Investigation of the Relationship Between Patellofemoral (Q) Angle Differences With Lower Extremity Performance in Young and Veteran Volleyball Players

Abstract

This study was carried out to determine the relation between patella femoral (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 takeoff 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 Turkey 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.
