Martine-Kushelevsky test and evaluation of the functional state of the cardiovascular system of KRSU students

Physical fitness is most often considered as the fitness of two systems that work together: the cardiovascular and respiratory systems. Furthermore, physical fitness refers to the ability of these systems to maintain normal body function during physical activity of varying duration and intensity. There are various self-monitoring methods, one of which is the Martine-Kushelevsky test. This article presents the results of assessing the functional state of the cardiovascular system based on the Martine-Kushelevsky test. This test provides objective data on the cardiovascular system's functional state in students. The data helps to evaluate the body's resistance to hypercapnia and hypoxia, which reflects the overall condition of the body's oxygen-supplying systems during physical exercise. The study involved 187 first-year students from the medical faculty of KRSU, including 115 females (61.5%) and 72 males (38.5%). The age of the participants ranged from 17 to 21 years, with an average age of 18.29±1.05 years. One of the key indicators of the functional state of the cardiovascular system is the Robinson index, which characterizes the systolic work of the heart and reflects the degree of adaptation of the body to physical loads. Generally, it is believed that the higher this indicator, the greater the functional capacity of the heart muscles. The analysis showed that most students (87.7%) have a very low level of physical recovery, and 37.5% of students have poor aerobic capacity. These two factors should be taken into account when assigning students from the medical faculty to physical education groups.
