Abstract
Volleyball is one of the most popular sports in Iran, and participation in volleyball is on the rise. Pre-participation examinations, including musculoskeletal screening and functional performance testing, are an essential part of a multidisciplinary approach to prevent future injuries. Because the lower and upper extremities are the most commonly-injured body area in volleyball players, Assessing dynamic balance and postural control is of utmost importance. Therefore, the aim of this study was to determine if the lower and upper Quarter Y Balance Test is predictive of injury among volleyball players
131 young girls and boys (age 15.78±1.63, BMI 21.74±1.63) from provenance Premier League participated in this prospective study. The dynamic balance of players were measured by lower and upper quarter Y balance test in both side of their bodies before start of season. Then everyone was followed up for six months so that players' injuries and exercising hours and their races were recorded to the perspective way.
The results of cox regression test showed there is not significant relationship between overall score of Y testing in lower limb and injuries incidence rate for volleyball players (P>0.05, Hazard Ratio =0.36, %95 confident interval 0.07-1.07) but there is significant relation between overall score of Y upper body testing and injuries incidence rate for volleyball players, this means that decrease a score in this test is increasing incidence rate of injuries 6 times more (P>0.05, Hazard Ratio=0.06 %95 confident interval 0.01-0.36)
Results show that upper quarter Y balance test has worked out well and introduced as an acceptable test in this case. However, lower quarter Y balance test was not presented as an acceptable test in the field of predicting for volleyball players lower limb injuries. According to the results in this study, it is counselled that the medical and technical staff in the volleyball teams used dynamic balance measurement test, for instance, upper quarter Y test to know players at risk and to plan a preventive program based on the results.
