Introduction. High physical activity contributes to the growth of fitness and the strengthening of a number of physical characteristics [1]. Regular muscular activity associated with limb movements intensifies all types of metabolism, blood circulation, respiration and the functional capabilities of the nervous system.
The purpose of the study is to assess the level of physical development of students studying at the university and training in the sports walking section.
Methodology and organization of the study. The experiment involved 32 1st year students (aged 17-18 years) who regularly trained in the sports walking section three or four times during the week for at least an hour. They were divided into three groups, taking into account the amount of sports experience: one of them included those who trained for up to a year (12 boys); the second group included those who trained for one to two years (10 boys), and the third group included those who trained for more than two years (10 boys). The values of indices characterizing the functional status of students were recorded.
The results of the study and their discussion. As the length of the walking experience increased, an increase in the Pinier index was noted, indicating a strengthening of the existing somatic status. The value of the Erisman index in the sports walkers of the second and third groups was higher than that in the first group, respectively, by 24.6% and 58.4%.
The value of the body mass index of the boys in the first group turned out to be 18.4±0.49 kg/m2, in the second group – 18.7 ± 0.34 kg/m2, in the third group – 19.1± 0.31 kg/m2, showing no differences in this parameter among those with different walking experience.
The value of the Rohrer index in the first group (13.7±0.32 kg/ m3) turned out to be slightly higher than in the other groups, proving a slightly less harmonious physique, compared with the boys of the second group (11.7±0.29 kg/m3) and with the boys of the third group (10.5±0.34 kg/m3).
The values of the Pirke-Beduzi index in the observed groups showed no significant differences: in the boys of the first group it was 90.5±0.65%, in the second sample it was 92.7±0.61% and in the third observed group 93.6±0.57%. In the case of an increase in the length of athletic walking, the value of the life index increased. In the second group of boys, it was 12.4% higher than in the first group, and in the third group, it prevailed over this index in the first group of trainees by 16.5%.
The value of the Kaznacheev index increased as the length of training experience increased. In the boys of the first group, it turned out to be 0.6 ± 0.07%, in the second group – 0.8 ± 0.04%, and in the third group – 0.9± 0.08%.
Conclusion. As the length of training in athletic walking increases, a number of positive morphofunctional changes develop in the youthful body. Under the conditions of these trainings, the frequency of occurrence of medium and large body types increases among students, as well as the harmony of the physique and general physical capabilities increase.
