Efeito agudo de dois modelos de treinamento intervalado de alta intensidade sobre a carga interna em atletas de futsal feminino

TCC (Graduação) - Universidade Federal de Santa Catarina. Centro de Desportos. Educação Física - Bacharelado.A identificação das exigências fisiológicas impostas aos jogadores de futsal durante as partidas é fundamental para a formulação das estratégias da equipe durante a temporada, pois contribuem de forma decisiva para que a comissão técnica elabore um programa de treinamento apropriado e adaptado às necessidades específicas do esporte. Contudo, apesar da aplicação usual do treinamento intervalado de alta intensidade (TIAI) na periodização de atletas de diferentes modalidades, é possível notar ainda, a ausência de informações sobre a análise dos efeitos agudos sobre as variáveis de carga interna, como percepção subjetiva de esforço (PSE) e frequência cardíaca (FC) e Lactato sanguíneo ([Lac]), principalmente no que se refere ao futsal feminino. Nessa perspectiva, o objetivo desse estudo foi analisar o efeito agudo de dois modelos de treinamento intervalado de alta intensidade (TIAI) sobre os valores de carga interna em atletas de futsal feminino. O presente estudo caracteriza-se sendo aplicado, de abordagem quantitativa e empírica. Treze jogadoras adultas (21,2±2,8 anos; 60,3±7,6 kg; 1,63±0,06 cm; 20,6%±5,7 gordura) foram submetidas a quatro sessões experimentais: 1) avaliação antropométrica e teste incremental em esteira rolante (TIER); 2) Futsal Intermittent Endurance Test (FIET); 3) Maximal Shuttle Run Test (40-m MST); 4) divididas em dois grupos, completaram dois modelos de TIAI consistindo em 8 séries similares em relação esforço:pausa (1:1), distância relativa (m.min-1) e intensidade de corrida (100% Pico Velocidade), mas com número de mudanças de direção distintos (TIAI7,5x7,5=1 vs. TIAI15x15=3). Amostras de lactato sanguíneo [Lac], frequência cardíaca (FC) e percepção subjetiva de esforço (PSE) foram coletados. Não foram encontradas diferenças entre as médias de FC e PSE durante TIAI entre os grupos (p0,05) em ambos os grupos. Valores de [Lac] foram superiores no TIAI7,5x7,5 comparado ao TIAI15x15 na série 1 (F(2,28)=2,234; p=0,026), além disso, a análise de inferência demonstrou valores muito provavelmente maiores na série 1 (98/1/1) e provavelmente na série 2 (93/5/2) ambos com grande effect size (ES=1,31; ES=0,84), respectivamente. Com base nos resultados obtidos, conclui-se que os ambos os modelos de TIAI são capazes de promover mudanças na aptidão aeróbia quanto anaeróbia em jogadoras de futsal em uma mesma proposta de treinamento.Identifying the physiological requirements imposed on futsal players during matches is fundamental for the formulation of team strategies during the season as they contribute decisively to the technical committee's designing an appropriate training program tailored to the specific needs of the sport. However, despite the usual application of high intensity interval training (TIAI) in the periodization of athletes of different modalities, it is possible to note the lack of information on the analysis of the acute effects on the variables of internal load, such as subjective perception of effort (PSE) and heart rate (HR) and blood lactate ([LAC]), especially with regard to female futsal. In this perspective, the aim of the present study was to analyze the effects of two high-intensity interval training models (HIIT) on internal load in female futsal athletes. The present study is characterized by being applied, with a quantitative and empirical approach. Thirteen female players (21,2±2,8 years; 60,3±7,6 kg; 1,63±0,06 cm; 20,6%±5,7 body fat) were submitted to four experimental sessions: 1) anthropometric measures and incremental test on a treadmill (ITT); 2) Futsal Intermittent Endurance Test (FIET); 3) Maximal Shuttle Run Test (40-m MST); 4) Divided into two groups, the athletes completed two HIIT models consisted of eight series similiar in relation to rest ration (1:1), relative distances (m.min-1) and running intensity (100% Peak Velocity), but different number of direction changes (TIAI7,5x7,5=1 vs. TIAI15x15=3). Samples of blood lactate [LAC], heart rate (HR) and rating of perceived exertion (RPE) were collected. No differences were found between the means of HR and PSE during TIAI between the groups (p 0,05) in both groups. Higher [LAC] values were showed in TIAI7,5x7,5 than TIAI15x15 in serie 1 (F(2,28)=2,234; p=0,026), in addition, magnitude based inference analysis reported values very likely higher in series 1 (98/1/1) and likely in series 2 (93/5/2) with large effect size in both cases (ES=1,31; ES=0,84) respectively. Based on the results of the present study, it can be concluded that both HIIT models are able to promote changes in aerobic and anaerobic fitness on futsal players in the same training proposal

Estimating Listeria monocytogenes growth in ready-to-eat chicken salad using a challenge test for quantitative microbial risk assessment

Research Areas: Public, Environmental & Occupational Health ; Mathematics ; Mathematical Methods In Social SciencesCurrently, there is a growing preference for convenience food products, such as ready-toeat (RTE) foods, associated with long refrigerated shelf-lives, not requiring a heat treatment prior to consumption. Because Listeria monocytogenes is able to grow at refrigeration temperatures, inconsistent temperatures during production, distribution, and at consumer’s household may allow for the pathogen to thrive, reaching unsafe limits. L. monocytogenes is the causative agent of listeriosis, a rare but severe human illness, with high fatality rates, transmitted almost exclusively by food consumption. With the aim of assessing the quantitative microbial risk of L. monocytogenes in RTE chicken salads, a challenge test was performed. Salads were inoculated with a three-strain mixture of cold-adapted L. monocytogenes and stored at 4, 12, and 16 °C for eight days. Results revealed that the salad was able to support L. monocytogenes’ growth, even at refrigeration temperatures. The Baranyi primary model was fitted to microbiological data to estimate the pathogen’s growth kinetic parameters. Temperature effect on the maximum specific growth rate (μmax) was modeled using a square-root-type model. Storage temperature significantly influenced μmax of L. monocytogenes (p < 0.05). These predicted growth models for L. monocytogenes were subsequently used to develop a quantitative microbial risk assessment, estimating a median number of 0.00008726 listeriosis cases per year linked to the consumption of these RTE salads. Sensitivity analysis considering different time–temperature scenarios indicated a very low median risk per portion (<−7 log), even if the assessed RTE chicken salad was kept in abuse storage conditions.info:eu-repo/semantics/publishedVersio

Burden of disease estimation based on Escherichia coli quantification in ready-to-eat meals served in Portuguese institutional canteens

Research Areas: Food Science & TechnologyShiga toxin-producing E. coli (STEC), enterotoxigenic E. coli (ETEC) and enteropathogenic E. coli (EPEC) are associated with the onset of gastroenteritis with different severities, and STEC has been associated with other sequelae, such as hemolytic uremic syndrome and end stage renal disease. The main goal of this study was to estimate the annual foodborne burden of disease associated with STEC, ETEC and EPEC infection based on E. coli quantification results obtained in the routine analysis of ready-to-eat meals served in institutional canteens from 2018 to 2019. A stochastic Quantitative Microbial Risk Assessment (QMRA) model was used to estimate the expected number of cases per health outcome and Disability Adjusted Life Years (DALYs). Assuming a daily consumption of a whole meal portion (450 g), the estimated burden was of 4.2 x 10-3 DALYs/person/year for STEC infection, 2.82 x 10-4 DALYs/person/year for ETEC infection and 7.91 x 10-6 DALYs/person/year for EPEC infection. Additionally, using the Sobol method, the sensitivity analysis revealed that the factors with higher influence on the final output (DALYs) were the pathotype's prevalence for the STEC model, the number of people exposed to the hazard for the ETEC model and E. coli concentrations for the EPEC modelinfo:eu-repo/semantics/publishedVersio

Molecular survey of vector-borne diseases in two groups of domestic dogs from Lisbon, Portugal

Research Areas: Parasitology ; Tropical MedicineABSTRACT - Background: Canine vector-borne diseases (CVBDs) are caused by a wide range of pathogens transmitted by arthropods. They have been an issue of growing importance in recent years; however, there is limited information about the vector-borne pathogens circulating in Portugal. The aim of the present study was to detect canine vector-borne bacteria and protozoa of veterinary and zoonotic importance using molecular methods. Methods: One hundred and forty-two dogs from Lisbon, southern Portugal, were tested: 48 dogs from a veterinary hospital clinically suspected of vector-borne diseases and 94 apparently healthy dogs from shelters. Anaplasma spp./Ehrlichia spp., Babesia/Theileria spp., Hepatozoon spp., and Mycoplasma spp. infections were detected by PCR from blood samples and examined under light microscopy. Other information including clinical status and diagnostic test results were collected for each animal. Results: Infections were detected by PCR in 48 (33.80%) dogs. Single infections were found in 35 dogs (24.64%), and co-infections were found in 13 (9.15%) dogs. Twenty-nine (20.42%) dogs were positive for Hepatozoon spp., 15 (10.56%) for Mycoplasma spp., 11 (7.75%) for Anaplasma spp./Ehrlichia spp., and six (4.21%) for Babesia spp. DNA sequencing was used to identify Babesia vogeli (2.81%), Babesia canis (1.40%), Hepatozoon canis (20.42%), Mycoplasma haematoparvum (2.11%), Mycoplasma haemocanis (8.45%), Anaplasma platys (7.04%), and Ehrlichia canis (0.70%). Conclusions: This is the frst molecular identifcation of B. canis and M. haematoparvum in dogs from southern Portugal. This study highlights the importance of molecular methods to identify CVBD pathogens in endemic areas and helps to guide the clinical approach of veterinarians in practice.info:eu-repo/semantics/publishedVersio

Pollen morphology of the endemic genera of the Madeira archipelago, Portugal

ABSTRACT: This study presents the first palynological characterisation of the five endemic plant genera of the Madeira archipelago: Chamaemeles Lindl, Melanoselinum Hoffm., Monizia Lowe, Musschia Dumort and Sinapidendron Lowe. Pollen grain morphology of ten endemic species was studied using light and scanning electron microscopy techniques. The size and shape of pollen grains, the polar axis, the equatorial diameter, and the exine ornamentation were measured and described. We found that the pollen grains of the five endemic genera are all medium-size monads. The close relative apiaceous Melanoselinum and Monizia differ in polar (P) and equatorial (E) diameter size and exine ornamentation while Sinapidendron species show differences in P, E, and P/E ratios. The pollen grains of the two Musschia species are very similar to each other, but differ in morphology and ornamentation from the Macaronesian endemic bellflowers Azorina vidalii and Canarina canariensis. This study unveiled differences between the endemic taxa and with their close related species, thus providing support to previous taxonomic findings.info:eu-repo/semantics/publishedVersio

Veterinary syndromic surveillance using swine production data for farm health management and early disease detection

Research Areas: Veterinary SciencesThe use of syndromic surveillance (SyS) has grown in animal health since the 2010s, but the use of production data has been underexplored due to methodological and practical challenges. This paper aimed to tackle some of those challenges by developing a SyS system using production data routinely collected in pig breeding farms. Health-related indicators were created from the recorded data, and two different time-series types emerged: the weekly counts of events traditionally used in SyS; and continuous time-series, where every new event is a new observation, and grouping by time-unit is not applied. Exponentially Weighted Moving Average (EWMA) and Shewhart control charts were used for temporal aberration detection, using three detection limits to create a “severity” score. The system performance was evaluated using simulated outbreaks of porcine respiratory and reproduction syndrome (PRRS) as a disease introduction scenario. The system proved capable of providing early detection of unexpected trends, serving as a useful health and management decision support tool for farmers. Further research is needed to combine results of monitoring multiple parallel time-series into an overall assessment of the risk of reproduction failure.info:eu-repo/semantics/publishedVersio
