INFLUENCE OF "VELOPUMPING" TECHNIQUES ON RACER’S SPEED DURING NON-PEDALING PHASE IN BMX-RASING
In the article for the ﬁrst time in the aspect of theoretical mechanics considers the inﬂuence of the motor act «velopamping» to increase the speed of the cyclist in the discipline of BMX-racing in the absence of pedaling. The increase in the absence of a cyclist pedaling rate was due to a physical phenomenon - «parametric resonance» which arises as a result of the periodic variation of the system parameters: its moment of inertia and center of gravity when moving cyclist on the convex and concave surfaces.
