THE EFFECT OF FRACTIONATED RED BEETROOT JUICE ON PERFORMANCE AND OVERALL HEALTH OF A HIGH-PERFORMANCE ATHLETES
Get PDFOver the past 20 years, nitric oxide has become the turning point in athlete physiology and medical research. It has been observed in scientific studies that there are very different protocols for the use of nitrates (red beetroot juice) and different research methodology and results. The most effective solutions for improving the performance of athletes are still being sought. The purpose of this research is to investigate the performance and overall health of a high-performance athlete after consuming fractionated red beetroot juice. The investigation is a one-case study. The respondent is a high-class athlete - track and field (middle and long distance), 20 years old. Three tests were performed in laboratory conditions with an interval of one week. The first test was without the use of fractionated red beetroot juice, the second test after a single dose, and the third after 7 days of use. The research used an interview of the respondent, cardio pulmonary exercise testing measuring device "Vyntus CPX" with gas analysis on a bike ergometer and determination of blood lactate concentration. In the experiment, the athlete\u27s VO2max improved during each test, after one dose by 9%, and after 7 days of use by 13% from the first test. The physical overall health at the end of the test worsened each time, but in the previous tests, where fractionated red beetroot juice was used, a faster recovery of the athlete\u27s working capacity after exercise was observed
COMPARISON OF COMPETITIVE ACTIVITY INDICATORS AT 100 M DISTANCES OF LATVIAN AND EUROPEAN SWIMMERS
Get PDFThe research aimed to study the performance characteristics of male and female finalists at a 100m distance when swimming at the Latvian swimming championships in a period from 2018 to 2020 (in the 50m pool). 262 final heats got analyzed. The results of the 3 best Latvian swimmers, males=36, and females-36, at each 100m distance (freestyle, breaststroke, backstroke, and butterfly) at championships in 2018, 2019, and 2020 have been analysed. The parameters for overcoming competitive distance: competitive result in the 100-meter distance; the start reaction time; time for the 15 meters mark; speed to the 15 meters mark; the time of the turn 5 meters up to the wall and 15 meters after the turn; underwater distance and time after the start and after turning; time of “clear” swimming. The obtained results were compared to the characteristics of overcoming the same competitive distance by the finalists of the European Championship 2016. As a result of comparative analysis, statistically, significant differences were found in such parameters of competitive activity as the overall result, overcoming of starting and turning parts, and the distance covered under water after the turn and start. Statistically significant differences were not found in the reaction time to the start signal and in the speed of “clear” swimming. The comparative analysis of the performance characteristics of the European Championships finalists showed possibilities for further improvements of Latvian swimmers. The aim: is to determine the performance parameters of the Latvian best swimmers and compare them with the same parameters of the finalists of the European Championship 2016.
THE CONCEPT AND LEGAL CHARACTERISTICS OF THE INSTITUTE OF MEDIATION
Get PDFMediation is one of the alternative dispute resolution methods. In recent years, mediation as an institute has developed very rapidly. Resolving disputes through alternative methods can be much faster, more efficient and the end result is satisfactory to both parties. Disputes as such have existed since the beginning of humanity. Therefore, in today\u27s world, this type of alternative dispute resolution needs to be developed in order to deal more successfully and effectively with the relations of modern society. Nowadays, there is an increasing development of society and technology, as a result of which mediation as a legal institution will develop more and more rapidly. In Latvia, mediation is regulated by the Mediation Law. The regulation of Latvian legislation must be developed so that mediation as an institute can also develop
ENERGY EFFICIENCY OF BUILDINGS TODAY
Get PDFNowadays, we hear the words energy efficiency and zero energy building more and more often. The concept of zero-energy building and energy-efficient building is becoming the goal of building design. Sustainable construction, which includes proper methods, materials, technologies, can ensure environmentally friendly use of natural resources and mitigation of global warming. Construction is an industry that does not stand still and almost all the time we see the construction of new buildings, the renovation of existing buildings, etc., but do these buildings meet modern standards? The authors will perform the necessary calculations to find out to what extent a real construction object meets modern requirements and how the energy efficiency of this object could be further improved
MUNICIPAL LIVING PREMISES RENT PROBLEMS
Get PDFThe need for a place to live has always been a pressing problem for society. Several municipalities in Latvia are building new rental houses to provide their residents with a place to live. However, not all residents have the opportunity to apply for a municipal apartment for rent it. The problems also affect the municipalities themselves, which often end up in the role of hostages in the fight with tenants who do not pay rent, as well as when concluding rental agreements in order to fulfil the requirements of the law
CIRCULAR ECONOMY STRATEGIES FOR REDUCING FOOD WASTE IN SCHOOLS: A SYSTEMATIC LITERATURE REVIEW
Get PDFPurpose and aim of the study: As the transition to a circular economy (CE) and the reduction of food waste is a priority strategic goal for policy planning at global and European Union (EU) level, but food waste in catering has become a major sustainability issue, the aim of the paper is to identify CE strategies to reducing food waste in schools based on a systematic literature review.Design / Methodology / Approach: The research employed qualitative methods: five-step systematic literature review methodology by Denyer & Tranfield, (2009), analysis and synthesis, as well as the monographic method. The literature was selected using the databases Google Scholar, MDPI, ScienceDirect and Scopus.Main Findings: Based on the systematic literature review, approaches for implementing CE strategies to reduce food waste in school canteens were discovered.Originality: This study provides a new perspective on the implementation of CE “R strategies” to reduce food waste in schools.Implications: The results of the study can be a basis for school and canteen administration to implement CE policies and waste management practices that will promote responsible food consumption and support sustainable food consumption and waste reduction strategies, and create added value for school canteens, the environment and society in general
METODOLOGICAL ASPECTS OF THE FORMATION OF AN ENTREPRENEURIAL ECOSYSTEM
Get PDFPurpose and aim of the study: The purpose of the study is to determine the theoretical and conceptual foundations of the process of forming an entrepreneurial ecosystem. The task of the study is to summarize the theoretical and methodological support of the studied issues and to substantiate the methodological approach to the formation of an entrepreneurial ecosystem.Design /Methodology / Approach: The study used general scientific and special methods: scientific abstraction, analysis and synthesis, induction and deduction, systemic and comparative analysis, structural and logical, an ascent from the abstract to the concrete, and the method of parametric estimates. The literature was selected using the databases Google Scholar, MDPI, Science Direct and Scopus.Main Findings: The analysis of the theoretical and methodological aspects of the entrepreneurial ecosystem and the formation of its structure shows that there is no systematic approach to determining the links and nature of interaction (including inter-level interaction) between different participants of the entrepreneurial ecosystem. It has been established that the structure of entrepreneurial ecosystems is unique and is able to provide systemic support for entrepreneurial activity by providing access to markets, finance, human and intellectual capital.Originality: The study reveals the process of formation of the entrepreneurial ecosystem in the aspect of developing a strategy for the entry of new enterprises into it.Implications: The results of the study make it possible to synthesize the ideas of territorial models of innovation and entrepreneurship, to carry out strategic positioning of the enterprise in the entrepreneurial ecosystem in order to provide attractive value propositions for consumers in the long term
ANALYSIS OF THE ACTIVITY OF THE FARM "MALAINE" IN THE DAIRY FARMING SECTOR
Get PDFMilk production takes place in all EU countries and constitutes a significant part of the value of EU agricultural production. When producing and processing milk, it is important to be able to realize and maintain your economic activity with it. Therefore, the first thing that milk producers and processors do is satisfy the local demand for milk. If more milk is produced than is consumed in the given country, then it is necessary to start thinking about exports that would be able to compete with the products that are already in the planned export markets. Latvia is also on the list of countries that produce more milk than is needed for self-consumption.
The main type of activity and source of income of farm "Malaine" is side farming, but the farm is also engaged in grain farming, which helps to get additional profit in unstable years and provides its farm with high-quality feed for dairy cattle. The farm has more than 100 dairy cows. The number of dairy cows is independently increased by breeding work, selecting only the best calves from the most worthy cows
