Development and justification of adapted standards for cross-country testing in a gym based on experimental data and mathematical modeling

The paper is devoted to the topical problem of conducting control tests for cross-country training in a gym, which is due to the climatic characteristics of various regions of Russia. Specific features of indoor running are analyzed, including geometric limitations of the trajectory, the need for frequent turns, psychological aspects and biomechanical changes in the structure of the running step. The paper substantiates the need to adapt existing standards of cross-country training for gym conditions. A mathematical model for calculating the equivalent distance, taking into account the “corner cutting” effect when running around the perimeter of a basketball court, is presented. Experimental data obtained from a group of 20 test subjects confirm the theoretical propositions and demonstrate the need to develop special adapted standards to ensure the objectivity of pedagogical control in a confined space.
