ABSTRACT
Aim:
The aim is to investigate the effect of high-intensity interval training (HIIT) based on the CrossFit system on the level of students’ functional state and physical development.

Material and methods:
The research involved 36 male students who were engaged in HIIT during their studies. Indicators of students’ functional state and physical development after 1 and 3 years of HIIT were studied. The functional state was assessed by indicators of the cardiovascular and respiratory systems, and physical development – by physical education tests.

Results:
It has been found that HIIT has a positive effect on the indicators of the functional state of the cardiovascular and respiratory systems of the body and the physical development of students. After three years of HIIT sessions, students significantly improved their heart rate, vital capacity of the lungs, Stange test, Genchi test, duration of recovery heart rate, as well as the level of development of speed qualities, strength qualities, endurance and flexibility.

Conclusions:
It has been established that the sports-oriented form of organization of physical education training sessions with the use of HIIT based on the CrossFit system is quite effective in improving the indicators of the functional state and physical development of students. A high level of these indicators will help to improve students’ health, improve their well-being, and increase the effectiveness of their educational and, in the future, professional activities.
