nvestigation of Gender Differences Related toKnee Strength Asymmetry

Öz:

Objectives: Inter-limb strength asymmetry is one of the major risk factors for noncontact injuries in sport. The determination of strength asymmetry provides an important information to develop different strategies for injury prevention and risk management in sport. It is not well-known whether inter-limb strength asymmetry differences exist between genders. The aim of this study was to determine the contralateral knee strength asymmetry differences between genders. Material and Methods: Thirty-three physically active but not highly-trained individuals (Age: 21.4±2.9 years, height: 1.75±0.07 m, body weight: 66.2±9.6 kg, body fat ratio: 15.2±5.7 %, BMI: 21.6±2.3 kg/$m^2$) voluntarily participated in this study. Approximately one week after the familiarization phase, all subjects performed knee isokinetic strength tests at slow (60°.$s^{-1}$), medium (180°.$s^{-1}$) and fast (300°.$s^{-1}$) angular velocities for right and left knee flexion-extension movement. The symmetry angle formula was used to calculate the contralateral strength asymmetry scores between lower-limbs. The differences between symmetry angles and genders were analyzed using independent sample t-test.Results: It was found that flexion and extension isokinetic contralateral knee strength asymmetry scores at slow, medium and fast angular angular velocities did not reveal any statistically significant differences between genders (p>0.05).Conclusions: It has been found that there were no differences between concentric isokinetic knee strength symmetry angle scores between genders at all angular velocities in physically active but not highly-trained individuals.

Amaç: Ekstremiteler arası kuvvet asimetrisi temassız spor yaralanmaları açısındanönemli bir risk faktörüdür. Kuvvet asimetrisinin belirlenmesi, spor yaralanmalarındankorunma ve risk yönetimi konusunda spor sağlık bilimcilerine farklı stratejilergeliştirebilmeleri için bilgi sunmaktadır. Fakat kuvvet asimetrisi yönünden cinsiyetlerarası farklılıklar net olarak bilinmemektedir. Bu çalışmanın amacı, kontralateral dizeklem kuvvet asimetrisini ve cinsiyetler arası farklılıkları belirlemektir. Gereç ve Yöntemler: Bu çalışmaya 33 birey (Yaş: 21.4±2.9 yıl, boy: 1.75±0.07 m,vücut ağırlığı: 66.2±9.6 kg, vücut yağ oranı: %15.2±5.7, beden kitle indeksi (BKİ):21.6±2.3 kg/$m^2$ ) gönüllü olarak katıldı. Tüm katılımcılar deneme ve tanıtım seansındanyaklaşık bir hafta sonra, düşük (60°.$s^{-1}$ ), orta (180°.$s^{-1}$ ) ve yüksek (300°.$s^{-1}$ ) açısalhızlarda sağ ve sol izokinetik konsantrik diz fleksiyon ve ekstansiyon kuvvet testlerinekatıldılar. Alt ekstremiteler arası kontralateral kuvvet asimetrisi değerlerini belirlemekiçin simetri açı formülünden yararlanıldı. Simetri açı değerleriyle cinsiyetler arasında fark bağımsız örneklem T-testi ileincelendi. Bulgular: Analizler sonucunda; düşük, orta ve yüksek açısal hızlardaki kontralateral fleksiyon ve ekstansiyonizokinetik diz kuvvet asimetrisi değerlerinin, kadın ve erkek grupları arasında istatistiksel olarak anlamlı bir farklılıkgöstermediği ortaya kondu (p>0.05).Sonuç: Elde edilen bulgular doğrultusunda; fiziksel olarak aktif ancak üst düzeyde antrenmanlı olmayan bireylerdedüşük, orta ve yüksek açısal hızlardaki kontralateral izokinetik diz kuvvetleri simetri açı değerlerinin kadın veerkeklerde benzer olduğu sonucuna ulaşıldı.
