Gymnastic Movements with Strain of Parallel Bars

Abstract

Gymnasts have to use a special movement pattern for particular long swing movements to gain elasti parallel bars to complete long swing movements artistically and therefore needs to study not onl dynamics but also the dynamic properties of exercise apparatus to minimize the execution errors. In o mass 50.4 kg national level gymnast of China performed three repetitions of a long swing element under bars. The time history of middle points of wooden bars and all joint angles were measured by using sy high speed cameras (100 Hz). The ViconT40 digitizing software was sued to find the all coordinates o markers (14mm) which were attached on parallel bar-gymnast system. Based on the overall readings, we a 3D mathematical model for the parallel bars apparatus using four damped spring-mass model displacement-force characteristics. This 3D model can demonstrate dynamic properties of parallel bars with any long swing movements for any gymnast. 2. Introduction and research problem/issue Gymnastic movements which start with long swing under the parallel bars are highly difficult compared with other movements of parallel bars apparatus because of the verity of evaluations w introduced by FIG based on long swing movements (Code of Point MAG, 2017). Therefore, gymna utilise strain of the parallel bars in the correct manner. For this aspect, gymnasts have to use a special pattern for particular long swing movements to gain elastic energy of parallel bars to complete movements artistically. The gymnast essentially needs to study not only the body dynamic but also th properties of exercise equipment/apparatus which interact with their movement to minimize the execu (Yamasaki, Yasuhiro & Gotoh, 2008).

problem, biomechanical models can provide important results which are based on performance (Hiley 2005). A 2D frontal plane modal for the parallel bars apparatus was developed assuming that th movements of the tops of the metal posts are negligible (Linge S, Hallingstad O & Solgerg, 2006). W that the tops of the metal posts were interacting with long swing movements. Therefore, we designed a bars model to observe the correct dynamic properties of parallel bars which are engaged in long swing m
