The functional state of the circulatory system is central to adaptation to physical exercise. Assessment limited to resting parameters or the immediate muscular response does not reflect the complete hemodynamic response, particularly rapid recovery. Different types of exercise and training stimuli involve central, peripheral, and autonomic regulatory mechanisms to varying degrees. Aim – to substantiate a conceptual approach and develop a methodological framework for studying reactive and adaptive circulatory changes according to exercise type and training stimulus, based on the assessment of central hemodynamics and autonomic regulation. This methodological study will involve young adult men divided into groups of untrained individuals, individuals engaged in conventional resistance training, and those engaged in functional TRX training. The model includes assessment of stroke volume, cardiac output, cardiac index, total peripheral vascular resistance, and heart rate variability before and after dynamic, static, static-dynamic, and high-intensity interval exercise, with repeat assessment after one year. A six-block protocol was developed, comprising baseline morphofunctional assessment, standardized exercise tests, evaluation of reactive changes and rapid recovery, control of experimental conditions, and longitudinal assessment of adaptation. Simultaneous analysis of circulatory effector parameters and autonomic regulatory mechanisms was substantiated. Quantitative results are not presented because the study is at the implementation stage. The developed model provides a methodological basis for comprehensive investigation of circulatory reactivity and long-term adaptation to different types of physical exercise. Its implementation will help identify specific hemodynamic and autonomic adaptations and assess rapid recovery as an informative marker of functional reserves.
