Contra o comunismo demoníaco: o apoio evangélico ao regime militar brasileiro e seu paralelo com o endosso da direita cristã ao governo Bolsonaro
Authors: Lacerda Marina
Published: May 2022

Resumo: Desde 2015, evidenciou-se na Câmara dos Deputados uma coalizão entre direita cristã e bancada da segurança. A eleição de Jair Bolsonaro à Presidência em 2018 foi considerada, por alguns autores, um reavivamento de 1964. Dentre os principais integrantes de seu bloco de sustentação estiveram os evangélicos. A aproximação é inédita? Mais precisamente: o posicionamento das lideranças religiosas reformadas e pentecostais sobre o regime militar (1964-1985) se relaciona às posturas políticas da direita cristã hoje? Pretendendo adentrar nessa questão, o artigo revisa a literatura sobre o tema e conclui fazendo paralelos entre o processo iniciado com o golpe contra Goulart e o da segunda década do século XXI, identificando a retórica anticomunista como o traço de continuidade entre os diferentes momentos históricos.
Las iglesias le dan continente al migrante: igrejas, religiosidades e venezuelanos/as no norte do Brasil
Authors: Vasconcelos Iana dos Santos
Published: May 2022

Resumo: O artigo destaca o lugar da religiosidade nas relações entre migrantes venezuelanos/as e Igrejas cristãs católica e não católicas em Boa Vista (RR) e Manaus (AM). A intesificação do deslocamento venezuelano pelo Brasil setentrional desde 2015 mobilizou dezenas de instituições de índole religiosa para atuar no acolhimento aos/às migrantes. Modos de acolher e ser acolhido se interseccionam com as variadas religiosidades de quem dá e de quem recebe. O predomínio dos grupos religiosos na prestação de serviços “humanitários” no Brasil reflete uma tendência global de terceirização das políticas governamentais. Igrejas e comunidade de fiéis atuam nas brechas deixadas pela não incidência estatal. Contraditoriamente, de um lado reividicam ações de governo e, por outro, fortalecem práticas neoliberais de acolhimento.
A transnacionalidade terapêutica antroposófica Brasil-Suíça: uma Bildung decolonial?
Authors: Bastos Raquel Littério de , Mercante Marcelo Simão , Pereira Pedro Paulo Gomes
Published: May 2022

Resumo: Mais da metade das Práticas Integrativas e Complementares (PICs) oferecidas no SUS são estrangeiras. Importadas de outros continentes, elas foram moldadas em diferentes culturas com distintas concepções de corpo, saúde, doença e cura. No fluxo dessas terapias, a Antroposofia apresenta uma transnacionalidade que, a priori, absorvia as práticas terapêuticas europeias, adaptando-as às questões culturais e climáticas, mas também produzia e exportava terapias originalmente brasileiras para a Europa, em um movimento contrário, do Sul para o Norte Global. Promotora de uma bildung nos indivíduos, a Antroposofia busca um forjar a si mesmo como um mote terapêutico. Este artigo reflete sobre essa transnacionalidade terapêutica portadora de um projeto de bildung e se este seria decolonial, rompendo com a lógica e o prestígio europeu.
As duas faces evangélicas do espiritismo brasileiro
Authors: Souza André Ricardo de , Torres Natália Cannizza
Published: May 2022

Resumo: Atrás do catolicismo, o segmento evangélico constitui o segundo maior do país, prosseguindo em grande crescimento devido ao pentecostalismo. Com tamanho dez vezes menor, mas estando também em expansão, o espiritismo kardecista ocupa a terceira colocação, sendo caracterizado, atualmente e em boa medida, por um conjunto de percepções, valores e práticas próprias dos evangélicos pentecostais. Essas abarcam, por um lado, a valorização da Bíblia, sobremaneira o Novo Testamento, que é chamado nesse meio de “Estudos do Evangelho”, ressaltando a identidade religiosa e cristã do espiritismo. E, por outro, envolvem um controverso ativismo político-ideológico conservador, algo que tem consequências significativas. Este artigo, decorrente de pesquisa de campo e de análise dirigida à circulação de notícias relevantes, discute tais semelhanças específicas entre o espiritismo e o pentecostalismo.
Schumpeterian competition and its policy implications: The Latin American case
Authors: ARAÚJO JR. JOSÉ TAVARES DE
Published: May 2022

ABSTRACT Using the Schumpeterian notion of Creative Destruction, this paper discusses the role of antitrust in the process of economic reform and illustrates with the Latin American case. According to that notion, competition is a process wherein firms strive to survive under an evolving set of rules that engenders winners and losers. The main instrument that allows firms to be ahead of their competitors is the introduction of informational asymmetries that may result either from technological innovation, rent seeking or organized crime. To the public authorities this process implies two challenges. The former is to identify the situations that require intervention and the latter is to ensure that innovation will be the only available instrument for creating in- formational asymmetries.

Food consumption markers and associated factors in Brazil: distribution and evolution, Brazilian National Health Survey, 2013 and 2019
Authors: Santin Fernanda , Gabe Kamila Tiemann , Levy Renata Bertazzi , Jaime Patricia Constante
Published: May 2022

This study objective was to describe the distribution of food consumption markers in Brazil per sociodemographic characteristics and its evolution from 2013 to 2019. Healthy food consumption markers (regular consumption of beans, fruits, vegetables, and fish, recommended consumption of red meat, and never replacing meals with snacks) and unhealthy food consumption markers (regular consumption of sweetened beverages and confectionery and excessive salt intake) were studied for adult participants of the Brazilian National Health Survey. The prevalence of food consumption markers was estimated according to sociodemographic characteristics and compared to data of 2013 and 2019. Most of the population regularly consumes beans, fruits, and vegetables, they also follows the recommendation to limit red meat consumption, and never replaces meals with snacks. The percentage of people who regularly consume sweetened beverages and perceive their salt intake as excessive is relatively low. The distribution of food consumption markers was associated with sex, age, income, race/skin color, area of dwelling, and schooling level. From 2013 to 2019, the prevalence of most food consumption markers declined, except for the regular consumption of fruits and recommended consumption of red meat, that increased 8.5% and 18.5%, respectively, and the regular consumption of vegetables, which did not vary. Healthy and unhealthy food consumption markers should be monitored to evaluate the effect of healthy eating policies implemented in the country.
Score of ultra-processed food consumption and its association with sociodemographic factors in the Brazilian National Health Survey, 2019
Authors: Costa Caroline dos Santos , Steele Eurídice Martínez , Faria Franciane Rocha de , Monteiro Carlos Augusto
Published: May 2022

This is a cross-sectional population-based study that describes the score of ultra-processed food consumption, applied in the Brazilian National Health Survey performed in 2019, and its association with sociodemographic factors in Brazilian adults (18 years or older). The score of ultra-processed food consumption was calculated by adding up the positive answers about the consumption on the previous day of 10 subgroups of ultra-processed foods frequently consumed in Brazil. The distribution of the score in the population was presented as a count. Poisson regression models were used to evaluate the crude and adjusted associations of scores equal to or higher than five subgroups of ultra-processed foods with urban/rural area, geographic region, sex, age group, schooling level, and wealth index. About 15% of the Brazilian adults reached scores equal to or higher than five. After adjustment for confounders, the prevalence of consuming five or more subgroups of ultra-processed foods decreased linearly with age, increased linearly with wealth quintiles and it was higher in urban areas, in the Southeast and South regions (compared to the others) and in men. Public policies that reduce the consumption of ultra-processed foods with emphasis on strata of the population at the greatest risk are essential and monitoring the score of ultra-processed food consumption across studies and populations will be important to assess the success of these policies.

Published: May 2022

The prevalence of diabetes has been growing worldwide. This study aimed to estimate the prevalence of self-reported diabetes in Brazil in 2019, to describe its evolution from 2013, and to evaluate the role of population growth, aging, and other factors in the changes found. The 2019 Brazilian National Health Survey, a nationally representative cross-sectional survey, queried a physician diagnosis of diabetes in a probabilistic multistage cluster sample. The crude prevalence of known diabetes in 2019 was 7.7% (7.4%-8.0%), a 24% relative increase to the prevalence of 2013. Though this increase was greater in men (30%) than women (20%), 2019 prevalence remained higher in women (8.4%) than in men (6.9%). Age-adjusted prevalence was uniformly lower in the North region, and uniformly higher in the Southeast and Central-West regions. In 2019, 12.3 million cases of diabetes were found, a 36.4% increase from the 9.0 million in 2013. Drivers of this rise include increase in size (9.9%) and aging (1.8%) of the Brazilian population, and to all other factors, including increased case-detection and incidence, as well as decreased diabetes mortality (24.7%). Main correlates of greater prevalence - adjusted by the Poisson regression with robust variance - were older age (PR = 27.2, 95%CI: 1.2-42.9 for ≥ 65 years vs. 18-24 years), hypertension (PR = 2.6, 95%CI: 2.4-2.8 vs. normotension), and obesity (PR = 2.3, 95%CI: 2.1-2.5 vs. BMI < 25kg/m2). Those with a complete higher education had a 40% lower prevalence (PR = 0.6; 95%CI: 0.54-0.70 vs. incomplete elementary education). In conclusion, accompanying a worldwide trend, Brazil presents an increasing prevalence of diabetes throughout its regions, posing a huge burden to its population and health systems.

Authors: Lopes Mariana Souza , Freitas Patrícia Pinheiro de , Carvalho Maria Cecília Ramos de , Silva Uriel Moreira , Lopes Aline Cristine Souza
Published: May 2022

We analyzed the impact of the efforts to combat the COVID-19 pandemic on the prices of food sold by a food supply center located in the sixth largest city in Brazil. We examined the percentage change in the prices of 20 types of foods, adjusted by market conditions, using municipal contingency plan stages to compare opening and closing of non-essential services, including bars and restaurants (stage 1: first phase of essential services-only; stage 2: flexibilization; and stage 3: second phase of essential services-only with a “pre-pandemic” period [stage 0]). Log-prices were lower in all contingency stages for leafy greens (variation: 42% to 56%) and vegetables (variation: 28% to 40%). Log-prices of eggs and fruit were 20% and 16% lower during stages 1 and 3, respectively. Strategies to combat the COVID-19 pandemic lowered the prices of eggs, fruit, leafy greens, and vegetables regardless of the market conditions. Accordingly, the supply and demand for fresh and minimally processed foods were affected by the economic crisis and difficulties to access and/or buy perishable foods more often. The impacts of efforts to defeat the pandemic must ensure the human right to adequate food, considering that low prices do not necessarily indicate food security.

Los estudios seroepidemiológicos permiten conocer la distribución indirecta de las enfermedades, detectando marcadores séricos de inmunidad y demostrando infecciones no diagnosticadas en la población general. El objetivo fue estimar la seroprevalencia de anticuerpos contra el SARS-CoV-2, en Córdoba, Argentina, entre diciembre de 2020 y enero de 2021, e identificar factores asociados a la contagiosidad del virus. Se realizó un estudio observacional transversal, de base poblacional, con 3.225 individuos mayores de 2 años, residentes en Córdoba Capital, que fueron seleccionados mediante un diseño de muestreo aleatorio en múltiples etapas, proporcional a la distribución por género, franja etaria y nivel socioeconómico de la población de Córdoba. Las características clínicas, antropometría y comorbilidades se recogieron mediante entrevistas. Se realizó un test serológico cualitativo para la detección de anticuerpos IgG antinucleocápside para SARS-CoV-2 (ARCHITECT, Abbott). La seroprevalencia del SARS-CoV-2 se estimó en la población y por franja de edad, sexo, nivel socioeconómico y presencia de las patologías estudiadas. Las razones de prevalencia (RP) se estimaron usando un modelo de regresión log-binomial. La seropositividad para SARS-CoV-2 fue de 16,68% (IC95%: 15,41-18,01). Tener entre 2 y 18 años, residir en barrios con nivel socioeconómico bajo y la presencia de obesidad, aumentaron la oportunidad de seropositividad (RP = 1,50; IC95%: 1,10-2,04, RP = 1,91; IC95%: 1,34-2,67 y RP = 1,39; IC95%: 1,04-1,85). Los resultados indican que en Córdoba Capital existen atributos diferenciales que aumentan la posibilidad de ser seropositivo para SARS-CoV-2. Esto permite dirigir estrategias de vigilancia epidemiológica para reducir la propagación del virus.

Authors: Sarti Thiago Dias , Almeida Ana Paula Santana Coelho
Published: May 2022

O estudo teve como objetivo analisar a utilização do Programa Nacional Telessaúde Brasil Redes, no âmbito da atenção primária à saúde no Brasil, identificando os fatores relacionados. Estudo transversal a partir da base de dados do segundo ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). A amostra foi composta por 29.756 equipes de saúde que, voluntariamente, aderiram ao programa. As variáveis independentes abrangeram características contextuais (região e porte populacional), da unidade de saúde (tipo, acesso a telefone, banda larga, número de médicos e enfermeiros, consultórios, sala de agentes comunitários de saúde (ACS), sala de reuniões, existência de telessaúde) e da equipe de saúde (apoio institucional). Análises bruta e ajustada por meio de regressão de Poisson avaliaram quais variáveis são associadas ao maior uso do telessaúde. A prevalência de utilização do telessaúde foi de 32,7% no total da amostra e 73,3% entre equipes com o programa implantado. Teleducação foi a modalidade mais frequentemente usada. Maiores prevalências de utilização foram encontradas das regiões Sul e Sudeste, em municípios com até 30 mil habitantes, com telessaúde implantado na unidade, presença de pelo menos um médico e disponibilidade de pelo menos um telefone no estabelecimento. O apoio institucional teve impacto positivo em 40% na prevalência de utilização do telessaúde. Variáveis de estrutura, como Internet e disponibilidade de salas com distintas finalidades, parecem não impactar significativamente a utilização dessas tecnologias, sinalizando que fatores como apoio institucional e a própria implantação do telessaúde na unidade são mais importantes para aumentar a adesão ao programa.

ABSTRACT: This study evaluated the effects of sustained deficit irrigation (SDI) on fruit yield and fruit water quality of dwarf green coconut trees. The experiment was carried out in a commercial orchard located in Camocim, Ceará, Brazil. Four years old coconut trees were irrigated during 29 months, using micro-sprinklers, at irrigation depths equivalent to 55%, 77%, 100% and 131% of crop evapotranspiration (ETc). Green coconut fruits were harvested six months after flower aperture and evaluated for number of fruits per plant, volume of coconut water per fruit and total soluble solids of the coconut water. SDI reduced coconut fruit yield, fruit water volume and coconut water yield. Conversely, SDI increased total soluble solids of the coconut water and irrigation water productivity in terms of fruits and coconut water. Deficit irrigation showed no economic advantage over full irrigation due to the small reduction in irrigation costs compared to the substantial reduction in gross revenue.

Authors: Horoszewicz Elżbieta , Niedziółka Roman
Published: May 2022

ABSTRACT: This study evaluated the meat of lambs from crossbreeding of Polish lowland sheep, heather and rams of the Berrichone du Cher breed (B). The lambs were kept in a medium-intensive feeding system. During fattening, they received haylage and grass hay with the addition of clover, and a mixture of cereal grains with the addition of minerals and vitamins. During the fattening period, all feeds were given at will. The slaughter and cutting of the carcasses were performed in accordance with the technology applicable in the meat industry. In the longissimus lumborum muscle, the content of dry matter, total protein, total fat and ash was determined. In addition, the pH value of 45 minutes and 24 hours after slaughter, as well as the parameters of colour and tenderness of the meat were measured. The content of collagen protein, cholesterol and selected fatty acids was also determined. As a result of the conducted analyzes, the influence of the Berrichone du Cher breed on the improvement of quantitative parameters related to the slaughter value and some parameters related to the physicochemical composition of the hybrid meat was reported.

Published: May 2022

ABSTRACT: Red rice is consumed in whole grain form due to its beneficial nutritional attributes and has become an option for crop diversification. Several factors during plant development can affect the crop’syield. This study evaluated the adaptability and stability of the post-harvest processing of red rice cultivars and compare them with those of white rice cultivars grown in the municipalities of Campos dos Goytacazes, Seropédica, and Pinheiral, RJ, between 2016 and 2018. Two white rice (BRS Esmeralda and IAC 201) and two red rice cultivars (ENA-AR1601 and Virginia) were distributed in the field under randomized block design with five repetitions. Yield, grain class, ingenuity, and whole grain yield were evaluated. The means of these parameters for cultivars in different locations and years were compared by Tukey’s test (P < 0.05). The Eberhart and Russell regression model was used to estimate the adaptability and stability parameters. The grain classification of the cultivars ENA-AR1601 and Virginia was medium and long, respectively. The red rice cultivars ENA-AR 1601 and Virginia showed higher productive performance than the national average. The red rice cultivars and BRS Esmeralda showed highly predictable behavior based on the environmental stimulus. With average values of 62% in the two years evaluated, the red rice cultivars showed excellent processing yield.

ABSTRACT: The objective of this study was to investigate the in vitro action of triiodothyronine (T3) on the chondrogenic differentiation of adipose tissue-derived stem cells (ASCs) of female rats, with different time periods and doses. ASCs were extracted from female Wistar rats and were cultured in chondrogenic medium with and without the presence of T3. Five groups were established: 1) ASCs without T3; and 2,3,4,5) ASCs with 0.01, 1, 100 and 1,000 nM T3, respectively). After 7, 14 and 21 days, cell morphology, chondrogenic matrix formation, and expression of Sox9, aggrecan, collagen II, and collagen X were evaluated. The Student-Newman-Keuls test was used. ASCs showed CD54, CD73, and CD90 before chondrogenic differentiation. The hormone treatment did not alter chondrogenic matrix formation, Sox9 expression at 14 or 21 days, or expression of collagen II or collagen X at any time. However, the 0.01, 1, and 1000 nM T3 doses decreased Sox9 expression at 7 days. In conclusion, chondrogenic differentiation of ASCs of female rats is not influenced by T3.

Published: May 2022

ABSTRACT: This study evaluated the structure of vegetation and the performance of rearing heifers and cull cows in Campos grasslands managed in the rotational stocking method with first-last stocking in the spring-summer period. The treatments were different rest intervals of 402 and 252 degrees-day, which favor the growth of different functional groups of grasses. A completely randomized block design with two treatments and three repetitions was used. The test animals were 24 heifers in the “first” group and 24 cows in the “last” group. In the stratum between tussock grasses, sward heights greater than 0.16 m were predominant in both treatments, it was 1.3 times more frequent in the 402 DD treatment compared to the 252 DD treatment. Average stocking rate was 22% higher in the 252 DD treatment. Although, no differences were observed for the average daily gain of heifers (0.227 kg.day-1) and cows (0.336 kg.day-1) between treatments, the weight gain per area in the experimental period was greater in the 252 DD treatment. Despite the management system with first and last stoking does not provide significant changes in the structure of the pasture, it allowed to achieve satisfactory performance goals in areas of Campos grassland.

Published: May 2022

ABSTRACT: This research determined the engine warm-up time and the number of tests that must be carried out to obtain the performance parameters of a Diesel cycle engine. To this end, an agricultural tractor coupled to an eddy current dynamometer via a power take-off was used. Pure biodiesel (B100) was used as the fuel, and the hourly consumption was determined by means of a flowmeter. Data regarding torque, power, and hourly and specific fuel consumption was collected and analyzed at three engine warm-up times (20, 60, and 100 min). To determine the number of tests, 18 dynamometric tests were carried out to verify which of those presented the smallest experimental error, through the smallest coefficient of variation. No difference was observed in relation to the warm-up time for the analyzed variables, with a time of 20 min being enough to start the engine performance evaluations. In total, four trials were sufficient to assess engine performance and reduce experimental error.

Authors: Sun Zhiwei
Published: May 2022

ABSTRACT Introduction: College students often suffer from injuries in school sports activities. These injuries negatively influence the intellectual and motor learning curve. Thus, it is necessary to investigate and study the sports injuries of college students, their characteristics, and what are the most effective measures to reduce the occurrence of these complications. Objective: Develop an analytical model to verify the causes and solutions in the main injuries in student sports training. Method: The research used a self-administered questionnaire to obtain information about students’ sports injuries. A random number was assigned to each class of each grade in the stratified group sampling method. Classification of causes was done according to the size of the random numbers found. Results: A total of 984 valid questionnaires were obtained (516 male). The injury rate was 53.9%. In all, 278 men and 167 women reported injuries, the injury rate was 35.7%. The injury rate in males in all grades was significantly higher. Conclusion: The results suggest that student awareness work on injury prevention is needed to reduce the incidence of sports complications. Physical education classes can strengthen technical guidance, improve awareness and mindfulness skills in students. It can also help them decrease the psychological stress of exercise, promoting the development of physical and mental health. Evidence Level II; Therapeutic Studies – Investigating the results.

Authors: Zhao Chenzi
Published: May 2022

ABSTRACT Objective: To understand the influence of sports fatigue on plantar pressure distribution of healthy male college students and provide a theoretical basis for improving their awareness of foot health. Methods: Forty-nine ordinary male college students jogged along the 800-meter runway to moderate fatigue. All the subjects took off their shoes and socks and walked naturally with their usual gait. The dynamic plantar pressure of each foot was measured twice in one step. FootscanUSB2 Belgian flat-plate plantar pressure testing system was used for testing. Results: The average dynamic peak plantar pressure was (206.38 44.59) N for boys, and the changes of AA and CB walking speed in the arch did not change significantly. After fatigue, the peak pressure of FM, AA, RH5 in left foot and FM, AA, CB in right foot decreased significantly (P < 0.05, P < 0.01). The peak time of RH and CB in the left foot was significantly shorter than that before fatigue (P < 0.05, P < 0.01), while FMF, AA, C areas had no significant change but tended to be delayed. There were significant differences in peak force-time between boys’ left and right feet except for the fifth metatarsal bone (P < 0.05). There is a significant difference in the peak force-time between the second and fifth toes of the left foot (P< 0.01), and there is a gender difference in the peak force-time between the second metatarsal and the third metatarsal (P < 0.05). Conclusion: Sports fatigue leads to the decrease of physiological functions such as muscle strength of lower limbs, which leads to the corresponding changes in gait stages, plantar pressure distribution parameters, and foot balance. Level of evidence II; Therapeutic studies - investigation of treatment results.

Published: May 2022

ABSTRACT Objective: To explore the influence of leisure sports tourism activities on the health of elderly tourists. Methods: Through investigating the leisure sports tourism activities of some elderly tourists who participated in travel agencies, the health status and quality of life of elderly tourists who participated in leisure sports tourism activities for a long time (exercising group) were compared with those who did not or occasionally participated in physical exercise (non-exercising group), to understand the influence of leisure sports tourism activities on the health of elderly tourists. Results: Regarding the attitude of participating in sports leisure tourism activities, the survey results show that the elderly tourists reached a basic consensus about participating in sports leisure tourism activities. Different types of landscapes have significant differences in improving tourists’ anxiety. The proportion of “very satisfied” in the exercise group was significantly higher than that in the non-exercise group. The duration of the trip has a significant impact on improving tourists’ anxiety. Conclusion: We should strengthen the advertising of leisure sport tourism activities, let more elderly tourists participate in leisure sport tourism activities, strengthen the behavioral guidance of elderly tourists in leisure sport tourism activities, and help them improve their health. Level of evidence II; Therapeutic studies - investigation of treatment results.

Published: May 2022

ABSTRACT Objective: To evaluate the effects of hydrotherapy on post-training recovery of basketball players. Methods: 60 basketball players from the sports representative team were divided equally into test and control group for evaluation according to the Partridge method. The experimental group received hydrotherapy for 15 minutes after intense winter training. Pain degrees in joint flexion and extension, adduction, external rotation, and internal rotation were evaluated. Results: The HL value of blood immediately after 800m hydrotherapy swimming was not significantly different between the experimental group and the control group by t-test (P>0.05). Before treatment, there was no significant difference in the Partridge score between the two groups (P<0.01). The improvement of the Partridge score in the two groups of patients was significantly reduced after treatment (P<0.01), and the improvement of the experimental group was significantly better than that of the control group (P<0.01). Before treatment, there was no significant difference between the two groups (P<0.01). After treatment, it was significantly reduced (P<0.01), but the experimental group’s improvement was significantly better than the control group (P<0.01). Conclusion: The method of introducing hydrotherapy as post-workout swimming has a significant effect on relieving swelling of the brachial and quadriceps muscles.

Published: May 2022

ABSTRACT Objective: To explore the effects of aerobic exercise on the metabolism and physical health of obese college students. Methods: 219 obese college students of different stages were selected by stratified group sampling according to colleges and grades. The effects on physical indices of obese female college students were analyzed by the two-factor variation method after 32 weeks of aerobic exercise training. Results: The experimental group and the control group were significantly improved, and long-term aerobic prescription training was more effective than special education in changing the physical health of obese female college students. After 32 weeks of extreme weight loss training, in the statistical process of 219 valid data, 188 people were found to have lost weight, with the most significant drop reaching 8 kg; BMI decreased in 193 people, and body fat content decreased in 172 people. After 12 weeks of aerobic exercise, the level of cardiopulmonary function of female college students increased. The aerobic exercise prescription designed by the experiment can improve upper and lower limb strength, body flexibility, abdominal muscle strength, and lung function of female college students, which cannot be achieved by diet control alone. Conclusion: Aerobic exercise prescription is an effective means to improve the effect of cardiopulmonary exercise on female college students, and can stimulate the students’ enthusiasm and initiative to exercise independently.

Authors: Zhou Jun
Published: May 2022

ABSTRACT Objective: To analyze the reality of the development of the national active lifestyle, clarify its limitations and countermeasures. Methodology: Official data and consultations in updated bibliographic references were employed for the survey of the main problems with a sedentary lifestyle and their possible solutions. Results: The three urgent problems to be solved in public services are the construction of sports facilities, the organization of regular sports activities, and the establishment of sports organizations. Only a few sports have been promoted in concrete operations. Inadequate physical education and deficient essential public services are also factors affecting national health. Conclusion: Building sports facilities and providing environments with sports equipment are not sufficient against sedentary lifestyles. Relevant policies must be implemented along with massive advertising about the benefits of active lifestyles. Continuous orientation of social workers in community sports groups to promote mass participation is also key to health promotion through sports interventions.

ABSTRACT Introduction: Futsal players must master dribbling in attack and defense positions for a more significant competitive advantage. Optimizing technical control can positively influence decision-making. However, the literature lacks comparative analyses focused on the coverage distance of this technique in sports finals and semifinals. Objective: Analyze the coverage distance of dribbling by futsal players, comparing semifinals and finals results in the Indonesian Futsal League 2021. Methods: A cross-sectional research design method is used in this research. The samples consisted of four games (two semifinal games and two final games) played by four teams (40 players). Movie Maker software was used to cut videos on each dribbling movement, and Kinovea software analyzed dribbling distance. Dribbling-distance differences between the first and second halves of the games were calculated using Wilcoxon’s test. Results: The results show no statistically significant difference in dribbling distances between the first and second halves of the semifinals and finals (p = 0.402 for the semifinals dan p = 0.090 for the finals). Regarding the team analysis, most of the dribbling distances covered in the first and second halves of the semifinals and finals by players from each team were not statistically different, except those covered by Team BTS players in the finals. In all, there were 712 dribbling occurrences in the semifinals and finals, covering 5621.98 meters. The average dribbling distance was 7.90 meters and SD 4.41. Conclusions: The dribbling-distance coverage in the semifinals and finals of the Indonesian Futsal League 2021 was an average of 7.90 meters; no statistically significant difference was found between the finals and semifinals results.Evidence Level II; Therapeutic Studies – Investigating the results.

Published: May 2022

ABSTRACT Introduction: Vitamin E supplementation may protect against exercise-induced muscle damage (EIMD) through possible inhibition of free radical formation and cell membrane stabilization. However, there is no systematic review of this topic. This fact maintains academic stalemates that may have a resolution. Objective: This systematic review with meta-analysis aims to provide a comprehensive literature review on the hypothesis of the benefit of vitamin E supplementation on oxidative stress and muscle damage induced by aerobic exercise. Methods: A random-effects model was used, weighted mean difference (WMD) and 95% confidence interval (CI) were applied to estimate the overall effect. Results: The results revealed a significant effect of vitamin E supplementation on reducing creatine kinase (CK) and lactate dehydrogenase (LDH). In addition, a subgroup analysis resulted in a significant decrease in CK concentrations in trials with immediate and <24 hours post-exercise CK measurement; <1000 at daily vitamin E intake; ≤1 at weekly intake; 1 at six weeks and >6 weeks experimental duration, studies on aerobic exercise and training were part of the crossover study. Conclusion: Vitamin E can be seen as a priority agent for recovery from muscle damage. Evidence Level II; Therapeutic Studies – Investigating the results.
