Abstract

Chronic obstructive pulmonary disease is characterized by pronounced clinical and biological heterogeneity. It determines a wide range of responses to therapeutic interventions, including pulmonary rehabilitation. Exercise training remains the primary non-pharmacological strategy capable of improving exercise tolerance, symptoms, and quality of life; however, individual responses to rehabilitation programs vary considerably. In recent years, there has been a rising interest in the use of biomarkers that reflect inflammatory, metabolic, and microbiome-related changes induced by physical activity, with the aim of advancing personalized rehabilitation approaches. This review summarizes current evidence on biomarkers of systemic inflammation, oxidative stress, and DNA damage, as well as alterations in gut and oral microbiota in patients with chronic obstructive pulmonary disease undergoing rehabilitation. It has been shown that the changes in the content of interleukin-6, C-reactive protein, 8-isoprostane, malondialdehyde, phosphorylated H2AX histone proteins, 8-OH-deoxyguanosine, and the profile of short-chain fatty acids may reflect the pattern of physiological adaptation to exercise and serve as objective indicators for the optimization of training programs. Particular attention is given to the role of omics technologies and the emerging field of rehabilomics, which enable integration of molecular data with clinical outcomes to develop individualized rehabilitation strategies. Despite the promise of these approaches, their implementation in clinical practice remains limited by insufficient methodological standardization and data heterogeneity. The need for large-scale longitudinal studies with unified protocols is emphasized. In the future, the integration of biomarkers and multi-omics approaches may enable the development of more precise, adaptive, and effective rehabilitation programs aimed at improving functional status and quality of life in patients with chronic obstructive pulmonary disease.
