Providing muscular strength balance is an important factor in both improving sport performance and preventing sports injuries. The aim of the current study is to determine the leg and shoulder muscle strength ratios of elite female volleyball players. 14 elite voluntary female volleyball players were included in the study. Dominant (D) and nondominant (ND) knee and shoulder muscle strength ratios of volleyball players who participated in the study were determined by isokinetic dynamometer at 60 ° s-1 and 180 ° s-1 angular speeds. Bilateral force differences (BLD), leg hamstring / quadriceps ratio (H/Q) and shoulder external / internal ratio (E/I) averages and standard deviations were determined for the leg and shoulder muscles after the obtained data were applied to the SPSS program. Statistical analysis revealed that the H/Q ratio was low and the E/I ratio was high at 60°s-1 and 180°s-1 angular velocities. It was also been determined that the BLD of the shoulder muscles was high while the BLD of the leg muscles was at the desired level at 60°s-1 and 180°s-1 angular speeds. As a result, the volleyball players participating in the study seem to have lower leg muscle strength and lower H/Q ratio. Furthermore, although it is thought that more work is done with the upper extremity in the volleyball, it can be said that lower extremity force development should not be ignored since it is a well-known fact that the entire body is carried by the lower extremity to change rapidly.

Bu çalışmanın amacı, sedanter kadınlara uygulanan 8 haftalık reformer pilates egzersizlerinin vücut kompozisyonu ve bazı fiziksel uygunluk parametrelerine etkisinin incelenmesidir. Çalışmaya dokuz sağlıklı sedanter kadın (yaş= 29±7,12) gönüllü olarak katılmıştır. Katılımcıların vücut yağ yüzdesi, çevre ölçümleri, sırt ve bacak kuvveti, esneklik ve denge performansları çalışma başlamadan önce ve 8 haftalık antrenmanlar sonrasında olmak üzere iki kez ölçülmüştür. Reformer pilates egzersizlerinin ön test-son test sonuçları arasındaki farkı belirlemede nonparametrik testlerden Wilcoxon testi kullanılmıştır. Yapılan istatistiksel analiz sonuçlarına göre 8 haftalık reformer pilates egzersizlerinin vücut yağ yüzdesini, çevre ölçümlerini (bacak, basen, bel ve göğüs bölgeleri) ve fiziksel uygunluk parametrelerini (esneklik, denge, kuvvet, vücut yağ yüzdesi) istatiksel olarak anlamlı şekilde geliştirdiği belirlenmiştir. Sonuç olarak reformer pilates egzersizlerinin, fiziksel uygunluk düzeyini geliştirme ve korumada bir alternatif yöntem olarak kullanılabileceği söylenebilir.

The aim of this study is to investigate the relationship between Functional Movement Screening (FMS) test scores and athletic performances of professional football players. Twenty professional male football players participated in the study voluntarily. Functional movement patterns of the players were determined by FMS test kit and athletic performances were determined by Yoyo test, T drill test, vertical and horizontal jump test, 10 m and 20 m speed test. Spearman Correlation Analysis was used to determine the relationship between FMS test scores and athletic performances of football players. As a result of the study, no statistically significant relationship was found between FMS test scores and athletic performances of football players (p<0.05). In addition, the FMS test total score of the players (14.2 points) was found to be above the limit of injury (14 points). In conclusion, although FMS test scores provide important information about the quality of functional movements and the likelihood of injury, it is not a determinant of athletic performance. This may be due to the combination of several motoric characteristics of athletic performance, although FMS test scores are assessed individually.

The purpose of the study was to examine the relationship between isokinetic wrist and shoulder strength and service and spike velocity of the female volleyball players. Totally 34 female volleyball players participated into the study voluntarily. Wrist (60°s-1 and 90°s-1) and shoulder strength (60°s-1 and 180°s-1) of the volleyball players were determined with isokinetic dynamometer; and service and spike velocity was determined with radar device. Pearson Correlation Analysis was performed for determining the relationship between isokinetic wrist and shoulder strength and service and spike velocity of the volleyball players. As result of the statistical analysis, whereas no significant relationship was determined between wrist and shoulder isokinetic strength and service and spike velocities of the female volleyball players (p<0,05), positive significant relationship was found between wrist and shoulder isokinetic strengths (p<0,05). Considering these results, it was possible to mention that although service and spike velocities of the volleyball players were correlational with the upper extremity strength, only wrist or only shoulder strength did not increase the velocity of service and spike, and this appeared by the effect of all upper extremity and bodily muscles. Regarding this, it was considered that volleyball players should develop other variables (strengthening all upper extremity and bodily muscles, improving the technique of spiking, etc.) besides wrist and shoulder strength in order to improve their service and spike velocity.
