Purpose of the study – to develop and present a systemic model of athlete functioning as a basis for digital management of the training process in road cycling; to formulate criteria of minimal sufficiency for the core set of training load indicators and, on this basis, to substantiate the selection of the G–t–v triad for the «plan–fact–decision» control loop (a detailed justification is presented in [2]).
Methods: The study employed systems analysis and structural-functional modeling of the managed object («athlete»), theoretical analysis of regulatory and methodological approaches to prescribing and controlling training load, and generalization of practical experience in scientific and methodological support of the preparation of sports reserve athletes (PSSR), where sports reserve refers to athletes within the regional talent-development system forming future regional and national teams. As observable characteristics of physical work, the indicators t (time), v (speed), and G (gradient/terrain difficulty) were used, forming a three-parameter representation of training load in the G–t–v format.
Results: A systemic model of athlete functioning as an object of digital management (inputs, states, outputs, and constraints) was proposed. It was shown that G–t–v constitutes a minimally sufficient core for digital control and «plan–fact» comparison in road cycling: t and v ensure observability, while inclusion of G eliminates the methodological incompleteness of a two-parameter (t–v) description in a terrain-based discipline and improves the correctness of managerial interpretation. A control loop was specified: planning → fact registration → plan–fact comparison → assessment of deviation criticality → managerial decision → registration of the coach’s managerial action → execution control. This loop transforms control and data registration from a «collection–storage» mode into a reproducible cycle of preparation and implementation of managerial action. After training (n=12), preparation of an individual physical training program (IPTP) for a given athlete profile required a median time of 2-3 minutes.
Conclusion: The proposed model and control loop, based on the G–t–v core, are applicable to the development of automated monitoring systems and to improving the scientific and methodological support of PSSR under conditions of limited measurement infrastructure, ensuring standardized «plan–fact» comparison and assessment of deviation criticality without reducing the quality of managerial decisions.
