Abstract

Background: Jump and landing is the characteristics of most sports and one of the main mechanisms of anteriorcruciate ligament injuries. Researchers believed mechanism-based designing the preventive exercises can possiblyhave a better effectiveness. The aim of this study was to evaluate the effect of eight weeks of jump-landing exerciseon feedforward and feedback activation of selected trunk and lower extremity muscles and performance in activefemales. Methods: In this quasi-experimental study, 25 active females age ranged 18-26 years were participated. Theelectromyography device ME6000 model and triple hop test were used for muscle activity (hamstring, quadriceps, gluteus medious and maximous in drop landing) and performance evaluation respectively. After pre test, theexperimental group underwent to Herrington et al eight weeks of jump-landing exercises. After implementation oftraining, post test of ELECTROMYOGRAPHY and performance were done similar to pre test and data were statisticallyanalysed by using independent and sample t tests. Results: Results of paired t test revealed that the jump-landing exercises led to significant differences infeedforward and feedback activation [VM(Pff=0/002, Pfb=0. 001), VL(Pff=0. 001, Pfb=0. 021), RF(Pff=0. 004, Pfb=0. 001), MH(Pff=0. 001, Pfb=0. 001), LH(Pff=0. 001, Pfb=0. 034), Gmed(Pff=0. 001, Pfb=0. 001) and Gmax(Pff=0. 001, Pfb=0. 001)] and performance(P=0. 001) in experimental group from pre test to post test whereas there was nosignificant differences in control group. Conclusion: It can be concluded that jump-landing exercises with modifying and optimizing the knee stabilizeractivation and in other hand with improving the performance might have important role in ANTERIOR CRUCIATE LIGAMENTinjury in active females.
