ABSTRACT: Corrêa Neto, VG, Silva, DdN, Palma, A, de Oliveira, F, Vingren, JL, Marchetti, PH, da Silva Novaes, J, and Monteiro, ER. Comparison between traditional and alternated resistance exercises on blood pressure, acute neuromuscular responses, and rating of perceived exertion in recreationally resistance-trained men. J Strength Cond Res 38(5): e211-e218, 2024-The purpose of this study was to compare the acute effects of traditional and alternated resistance exercises on acute neuromuscular responses (maximum repetition performance, fatigue index, and volume load), rating of perceived exertion (RPE), and blood pressure (BP) in resistance-trained men. Fifteen recreationally resistance-trained men (age: 26.40 ± 4.15 years; height: 173 ± 5 cm, and total body mass: 78.12 ± 13.06 kg) were recruited and performed all 3 experimental conditions in a randomized order: (a) control (CON), (b) traditional (TRT), and (c) alternated (ART). Both conditions (TRT and ART) consisted of 5 sets of bilateral bench press, articulated bench press, back squat, and Smith back squat exercises at 80% 1RM until concentric muscular failure. The total number of repetitions performed across sets in the bench press followed a similar pattern for TRT and ART, with significant reductions between sets 3, 4, and 5 compared with set 1 (p < 0.05). There was a significant difference for set 4 between conditions with a lower number of repetitions performed in the TRT. The volume load was significantly higher for ART when compared with TRT. TRT showed significant reductions in BP after 10-, 40-, and 60-minute postexercise and when compared with CON after 40- and 60-minute postexercise. However, the effect size illustrated large reductions in systolic BP during recovery in both methods. Thus, it is concluded that both methods reduced postexercise BP.

Body mass index and sex differences for mortality in hospitalized COVID-19 patients: a path analysis using a brazilian national database.

Previous studies have shown that associations between obesity and other comorbidities favor worse outcomes in COVID-19. However, it is not clear how these factors interrelate and whether effects on men and women differ. We conducted an observational, cross-sectional study using a national COVID-19 inpatient database. We studied differences in direct and indirect effects of obesity and comorbidities according to sex and body mass index (BMI) categories in hospitalized COVID-19 patients in Brazil using path analysis models and logistic regression. For men, path analysis showed a direct association between BMI and death and a negative correlation of death and chronic cardiovascular disease (CCD). For women, the association of BMI and death was indirect, mediated by admission to the ICU and comorbidities and association with CCD was non-significant. In the logistic regression analyses, there was a positive association between death and BMI, age, diabetes mellitus, kidney and lung diseases and ICU admission. We highlight the need to consider the distinct impact of obesity and sex on COVID-19, of monitoring of BMI and of the design for specific male-targeted approaches to manage obesity.

CERRADO SMALL MAMMALS: abundance and distribution of marsupials, lagomorphs, and rodents in a Neotropical savanna.

Patterns in distribution and local abundance of species within a biome are central concerns in ecology and allow the understanding of the effects of habitat loss on rates of species extinction; provide support for the creation and management of reserves; and contribute to the identification and quantification of the processes that allow niche partitioning by species. However, despite the importance in the conservation and management of the ecosystems, most systematized information on the abundance and distribution of small mammals is restricted to the northern hemisphere or forest ecosystems. For tropical biomes, an important part of this information remains dispersed and difficult to access in the form of theses, technical reports, or unpublished data sets. Here we present a comprehensive data set of abundance and richness of small mammals in the Cerrado, the largest Neotropical savanna. This data set includes 2,599 records of 446 sites from 96 studies. More than 50% of references in this data set are peer-reviewed journal articles, but 45.78% of communities were compiled from theses. The data set comprises 24,283 individuals of 55 genera and at least 118 species of small mammals including 29 marsupials, two lagomorphs (one exotic), and 87 rodents (three exotic). Local species richness ranged from 1 to 26 species (5.82 ± 3.55, average species richness ± SD). We observed hyperdominance of a few species; the 10 most abundant species in this data set represented 60.19% of all recorded individuals. The hairy-tailed bolo mouse (Necromys lasiurus) represented over than 20% of all individuals and occurred at more than 50% of sites. Furthermore, we identified 18 environments, 16 native vegetation types, and 2 anthropic environments. Typical savanna and gallery forest were the most frequently sampled vegetation types (comprising 46.94% of all sampled sites) and the most speciose ones (57 species for typical savanna and 53 species for gallery forest). The information contained in this data set can be used to analyze ecological questions such as the relationship between local abundance and regional distribution, the relevance of local and regional factors to community structuring, and the role of phylogenetic mechanisms in community assemblage. It can also be useful in conservation efforts in this biodiversity hotspot. No copyright, proprietary, or cost restrictions apply. Please cite this paper when the data are used in publications. We also request that researchers and teachers inform us of how they are using the data.

[Conflicts of interest in the research, production and dissemination of medicines]. / Conflitos de interesse na pesquisa, produção e divulgação de medicamentos.

This paper analyzes the debate about the ethical conflicts of the methods used by the pharmaceutical industry in the research, production and dissemination of medicines. Three aspects are examined: the involvement of medical professionals with representatives of the pharmaceutical industry; the conflicts of interest regarding their role as sponsors of scientific research; and the evaluation of drugs on human beings. It is seen that the message for health promotion comes from medicalization; the major pharmaceutical industries do not exclusively produce merchandise, but especially subjectivities. In this way, the type of order established by them is revealed.

The effect of rest interval length on multi and single-joint exercise performance and perceived exertion.

The purpose of this study was to compare repetition performance and rating of perceived exertion (RPE) with 1-, 3-, or 5-minute rest intervals between sets of multi and single-joint resistance exercises. Fifteen resistance trained men (23.6 ± 2.64 years, 76.46 ± 7.53 kg, 177 ± 6.98 cm, bench press [BP] relative strength: 1.53 ± 0.25 kg·kg(-1) body mass) completed 12 sessions (4 exercises × 3 rest intervals), with each session involving 5 sets with 10 repetition maximum loads for the free weight BP, machine leg press (LP), machine chest fly (MCF), and machine leg extension (LE) exercises with 1-, 3-, 5-minute rest intervals between sets. The results indicated significantly greater BP repetitions with 3 or 5 minutes vs. 1 minute between sets (p ≤ 0.05); no significant difference was evident between the 3- and 5-minute rest conditions. For the other exercises (i.e., LP, MCF, and LE), significant differences were evident between all rest conditions (1 < 3 < 5; p ≤ 0.05). For all exercises, consistent declines in repetition performance (relative to the first set) were observed for all rest conditions, starting with the second set for the 1-minute condition and the third set for the 3- and 5-minute conditions. Furthermore, significant increases in RPE were evident over successive sets for both the multi and single-joint exercises, with significantly greater values for the 1-minute condition. In conclusion, both multi and single-joint exercises exhibited similar repetition performance patterns and RPE, independent of the rest interval length between sets.

A Randomized Controlled Trial Investigating the Effects of Undulatory, Staggered, and Linear Load Manipulations in Aerobic Training on Oxygen Supply, Muscle Injury, and Metabolism in Male Recreational Runners.

BACKGROUND: Taper is considered as a strategy to avoid overtraining and increase peak performance in athletes. Because aerobic exercise increases the level and duration of independence during the lifespan, the participation of recreational athletes has increased in running events around the world. However, the effects of using load reduction in their training and aerobic performance are still not well known. OBJECTIVES: Our goal was to compare load manipulations, using tapering-like periods in the end of recreational athletes training evaluating alterations in oxygen supply, muscle injury, and metabolism markers. METHODS: Healthy males (n = 88, 20-35 years old) were randomly distributed in groups using a combination of two mesocycles of 4 weeks, undulatory and staggered, with two daily microcycles, undulatory and linear. Undulatory-undulatory (Und-Und) and undulatory-linear (Und-Lin) groups had load reduction in the final week of training while the staggered-undulatory (Sta-Und) and staggered-linear (Sta-Lin) groups did not. Cardiorespiratory capacity (V̇O2max), body mass index (BMI), and body fat % were evaluated. Blood samples were also collected to analyze hematocrit (Ht), mean corpuscular hemoglobin (MCHC), circulating levels of hemoglobin (Hb), creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea (U), cortisol (C), free testosterone (FT), and free T/C ratio. RESULTS: After 8 weeks of training, Und-Und had the highest trend to increase V̇O2max. Both Und-Und and Sta-Lin reduced body fat %. Und-Und showed a significant increase in MCHC, T and Free T/C ratio, a positive trend to increase Ht% and Hb levels, and a trend to decrease CK, LDH, and C circulating levels. Sta-Lin presented a trend to decrease Ht% and Hb levels, a significant increase in CK, LDH, AST, ALT circulating levels, and a decrease in Free T/C ratio. CONCLUSION: The use of daily undulatory training load provides better gains for aerobic fitness while the use of staggered load, mainly associated with linear load, promotes inadequate recovery in recreational runners.

Redução de danos entre praticantes de musculação que consomem esteroides / Harm reduction among strength training practitioners who consume steroids

Resumo Esta pesquisa analisa os processos críticos para a redução de danos entre consumidores de esteroides, no contexto de academias de ginástica da região Metropolitana de Goiânia, Goiás, e os sujeitos do estudo foram selecionados por meio da técnica de Bola de Neve. Foi realizada análise de conteúdo a partir da transcrição de quinze entrevistas, e a exploração do material produzido levou à construção de quatro categorias a posteriori. Foram observadas ações - como o gerenciamento individual de riscos, a exemplo da autoexperimentação para avaliar a qualidade do produto e da automedicação na forma de terapias pós-ciclo - e, ao mesmo tempo, processos que conferem proteção à saúde, especialmente relativos às redes de apoio e à posição socioeconômica favorável dos participantes deste estudo. Considera-se importante estruturar ações proativas, contínuas e integradas de redução de danos que respondam às necessidades de saúde de quem consome esteroides, assim como implementar estratégias que superem tanto a abordagem de guerra às drogas quanto a abordagem apenas pragmática e individual do gerenciamento de riscos.

Abstract This research analyzes the critical processes for harm reduction among steroid consumers, in the context of gyms in the metropolitan region of Goiânia, Goiás. The study subjects were selected using Snowball sampling. Content analysis was carried out from the transcription of fifteen interviews, and the exploration of the produced material led to the construction of four categories a posteriori. Actions-such as individual risk management, by self-experimentation to assess the product's quality and self-medication in the form of post-cycle therapies, for example-were observed and, at the same time, processes that afford health protection, especially regarding the support networks and favorable socioeconomic position of this study's participants. Structuring proactive, continuous, and integrated harm reduction actions that respond to steroid consumers' health needs is considered important, as well as implementing strategies that overcome both the war on drugs approach and the merely pragmatic and individual approach to risk management.

Pesquisa em atividade física e saúde: a urgência de uma epistemologia decolonial / Research in physical activity and health: the urgency of a decolonial epistemology / Investigación en actividad física y salud: la urgencia de una epistemología decolonial

RESUMO O objetivo do presente ensaio é refletir acerca da ideia de uma condição colonizada das investigações em atividade física e saúde, bem como, sobre a urgência de uma agenda decolonial para o desenvolvimento de pesquisas nesta área. Assumimos que o método epidemiológico hegemônico tem sido reproduzido acriticamente e de forma submissa. Propomos, assim, romper com a colonização deste saber epidemiológico do Norte global para resolvermos nossos próprios problemas de pesquisa. Para tanto, entendemos ser urgente refletirmos sobre uma epistemologia decolonial que não esteja atrelada à perspectiva dos fatores de risco, escute com as demandas das populações, bem como, contribua para superar as iniquidades nas quais as populações estão expostas.

ABSTRACT The objective of this essay is to reflect on the idea of a colonized condition of investigations in physical activity and health, as well as on the urgency of a decolonial agenda for the development of research in this area. We assume that the hegemonic epidemiological method has been reproduced uncritically and submissively. We propose, therefore, to break with the colonization of this epidemiological knowledge of the global North in order to solve our own research problems. Therefore, we understand that it is urgent to reflect on a decolonial epistemology that is not linked to the perspective of risk factors, listens to the demands of the populations, as well as contributes to overcoming the iniquities to which populations are exposed.

RESUMEN El objetivo de este ensayo es reflexionar sobre la idea de una condición colonizada de las investigaciones en actividad física y salud, así como sobre la urgencia de una agenda decolonial para el desarrollo de investigaciones en esta área. Suponemos que el método epidemiológico hegemónico ha sido reproducido acrítica y sumisamente. Proponemos, por tanto, romper con la colonización de este saber epidemiológico del Norte global para resolver nuestros propios problemas de investigación. Por tanto, entendemos que es urgente reflexionar sobre una epistemología decolonial que no se vincule a la perspectiva de los factores de riesgo, escuche las demandas de las poblaciones, así como contribuya a la superación de las iniquidades a las que están expuestas las poblaciones.

Associação entre violência e prática de atividades físicas: uma análise bibliométrica da produção científica na Web of Science / Association between violence and physical activity: a bibliometric analysis of scientific production in the Web of Science

Behavior of Heart Rate Variability After 10 Repetitions Maximum Load Test for Lower Limbs.

The purpose of this study was to analyze the acute heart rate variability behavior after 10 repetitions maximum load test for back squat, leg press, leg extension, and leg flexion in normotensive subjects. Eight recreationally trained women (age: 21.8 ± 2.2 yrs; height: 167.6 ± 6.3 cm; weight: 61.6 ± 10.1 kg) performed two 10 repetitions maximum testing days with 48-hours rest between each one. Heart rate variability was measured in baseline and postexercise (15-, 30-, 45-, and 60-minutes) for time and frequency domain. A significant difference was identified in RMSSDms (p = 0.010; effect size = -1.3), MRRms (p = 0.026; effect size = -1.3), MHR (p = 0.006; effect size = 1.4), and PNN50% (p = 0.006; effect size = -1.6) when compared 15 minutes postexercise with baseline. For all others comparison and index were no differences (p > 0.05). The present study demonstrates that load test, although works with maximum intensities, did not generate an exacerbated postexercise sympathetic activity. Thus, it seems to be safe for cardiovascular healthy individuals. As a practical application, these results can encourage exercise practitioners to do a maximum load test to resistance training loads prescription.

How to Control the Airborne Contamination in Laboratory Analyses of Microplastics?

Abstract: Numerous studies have quantified microplastics in biological and environmental samples in recent years, but contamination by airborne microplastic particles during laboratory analysis remains an unsettling possibility. We designed and tested a protocol to minimize airborne contamination during the screening of samples in laboratory conditions in order to increase the level of certainty that microplastics counted really comes from samples. Despite the care and default measures in laboratory routine, some airborne contamination in blanks was found (3.8%) at the beginning of sample screenings. After introducing more stringent procedures on our airborne contamination control protocol (ACC Protocol), a highly significant (p<0.0001) reduction was registered (1.1%). Thus, we prove that the use of a more stringent protocol should be an essential part of future studies quantifying microplastics in any samples. This study concludes that a protocol with simple, low-cost, but stringent measures can reduce airborne microplastic contamination, being applicable to any laboratory setting.

Análise dos discursos e imagens presentes no capítulo sobre Educação Física Escolar no Guia de Atividade Física para a População Brasileira / Analysis of the discourses and images present in the chapter on school physical education in the Guide to Physical Activity for the Brazilian Population / Análisis de los discursos e imágenes presentes en el capítulo sobre educación física escolar de la Guía de Actividad Física para la Población Brasileña

RESUMO O objetivo deste trabalho foi analisar os discursos e imagens sobre a Educação Física Escolar presentes no Guia de Atividade Física para a População Brasileira. Realizou-se uma pesquisa documental, de abordagem qualitativa, a partir da análise do discurso e do conteúdo visual envolvendo o capítulo. A Educação Física Escolar, nas recomendações do guia, assume uma visão funcionalista e utilitarista do movimento humano. Entende-se o avanço promovido pelo guia, sobretudo ao incentivar e valorizar a Educação Física Escolar no Brasil. Contudo, é fundamental transformar o discurso vigente, de caráter predominantemente biomédico, em uma abordagem que valorize a cultura corporal em suas múltiplas contribuições para a formação dos estudantes.

ABSTRACT The aim of this work was to analyze the discourses and images about school physical education present in the Guide of Physical Activity for the Brazilian Population. A documental research of qualitative approach was carried out, based on the Discourse Analysis and the Visual Content involving the chapter. School physical education, in the recommendations of the Guide, assumes a functionalist and utilitarian view of human movement. It is understood the progress promoted by the Guide, especially by encouraging and valuing school physical education in Brazil. However, it is essential to transform the current discourse, predominantly biomedical, into an approach that values body culture in its multiple contributions to the formation of students.

Educação física e mídia: perspectivas docentes sobre a abordagem dos temas corpo e saúde na escola / Physical education and media: the teaching perspective on the approach of the body and health issues at school / Educación física y medios de comunicación: la perspectiva docente sobre el enfoque del cuerpo y la salud en la escuela

O estudo objetiva dialogar com docentes de Educação Física sobre o poder que o discurso midiático exerce sobre a formação de opinião do público, considerando os temas "corpo e saúde", e identificar espaços dedicados ao assunto nas aulas ministradas à Educação Básica, evidenciando possibilidades e desafios de sua abordagem. A produção de dados ocorreu através de uma Roda de Conversa efetivada junto a docentes que cursaram uma especialização em Educação Física Escolar. Desse diálogo, emergiram alternativas que contribuem para a decolonização de subjetividades ligadas às noções de corpo e saúde, além da superação do pensamento abissal na produção de conhecimentos, indo ao encontro do pensamento de Boaventura de Sousa Santos (AU).

The study aims to dialogue with Physical Education teachers about the power that the media discourse exerts on the formation of public opinion, considering the themes "body and health" and identify spaces dedicated to the subject in classes taught to basic education, highlighting the possibilities and challenges of its approach. The production of data occurred through a Conversation Wheel carried out with teachers who attended a specialization in School Physical Education. From the dialogue, alternatives emerged that contribute to the decolonization of subjectivities linked to the notions of body and health and overcoming the abyssal thinking in the production of knowledge, in line with the thinking of Boaventura de Sousa Santos (AU)

Fatores associados à prática de atividades físicas durante a pandemia da COVID-19 no estado do Rio de Janeiro, Brasil / Factors associated with physical activity during the COVID-19 pandemic in Rio de Janeiro, Brazil

A relação entre os determinantes sociais e a prática de atividade física em um período de distanciamento social ainda é desconhecida. O presente estudo teve como objetivo analisar os fatores associados à prática de atividade física durante o distanciamento social induzido pela pandemia da COVID-19. Foi realizado um estudo observacional do tipo transversal com indivíduos maiores de 18 anos. A coleta de dados foi realizada de 28 de abril a 11 de maio de 2020 por meio de um questionário eletrônico online. Participaram da pesquisa 1.138 indivíduos residentes do estado do Rio de Janeiro. A maior parte dos indivíduos eram do sexo feminino (63,1%), brancos (61,9%) e estavam na faixa etária de 18 a 39 anos (60,5%). A prática de atividades físicas foi relatada por 66,1% dos entrevistados. Foram analisadas, via modelos de regressão logístico e logístico ordinal variáveis sociodemográficas, participação em atividades físicas e a frequência desta prática. As variáveis associadas com a maior chance de praticar atividades físicas durante o distanciamento foram o sexo masculino, idade acima de 40 anos, maior escolaridade, não ser profissional de serviço essencial e não ter filhos. As chances de praticar atividades físicas com maior frequência também esteve associada ao sexo masculino, a idade acima de 40 anos, não ser profissional de serviço essencial e não ter filhos. Conclui-se que a prática de atividades físicas durante o período de distanciamento social está associada aos determinantes sociais. Assim, recomendamos que políticas de promoção de atividades físicas tenham um olhar prioritário para os grupos de maior vulnerabilidade

The relationship between social determinants and the practice of physical activity in a period of social distance is still unknown. The present study aimed to analyze the factors associated with the practice of physical activ-ity during the social distance induced by the pandemic of COVID-19. An observational cross-sectional study was conducted with individuals over 18 years of age. Data collection was carried out from April 28 to May 11, 2020 through an online electronic questionnaire. Participated in the research 1,138 individuals residing of the state of Rio de Janeiro. Most individuals were female (63.1%), white (61.9%) and were aged between 18 and 39 years (60.5%). The practice of physical activities was reported by 66.1% of respondents. Sociodemo-graphic variables, participation in physical activities and the frequency of this practice were analyzed using logistic regression and ordinal logistic models. Individuals who had a higher chance of practicing physical activity during the pandemic were greater chance of practicing physical activities during the distance were male, aged over 40 years, who had higher education, not being an essential service professional and not having children. The chances of practicing physical activities more frequently were also associated with men, being over 40 years old, not being an essential service professional and not having children. It is concluded that the practice of physical activities during the period of social distance is associated with social determinants. Therefore, we recommend that policies to promote physical activities prioritize the most vulnerable groups

Enzootic transmission of Trypanosoma cruzi and T. rangeli in the Federal District of Brazil.

The Federal District of Brazil (DF) lies within the Cerrado biome, where open shrubland (savannas) is interspersed with riverside gallery forests and permanent swamps (veredas). Trypanosoma cruzi-infected native triatomines occur in the area, but the enzootic transmission of trypanosomatids remains poorly characterized. A parasitological survey involving sylvatic triatomines (166 Rhodnius neglectus collected from Mauritia flexuosa palms) and small mammals (98 marsupials and 70 rodents, totaling 18 species) was conducted in 18 sites (mainly gallery forests and veredas) of the DF. Parasites were isolated, morphologically identified, and characterized by PCR of nuclear (mini-exon gene) and kinetoplast DNA (kDNA). Six R. neglectus, seven Didelphis albiventris and one Akodon cursor were infected by trypanosomes; wild reservoir infection is documented for the first time in the DF. kDNA PCR detected T. cruzi in five R. neglectus and mini-exon gene PCR revealed T. cruzi I in isolates from D. albiventris. Parasites infecting one bug yielded T. rangeli KP1+ kDNA amplicons. In spite of the occurrence of T. cruzi-infected D. albiventris (an important wild and peridomestic reservoir) and R. neglectus (a secondary vector displaying synanthropic behavior), a low-risk of human Chagas disease transmission could be expected in the DF, considering the low prevalence infection recorded in this work. The detection of T. rangeli KP1+ associated with R. neglectus in the DF widens the known range of this parasite in Brazil and reinforces the hypothesis of adaptation of T. rangeli populations (KP1+ and KP1-) to distinct evolutionary Rhodnius lineages.

[Spatial distribution of Triatominae populations (Hemiptera: Reduviidae) in Mauritia flexuosa palm trees in Federal District of Brazil]. / Distribuição espacial de populações de triatomíneos (Hemiptera: Reduviidae) em palmeiras da espécie Mauritia flexuosa no Distrito Federal, Brasil.

To determine and analyze the distribution of Triatominae sylvatic populations in the Federal District of Brazil, 150 Mauritia flexuosa palm trees were sampled in six veredas of different landscapes (sylvatic, rural and peri-urban) in the rainy season. Triatomines were morphologically identified and grouped by sex and nymphal stage and were examined to verify infection by Trypanosoma cruzi and Trypanosoma rangeli. Twenty eight (18.6%) palm trees were infested by Rhodnius neglectus and fourteen (9.5%) by Psammolestes tertius. The frequency of Triatominae in palm trees with and without nests was significantly different being higher in palm trees with bird and mammal nests in the crown. The higher average number of insects/palm tree was observed in rural areas with estimates of up to 838 insects/hectare. The species age makeup presented a different pattern, with nymphs predominant for Rhodnius neglectus and adults predominant for Psammolestes tertius. Also, many Rhodnius neglectus eggs were collected, which indicates a reproductive event in February 2003. Among the nests found in palm trees, that of the Phacellodomus ruber (Furnariidae) bird had the greatest abundance of Triatominae, occurring on 42% of palm trees. The relative abundance of Rhodnius neglectus and Psammolestes tertius was greater in rural areas which contained higher number of nests in palm trees and lesser density of palms per hectare. None of the 96 triatomines examined were infected by Trypanosoma cruzi or Trypanosoma rangeli, despite our finding of Rhodnius neglectus infection by those parasites in former studies.
