The article is dedicated to the justification and practical implementation of a nature protection-based methodological approach to define the boundaries of the Lake Baikal protection zone and form proposals related to the harmonization of instruments of environmentally responsible development of the territory, which has the status of a World Heritage site as it contains 20% of the world’s fresh water supply. An analysis of the contemporary conditions of Lake Baikal and its surrounding landscapes show environmental degradation of the area. The most important aspects in solving the existing problem may be the construction of a science-based definition of the Lake Baikal water protection zone and compliance with the universal global values related to the requirements of ecological threat prevention. The main landscape-hydrological design principles for the water protection zone are studied in this article. A method for the functional water protection zoning of urban territories is also given. This has been implemented in Baikalsk town, which is located on the Baikal shore and is considered to be one of the most environmentally damaged territories. Proposals include recommendations on the harmonization of the landscape-hydrological principles of territory assessment and methods for target landscape planning; the setting of various restrictions within the boundaries of existing industrial and settlement zones; the creation of an overall system of environmental health monitoring for Lake Baikal and its protection zones; and for ensuring interactions with the public.

Background: Many methodological problems associated in a sports and fitness environment based on a differentiated approach remain beyond the interest of researchers and developers. The aim of the study was to differentiate physical education classes in school in terms of the individual body mass index of schoolchildren and experimentally prove the effectiveness of its implementation for the harmonious development of youth. Study participants: schoolchildren 15-17 years (n = 64). All the schoolchildren were divided into four groups using the method of body mass index (BMI). Interventions: Pedagogical research was carried out for 7 months at school. The study used tests "Ready for work and defense", BMI, body health indicator and cognitive rate. Main outcome measures. In schoolchildren from the groups (EG1 and EG2), differentiated by BMI for physical education classes, the results on physical qualities improved: endurance and dexterity (p < .05). In CG1, where there was no differentiation, during the experiment 3 schoolchildren with overweight added. Thanks to the experimental intervention in EG1, the schoolchildren kept their initial BMI normal. Separate education of schoolchildren has a positive effect on the cognitive abilities of schoolchildren: comparison of EG1 and CG1 (p < .01), comparison of EG2 and CG2 (p < .05). Findings. The study showed the effectiveness of the BMI in differentiating of youth into groups. If the differentiating physical education at school to indicators of BMI, it will significantly improve the performance of physical and cognitive abilities schoolchildren 15-17 years old and reduce obesity of youth.

Purpose: A significant volume of data on the level of physical activity and health of male students presents at the literature. Scientists use the International Physical Activity Questionnaire (IPAQ) to collect data. Scientists point to the need to use objective practical tests that complement the IPAQ data. The purpose of the research is to search for objective data on the level of physical activity of undergraduate male students receiving education in Russian Federation. Material: Participants – male students (n=205, age-19-20 years). The period of research is March-April 2019. Students were divided into groups: G-1 – students (n=127) who did not have proof of their physical activity in sports and fitness, G-2 – students (n=78) who had provided confirmation. The International Physical Activity Questionnaire (IPAQ) in its extended version assessing four domains of activity, which was supplemented with original questions regarding perceived physical fitness (high, moderate, low) and favorite physical activity in sports and fitness was used in research. Students' physical fitness profile testing is performed using Functional fitness assessment tests. The collected data were analysed using SPSS20. Physical fitness test results were compared by using Mann-Whitney U–test. Results: The IPAQ data indicate a significant (P<0.001) advantage of students (G-2) in total physical activity. Students (G-1) have a significant (P<0.01) advantage in the volume of physical activity at work. The volume of physical activity in sports and fitness is significantly higher (P<0.001) for students (G-2). Functional fitness tests showed a insufficient level of physical fitness of students (G-1 and G-2). The results indicate a significant (P<0.01) advantage of students (G-2) in physical profile. Conclusions: Russian male students have more total physical activity than male students from African countries, Turkey, Iran, and Ukraine, but have a significantly low total physical activity level than students from some European countries. The total physical activity volume of Russian university male students is slightly less than the recommended by experts (6000 minutes per week or more). The volume of validated physical activity in sports and fitness of Russian students is about 39 minutes per day. The level of physical fitness of Russian male students does not fully comply with the Functional fitness assessment tests targets. A large proportion of sports and fitness physical activity has a significant impact on the results of functional fitness tests. Data on favorite types of physical activity of Russian male students show a preference for young men to physically dominate their peers. Health preservation and health care are not the main aim of students.

This article discusses the different styles of professional activity of a teacher of higher education of a pedagogical profile. The purpose of the study: to develop the basic characteristics of the styles of professional activity of teachers in the humanitarian, natural sciences and physical education and sports areas of teacher education and experimentally prove the effectiveness of their implementation in the process of interaction "teacher-student". The obtained statistical data in the study prove the need for differentiation of styles of professional activity for students of various training profiles of the pedagogical institute. Based on the style of the teacher’s professional activity and the direction of the student’s pedagogical training, a reliably positive result was revealed in increasing the academic performance of students of the pedagogical institute.
