Algorithm Defining the Correctness of an Ergometer Rower’s Technique Using Three-Dimensional Data

The aim of the article is to present a model of the rower, taking into account the most important angles and the new algorithms for studying the position of the rower’s body at different phases of rowing. The positions of the rower’s back, elbows and wrists during rowing were analyzed. The paper presents research on the motion capture of rowers practicing on the Concept II Indoor Rower ergometer, using a motion capture system produced by Vicon. The data obtained with the motion capture system and the results generated with the proposed algorithm(s) allow to clearly identify the studied subjects’ degree of training and rowing technique on the basis of the analysis of changes in the inclination of the body parts in different phases of rowing.
