The purpose of the present study was to determine the relationship among leg volume, leg mass and H/Q ratio with anaerobic performance and isokinetic knee strength in athletes from different sport branches. A total of 41 male athletes from basketball (n= 12), volleyball (n=14) and football (n=15) participated in this study voluntarily. Athletes’ leg volume (LV) was determined by Frustum method and leg mass (LM) was determined by Hanavan model. Anaerobic performances of athletes was determined by Wingate anaerobic power test and isokinetic knee strength and H/Q ratio was determined at 600s-1and 3000s-1. In football players significant correlations was obtained between right 60º.s-1 H/Q ratio and relative mean power (RMP) (r=-.552; p<0.05), right 60º.s1 knee extension strength (KES) (r=-.586; p<0.05), right 300º.s-1 KES (r=-.589; p<0.05), right 60º.s-1 knee flexion strength (KFS) (r=-.558; p<0.05). Left 60º.s-1 H/Q was significantly correlated with RMP (r=-.561; p<0.05), right 60º.s-1 KFS (r=-.698; p<0.01), right 300º.s-1 KFS (r=.622; p<0.05), left 60º.s-1 KES (r=-.613; p<0.05). A similar relation was obtained between right 300º.s-1 H/Q and right KFS (r=-.537; p<0.05).Left 300º.s-1 H/Q on the other hand was significantly correlated with left 60º.s-1 KFS(r=-.528; p<0.05). In basketball players significant correlations was obtained between right LV and peak power (PP) (r=.738; p<0.01), relative PP (RPP) (r=.650; p<0.05), right 300º.s-1 KES (r=.697; p<0.01), left 60º.s-1 KES (r=.766; p<0.01), left 300º.s-1 KES (r=.818; p<0.01), left 300º.s-1 KFS (r=.748; p<0.01).

Left LV was significantly correlated with PP(r=.633; p<0.05), RPP(r=-.576; p<0.05), left 60º.s-1 KES (r=.757; p<0.01), left 300º.s-1 KES (r=.866; p<0.01), right 300º.s-1 KFS (r=.753; p<0.01), left 300º.s-1 KFS (r= -.818; p<0.05) and Left leg mass (LM) was significantly related with PP (r=.669; p<0.05),

A similar relation was obtained between left 60º.s-1 H/Q and PP(r=-.663; p<0.01), RPP (r=.857; p<0.01), RMP(r=-.849; p<0.01), right 60º.s-1 KES (r=.620; p<0.01), left 60º.s-1 KES (r=.809; p<0.01), right 60º.s-1 KFS (r=-.727;

Bu çalışma farklı spor dallarındaki sporcularda bacak hacmi, kütlesi, hamstring/quadriceps oranı ile anaerobik performans ve izokinetik bacak kuvveti arasındaki ilişkinin belirlenmesi amacıyla yapılmıştır. Çalışmaya basketbol (n= 12), voleybol (n=14) ve futbol (n=15) branşlarında toplam 41 erkek sporcu gönüllü olarak katılmıştır. Sporcuların bacak hacmi Frustum yöntemi ile, bacak kütlesi ise Hanavan yöntemi ile belirlenmiştir. Anaerobik performansın belirlenmesinde Wingate anaerobik güç ve kapasite testi kullanılırken izokinetik kuvvetin belirlenmesinde konsantrik diz fleksiyon ve ekstansiyon kuvvetleri ve H/Q oranı için 60º ve 300º’lik hızlar kullanılmıştır.
