Abstract (2. Language):
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.s-
1 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). A similar
relation was obtained between right LV and PP (r=.618;
p<0.05) left 60º.s-1 KES (r=.766; p<0.01), left 300º.s-1 KES
(r=.866; p<0.01), right 300º.s-1 KFS (r=.840; p<0.01), left
300º.s-1 KFS (r=.832; p<0.01). On the other hand right 60º.s-1

(r=-.640; p<0.05). Right 300º.s-1 H/Q was significantly correlated
with PP (r=-.579; p<0.05), left 300º.s-1 KES (r=-.690;
p<0.05), right 60º.s-1 KFS (r=-.624; p<0.05), right 300º.s-1
KFS (r=-.940; p<0.01), left 300º.s-1 KFS (r=-.739; p<0.01). Left

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
