Experimental substantiation of the use of intelligent sensor systems in the assessment of biomechanical parameters of sport movements

The paper describes the design and software features of an intelligent sensor mounted on the oar shaft to register dynamic parameters characterizing the athlete’s interaction with the oar and the surface of the water in the supporting (water) part of the stroke. As a result of the study, experimental data were obtained, an algorithm was developed to analyze the strain-load curve and calculate the components of the resulting force applied to the oar during rowing. Based on a review of the literature corresponding to the research problem, as well as the data obtained during the pilot experiment, the prospects of using intelligent sensor systems as a means of quantitative description of the performance of sports movements in natural conditions are proved. The presented mathematical algorithm for calculating the values of the individual components of the resulting effort allows us to evaluate the ratio of the efforts made by the athlete and the resulting load on the paddle blades. The results allow us to conclude that the use of the method of mobile wireless tensometry for assessing the biomechanical parameters of sports movements is promising. Ways of further improvement of the developed methodology are determined.
