Purpose: to define the dynamics of physical development indicators among medical college students in 2017 and to compare it with the results of the previous study of 2005. Method: The inclusion criteria were: no health complaints at the time of the examination, no chronic diseases in family medical history, no deviations from the norm in clinical and laboratory tests. The selected young men were examined by medical specialists (neuropathologist, ophthalmologist, otolaryngologist, therapist, surgeon); detailed clinical, laboratory and diagnostic tests were conducted: X-ray; spirography; electrocardiography; dental examination; ultrasound examination (cardiovascular, thyroid, abdominal, urological); biochemical blood testing. The participants were subdivided into two groups: Group 1 (students (n=140) who studied at Zhytomyr Medical College in 2004-2005) and Group 2 (students (n=150) who studied at Zhytomyr Medical Institute in 2016-2017). Results: According to the results of studying the dynamics of anthropometric, functional and psychophysiological indicators of physical development among Ukrainian medical college students (n=290; 17-21 years old) in 2017, comparing them with the results of the previous study, conducted in 2005, the tendency to gain in body mass in average values from (0.88 ± 0.26) to (2.7 ± 0.67), in body mass index from (0.88 ± 0.26) to (1.38 ± 0.38), in the fat component from (8.70 ± 0.22) to (9.36 ± 0.21) was established. Conclusions: An increase in body mass index, the fat component in medical college students was revealed, which is related to problems in the quality of the students' diet. Though the muscle mass has increased, and the study indicates that there is insufficient physical activity; sustainability and concentration of attention indicators tend to decrease under the influence of intensification of the educational process. The dynamics of the indicators under analysis indicates the stabilization of the growth process in Ukrainian male students.

Aim: The aim is to scientifically substantiate the feasibility of using the health improving forces of nature to slow down the natural aging of people of different ages. Materials and Methods: The research involved 5 groups of respondents: the 1st group – students who were involved in sports (28 boys, 34 girls), the 2nd group – students who were not engaged in sports (29 boys, 22 girls), the 3rd group – female adults (45-65-year-old; n = 16), who were not engaged in health improvement training, the 4th group – female adults (45-65-year-old; n = 13), who used biologically active additives, the 5th group – 45-65-year-old women (n = 27) and men (n = 18) who were engaged in health improvement training according to the system by P. K. Ivanov. Results: It was found that the physiological age of the 1st group was higher than the stated age; of the 2nd group corresponded to the stated age; of the 3rd group was exceeded the stated age by 6.9 years; of the 4th group was exceeded by 5.8 years; of the 5th group was lower than the stated age by 4.8 years for men and by 10.1 years for women. Conclusions: It is proved that tempering according to the system by P. K. Ivanov, which does not require any material costs, has a pronounced health effect on the body of people of different ages (especially mature and elderly).
