CLASSIFICATIONS OF TECHNICAL MEANS OF PHYSICAL TRAINING AND ASSESSMENT OF THEIR EFFECTIVENESS BASED ON BIOMECHANICAL PRINCIPLES OF STRUCTURING MOTOR ACTIONS by M. B. Sotsky

“…As a result, digital indexing of the above targets was proposed which allows to group and present the technical means in the form of matrix depending on the combination of the indexes and to determine promising trends in novel developments finding the blank areas in the matrixIn accordance with the proposed classification by the example of technical means of strength training, the concept of the biomechanical efficiency of the devices is introduced for the first time, for which specific numerical coefficients were introduced such as spatiality, inertia and energy dissipation.The paper presents a qualitative analysis of the typical means of strength training in terms of biomechanical efficiency, which showed the prospect of engineering technical devices with many degrees of freedom using the friction method of creating the resistance when training.…”
