Resumo Em todo o mundo, a agricultura convencional faz uso extensivo de pesticidas. Embora os efeitos dos herbicidas sejam relativamente bem conhecidos em termos de impactos ambientais em organismos não-alvo, há pouca evidência científica sobre os impactos de resíduos de herbicidas em artrópodes aquáticos de áreas de conservação tropicais. Este estudo avalia pela primeira vez a toxicidade dos herbicidas ametryn, atrazine e clomazone sobre o inseto aquático Limnocoris submontandoni (Hemiptera: Naucoridae). A concentração letal (LC50) de herbicidas foi avaliada para esses insetos, bem como o efeito dos herbicidas nos tecidos e testículos dos insetos. A LC50 estimada foi de 1012,41, 192,42 e 46,09 mg/L para clomazone, atrazine e ametryn, respectivamente. Alterações nos espermatócitos e espermátides foram observadas sob o efeito de atrazine, e efeitos na espermatogênese foram observados para algumas concentrações de clomazone, com aparente recuperação após um curto período de tempo. Nossos resultados fornecem informações úteis sobre os efeitos de resíduos de herbicidas em sistemas aquáticos. Essas informações podem ajudar a minimizar o risco de efeitos reprodutivos de longo prazo em espécies não-alvo que foram negligenciadas anteriormente em estudos de ecotoxicologia.

Abstract Worldwide, conventional agriculture makes extensive use of pesticides. Although the effects of herbicides are relatively well known in terms of environmental impacts on non-target organisms, there is very little scientific evidence regarding the impacts of herbicide residues on aquatic arthropods from tropical conservation areas. This study evaluates for the first time the toxicity of the herbicides ametryn, atrazine, and clomazone on the aquatic insect Limnocoris submontandoni (Hemiptera: Naucoridae). The lethal concentration (LC50) of herbicides was evaluated for these insects, as well as the effect of the herbicides on the insects’ tissues and testicles. The estimated LC50 was 1012.41, 192.42, and 46.09 mg/L for clomazone, atrazine, and ametryn, respectively. Spermatocyte and spermatid changes were observed under the effect of atrazine, and effects on spermatogenesis were observed for some concentrations of clomazone, with apparent recovery after a short time. Our results provide useful information on the effects of herbicide residues in aquatic systems. This information can help minimize the risk of long-term reproductive effects in non-target species that have been previously overlooked in ecotoxicology studies.

Hematological problems are associated with Coronavirus disease 2019 (COVID-19). Respiratory impairment is the higher point studied, although without experimental studies related to the oxygen transport performed by erythrocytes. Therefore, we decided to investigate if erythrocytes from COVID-19 patients have their functionality changed. The case-control study included hospitalized patients with a positive real-time polymerase chain reaction (RT-PCR) result admitted to University Hospital. Volunteers (negative RT-PCR results) were recruited as a control group. Thus, we assessed different erythrocytes parameters, oxidative stress markers, and biophysical studies using whole blood and isolated hemoglobin. We found a decrease of 51% in oxygen uptake and reduced antioxidant enzyme activity in COVID-19 patients compared to controls. Raman spectrometry showed structural changes in the hemoglobin and lipids of the erythrocytes from COVID-19 patients; thus, these results were consolidated with an increase in Young’s modulus in erythrocytes followed by morphology changes. Besides, isolated hemoglobin from COVID-19 patients has a distinct interaction profile using a ligand model compared to the control. COVID-19 leads to structural, functional, and morphological damage to human erythrocytes. Our data showed structural and molecular changes and induction of oxidative stress in erythrocytes by COVID-19, a new perspective on the contribution of erythrocytes to a respiratory commitment in COVID-19.

ABSTRACT Carcass classification consists of grouping animals with similar carcass characteristics. When the groups are defined a priori, as in the case of conformation and finishing scores, the interest is to identify the contribution of each variable used in separating the groups. Therefore, discriminant analysis was used to discriminate Santa Inês animals according to the conformation and carcass finishing scores (score 2 = regular, score 3 = good) and to identify the variables that most contribute to the differentiation. The conformation and carcass finishing scores vary from 1 to 5. This study used scores 2 and 3, considering that the evaluated animals ranged between these two respective scales. The database consisted of information from 122 uncastrated Santa Inês sheep submitted to the confinement regime, of which 24 variables related to the carcass of the animals were recorded. Data were submitted to the Mardia test to verify multivariate normality, followed by the nonparametric k-nearest neighbor (k-NN) test. The stepwise procedure selected a particular subset of variables, and the Mahalanobis Distance (D2) was used to assess the separation of groups (p-value ˂ 0.05). The variables with the highest discriminatory power for the carcass conformation scores were cold carcass weight (CCW), external carcass length (ECL), and neck (NEC), for carcass finishing were live weight at slaughter (LWS), ECL, and thoracic perimeter (TP). The multivariate discriminant analysis proved efficient in allocating the animals in their groups of origin.

RESUMO A classificação da carcaça consiste em agrupar animais com características de carcaça semelhantes. Quando os grupos são definidos a priori, como o caso dos escores de conformação e acabamento, o interesse é identificar a contribuição de cada variável utilizada na separação dos grupos. Diante disso, utilizou-se a análise discriminante para discriminar animais da raça Santa Inês em função dos escores de conformação e acabamento (escore 2 = razoável, escore 3 = boa) e, identificar as variáveis que mais contribuem na diferenciação. Os escores de conformação e acabamento variam numa escala de 1 a 5. Nesse estudo, foram usados escores 2 e 3 considerando que os animais avaliados variaram entre essas duas respectivas escalas. O banco de dados foi composto por 122 informações de ovinos não castrados da raça Santa Inês, submetidos ao regime de confinamento, dos quais foram registradas 24 variáveis relacionadas à carcaça dos animais. Os dados foram submetidos ao teste de Mardia, para verificar a normalidade multivariada, seguido do teste não-paramétrico k-vizinho mais próximo (K-NN). Um subconjunto particular de variáveis foi selecionado pelo procedimento stepwise e a Distância de Mahalanobis (D2) para avaliar a separação dos grupos (p-valor ˂ 0,05). As variáveis com maior poder discriminatório para os escores de conformação de carcaça foram peso de carcaça fria (PCF), comprimento externo da carcaça (CEC) e pescoço (PES), para acabamento de carcaça foram peso vivo ao abate (PVA), CEC e perímetro torácico (PT). A análise discriminante multivariada mostrou-se eficiente para alocar os animais em seus grupos de origem.

ABSTRACT The objective of this study was to evaluate the effect of either a limited forage intake or concentrate supplementation prior to the adaptation to high-concentrate diets on dry matter intake, ruminal pH, bacteria, and protozoa of Nellore cattle. The experiment was designed as a two 3×3 Latin square, and six cannulated Nellore steers were used. Each experimental period was composed by three feeding phases: pre-adaptation (14 days), adaptation (12 days), and finishing (seven days) diet, in a total of 33 days per period. The steers were assigned to one of three pre-adaptation dietary treatments: control (Tifton hay fed ad libitum + mineral supplement), restriction (Tifton hay fed at 1.4% of BW + mineral supplement), and concentrate (Tifton hay fed ad libitum + 0.5% of BW of a mix of concentrate feedstuffs and mineral supplement). The adaptation period consisted of two adaptation diets, which contained 72 and 79% concentrate for six days each. The finishing diet contained 86% concentrate. During the pre-adaptation phase, restricted cattle had higher pH than concentrate-fed cattle. There was a reduction in M. elsdenii relative population in cattle from either restriction or concentrate groups. During adaptation and finishing phases, cattle from concentrate group had smaller F. succinogenes populations compared with the control group. The previous nutritional backgrounds impact ruminal microbiota during adaptation and finishing phases without causing any negative effect on ruminal pH. Feeding concentrate prior to the adaptation positively impacted the transition to high-concentrate diets and promoted increased dry matter intake.

Abstract Simultaneous analysis studies of several agronomic traits in cultivated plants make it possible to identify phenotypic and genotypic differences due to environmental variations, such as altitude. Therefore, the objective was to evaluate, through multivariate analysis of agronomic, physicochemical and physiological characters, passion fruit hybrids cultivated in different environments. The hybrids used were Gigante Amarelo, Rubi do Cerrado and Sol do Cerrado, cultivated in the southern region of Espírito Santo in four municipalities/environments: Marataízes (41 m), Jerônimo Monteiro (104 m), Alegre (711 m), and Ibitirama (1016 m). The agronomic characters of the plants, the physical-chemical characteristics of the fruits and the physical, biochemical and physiological qualities of the seeds were analyzed. The Singh method was used to determine the most important differentiating characters between hybrids growing in different environments. Based on these characters, a dissimilarity matrix was generated and a principal coordinate analysis was performed. It was observed that the pulp yield was influenced by altitude. The three hybrids showed greater performance in terms of agronomic characters at altitude (41 m) than at altitude (104 m). The Sol do Cerrado hybrid showed high performance in the physical-chemical characteristics of the fruits at altitude (104 m).

Resumo Estudos de análise simultânea de diversos caracteres agronômicos em plantas cultivadas permitem identificar diferenças fenotípicas e genotípicas devido a variações ambientais, como a altitude. Diante disso, objetivou-se avaliar através da análise multivariada de caracteres agronômicos, fisico-químicos e fisiológicos, híbridos de maracujazeiros cultivados em diferentes ambientes. Os híbridos utilizados foram Gigante Amarelo, Rubi do Cerrado e Sol do Cerrado, cultivados na região sul do Espírito Santo em quatro municípios/ambientes: Marataízes (41 m), Jerônimo Monteiro (104 m), Alegre (711 m), e Ibitirama (1016 m). Foram analisados os caracteres agronômicos das plantas, as características físico-químicas dos frutos e as qualidades físicas, bioquímicas e fisiológicas das sementes. O método Singh foi usado para determinar os caracteres diferenciadores mais importantes entre híbridos crescendo em diferentes ambientes. Com base nesses caracteres, uma matriz de dissimilaridade foi gerada e uma análise de coordenadas principais foi realizada. Observou-se que o rendimento de polpa foi influenciado pela altitude. Os três híbridos apresentaram maior desempenho em termos de caracteres agronômicos na altitude (41 m) do que na altitude (104 m). O híbrido Sol do Cerrado apresentou alto desempenho nas características físico-químicas dos frutos na altitude (104 m).

ABSTRACT The objective of this study was to examine the effects of replacement of an antibiotic (ANT, chlorohydroxyquinoline) in the diet of weaned piglets with a prebiotic composed of β-glucans, glucomannans, and mannan-oligosaccharides on growth performance, diarrhea occurrence (DO), hematological parameters, pH of digestive content, organ weights, intestinal epithelium morphology, and intestinal bacterial counts. A total of 120 piglets (weaned at 21 d old; 6.32±0.10 kg BW) were allocated in a randomized block design, with six pens replicates and four piglets per pen as experimental unit. Treatments consisted of diets with 0, 1,000, 2,000, or 3,000 mg kg−1 of prebiotic and a basal diet with 120 mg kg−1 ANT. No differences of treatments were observed on performance, DO, pH of digestive content, organ weights, and hematological parameters. Duodenal villus density (VD) increased linearly with the prebiotic levels. In the jejunum, the prebiotic level of 2,000 mg kg−1 resulted in a greater VD compared with the ANT. Enterobacteriaceae count in the ileum and total and lactic acid bacteria counts in the cecum responded quadratically to increasing prebiotic levels. The equations estimated the prebiotic levels of 2,125, 1,167, and 1,500 mg kg−1 to provide reduced counts of the respective bacteria (ileal enterobacteria: 6.47 log CFU g−1; total cecal bacteria: 6.70 log CFU g−1; and cecal lactic acid: 7.29 log CFU g−1). Salmonella spp. was not detected, whereas Escherichia coli and Lactobacillus spp. gene copies were unaffected by the treatments. Prebiotic levels or ANT do not enhance performance or health of weanling pigs, but the effects observed on VD and microbiota profile might be an indication of the potential benefits of these products in commercial farming conditions.

Abstract Soil salinization is an environmental factor that frequently occurs in semi-arid regions around the world and seed priming technique is one of the alternatives to obtain the greatest establishment of seedlings in the field, through the induction of tolerance to environmental stresses. This research aimed to evaluate the effect of seed priming with NaCl on the induction of salinity tolerance in Myracrodruon urundeuva Allemão in vitro. The research was carried out at the Center for Strategic Technologies of the Northeast, in Recife / PE-Brazil M. urundeuva seeds were disinfected and submitted to two treatments: water (control) or NaCl (2mM), and inoculated in WPM medium at three saline concentrations (0.0; 25.0 and 50.0 mM NaCl) for 45 days. Plant height, number of leaves, fresh biomass (total, shoot, and root), shoot/root ratio, sodium and potassium and Na/K ratio, antioxidant enzyme activity, and peroxide content were evaluated malondialdehyde hydrogen. The data were subjected to variance analysis and the results were compared using the Student-Newman-Keuls test at 5% probability, using the R software. Seed priming with NaCl promoted a beneficial effect on the height of seedlings exposed to salinity. On the other hand, height was inversely proportional to saline concentrations, regardless of seed priming. The shoot/root ratio was also lower in seedlings cultivated under 25 and 50 mM NaCl. Despite being favorable for most growth variables, seed priming with NaCl induced an increase in lipid peroxidation in seedlings that were not exposed to salinity, which is linked to a decrease in the activity of antioxidant enzymes. The antagonistic response to NaCl stimulation between growth parameters and plant defense observed in the present research raises the need for further complementary studies that make it possible to delineate the metabolic alterations of M. urundeuva against a chemical stimulus to induce tolerance to a given stress.

Resumo A salinização do solo é um fator ambiental que ocorre frequentemente em regiões semi-áridas ao redor do mundo e a técnica de seed priming é uma das alternativas para se obter o maior estabelecimento de mudas no campo, através da indução de tolerância aos estresses ambientais. Este trabalho objetivou avaliar o efeito do seed priming com NaCl na indução da tolerância à salinidade em Myracrodruon urundeuva Allemão in vitro. A pesquisa foi realizada no Centro de Tecnologias Estratégicas do Nordeste, em Recife / PE-Brasil. Sementes de M. urundeuva foram desinfestadas e submetidas a dois tratamentos: água (controle) ou NaCl (2mM), e inoculadas em meio WPM em três concentrações salinas (0.0; 25.0 and 50.0 mM NaCl) por 45 dias. Foi avaliada a altura, número de folhas, biomassa fresca (total, parte aérea e raiz), razão parte aérea / raiz, sódio, potássio, razão Na / K, atividade de enzimas antioxidantes, teores de peróxido de hidrogênio e malondialdeído. Os dados foram submetidos à análise de variância e os resultados comparados pelo teste Student-Newman-Keuls a 5% de probabilidade, utilizando o software R. O priming com NaCl promoveu efeito benéfico na altura de mudas expostas à salinidade. Todavia, a altura foi inversamente proporcional às concentrações salinas, independentemente do priming. A razão parte aérea / raiz foi menor nas mudas cultivadas sob NaCl 25 e 50 mM. Apesar de ser favorável para a maioria das variáveis de crescimento, o seed priming com NaCl induziu aumento na peroxidação lipídica em mudas não expostas à salinidade, o que está relacionado à diminuição da atividade de enzimas antioxidantes. A resposta antagônica à estimulação do NaCl entre parâmetros de crescimento e defesa das plantas na presente pesquisa levanta a necessidade de novos estudos complementares que possibilitem delinear as alterações metabólicas de M. urundeuva frente a um estímulo químico para induzir tolerância a um determinado estresse.

RESUMO O objetivo do estudo foi selecionar populações F2RC1 de tomateiro anão do tipo saladete promissoras para o desenvolvimento de linhagens baseado em características agronômicas, qualidade de fruto e resistência a mosca branca. O delineamento experimental foi em blocos casualizados contendo 13 tratamentos (10 populações F2RC1 de tomateiro anão, genitores e híbrido comercial) com quatro repetições. Foram avaliados: peso, comprimento, diâmetro, formato, espessura da polpa, número de lóculos, teores de sólidos solúveis, β-caroteno e licopeno do fruto; comprimento do entrenó da planta; teores de acilaçúcares, número de ovos, ninfas e adultos de mosca branca nos folíolos. Os dados foram analisados por ANOVA, índices de seleção e análise multivariada. O primeiro retrocruzamento aumentou as características agronômicas das populações em relação ao genitor doador, principalmente para peso de fruto (169.1%), comprimento do fruto (26.1%) e diâmetro do fruto (16.6%). As populações UFU SDi 7, UFU SDi 9 e UFU-SDi 17 foram selecionadas por dois índices de seleção e são consideradas promissoras.

ABSTRACT This study aimed to select promising F2RC1 populations of saladette-type dwarf tomato plants for the development of breeding lines based on agronomic characteristics, fruit quality, and whitefly resistance. The experimental design was randomized blocks containing 13 treatments (10 F2RC1 populations of dwarf tomato plants, both parents, and a commercial hybrid) with four replicates. The evaluations were performed included weight, length, diameter, shape, pulp thickness, number of locules, soluble solids, β-carotene, and lycopene concentration of the fruit; plant internode length; acylsugars concentration; and number of whitefly eggs, nymphs, and adults on the leaflets. The data were analyzed using ANOVA, selection indices, and multivariate analysis. The first backcross increased the agronomic characteristics of the populations in relation to the donor parent, especially for fruit weight (169.1%), fruit length (26.1%), and fruit diameter (16.6%). The UFU SDi 7, UFU SDi 9, and UFU-SDi 17 populations were selected using two selection indices and were therefore considered promising.

Abstract The interaction between animal movement and roads is pervasive, but little is known of the effects of the land-use patterns in roadside landscapes on roadkill events. Here, we compared wildlife roadkill along two road stretches that cross landscapes with different land-use patterns, including the presence of protected areas in Central Brazil. Sampling was conducted in 2017 and 2018 in two seasons (dry and rainy). We expected roadkill events to be more frequent bordering the protected area. Roadkill occurred more frequently in the rainy season in the unprotected landscape. Birds were most frequently recorded in the unprotected (44%, n = 76) than in the protected landscape (37%, n = 48). The least recorded group in the unprotected landscape was Squamata (11%, n = 18), while mammals were less detected in the protected landscape (14%, n = 18). Classes ‘agriculture’ and ‘savanna’ were related to amphibian roadkill numbers. For Squamata, we observed the effect of the presence of forests in the protected landscape. Bird roadkill was affected by protection level, while the presence of pasture and the level of protection explained mammal roadkill. Differences in roadkill patterns reinforce the need for long-term management of this source of mortality for the Cerrado fauna.

RESUMO Nós relatamos a ocorrência do lagarto Gymnophthalmus underwoodi no município de Belém, estado do Pará, Brasil. Este é o primeiro registro ao sul do Rio Amazonas, provavelmente como resultado de uma introdução acidental por navios que atracam em Belém, o mesmo caminho sugerido para a introdução de outra espécie exótica de lagarto recentemente encontrada na cidade. Nós também determinamos a identidade de alguns espécimes de Gymnophthalmus dos estados do Amapá e Pará, através de dados morfológicos externos e moleculares, confirmando que, até o momento, G. vanzoi é o único Gymnophthalmus ocorrendo nos enclaves de savana desses estados. Por fim, nós fornecemos um novo mapa de distribuição para as espécies de Gymnophthalmus, incluindo o novo registro de ocorrência de G. underwoodi para o estado do Pará, onde ela pode ser considerada como uma espécie invasiva.

ABSTRACT We report the occurrence of the lizard Gymnophthalmus underwoodi in the municipality of Belém, state of Pará, Brazil. This is the first record of that species south of the Amazonas River, probably because of an accidental introduction by ships that dock in Belém, the same pathway suggested for the recent introduction of another species of exotic lizard recently recorded in the city. We also determined the identity of some specimens of Gymnophthalmus from the states of Amapá and Pará through external morphology and molecular data, confirming that, until now, G. vanzoi is the only Gymnophthalmus occurring in the savanna enclaves of those states. Finally, we provide a new distribution map for the species of Gymnophthalmus, including the new occurrence record for G. underwoodi for the state of Pará, where it can be considered as an invasive species.

RESUMO As normas da liturgia foram constantemente compreendidas a partir de um horizonte jurídico englobado pelo direito canônico positivo, e isso sem necessariamente considerar o enraizamento das normas na complexa realidade humana. A partir de alguns estudos feitos por C. Lévi-Strauss, J. Henriot, E. Fink, R. Caillois, C. Duflo, E. Ortigues, R. Guardini, H. Küng, L-M. Chauvet, e M. Brulin sobre o jogo e o símbolo, este artigo busca mostrar que, ultrapassando os limites estabelecidos pelo direito, a regra da liturgia é profundamente enraizada em princípios partilhados ao mesmo tempo pelas ciências sociais e a teologia. A abordagem desta problemática, além de contribuir na reflexão sobre o fundamento do caráter jurídico das práticas litúrgicas, pode ajudar a reconhecer a vida litúrgica como fonte de suas normas.

ABSTRACT The norms of liturgy have often been understood within a judicial horizon, bounded by positive canonical law, without necessarily taking into consideration the grounding of these norms in the complexity of human reality. Based on studies conducted by C. Lévi-Strauss, J. Henriot, E. Fink, R. Caillois, C. Duflo, E. Ortigues, R. Guardini, H. Küng, L.-M. Chauvet and M. Brulin on the play and the symbol, the present article seeks to show that, beyond the bounds established by law, the rule of liturgy is deeply rooted in the principles shared by both the social sciences and theology. Addressing this problem, in addition to contributing to the reflection on the basis of the judicial character of liturgical practices, can help to recognize liturgical life as the source of its norms.

Resumo Introdução: A estimulação não-invasiva tem sido amplamente utilizada nos últimos 30 anos no estudo e no tratamento de um grande número de doenças neurológicas, incluindo distúrbios do movimento. Objetivos: Nesta revisão crítica, discutimos o embasamento científico do uso da estimulação não-invasiva em distúrbios do movimento e as evidências científicas dos principais ensaios clínicos realizados. Métodos: Um grupo de especialistas realizou uma revisão crítica abrangente da literatura a fim de analisar as principais aplicações da estimulação magnética transcraniana (EMT) e da estimulação transcraniana por corrente contínua (ETCC) em distúrbios do movimento. As classes de evidência e de recomendação foram descritas para cada doença. Resultados: Apesar da grande variabilidade da metodologia e baixo efeito clínico, a EMT é provavelmente eficaz para o tratamento dos sintomas motores e da depressão na doença de Parkinson. A eficácia em outros distúrbios do movimento ainda é incerta. A EMT é possivelmente eficaz para o tratamento da distonia focal da mão, do tremor essencial e da ataxia cerebelar. No entanto, é provavelmente ineficaz na redução dos tiques na síndrome de Tourette. Finalmente, a ETCC é provavelmente eficaz na melhora da marcha na doença de Parkinson. Conclusões: As evidências até o momento sugerem que a estimulação não-invasiva pode ser benéfica para o alívio de alguns sintomas em determinados distúrbios do movimento como a doença de Parkinson, o tremor essencial, a distonia e a ataxia. Os protocolos de aplicação e paradigmas de estimulação ainda precisam ser investigados em ensaios clínicos maiores, assim como os seus efeitos a longo prazo.

Abstract Background: Noninvasive stimulation has been widely used in the past 30 years to study and treat a large number of neurological diseases, including movement disorders. Objective: In this critical review, we illustrate the rationale for use of these techniques in movement disorders and summarize the best medical evidence based on the main clinical trials performed to date. Methods: A nationally representative group of experts performed a comprehensive review of the literature in order to analyze the key clinical decision-making factors driving transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) in movement disorders. Classes of evidence and recommendations were described for each disease. Results: Despite unavoidable heterogeneities and low effect size, TMS is likely to be effective for treating motor symptoms and depression in Parkinson’s disease (PD). The efficacy in other movement disorders is unclear. TMS is possibly effective for focal hand dystonia, essential tremor and cerebellar ataxia. Additionally, it is likely to be ineffective in reducing tics in Tourette syndrome. Lastly, tDCS is likely to be effective in improving gait in PD. Conclusions: There is encouraging evidence for the use of noninvasive stimulation on a subset of symptoms in selected movement disorders, although the means to optimize protocols for improving positive outcomes in routine clinical practice remain undetermined. Similarly, the best stimulation paradigms and responder profile need to be investigated in large clinical trials with established therapeutic and assessment paradigms that could also allow genuine long-term benefits to be determined.

RESUMO O objetivo do estudo foi analisar as tarefas de treinamento técnico-tático de equipes femininas de handebol sub-16. Neste estudo descritivo, quantitativo e observacional, dois treinadores e 27 atletas da categoria cadete (U-16) de duas equipes de handebol feminino do estado de Santa Catarina (Brasil) foram investigados. Os dados foram coletados por meio de observação sistemática e indireta (filmagem) de 36 sessões de treinamento, transcritas e analisadas no Sistema Integral de Análise de Treinamento (SIATE). O tratamento dos dados foi baseado em estatística descritiva (frequência) e inferencial (modelagem hierárquica em vários níveis), utilizando o software SPSS 23.0 e o programa R. Nas 336 tarefas analisadas, observou-se que as sessões priorizaram jogos e competição como forma de treinamento e conduta tático-técnica como o tipo de conteúdo. Os treinadores usaram um modelo ondulador na estruturação das tarefas nos microciclos investigados, ambas as equipes priorizando o uso de situações de treinamento semelhantes às exigências das partidas oficiais de handebol

ABSTRACT The aim of the study was to analyze the technical-tactical training tasks of U-16 female handball teams. In this descriptive, quantitative and observational study, two coaches and 27 athletes from the cadet (U-16) category of two women's handball teams from the state of Santa Catarina (Brazil) were investigated. The data were collected through systematic and indirect observation (filming) of 36 training sessions, transcribed and analyzed from the Integral System for the Analysis of Training (SIATE). The data treatment was based on descriptive (frequency) and inferential statistics (hierarchical-multilevel modeling), using SPSS 23.0 software and program R. In the 336 tasks analyzed, it was observed that the sessions prioritized games and competition as means of training and tactical-technical conduct as the content type. The coaches used an undulatory model in the structuring of the tasks in the investigated microcycles, both teams prioritizing the use of training situations similar to the requirements of official handball matches.
