THE PARALLEL BARS MOVEMENTS WITH STRAIN OF BARS

The long swing movements of a national level gymnast (50.4kg) were used to observe time history of joint angles of body and the middle points of the parallel bars in different conditions. Parallel bars were modelled using four massless spring dampers and two point masses. Further, a 50kg metal spear was attached to the middle points of the parallel bars and their oscillations on different planes were observed. Parameters were calculated using a parallel bars model and were compared with the standard specifications of the Federation of International Gymnastics (FIG). Hence, the dynamic forces which are acting on the middle points of the parallel bars for a long swing movement were calculated
