Inverse Dynamics Analysis and Biomechanical Software for Lower Extremity of Sprint Runner Zahrasadat Mousavi z mousavi@me iut ac ir Date of Submission 20 12 2009 College of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiAbbas Fattah Fattah@cc iut ac irAbstractBiomechanical analysis has major role in rehabilitation sports and researches Biomechanical analysis softwaredoes not exist in our country because current software is too expensive at least sixty million tomans to be used inuniversities and research companies especially Olympic Academy To this end the inverse dynamics analysis andbiomechanical software is investigated in this thesis Here the whole body model is considered as 12 links includinghead neck right upper arm left upper arm right forearm hand left forearm hand trunk left thigh rightthigh left leg right leg left foot and right foot The joints are distal and proximal of each link coincidence toWinter antropometric data The x and y coordinates of the joints are considered as degrees of freedom TheNewton Euler method is used to derive equations of motion Also the moment at the toe of the stance leg issupposed to be zero in inverse dynamics analysis In order to validate our code the following test is performed Asprint runner runs and two cameras 250 HZ record his motion The passive marker is installed on the distal andproximal of each link and on the right and left heel and toe A force plate exists in the path of his motion The resultsof our code is in good agreement with the force plate data with a range of 20 error Why are some sprint runners running fast This is an important question for many coaches Thus in this project some of the kinematic and dynamics parameters such as contact time flight time length stride and angles of lowerextremity as well as forces and moments of the lower extremity are investigated for the elite and beginner sprintrunners Therefore two groups of sprint runners with the following properties are tested Elite group includes twosoccer players and two 800m sprint runner with the weight of 71 83 5 kg tall 178 7cm and age of 24 3 Beginnergroup includes one 400m sprint asian athlet two young 100m sprint record and one 60m sprint record inside byweight of 71 83 5 kg tall 178 7cm and age of 24 3 Two cameras made by KODAK by 36 3m distance fromeach other 35m and 38 36 from start point and 5 5m from the edge of the path Kinematics data is derived byWinanalyzed made by Mikromak 1998 in sagital plane 2D Then some kinematics parameters and force andmoment of the lower extremity compared between two groups of sprint runners The following conclusions aredrawn as Contact time and flight time Elite sprint runner have shorter contact time and flight time Stride frequency
