Materials and Methods: The research involved 246 cadets (men) of the 1st-4th training years, who were majoring in the specialty 253 referred to as “Military Management” (specialization “Management of Tank Troops”). The research was conducted in 2022-2023 during field training exercises lasting 2 and 4 weeks. Research methods: theoretical analysis and synthesis of literature, medical and biological methods, testing, statistical analysis. Results: It was found that the level of health and physical development of cadets deteriorates during their field training exercises. The worst level among the studied indicators after the cadets’ field training exercises was recorded in the indicators of vital index, Robinson index, and endurance level. It was found that the longer the duration of field training exercises, the more the health and physical development of cadets deteriorates. The most pronounced deterioration in the level of the studied indicators was found in the cadets of junior training years. Conclusions: The deterioration of cadets’ health and physical development during their field training exercises has been proven. The most negative changes occurred in the indicators of the cadets’ cardiorespiratory system. The results indicate the need to improve the organization and methods of physical training with cadets during field training exercises, which will help maintain their health and physical development at the proper level.
