Eccentric Resistance Training in Youth: Perspectives for Long-Term Athletic Development

The purpose of this narrative review is to discuss the role of eccentric resistance training in youth and how this training modality can be utilized within long-term physical development. Current literature on responses to eccentric exercise in youth has demonstrated that potential concerns, such as fatigue and muscle damage, compared to adults are not supported. Considering the importance of resistance training for youth athletes and the benefits of eccentric training in enhancing strength, power, speed, and resistance to injury, its inclusion throughout youth may be warranted. In this review we provide a brief overview of the physiological responses to exercise in youth with specific reference to the different responses to eccentric resistance training between children, adolescents, and adults. Thereafter, we discuss the importance of ensuring that force absorption qualities are trained throughout youth and how these may be influenced by growth and maturation. In particular, we propose practical methods on how eccentric resistance training methods can be implemented in youth via the inclusion of efficient landing mechanics, eccentric hamstrings strengthening and flywheel inertia training. This article proposes that the use of eccentric resistance training in youth should be considered a necessity to help develop both physical qualities that underpin sporting performance, as well as reducing injury risk. However, as with any other training modality implemented within youth, careful consideration should be given in accordance with an individual's maturity status, training history and technical competency as well as being underpinned by current long-term physical development guidelines

Nael, herdeiro testamentário: a terceira margem da gemelidade em Dois irmãos, de Milton Hatoum

Nael, narrador de Dois irmãos, segundo romance de Milton Hatoum, é inicialmente um personagem quase imperceptível, pois recolhe os testemunhos no seio do grupo familiar de que é filho bastardo a fim de elaborar sua história. Ao longo da narrativa, seu verdadeiro desejo é desvelado: conhecer a identidade de seu pai e, assim, filiar-se. Incapazes de organizar a herança imaterial dessa família, os irmãos gêmeos Yaqub e Omar desencadeiam seu desmoronamento. Nael, executor testamentário, organiza o caos familiar e conforma sua identidade em um movimento que parte do outro em direção a si mesmo

Ultraviolet‐C as a viable reprocessing method for disposable masks and filtering facepiece respirators

In normal conditions, discarding single-use personal protective equipment after use is the rule for its users due to the possibility of being infected, particularly for masks and filtering facepiece respirators. When the demand for these protective tools is not satisfied by the companies supplying them, a scenario of shortages occurs, and new strategies must arise. One possible approach regards the disinfection of these pieces of equipment, but there are multiple methods. Analyzing these methods, Ultraviolet-C (UV-C) becomes an exciting option, given its germicidal capability. This paper aims to describe the state-of-the-art for UV-C sterilization in masks and filtering facepiece respirators. To achieve this goal, we adopted a systematic literature review in multiple databases added to a snowball method to make our sample as robust as possible and encompass a more significant number of studies. We found that UV-C’s germicidal capability is just as good as other sterilization methods. Combining this characteristic with other advantages makes UV-C sterilization desirable compared to other methods, despite its possible disadvantages.The authors would also like to acknowledge the project PLASMAMED—PTDC/CTM‐ TEX/28295/2017 financed by Fundação para Ciência e a Tecnologia (FCT), Fundo Europeu de Desenvolvimento Regional (FEDER) and Programa Operacional Competitividade e Internacionalização (POCI) in the frame of the Portugal 2020 program

ACA Methodology - Accessibility Conformity Assessment: update procedure

Projetar ambientes que possam dar autonomia aos idosos com mobilidade reduzida e às pessoas com deficiência é fundamental para a inclusão social do indivíduo. Assim, identificar a relação existente entre o usuário e o meio edificado para adequar o espaço às características do usuário. Nesse sentido, o projeto de arquitetura sem barreiras se justifica como uma contribuição para a inserção social. Partindo deste pressuposto o presente artigo apresenta a relação existente entre a ação projetual e a avaliação quantitativa da acessibilidade através do método de Avaliação de Conformidade da Acessibilidade (ACA) - bem como a sua adequação em face da atualização da NBR 9050 - como contribuição para o desenvolvimento de espaços acessíveis que sigam os parâmetros da ergonomia e do desenho universal.Designing environments that can give autonomy to the elderly with reduced mobility and to people with disabilities is fundamental for the social inclusion of the individual. Thus, identifying the relationship between the user and the built environment is necessary to tailor the activities to the characteristics of the user. In this sense, the project of architecture without barriers is justified as a contribution to social insertion. Based on this assumption, the present article presents the relationship between the design action and the quantitative assessment of accessibility through the Accessibility Conformity Assessment (ACA) method - aswell asits adequacy in view of the NBR 9050 update - as a contribution to the development of accessible spaces that follow the parameters of ergonomics and universal design
