Aim: To investigate the prevalence of healthy lifestyle skills and physical health indicators among future law enforcement officers during their professional training under martial law. Materials and Methods: Conducted between 2025 and 2026, this research involved 171 male cadets enrolled in the first (n = 59), second (n = 57), and third (n = 55) academic years. Subjective health indicators were assessed based on the level of health-promoting skills development using the “Health-Promoting Lifestyle Profile, Adult Version” questionnaire. In contrast, objective health indicators were determined via Professor G. L. Apanasenko’s rapid assessment method. Results: It was found that the overall level of health-promoting skills development among cadets is average. Statistically significant differences were found in the development of healthy lifestyle skills between third- and junior-year cadets (p ≤ 0.05). The application of the rapid method for determining somatic health levels in cadets confirmed the consistency between survey data and objective indicators. The increase in the level of health-promoting skills development among senior-year cadets is accompanied by improvements in somatic health indicators, indicating a correlation between subjective and objective characteristics. Conclusions: An average level of healthy lifestyle skills development was observed among cadets, with significant improvements in indicators during the academic training process. A positive trend in cadets’ physical health was observed, indicating improved functional capabilities and suggesting directions for optimizing the professional training system for future law enforcement officers
