Dosing students’ physical activity: A model of individualization based on psychophysical criteria

The study presents a practice-oriented model of physical activity dosing for mass physical education practice, designed to individualize the training process of students. The relevance of the research is determined by the necessity to take into account the level of physical fitness of students in conditions of limited pedagogical resources. The purpose of the work is to theoretically substantiate and structure the model based on three criteria: heart rate, subjective assessment of Borg scale fatigue, and baseline level of physical fitness. The research has shown that the use of this model contributes to the safe adaptation of students to physical exertion, improves the functional parameters of the body and reduces subjective feeling of fatigue. The model is suitable for use in the educational process of universities, in fitness programs and wellness practice. The need for its further empirical validation and integration into the normative and methodological support of physical education is noted.
