The following article focuses on ilustrating the content of the master thesis with the same title. The methodology of developed by author digital indicator will be presented, as well as the results and conclusions based on the comparative analysis. The research concerns the comparative analysis between digital services in Poland, Japan and China, based on the IDI, WDC and ITC digital indicators. The analysis is based on publicly available data of digitization.

Symmetry of support scull and vertical position stability in synchronized swimming

Maintaining the body underwater in the so-called vertical position, where the body is inverted (head down) and balanced, is made possible by performing the support scull movement by the upper limbs. In synchronized swimming, the main criteria for judging this vertical position are maintaining body stability and the maximum height of the lower limbs one is able to extend out of the water. Therefore, it seems important to examine for any correlations between the symmetry of the upper limb’s movement (sculling) and the ability to maintain balance of the body. The aim of this study was to use a dynamical asymmetry index (DAI) to assess the symmetry of the upper limb movements performed in synchronized swimming. The use of the dynamical asymmetry index is considered to be advantageous over the asymmetry coefficient, which is better known in literature on the subject and has been used by numerous authors, as it not only evaluates the magnitude of the asymmetry, but also indicates in which phases of movement asymmetry is the greatest or where it is the least significant.
