Most of the previous researches focused on kinetic analysis of these activities rather than kinematic analysis. Also, there is a lack of comparative studies that were performed between the two types of activities. The main aim of this study is to perform lower extremity kinematic analysis to find the kinematic differences between si <a name="_GoBack"> </a>ngle and double-leg jump (DL) landings in the sagittal plane (SP),in male handball players. The lower extremity kinematics were measured in 15elite male handball players(while performing SL and DL landings), by using three-dimensional motion analysis system (VICON). The results revealed statistically significant difference between the lower limb kinematics of SP SL and SP DL . During the SP DL, the hip and knee flexion angles increased more than those in SP SL , while there was more knee adduction with internal rotation stress in SP SL than in SP DL ( P < .05). The hip and knee flexion angles in the SP DL showed moderate association with those during the SP SL ( R 2 , 0.49 and 0.44 respectively). In addition, the hip abduction in the SP DL showed moderate association with those during the SP SL ( R 2 , 0.37). But, hip internal rotation, knee adduction, and knee internal rotation in the SP DL showed weak association with those during the SP SL (R 2 = 0.02-0.041; P ˃ .05). The double-leg jump landing maybe considered as a less stressful task for the lower limb joints than the single-leg jump landing activity. As a clinical benefit, the double-leg jump landing activity may be used to screen the ACL injury risk in certain planes of joint motion. <o:p> </o:p> }, number={3}, publisher={Selcuk University}
