Functional training as an effective way for adaptation of the military students and students of educational institutions in the system of the Ministry of Internal Affairs of the Russian Federation

Aim. The aim of this article is to study the functional state of military students and students of the educational institutions in the system of the Ministry of Internal Affairs. Materials and methods. CrossFit is a multifunctional training of high intensity. The peculiarity of this type of movement activity is that all trainings are conducted according to the pattern with understandable and clear structure. The pattern is based on 3 trainings per week to provide a relatively large amount of high-intensity load within 20 minutes during each training. Each training consists of 3 different elements: metabolic exercises, gymnastics and load exercises. This pattern provides the possibility to acquire new elements and to train effectively 3 energy systems. To estimate the effectiveness of this method, we conducted a pedagogical experiment at the premises of the East-Siberian Institute of the Ministry of Internal Affairs of the Russian Federation. Results. The results obtained allowed us to establish that introduction of CrossFit exercises in the experimental group improved the speed of adaptation processes and effect on functional state of the body in comparison with the control group, which demonstrated decreased functional capacities of the body and unsatisfactory adaptation. Conclusion. The results obtained for the study of the cardiovascular system after the introduction of high-intensity multifunctional exercises CrossFit in the experimental group revealed changes in variation pulsometry reflecting increased effect of the parasympathetic system on heart regulation. There is also an increase in М0 and R-R with a decrease in AМ0, SI and PV. The abovementioned allows us to suppose that the dynamic monitoring of the heart rate provides us with the possibility to perform effective control and to estimate the effect of physical exercises on the body.
