Aim: To study the dynamics of students’ morphofunctional status indicators during their high-intensity interval training (HIIT). Materials and Methods: The research involved 132 male students divided into three groups: students in Group No. 1 (n = 27) did HIIT; Group No. 2 (n = 69) – various sports (sports games, martial arts, strength sports, athletics, swimming, cycling); Group No. 3 (n = 36) – general physical training. The morphofunctional status was assessed using indicators of height, body weight, lung vital capacity, hand dynamometry, heart rate, and blood pressure. The generalized indicator of students’ morphofunctional status was assessed using the methodology developed by Ye. A. Pyrohova. Results: It has been proven that HIIT effectively improves students’ morphofunctional status during their studies. Most of the morphological and functional indicators of students who practiced HIIT were significantly (p . 0.05-0.001) better in the 3rd and 4th instructional years than those of students who practiced general physical training. The most significant effect of HIIT was an improvement in indicators of body weight and in the functioning of students’ cardiovascular and respiratory systems. Compared to Group No. 2, the indicators of Group No. 1 do not have significant differences (p > 0.05). Conclusions: The results obtained allow us to assert the effectiveness of HIIT, as well as any kind of sport, during their studies at higher educational institutions under martial law, to increase students’ motor activity, improve their morphofunctional status, physical and mental performance, strengthen their somatic and mental health, and promote harmonious personal development.
