Correlation between muscular injuries and stress in handball athletes in wheelchair

Verificar a correlação entre microlesão muscular e o nível de estresse psicológico em atletas de Handebol em Cadeiras de Rodas (HCR). Metodologia: As microlesões foram identificadas pelas concentrações da proteína creatina quinase (CK) em amostras sanguíneas de 10 atletas masculino, coletadas 10 minutos antes e após o final do jogo. O nível de estresse derivou-se do questionário RESTQ-sport aplicado 30 minutos antes do jogo. Os atletas não apresentaram aumentos significativos nos níveis de CK (p = 0,766). Observando o nível de estresse e recuperação, nota-se escores elevados (>4,0) nas escalas relacionadas aos eventos potencialmente tranquilizantes. Quanto as escalas relacionadas aos eventos estressantes, verificou-se escores moderados nas escalas de Conflitos/Pressão (3,5 ± 0,6) e Lesões (3,2 ± 1,3). A correlação entre a CK e os níveis de estresse e recuperação, nos momentos pré e pós jogo, apresentaram correlação moderada nas escalas fadiga (r = -0,46; r = -0,61), lesões (r = -0,47; r = -0,55), perturbações nos intervalos ( r= -0,47; r = -,069) e Estar em forma (r = 0,44; r = 0,41). Os resultados demonstram que não houve aumento significativo nos níveis séricos de Ck e correlação moderada em algumas escalas de estresse e recuperação nos atletas usuários de cadeira de rodas17To verify the correlation between muscle microlesionand the level of psychological stress among wheelchair handball athletes (WHA). Methodology: Micro-lesions were identified by creatine kinase protein (CK) concentrations in blood samples from 10 male athletes, which was collected 10 minutes before and after the end of the game. The level of stress was derived from the RESTQ-sport questionnaire applied 30 minutes before the game. The athletes did not show significant increases in CK levels (p=0.766). Observing the level of stress and recovery, high scores (>4.0) are noted in the scales related to potentially tranquilizing events. Regarding the scales related to stressful events, there were moderate scores at subscales of Conflict/Pressure (3.5 ± 0.6) and Injuries (3.2 ± 1.3). The correlation between CK and stress and recovery levels in pre and post-game moments showed a moderate correlation in fatigue (r = -0.46; r = -0.61), injury (r = -0.47; r = -0.55), disturbances at intervals (r = -0.47; r = -, 069) and being in shape (r = 0.44; r = 0.41). The results show that there was no significant increase in CK levels and moderate correlation with some stress and recovery scales among wheelchair athlete

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
