Abstract

96 first-year students of the Astrakhan State University of Architecture and Civil Engineering and the Astrakhan State Technical University, boys aged 17-18 years old, took part in the study on a voluntary basis.In the first group (students were engaged in an experimental program of a health-improving nature), at the start of the study, significant differences were shown in lower results of right-hand dynamometry (p<0.05). In the second group (students were engaged in a standard program of physical education), the studied indicators significantly exceeded such indicators in the main group according to the Genche`s test and the pulse

recovery time after exercise (p<0.05).A high percentage of boys of the first group with a weak pulse recovery reaction was found (42.9%), in the second group, a bad reaction was determined in 28.6% of boys.In the first group, when using a health-improving technique in physical education classes and after two courses of using trekrezan (in autumn and spring) at the end of the study, i.e. at the end of the academic year, a significant improvement was registered in the indicators of the speed of pulse recovery after physical exertion (p<0.01). In the first group changes towards growth are noted in these indicators: by 6.1% for the Stange`s test and by 14.2% for the Genche`s test. In the first group, the results significantly improved for most indicators of the studied characteristics (p<0.01; 0.05), with the exception of static endurance of the back and arm muscles.They haven't changed. The maximum positive changes in this group were recorded at 18.6% in the study of dynamic endurance, at 10.2% of working capacity, and at 15.0% of power endurance.The indicators in the Juhash test increased by 21.0%. The comparison of intergroup differences showed significant changes of the first group of boys in the indicators of the step test (p<0.01). Most of the boys of the first group at the beginning of the study had a lower level of some qualities and functions that determine the adaptive capabilities of the human body.At the end of the study, positive dynamics was noted for most indicators in the first and second groups. Health-improving methods in practical physical education classes and the use of trekrezan are an effective means of strengthening health, preventing acute respiratory infections and increasing the adaptive potential of the body.
