Factorial Analysis of Body Elements in Rhythmic Gymnastics

The main goal of this research was to analyze body movements of rhythmic gymnastics techniques, groups A and B, to classify them into homogeneous groups, to determine similarities between the obtained groups. The sample of entities was comprised of 108 body movements (elements), pertaining to the difficulty groups A and B, that were described by 33 variables. Reliability of the measuring instrument was determined on the basis of obtained opinions, collected from eight experts in rhythmic gymnastics. Ten significant latent dimensions were obtained by factor analysis under the component model with the Guttman-Kaiser criterion. The latent dimensions were interpreted as: one-leg jumps, spine mobility, frontal flexibility, free leg movements, the help of the arm-work, body rotation, two-leg jumps, forward bend, other jumps and specific elements. It is feasible to state that the application of the sophisticated measuring instruments for the different anthropological factors and biomechanical parameters determination could have provided more information on the characteristics of and differences between the rhythmic gymnastics elements.
