Aim: To investigate the impact of motor activity volume on the physical working capacity and somatic health of higher education applicants. Materials and Methods: The research included male cadets from the National Academy of Internal Affairs who were admitted in 2025 (n = 240). The participants were divided into two groups: SG 1 (n = 108) – cadets who regularly engaged in additional sports activities – and SG 2 (n = 132) – cadets who limited themselves to mandatory physical training sessions only. Methods: theoretical, empirical, and mathematical statistics. The Framingham method was used to assess motor activity and daily energy expenditure. The level of physical working capacity was assessed using the Harvard step test. The level of somatic health was determined using G. L. Apanasenko’s rapid assessment method. Results: It was found that cadets who engaged in additional sports activities had significantly (p < 0.05-0.001) better indicators of motor activity, physical working capacity, and somatic health compared to cadets who limited themselves to only mandatory physical training sessions: in SG 1, compared to SG 2, the motor activity index was 5.6 points higher, the Harvard step test index was 9.6 a. u. higher, and the somatic health level was 6.22 points higher. Conclusions: It was found that motor activity is an important factor in the development of physical working capacity and somatic health among higher education applicants, and that regular participation in sports contributes to increased body functional reserves, improved recovery after physical exertion, and enhanced adaptive capabilities.
