RASQUINHA, Edward; KELENCZ, Carlos Alberto and MAGINI, Marcio. Study of the physical components implied with the angle of landing in the rolling movement executed at the floor apparatus in artistic gymnastic. Rev Bras Med Esporte [online]. 2006, vol.12, n.4, pp. 184-188. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922006000400004.
INTRODUCTION: Biomechanics is a sub-area of physics responsible for the study of the human movement. The artistic gymnastics is a sport modality that intrigues the researchers, in this context; this work comes to analyze one of the movements most important of this modality, the rolling. SCOPE: To analyze the implied physical components with the execution of the movement of the rolling, looking for to establish some relation between these and the angle of landing measured to the end of this acrobatic element. METHODS: The sample was composed for seven gymnasts, with age varying between 14 and 20 years, with a time of training of at the very least five years. This research was used of tools based on principles of the classic mechanics, techniques of photogrammetry and statistical treatments. RESULTS: From the implied physics related with the execution of the rolling, the external torque presented greater relevance. The results were obtained from analysis of groups with distinct levels of experience. The variability of the experimental data was statically treated providing a set of conclusions relevant to this study. CONCLUSIONS: The results showed the relation between the values of angle and external torque. The increase of the torque was related with low values of the angle. It was verified the influence of the torque by the initial acceleration, according with preliminary works.
