic hamstring trainings when designing training programs for players competing in football or other sports branches during the preparation period in future studies. © JPES.Öğe The examination of VO2MAX and anaerobic threshold values in elite soccer players by their positions(Editura Universitatii din Pitesti, 2022) Aksoy, Ömer; Bozdoğan, Tuba Kizilet; Soyal, Mehmet; Beyaz, Mehmet MuratObjective of the Study: This study was conducted to examine the parameters of maximal oxygen consumption capacity (VO2max), anaerobic threshold heart rate, endurance heart rate, and recovery heart rate in elite soccer players according to their positions (goalkeeper, defenders, midfielders, and forwards). Method: The relational screening model was used in the study. And the study group consisted of a total of 88 players, including goalkeepers (n:11), defenders (n:33), midfielders (n:30) and forwards (n:14), from different teams and positions in the Turkish Super League. The SensorMedics 29 c ergospirometry was used with the breath and breath method as per the maximal oxygen consumption in the data collection process. In addition, the exercise testing protocol was applied to the soccer players on the treadmill, and their pulse values were recorded instantly with the polar watch. Plus, the V-Slope method was used to determine the anaerobic threshold values. Moreover, while the SPSS 25.0 package program was used for statistical analysis, correlation analysis was performed for the comparison between positions. Findings: A strong positive correlation was found between the anaerobic threshold, endurance training, and recovery heart rates of the goalkeeper, defenders, midfielders, and forwards participating in the research. Then again, while a strong negative correlation was determined between age, endurance training heart rate, and recovery heart rates of defenders and forwards, no statistical difference was found between the age (year), height (cm) and VO2max (ml/kg/min.) parameters of the goalkeepers and midfielders and their other parameters. Conclusion: In conclusion, when the study results are evaluated, it is clear that the VO2max values of soccer players playing in different positions were close to each other. Also, it is concluded that the reason why the anaerobic threshold heart rate, endurance heart rate, and recovery heart rate parameters of the soccer players in different positions vary; Their actions in the competitions or training. © 2022, Editura Universitatii din Pitesti.

The questionnaire technique was used as the data collection method. Leadership and problem-solving skill scales were administered to the participants. A significantrelationship was found between leadership behaviours in sports and problem-solving skills (R=.588, R2=.345; p<.001). It was determined that with standardized regression coefficients (ß)=.588; t=.4,878; p=.000, leadership behaviour in sports positively affected problem-solving skills, and that it explained 34.5% of the total variance. It was determined that there were positive and weak, moderate, and high relationships between football coaches' leadership behaviours and problem-solving skills levels and that coaches' leadership behaviour in sports approaches had a considerable effecton their problem-solving skills.Öğe The relationship between FMS scores and lower body isokinetic strength in football players(Editura Universitatii din Pitesti, 2023) Soyal, Mehmet; Aksoy, Ömer; Karadağ, Ayşe Demet; Kiliç, Sefa; Bayazitli, Erhayat ÖzgürObjective of the Study: In football, one of the branches with a large audience in the world, it is thought that ever-increasing performance, the strengthening of competition and the desire to succeed as well as technicaltactical, psychological, and psychological needs and the improvement of physical and physiological characteristics at the most appropriate level will contribute positively to the performance of football players. Especially in football competitions, high-intensity actions may cause athletes to spend higher effort. Many qualities of football players should be improved to perform these actions at the most appropriate level and to protect them from injuries. For this purpose, the aim of this study is to investigate the relationship between FMS (Functional Movement Screen) scores and isokinetic lower body strength of football players. Method: The correlational survey model was preferred as the research model of the study. The sample group consisted of a total of 28 volunteer football players competing at the level of amateur league. The maximum strength of the knee extensor and flexor muscles of the participants was measured using an isokinetic dynamometer device (Cybex NORM®, Humac, CA, USA) that allows to record instantaneous isokinetic torque. The FMS test was applied to assess mobilisation and stabilisation of football players. SPSS 25.0 software was used for statistical analysis of the data and Spearman’s correlation analysis was used to compare the relationship between isokinetic lower body strength and FMS scores. Findings: When the FMS scores and right and left knee flexion/extension degrees were analysed, no statistically significant correlation was found between the parameters. Conclusion: The results of the statistical analysis revealed no correlation between FMS scores and right-left knee flexion and extension parameters of the amateur football players. Accordingly, it is suggested to include FMS applications in the training programmes of the football players and contribute to their performance by minimising their injuries and providing neuromuscular coordination and thus to make contribution to the related literature and to guide future studies. © 2023, Editura Universitatii din Pitesti.
