Knee pain and dysfunction have been often associated with an ineffective pull of the patella by the vastus medialis (VM) relative to the vastus lateralis (VL), particularly in individuals with knee joint malalignment. Such changes in muscular behavior may be attributed to muscle inhibition and/or atrophy that precedes the onset of symptoms. The aim of this study was to investigate possible effe...

41 To characterise rugby union lineout throwing technique, three experienced 42 male rugby players performed throwing trials under varying conditions of 43 distance and trajectory. Motion analysis permitted the recovery of joint centre 44 coordinates at 120 Hz and the construction of a three-dimensional linked 45 segment model for calculation of joint angle and centre of mass time histories. 46...

Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...

We have developed a 2-D analytical biomechanical model for monoarticular open kinetic-chain exercises with lever selectorized equipment, and different relative placement between the joint center of rotation (J) and the center of rotation (C) of the resistance input lever ("off-center" exercises). All the relevant geometrical aspects of such exercises have been characterized: the change with the...

Purpose: The purpose of this study is to examine the differences of kinetic and kinematic variables in middle-aged women with genu varum and normal knee angle during walking and running. Methods: Eight middle-aged women with genu varum (age: 45.12 ±12.74 y, height: 160.62 ± 5.26 cm, weight: 71.75 ± 16.38 kg, right tibiofemoral angle: -4 ± 3.9, left tibiofemoral angle: -5.1 ± 4.6) and 7 wi...
