Abstract

This study was
carried out to determine the relation between patellofemoral (Q) angle
differences and static equilibrium, flexibility and take-off force in young and
veteran volleyball players. To the study 20 young males with an average age of
18 ± 00, 19 young females with a mean age of 18 ± 73, 21 veteran males with a
mean age of 49 ± 04, 20 veteran females with a mean age of 48 ±70 who are
registered players in Muğla Provincial Directorate of Youth and Sports, a total
of 80 athletes voluntarily participated. The height, body weight, right and
left leg Q angles in standing and laying, balance, flexibility and vertical
take-off measurements were performed in the research group respectively. The
statistical evaluation of the obtained data was done in SPSS 21.00 package
program on a personal computer. In the data with normal distribution, the
parametric statistical methods were used. While the analysis of variance
(ANOVA) test was used for intergroup comparisons, the Tukey test was used for
multiple comparisons, and the correlation level was used to determine the
relationship between the variables and the significance level was taken as p
<0.05. According to the findings, there were significant differences between
the Q angles, balance, flexibility, and take-off values of the participants (p
<0.01). Also, there was a positive relationship between Q angle values and
elasticity values in standing and laying position, and a negative relationship
between balance and take-off force values (p <0.05).

As a
result: Q angle values of volleyball players were examined and it was
seen that the difference between groups has resulted from gender; the
difference between young and veteran volleyball players was not statistically
significant. As the Q angle increased, the increase in the elasticity values
and the decrease in the balance and splash values were determined. In this
respect, Q angle differences are thought to be related to lower extremity
performances of young and veteran volleyball players.
