| dc.description.abstract | The aim of this study was to compare the intracyclic variation of kinematical variables from the hip and the center of mass (CM) with the purpose to assess if the analysis of kinematical variables of the hip might replace the study of the kinematical variables of the CM. Seven Portuguese male swimmers of national and intemational levei were studied. Each swimmer performed 3 sets of3x25 meters, at a constant velocity and as close as possible to the maximum, using exclusively frontal inspiration cycles, lateral inspiration cycles and non-inspiratory cycles in each set. Two pairs of cameras were used to create "dual media" images. Another cam era was set behind an underwater window in the endwall. One last camera was placed above the water surface. The study comprised the analysis of complete stroke cycles in buttert1y using the "Ariel Performance Analysis System" from Ariel Dynamics Inc. Some of the correlations between the maximal vertical amplitude of displacement of the hip and the CM didn't present significant values. AlI the correlations between the horizontal velocity and horizontal acceleration of the hip and the CM were significant in all breathing models. However, only one swimmer presented in both cases r>=O.95. So, apparently, the hip does not represent properly the intracyclic variations ofthe kinematical variables ofthe CM. | pt_PT |
