In the article, the analysis is made for throw by the undercut in the knee (Hiza-Guruma). The aim of the study was to establish the physical basis of the throw. For the analysis, the classification of throws, previously proposed by the authors, was used. According to this classification, the shots were divided into four groups: a pair of forces, a lever, a block and a combined group. For the study, video recordings were used, located on the Internet on the video hosting You Tube. As a result of the work carried out, it was established that the throw Hiza-Guruma can be performed by means of a lever or by a combination of a lever and a block. The data obtained can be used to build the training process in the Youth Sports School, teenagers and youth clubs with older students, and also in the process of physical education at higher educational institutions.
