Aim: To determine the impact of adaptive volleyball training sessions on the psycho-emotional and functional state of combatants. Materials and Methods: The research involved 64 service members participating in combat operations who underwent rehabilitation in 2024-2025 after injuries and damages to the musculoskeletal system. The duration of the research was 6 weeks. The research employed theoretical, empirical, and mathematical statistical methods. Results: It has been found that adaptive volleyball training sessions have a positive effect on the indicators of psycho-emotional and functional state of combatants. A significant improvement in the indicators of emotional state (p . 0.001) by 1.33 points and neuro-emotional stress (p . 0.05) by 4.43 points has been found. The functional state of the respiratory system in combatants also improved by 5.6 seconds in the Stange test and by 2.9 seconds in the Genchi test. The indicators of the functional state of the cardiovascular system in combatants, according to the Rufier Index, have also improved by 0.83 c. u. after the use of adaptive volleyball training sessions. Still, the changes were not significant (p > 0.05) due to the short period of the research. Conclusions: It has been established that adaptive volleyball is an effective means in the framework of physical education and sports rehabilitation for individuals who have suffered musculoskeletal injuries. It has been proven that adaptive volleyball training sessions have a positive effect on the indicators of the psycho-emotional and functional state of combatants.
