Olimpik bir spor olan eskrim epe, flöre ve kılıç branşlarından oluşmaktadır. Maçlar sırasında sporcular dominant kolda silahı tutarlar ve dominant bacak önde iken ileri, geri, yanlara adımlamalar yaparak savunma veya atak pozisyonunda olurlar. Kronik uygulamalara bağlı olarak dominant ekstremite ile non dominant taraf arasında yapısal ve- veya fonksiyonel asimetriler, enine kesit alanı ve performans ölçümleri ile gösterilmektedir. Bu araştırmanın amacı epe eskrimcilerinde dominant ve non dominant diz fleksiyon- ekstansiyon kuvvet değerlerini karşılaştırmaktır. Çalışmaya yaş ortalaması 18,1± 1,4 yıl olan 9 erkek sporcu katıldı. Kuvvet ölçümleri dominant ve non dominant dizde izokinetik dinamometrenin Cybex II konsantrik ve izometrik modülleri kullanılarak yapıldı. Açısal hızlar 240- 180- 120- 60⁰/sn olarak belirlendi ve her hızda 5 tekrar yapıldı. En yüksek değer maksimal kuvvet olarak değerlendirmeye alındı. İzometrik kasılma 60⁰ diz eklem açısında full ekstansiyon 0⁰ kabul edildiğinde 5 sn süre ile yapıldı. Hamstring/Quadriceps oranları her açısal hızda fleksör ve ekstensör kas kuvvetlerinin oranı ile hesaplandı. Sonuçlar bağımsız gruplarda t testi ile analiz edildi ve aritmetik ortalama±standart hata olarak verildi. Ekstansiyon hareketinde 240⁰/sn, 180⁰/sn, 120⁰/sn ve izometrik kasılmada dominant bacaktaki kuvvet değerlerinin nondominant bacaktan istatistiksel olarak anlamlı oranda yüksek olduğu bulundu p

EVALUATION OF BILATERAL ASYMMETRY OF CONCENTRIC AND ISOMETRIC KNEE EXTENSION- FLEXION STRENGTH IN MALE FENCERS

Öz

Fencing is an Olympic combat sport in which two athletes fight through their weapons such as epee, foil and sabre. During the competition, athletes hold the weapon with their dominant arm and stay in defense or attack positions by stepping forward, behind or right/left with dominant leg in front. Depending upon chronic applications structural and/or functional asymmetries between dominant and non-dominant extremities are shown with cross-sectional area and performance measurements. The aim of this study was to compare dominant and non-dominant knee flexion-extension strength values of epee fencers. The study was conducted on nine athletes whose age average was 18,1± 1,4 years. Strength measurements of dominant and non-dominant knees were carried out by using concentric and isometric modules of isokinetic dynamometers Cybex II . Angular velocities were determined as 240- 180- 120- 60⁰/s and 5 repetitions were done at each velocity. The highest value was accepted as the maximal strength. Isometric contraction was carried out at 60⁰ knee joint angle when full extension is accepted as 0⁰ during 5 seconds. Ratios of Hamstrings/ Quadriceps were calculated with ratios of strength of flexor and extensor muscles at every angular velocity. Results were analyzed with independent sample t-test and data were given as ±SEM. Strength values of dominant leg were found statistically significantly higher than those of non-dominant leg in 240⁰/s, 180⁰/s, 120⁰/s extension movement and isometric contraction p
