Composição corporal, consumo alimentar e hidratação de praticantes de musculação

O objetivo deste estudo foi avaliar a composição corporal, consumo alimentar e hidratação de praticantes de musculação de uma academia da cidade de Lavras-MG. Participaram do estudo 30 praticantes de musculação, sendo 15 homens (24,2 ± 4,1 anos) e 15 mulheres (24,4 ± 6,2 anos). A composição corporal foi determinada pelo método de dobras cutâneas. O consumo alimentar foi determinado utilizando três registros alimentares de 24h coletados em dias não consecutivos e analisados no software Dietpro 5i. A hidratação foi avaliada durante o treino utilizando a diferença entre a massa corporal inicial e final para determinar a perda ou ganho hídrico. Os homens apresentaram percentual de gordura corporal médio significativamente menor que as mulheres (M=11,14% VS F=23,19%). Em ambos os gêneros foi observado alta prevalência de inadequação do consumo de energia, carboidratos, proteínas e cálcio sendo maior entre as mulheres. Todos participantes faziam ingestão de fibras abaixo da recomendação e de sódio acima dos valores recomendados. A ingestão de lipídios em ambos os gêneros estava adequada. A ingestão média de ferro em ambos os gêneros foi superior aos valores recomendados. A inadequação do consumo de vitamina C foi maior entre os homens. A maioria dos avaliados (86,5%) terminou o treino hiperidratado. A partir dos dados obtidos conclui-se que a população investigada apresenta hábitos alimentares que não atendem adequadamente suas necessidades nutricionais e realiza ingestão excessiva de líquidos. Assim, é importante a ação do nutricionista esportivo dentro de academias para melhorar o perfil nutricional dessa população. ABSTRACT Body composition, hydration and food consume of bodybuildersThe aim of this study was to evaluate body composition, food consumption and bodybuilder’s hydration of a gym in Lavras City, MG. Participated in the studies 30 bodybuilders, being 15 men (24.2 ± 4.1 years old) and 15 women (24.4 ± 6.2 years old). The body composition was determined by skinfold method. The food consumption was determined as of gathering of three 24h records in nonconsecutive day and analyzed in the software Dietpro 5i. The hydration was evaluated during the training using the difference between initial body mass and final body mass to ascertain water loss or water gain. The men presented medium body fat’s percentage meaningfully smaller than women (M=11.14% VS F=23.19%). Both genres were observed inadequacy’s high prevalence of energy consumption, carbohydrates, proteins and calcium being higher among women. All attendees were intake of fibers below the recommended level and sodium above recommended values. The lipid’s intake in both genres were accurate. The average intake of iron in both genres were superior to the recommended values. The inadequacy of Vitamin C’s consumption was higher among men. Most of the evaluated bodybuilders (86,5%) finished the training overhydrated. As of obtained data it was conclude that investigated population presents food habits that don’t adequately attend its nutritional needs and it performs excessive intake of liquids. So, it is important to sport nutritionist act inside gym to improve nutritional profile bodybuilder’s

Por que as tarifas foram para os céus? : propostas para o setor elétrico brasileiro

Bibliografia: p. 472-473.O sistema elétrico brasileiro é único. É um dos sistemas mais confiáveis e de mais baixo custo operacional e ambiental do mundo. Todavia, depois das privatizações, a tarifa se tornou, talvez, a mais cara do mundo e temos tido recorrentes crises energéticas. A privatização do sistema criou uma enormidade de custos desnecessários e tornou o sistema menos confiável. Para que a energia tenha tarifas razoáveis, bom planejamento ambiental e confiabilidade, é necessário voltarmos ao sistema de remuneração pelo custo e ter novamente a Eletrobrás no gerenciamento e no planejamento do sistema.The Brazilian electric system is unique. It is one of the most reliable systems in the world, not to mention it has the lowest operational and environmental costs. Nevertheless, after privatizations, the rates have become the highest ones in the world and we have faced several power crises. The privatization of the system generated several unnecessary costs and made the system become less reliable. For the electric power to have reasonable rates, good environmental planning and reliability, we need to use the costof-service system again and assign to Eletrobrás the duty of managing and planning the system

Building a National IoT Plan: Policy Recommendations and the Case of Brazil

The Internet of Things (“IoT”) is an expression that refers to a whole set of new services and devices that includes at least three fundamental aspects: connectivity, use of sensors or actuators, and computational capacity for data processing and storage. The Internet of Things goes beyond connecting objects to each other; it also gives them the power to process data (thereby making them "smart"). For developing countries such as Brazil, the opportunities offered by the Internet of Things can compensate for shortcomings in infrastructure and services, and can improve innovation, quality of life, productivity, and even the economic complexity of our basket of export products. However, the way in which each country will seize this opportunity will depend on its specific aspirations and strategies. The broader economic, social, political, and legal context of the country should be considered, as well as the local development of information and communication technologies. For this reason, the National Bank for Economic and Social Development (BNDES), in partnership with the Ministry of Science, Technology, Innovation and Communications (MCTIC), has commissioned this study, "Internet of Things: An Action Plan for Brazil." This study, mapped by a consortium comprised by McKinsey & Company, the CPqD Foundation, and Pereira Neto | Macedo Law Firm, outlines the local technological and economic challenges related to the topic, as well as well as how to address legal issues inherent to the development of IoT in Brazil

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
