| Abstract | VASCONCELLOS, Roberta Pires. Vibration platform: magnitude and transmissibility of body structures of adults in different protocols. 2013. 112f. Dissertation (Graduate Program in Physical Education) – University of Santa Catarina, Florianópolis, 2013. The physical exercise on vibration platforms has been widespread, not only in the context of physical training geared to performance, but also aimed at promoting health and physical rehabilitation. However, there are still very few studies that have examined the magnitude and vibration transmissibility of body structures in individuals subjected to this type of training. Thus, the aim of this study was to analyze the characteristics of the vibrations transmitted to the body structures of adults at different conditions of exposure to whole body vibration (WBV) with vibration platform. Participated in this descriptive and correlational study, 20 subjects, 10 men and 10 women, with a mean age of 27.1 ± 3.8 and 28.5 ± 1.8 years, selected intentionally. Data were acquired with triaxial accelerometers fixed to the body of the subject on a vibration platform at the frequencies of 20, 35, 50 and 70Hz and displacement amplitudes of 2.0 and 6.0 mm, in two different positions: EP (extended knees and weight deposited on the rearfoot) and FP (knees bended and body weight on the forefoot). There were 16 sets of 30 seconds, totaling 8 minutes of exposure to whole body vibration. The execution order of record, considering body position on the platform, frequency and amplitude of vibration was randomized. Data were analyzed using descriptive and inferential statistics (p ≤ 0.05). Significant differences were identified: (a) the magnitude of the vibratory motion axes, being higher for the vertical axis between the points and body, being higher for the ankle, (b) the magnitude and vibration transmission through the body segments, with attenuation more expressive the passage in the trunk segment, (c) the magnitude and vibration transmissibility between body positions, with better transmissibility to FP, (d) the positioning and higher vibration amplitude are associated with a higher incidence of symptoms of pain and / or body discomfort, the most frequent headaches, backaches and nausea. From these findings, which provide concrete information regarding this type of training, it follows the VT should be applied to a higher frequency range (above 50Hz) and lower amplitudes, adopting a correct body position on the platform. In this sense, it is essential that this practice happens so always guided by trained and qualified professionals in order to avoid common mistakes, but harmful to health, are practiced. So, effectively and safely, the whole body vibration training with vibration platform can gain a more prominent space in the world of fitness and greatly enhance their integration into the labor market, with more and more followers and promoting increasingly benefits health, performance and quality of life. |
