  ABSTRACT: In this study, we sought to reveal and evaluate the degree of similarity between individuals and within the same group of individuals when they perform the same movement. The methodology used was that of selecting a panel of participants, 38 normal healthy adults ranging in age from 10 to 30 years. Subsequently, we carried out the experiment by performing the movements while capturing videos using a smartphone. The two-dimensional coordinatesof each joint were obtained for videos obtained using marker less motion capture software. The results obtained allowed for a cluster analysis using five time series variables: 1) vertical head movement and 2) lateral limbmovement. These time series were normalized by a total time, in order to createa typology of jumping movements. 136 series of movies were obtained. After checking the movies, 115 series revealed errors such as misrecognition. Theseseries were excluded from the analysis. The remaining 21 series had data availablefor analysis. Cluster analysis was performed on the 21 sets of motion data, which could be classified into seven clusters based on the shape of the dendrogram.
