The aim of this study was to compare bilateral and ipsilateral lower extremity strength asymmetry in male and female soccer players. This study was conducted with cross-sectional research model. A total of 74 soccer players, 36 women and 38 men, who play active soccer in Mersin, participated in the study voluntarily. The body composition of the participants was measured by bioelectrical impedance analysis and isokinetic strength was measured by Cybex II Norm isokinetic dynamometer. Isokinetic strength test was performed for both knees at 60 o/s for 3 sets 5 repetitions. Bilateral and ipsilateral force asymmetry were calculated with formulas based on peak torque force. Since bilateral force asymmetry values were not normally distributed, Mann Whitney U test was performed, and since ipsilateral force asymmetry values were normally distributed, independent sample t test was performed. When the bilateral strength asymmetry of male and female soccer players were compared, it was observed that there was a significant difference in both quadriceps (p<0.02) and hamstring muscle groups strength asymmetry (p<0.01). In the ipsilateral force asymmetry values, it was observed that there was no significant difference between genders (p>0.05). When the ipsilateral force asymmetry values were examined, it was observed that male soccer players (56.04%-55.21%) had more ideal values than females (54.49%-53.88%). As a result, in our study findings, it was observed that the strength asymmetry values of the athletes were at an ideal level and there was a difference between the genders in bilateral asymmetry, but there was no difference in ipsilateral asymmetry.

ÖZ
Bu araştırmada, kadın ve erkek futbolcuların alt ekstremite bilateral ve ipsilateral kuvvet asimetrisinin karşılaştırılması amaçlanmıştır. Bu çalışma, kesitsel araştırma modeli ile gerçekleştirilmiştir. Araştırmaya Mersin ilinde aktif futbol oynayan 36 kadın 38 erkek olmak üzere toplam 74 futbolcu gönüllü olarak katılmıştır. Katılımcıların vücut kompozisyonu ölçümleri bioelektrik impedans analizi ile izokinetik kuvvet ölçümleri ise Cybex II Norm izokinetik dinamometre ile ölçülmüştür. İzokinetik kuvvet testi 60 o/s’ de 3 set 5 tekrar olmak üzere her iki diz için de uygulanmıştır. Bilateral ve ipsilateral kuvvet asimetrisi zirve tork kuvveti üzerinden formüller ile hesaplanmıştır. Bilateral kuvvet asimetrisi değerleri normal dağılım göstermediği için Mann Whitney U testi, ipsilateral kuvvet asimetrisi değerleri normal dağılım gösterdiği için bağımsız örneklem t testi yapılmıştır. Kadın ve erkek futbolcuların bilateral kuvvet asimetrisi karşılaştırıldığında hem quadriceps (p<0,02) hem de hamstring kas grupları kuvvet asimetrelerinde (p<0,01) anlamlı farklılık olduğu görülmüştür. İpsilateral kuvvet asimetrisi değerlerinde ise cinsiyetler arasında anlamlı farklılık olmadığı (p>0,05) gözlemlenmiştir. İpsilateral kuvvet asimetri değerlerine bakıldığında erkek futbolcuların (%56,04 - %55,21) kadınlara oranla (%54,49 - %53,88) daha ideal değerlere sahip olduğu gözlenmiştir. Sonuç olarak, çalışma bulgularımızda, sporcuların kuvvet asimetrisi değerlerinin ideal düzeyde olduğu ve cinsiyetler arasında bilateral asimetride fark olduğu, ipsilateral asimetride ise farklılık olmadığı görülmüştür.
