The aim of this study was öto examine relationship among stability, speed and agility at female soccer players. The twenty-threee female soccer players participated in this study voluntarily (n=23, age=15.69±1.39 years, height=161.33±5.48 cm, weight=55.04±8.44 kg). The stability parameters of female soccer players were measured as static stability at opened and closed eyes positions and dynamic stability by stability measurement device. The 10, 30 and 40 meters sprint tests ans Illinois agility test were performed on synthetic turf soccer pitch by electronic photocell system. The 10, 30 and 40 meters sprint and Illinois agility test durations were determined. All tests were performed on different days and at the same time of day. The relationship stability, speed and agility parameters was determined by Pearson and Spearman correlation coefficients. According to analyze results, there was no significant correlation among stability, speed and agility parameters except for the correlation between the 30 meters sprint values and ATE (average track error) values from stability parameters. Consequently, it might be said that there was no significant relationship among stability, speed and agility parameters of female soccer players and stability ability at female soccer players could not be affected by speed and agility abilities.
Background. Simultaneous tiredness of two or more muscles around a joint can be defined as coordinated fatigue (cofatigue) and might occur between agonist and antagonist muscles, and vary according to the level of sporting activity levels or gender. Objectives. The aim of this study was to determine the levels of coordinated fatigue in agonist and antagonist muscles during squat-press exercise. Methods. Twenty athletes and twenty sedentary subjects participated in the study. Surface electromyography signals of the rectus femoris, vastus lateralis obliquus, biceps femoris and semitendinosus muscles were recorded at the squat press position for 15 seconds during isometric contraction. Measurements were repeated five times and a 2-minute rest period was allowed between repetitions. After erroneous EMG elimination, movement artefacts were removed by using a 20 Hz high-pass Butterworth filter. Then, as a wellrecognized fatigue index, the median frequency (MF) of each filtered middle part of the EMG signal (5 to 10 s. of contraction) was calculated, given that it is known that the MF decreases during isometric contractions. Finally, each MF-based co-fatigue index was calculated by dividing the mean RF and VLO median frequencies by the mean ST and BF median frequencies. The cumulative co-fatigue values of "male vs. female" and "sedentary vs. athlete" comparisons were performed by using a two-sided Student t-test with a Bonferroni correction. Results. There was a statistically significant (Bonferroni corrected p-value < 0.05) difference between the mean female (1.57 0.53) and the mean male (1.23 0.17) co-fatigue values, while there was no statistically significant difference between the mean co-fatigue values of sedentary (1.51 0.52) and athlete (1.29 0.27) subjects. Conclusion. The offered co-fatigue indices might be useful for other sports, physiotherapy and related areas if sufficient scientific proof is accumulated.
The aim of this study was to compare the relationship between physical education and sports high school students' positive thinking skill levels and attitudes of learning in terms of gender and years of doing sports. The study is a descriptive method, one of the quantitative research methods. The study group consisted of 280 (age: 20.98 ± 1.390) university students from School of Physical Education and Sports in Ordu university. As a result, it was concluded that the students' positive thinking skills were at a high level, and the nature of learning, anxiety, expectation, and openness to learning sub-dimensions of the attitude tolearning scale were at high levels. It was concluded that there is a statistically significant and positive relationship between the nature of learning, Expectation, and openness to learning, and positive thinking skill from sub-dimensions of the attitude to learning scale, but there is a negatively significant relationship between anxiety and positive thinking skills
Three-dimensional reconstruction of columna vertebralis ımages of elite male weightlifters taken by a multidetector computerized tomography (MDCT). Int. J. Morphol., 32(4):1184-1189, 2014. SUMMARY:This study aims to carry out a comparative study on the vertebral structure of the elite male weightlifters and the sedentary group (control group) by obtaining three-dimensional data and models by means of photogrammetry from the columna vertebralis sections taken by MDCT. The columna vertebralis of the 8 male weightlifters and 8 sedentary individuals (control group) was scanned with a high-definition diagnostic MDCT device during the study. The demographic findings suggest no difference in both the weightlifters and the sedentary individual. The 2D axial images in DICOM format were burnt on CDs and then copied on a PC on which 3D-Doctor 4.0, which is a 3D modelling program had already been installed. The reconstruction was carried out with the 3D rendering component of the program. All the data were automatically measured by the abovementioned program and the statistical analyses were determined with a -t test by SPSS 15. Considering the statistical results of the Columna vertebralis, only in the length of Pars lumbaris some statistically considerable differences (p<0.05) were observed between the vertebras L3-L5 in the elite male weightlifters and the sedentary individuals. Therefore, concluding from the idea that these techniques and the three-dimensional reconstruction procedures should be put into practice in the field of sports medicine, the substructure works that will be carried out on weightlifters by means of MDCT are thought to be supported by these studies.
Bu çalışmanın amacı, genç kadın futbol oyuncularının çeviklik, sürat ve reaksiyon sürati parametreleri arasındaki ilişkilerin incelenmesidir. Araştırmaya Türkiye Kadınlar Futbol 3. Liginde mücadele eden bir futbol kulübünde futbol oynayan 18 amatör genç futbol oyuncusu gönüllü olarak katılmıştır (n=18, yaş: 17,50±1,38 yıl, boy uzunluğu=161,71±5,03 cm, vücut ağırlığı=55,86±9,50 kg). Oyuncuların çeviklik değerini belirlemek için çeviklik T testi, sürat değerlerini belirlemek için 10, 30 ve 40 m sürat testleri, görsel ve işitsel reaksiyon sürati değerlerini belirlemek için ışık ve ses uyaranlarına karşı reaksiyon verilmesini gerektiren basit reaksiyon sürati testleri uygulanmıştır. Testlerden elde edilen çeviklik, sürat ve reaksiyon sürati değerleri arasındaki ilişkileri belirlemek için, korelasyon analizi tekniği kullanılmış ve parametreler arası ilişkiler Pearson korelasyon katsayısıyla belirlenmiştir. Analiz sonuçlarına göre, genç kadın futbol oyuncularının 10 m sürat değerleriyle dominant el işitsel reaksiyon sürati değerleri arasında istatistiksel açıdan anlamlı düzeyde bir ilişki belirlenmiş (r=0,489, p<0,05), diğer parametreler arasındaki Pearson korelasyon katsayıları istatistiksel olarak anlamlı bulunmamıştır. Reaksiyon sürati değerlerinin kendi arasındaki korelasyon katsayılarına göre, dominant el görsel reaksiyon sürati değerleriyle dominant olan ve dominant olmayan el işitsel reaksiyon sürati değerleri arasındaki ilişki istatistiksel açıdan anlamlı bulunurken, dominant olmayan el görsel reaksiyon sürati değerlerinin ise sadece dominant olmayan el işitsel reaksiyon sürati değerleriyle istatistiksel açıdan anlamlı düzeyde bir ilişkiye sahip olduğu belirlenmiştir (p<0,05). Sonuç olarak, genç kadın futbol oyuncularında 10 m sürat değerleriyle dominant el işitsel reaksiyon sürati değerleri arasındaki ilişki haricinde çeviklik, sürat ve reaksiyon sürati parametreleri arasında ilişki bulunamadığı ve bu durumun parametreler üzerinde etkili olan fizyolojik ve motorik mekanizmaların farklılaşmasından kaynaklanabileceği söylenebilir.
