HUMAN BODY MODELLING INVESTIGATION OF ROWERS
AbstractThe aim of this study was to investigate of the main factors of the rowing performance. This is what was measured and investigated by kinematic analysis and body modelling. The previous comparative experiences shown that there are significant differences concerning to the body proportions of athletes especial1y between the different kind of the paddlers and rowers. Using the Hanavan's mathematical body model and the Clauser's regression equations to estimate the mass values of the segments the human body model in respects of the mass of its parts reflects the real specialization in different kind of sports. The percentage values of the tight's mass of rowers are hi her than the tight-mass of other paddlers of canoe and kayak. The examined sample were the members of the national elite teams of man of each sport branches. The higher tight-mass percentage is appeared in the case of the younger elite man-rower team. The higher value of the tight-mass covers a larger muscle mass value in the case of the very well trained athletes. In the laboratory experimental surroundings rowing on the Specialized rowing ergometer beside the growing load ( step by step). We investigated the kinemtical parameters of leg-work by SELSPOT motion-analyzer system. We compared the stretching of the leg and the distances of the movement of the seat by time. There were five levels of the growing loads. The results of the experiences show the mistakes of movement pattern by growing load because of the tiredness. The movement under growing loads simulates the competition of 2000 meter distance. The duration of the test was nearly 15 minutes. The technical weakness were appeared in the exerted conditions. These investigations can help for the rowers to correct the movements and to be improve of their economical techniques.
