POWER AND STRENGTH LEVELS OF
ELITE FEMALE VOLLEYBALL PLAYERS
ABSTRACT
The aim of this study was to examine some power and strength properties of female
elite volleyball players. Eleven elite state-level of club teams players in Izmir-Turkey,
volunteered for the present study.
Physical characteristics as stature, weight, height, BMI and body fat ratio (by Yuhazs
method) of participants were evaluated respectively and performance characteristics as
vertical jumping (by jumpmeter), anaerobic power and capacity (by Wingate Anaerobic
Power Test), and isokinetic knee strength (by isokinetic dynamometer) and also left and right
hand grip strength (by hand-grip dynamometer), leg and back strength (by back-grip
dynamometer) and aerobic power (by Astrand Rhyming Test) were determined respectively.
The strength of knee extensors and flexors were measured bilaterally by using an Cybex II at
60, 180, 300 deg/s. Peak torque (Nm) and peak torque/body weight (Nm/kg), total work (J)
and average power (W) of isokinetic hamstring and quadriceps and also H/Q ratios, which are
important of the prevention of injuries, were determined and differences of the legs were
compared.
End of the tests, who had at least 6 years’ sport carrier, players’ ages were 22.18
(year), BMI were 21.52 kg/cm 2 , body fat ratios were 14.25±1.62 %, vertical jumping heigths
were 49.54±4,22 cm, anaerobic powers and capacities were 10.58±1,52 W/kg and 7.34±0,58
W/kg, and also heigths were 179,82±5,25 cm, weigths were 69.63±6,22 kg, right and left
hand grip strengths were 29.15±5,04 and 27.51±3,37 kg, back and leg strengths were
101.59±21,12 and 84,87±32,67 kg, aerobic powers were 45.94±8,19 cc/dk/kg.
The obtained findings were analyzed, whether there were statistical differences
between the legs through the Wilcoxon Test, by using SPSS 10.0. A P-value of < 0.05 was
adopted for test of statistical significance. All results were expressed as the mean and standard
deviation. The results were compared to those found in the literature for other populations of
the athletes, where available.
Results were consistent with existing studies on elite Turkish female athletes.
However, since it has been showed that H/Q ratios uploads with increasing velocities in many
foreign studies, degradation H/Q ratios at 300 deg/sec in our findings is conflicting. Peak
torques of right leg were higher than left side at 180 ve 300°/sec (p
