Aptidão cardiorrespiratória e comportamento da frequência cardíaca em situações semelhantes ao jogo em atletas profissionais de futsal

O futsal é uma modalidade intermitente de alta intensidade que requer treinamento por meio de atividades situacionais envolvendo os metabolismos aeróbio e anaeróbio. A frequência cardíaca (FC) pode ser considerada um grande indicador de fadiga pensando nas características do futsal e em sua relação com a aptidão cardiorrespiratória (ACR). O objetivo do presente estudo foi relacionar a ACR com o comportamento da FC em situações semelhantes às de jogo em atletas profissionais de futsal. Trata-se de um estudo transversal desenvolvido com 20 atletas (21,3 ± 5,8 anos) de uma equipe profissional de futsal (série ouro) do estado do Paraná.  Foram realizadas medidas antropométricas, teste de ACR, análise da FC em jogo simulado e análise dos dados por meio de estatística descritiva e correlação parcial de Pearson. A análise estatística não encontrou diferença significativa entre FC e consumo máximo de oxigênio (VO2 max) (r=0,15). Em relação ao comportamento da FC no jogo simulado, não foram encontradas diferenças estatísticas em nenhuma zona percentual da FC entre as diferentes posições de jogo. Situações expressas durante uma partida de futsal demonstraram que a FC não está associada à ACR, uma vez que os jogadores que apresentam melhor ACR nem sempre conseguem manter valores de FC inferiores em quadra, além disso, fixos, alas e pivôs não apresentaram diferenças estatísticas em relação ao comportamento da FC durante o jogo

Effects of different order of combined training on functional capacity, blood pressure, and body composition in women from 53 to 79 years old

OBJECTIVE: To assess the effects of order of resistance training (RT) and high-intensity interval training (HIIT) on functional capacity, blood pressure, and body composition in middle-aged and older women. METHODS: Twenty-two participants were randomly assigned to one of two groups: RT followed by HIIT (RT-HIIT, n = 10, mean age 64.5 ± 7.9 years) or HIIT followed by RT (HIIT-RT, n = 10, mean age 59.32 ± 4.44 years). Both groups trained twice a week for 8 weeks. RT was composed of 7 exercises for the upper and lower body. HIIT was composed of alternate pairings of high-intensity (&gt; 85% of maximum heart rate [MHR]) and moderate-intensity (60% MHR) running. RESULTS: A time effect was found for upper-body muscle endurance (HIIT-RT = +9.43%; RT-HIIT = +6.16%), agility and dynamic balance (HIIT-RT = -5.96%; RT-HIIT = -8.57%), and cardiorespiratory fitness (HIIT-RT = +5.14%; RT-HIIT = +6.13%), with no difference between groups. Body composition and blood pressure did not change throughout the investigation for either group. CONCLUSION: Eight weeks of a combined HIIT and RT exercise program improved functional capacity of middle-aged and older women without altering blood pressure and body composition, regardless of the order of exercises.</p

Changes in the daily routine and life perceptions of older adults due to the coronavirus disease 2019 (COVID-19) pandemic

OBJECTIVE: This study aimed to analyze changes in the daily routine and life perceptions of older adults due to the coronavirus disease 2019 pandemic. METHODS: This is a cross-sectional study conducted with 338 older adults (93 men and 238 women) residing in southern Brazil. An online questionnaire consisting of 20 questions was created using the Google Forms platform and was distributed to older adults (&gt; 60 years of age) during the isolation period caused by the coronavirus disease pandemic. Data analysis was conducted through Student’s-t and χ2 tests. RESULTS: Our results showed a significant association between social isolation and sex (p &lt; 0.01), revealing that women experienced higher levels of social isolation than men. We observed that 82.21% of the older adults participating in this study reported changes in their social routines during the pandemic. CONCLUSIONS: During this period of extended social isolation, women reported more negative effects than men.</p

Análise da composição corporal e de níveis de aptidão física de escolares praticantes de Futsal em relação aos índices sugeridos pelo projeto esporte Brasil (PROESP-BR) em fase preparatória para competições escolares

In Brazil, Futsal, when compared to other collective sports, is one of the most practiced sports in the school environment, mainly by adolescents, however, during the game several physical and motor actions require that its practitioners have a certain level of physical fitness. Therefore, the present study had as objective to analyze the body composition and the physical fitness levels of Futsal students in a public school in the Municipality of Neópolis-SE in relation to the indexes suggested by the Brazilian Sports Project (PROESP-BR) comparing them with other studies that also analyzed the levels of physical fitness of young futsal practitioners. The sample consisted of 18 male adolescents between 12 and 14 years old (13 ± 0.8 years old) enrolled in a public school in the city of Neópolis / SE. In order to obtain the data, the battery of measures and tests related to PROESP-BR was used. Weight and height were collected to calculate BMI. For the physical fitness variables, BMI and flexibility were analyzed. The results were analyzed and compared with the data provided by PROESP-BR. The data were also compared to studies that also analyzed the physical fitness levels of young futsal practitioners. It is concluded that during a preparation of futsal school teams, even if the students / athletes already have good levels of the health-related physical fitness components, the systematized training of sports modalities offers the possibility for these levels to be optimized, the quality of life and the well-being of the practitioners.No Brasil, o Futsal quando comparado com outras modalidades esportivas coletivas, é um dos esportes mais praticados no âmbito escolar, principalmente pelos adolescentes, porém, durante a partida diversas ações físicas e motoras exigem que os seus praticantes tenham um certo nível de aptidão física. Diante disto, o presente estudo teve como objetivo analisar a composição corporal e os níveis de aptidão física de escolares praticantes de Futsal em relação aos índices sugeridos pelo Projeto Esportivo Brasil (PROESP-BR) comparando-os com outros estudos que também analisaram os níveis de aptidão física de jovens praticantes de futsal. A amostra foi composta por 18 adolescentes do sexo masculino com idade entre 12 e 14 anos (13 ± 0,8 anos) matriculados numa escola pública da cidade de Neópolis-SE. Para a obtenção dos dados foi utilizada a bateria de medidas e testes referentes ao PROESP-BR. Foram coletados peso e altura para cálculo do IMC. Para as variáveis da aptidão física foram analisadas o IMC e a flexibilidade. Os resultados foram analisados e comparados com os dados oferecidos pelo PROESP-BR. Os dados também foram comparados a estudos que também analisaram os níveis de aptidão física de jovens praticantes de futsal.  Conclui-se que durante uma preparação de equipes escolares de futsal, mesmo que os alunos/atletas já estejam com bons níveis dos componentes da aptidão física relacionada a saúde, os treinamentos sistematizados de modalidades esportivas oferecem a possibilidade para que estes níveis sejam otimizados, elevando a qualidade de vida e o bem-estar dos praticantes.

Reconstruction of interactions in the ProtoDUNE-SP detector with Pandora

International audienceThe Pandora Software Development Kit and algorithm libraries provide pattern-recognition logic essential to the reconstruction of particle interactions in liquid argon time projection chamber detectors. Pandora is the primary event reconstruction software used at ProtoDUNE-SP, a prototype for the Deep Underground Neutrino Experiment far detector. ProtoDUNE-SP, located at CERN, is exposed to a charged-particle test beam. This paper gives an overview of the Pandora reconstruction algorithms and how they have been tailored for use at ProtoDUNE-SP. In complex events with numerous cosmic-ray and beam background particles, the simulated reconstruction and identification efficiency for triggered test-beam particles is above 80% for the majority of particle type and beam momentum combinations. Specifically, simulated 1 GeV/$c$ charged pions and protons are correctly reconstructed and identified with efficiencies of 86.1$\pm0.6$% and 84.1$\pm0.6$%, respectively. The efficiencies measured for test-beam data are shown to be within 5% of those predicted by the simulation
