Aim: To investigate the investigate the impact of various types of motor activity training sessions on the mental and physical health of cadets during their wartime training. Materials and Methods: The research, conducted during 2023-2024, involved 203 cadets from the 1st to 4th training years (male). There were five groups of cadets engaged in various sports and motor activities. Research methods included bibliosemantic, psycho-diagnostic, medical and biological, and mathematical statistics methods. Results: In the groups of cadets who systematically practiced the chosen sport during training (groups 1-4), mental and physical health indicators at the end of the research were better than in the cadets who practiced according to the current method of motor activity (group 5). The levels of stress resilience, nervous and emotional tension, reactive anxiety, emotional state, body mass index, vital index, strength index, and Robinson’s index were significantly (p . 0.05-0.001) better in groups 1-4 compared to group 5. Instead, no significant difference was found between the indicators of groups 1-4 (p > 0.05). The most important effect of different types of motor activity was found in the indicators of the emotional state, cardiovascular and respiratory systems of cadets. Conclusions: This suggests that conscious training in any motor activity is effective in reducing stress, nervous tension, and anxiety, while restoring emotional balance and improving physical health indicators in cadets during wartime training.
