ABSTRACT The present study aimed to identify and summarize evidence regarding muscle strength (MS) levels in school children and adolescents (≤ 19 years) in Brazil in order to update previously published evidence from the Report Card Brazil project. The systematic search for information was conducted in seven databases, restricted to studies published during the period from January 2018 to December 2019. Thirteen studies were included, which gathered information from 10,135 children and adolescents from seven Brazilian states. Different tests/protocols for assessing MS were identified, however, handgrip strength was the test most adopted in studies (53.8%). The prevalence of children and adolescents with MS levels considered healthy was 29.8%, considering the totality of information, and 27.6% for males and 31.8% for females. Considering full data reviewed by the Report Card Brazil project (data analyzed in this study in addition to those previously published), information regarding the assessment of MS levels in children and adolescents in Brazil came from studies conducted during the period from 2010 to 2019, which included a sample of 15,208 children and adolescents (aged 7-19 years). According to this information, the prevalence of children and adolescents with MS levels considered healthy in this period was 57.8%, 61.1% for males and 58.8% for females.

ABSTRACT The aim of this study was to update a systematic review on the use of active transportation to school in Brazilian children and adolescents. All studies were extracted from the LILACS; BIREME; SCIELO and MEDLINE. The search was carried out on manuscripts published in the period 2018-2019. The descriptors were used in Portuguese, English and Spanish. In overall, 8 manuscripts were included in this systematic review, with 1 presenting data from three periods (2009, 2012 and 2015). The study data were obtained between 2009 and 2015 and the age group found between 7 to 19 years old. Of the selected articles, 2 presented national data, 1 from the north, 2 from the northeast, 1 from the southeast and 2 from the south of Brazil. The use of active transportation was superior to passive transportation on 6 occasions and its use was common in boys than in girls (4 of 6 articles). The use of active transportation is still more common than passive transportation in most Brazilian regions, although some cities have the opposite. The results suggest that the prevalence of active transportation is higher in boys than girls. Public policies must be created to favor the use of active transportation among Brazilian youth.

abstract This study aimed to update the review of Brazil’s Report Card on the prevalence of global physical activity (PA) among Brazilian children and adolescents. This systematic review included an electronic search of eight databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) and a manual search of the references of retrieved studies. Studies published in 2018 and 2019 that assessed global PA among Brazilian youth were included. A narrative approach to the results was adopted. The initial search retrieved 1,892 potentially relevant titles (1,244 titles after duplicate analysis), of which 62 (47 different studies) met all the inclusion criteria. Most updated studies were carried out in Southern (40.4%) and Southeastern (25.5%) Brazil. Six studies provided data from national surveys (12.8%), and one study included preschool children (< 5 years old). Ten studies objectively measured PA (accelerometer or pedometer devices). In the updated studies, the overall proportion of young people who were physically active ranged from 9.8% to 79.6%. Three national surveys reported the prevalence of physically active students, ranging from 18.4% to 78.8%. There was an increase of surveys that objectively measured PA and with children under 12 years of age in the 2018 and 2019 studies. However, important research gaps (e.g., variations in the measurement of global PA), even in the same study, should be considered to improve the monitoring and evaluation of global PA in Brazil.
本研究旨在更新巴西关于全球体育活动(PA)在巴西儿童和青少年中的流行程度的报告卡。该系统综述包括对8个数据库(PubMed、Scopus、Web of Science、LILACS、SPORTDiscus、BIREME、Scielo和Google Scholar)的电子检索和对检索研究的参考文献的人工检索。2018年和2019年发表的研究评估了巴西青年的全球PA。对结果采取了叙述的方法。初始检索检索到1892篇潜在相关文献(重复分析后检索到1244篇)，其中62篇(47篇不同的研究)符合所有纳入标准。大多数最新研究在巴西南部(40.4%)和东南部(25.5%)进行。6项研究提供了来自全国调查的数据(12.8%)，1项研究包括学龄前儿童(< 5岁)。10项研究客观地测量了PA(加速计或计步器设备)。在最新的研究中，参加体育锻炼的年轻人的总体比例从9.8%到79.6%不等。三项全国性调查报告了体育活动学生的患病率，从18.4%到78.8%不等。在2018年和2019年的研究中，客观测量PA和12岁以下儿童的调查有所增加。然而，即使在同一项研究中，也应该考虑到重要的研究差距(例如，全球PA测量的变化)，以改进巴西对全球PA的监测和评价。

abstract – This study aimed to summarize existing research examining the prevalence of adequate sleep duration or meeting sleep recommendations among Brazilian children and adolescents. A systematic review was conducted on eight databases. The criteria for inclusion were original research, samples including Brazilian children and adolescents (age 0–18), studies that reported variables regarding sleep duration using both objective or subjective measures, school- or population-based surveys with random sampling, and cross-sectional or cohort studies. Of the 54 articles included, only 27 used data from different studies. Most of the studies were conducted in the southern region (n = 17) with only two studies having a nationally representative sample. Two studies included children below age five, and the age group most investigated was adolescents (>10 years old). A majority of the studies used a self-reported questionnaire and showed variability in the cutoff point applied for adequate sleep duration with the most reported being ≥8 hours. The proportion of adolescents who met recommendations or had adequate sleep duration ranged from 15% to 89%. Among children, the prevalence ranged from 17% to 95%. The least variability was observed among toddlers, ranging from 93% to 95%. No consistent gender differences were observed among the gender-stratified groups of children and adolescents across the studies. It can be observed that, because of the wide range of results and the lack of data with national representativeness, the prevalence of sufficient sleep among young people aged below 18 remains undefined in Brazil.

Abstract – The objective of this systematic review was to identify the association between overweight/obesity and level of physical activity in Brazilian children and adolescents in the school setting. For search strategy, the main reference databases (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC) were used. Baseline searches resulted in 3,265 potentially relevant titles (2,775 titles after removal of duplicate studies); 21 studies met all inclusion criteria and were included for analysis. Studies were carried out from 2007 to 2019; 47.6% of them were conducted in Southern Brazil, and only one study had nationwide approach. Prevalence from 5.4% to 21% was identified for overweight, 3.5% to 16.9% for obesity and 11.8% to 40.1% for overweight + obesity. According to results, 64.3% of overweight, 69.8% of obese and 37.7% of young overweight people were considered insufficiently active. The non-standardization of instruments to assess levels of physical activity and the lack of information regarding other Brazilian regions were classified as important limitations. The results reinforce the increase in the prevalence of overweight in Brazilian children and adolescents, and the high prevalence of physical inactivity among them. For every ten overweight children/adolescents, six are reported to be insufficiently active.
摘要:本系统综述的目的是确定巴西儿童和青少年在学校环境中超重/肥胖与身体活动水平之间的关系。检索策略采用PubMed、LILACS、SciELO、SPORTDiscus、Web of Science、ERIC等主要参考数据库。基线检索结果为3265个潜在相关标题(删除重复研究后为2775个标题);21项研究符合所有纳入标准并纳入分析。研究于2007年至2019年进行;其中47.6%是在巴西南部进行的，只有一项研究采用了全国性的方法。超重患病率为5.4%至21%，肥胖患病率为3.5%至16.9%，超重+肥胖患病率为11.8%至40.1%。结果显示，64.3%的超重者、69.8%的肥胖者和37.7%的青少年超重者被认为运动不足。评估体育活动水平的工具未标准化以及缺乏关于巴西其他地区的信息被列为重要限制。研究结果进一步证实了巴西儿童和青少年中超重患病率的上升，以及他们中缺乏身体活动的高患病率。据报道，每10名超重儿童/青少年中，就有6名活动不足。

abstract The aim of the study was to update Brazilian evidence on the prevalence of children and adolescents who met health criteria for aerobic fitness. This systematic review is part of the Report Card Brazil Project and the search was restricted to studies published during the period from January 2018 to December 2019 in nine electronic databases. Studies with different designs, which allowed extracting information about the prevalence of children and adolescents who met health criteria for aerobic fitness (age up to 19 years or average age up to 19 years) were included. Studies published from 2020 were not included due to the possible effect of the pandemic on this indicator and because there is no certainty as to when the pandemic will end. Of the 694 studies initially identified, 13 studies with information of 14,673 children and adolescents were included after reading titles, abstracts, full texts and references. The prevalence of children and adolescents who met health criteria for aerobic fitness was 26.9% (29.7% for girls; 44.6% for boys). In this search, eight different cutoff points were used to determine adequate aerobic fitness levels and five tests were used to determine aerobic fitness. Analyzing data from the present review with the previous systematic review of this project, one third of children and adolescents in Brazil meet health criteria for aerobic fitness.

abstract Children with obesity present greater foot loads during walking when compared to eutrophic ones. However, the acute effects of a moderate walking on the distribution of plantar pressure in children with obesity are still incipient in the literature. Our aim was to verify the acute effects of six-minute walk test on plantar pressure in obese and eutrophic children. A pressure platform was used to record plantar pressure during walking for 62 children (37 girls), aged 7-10 years old, before and after the six-minute walk test. Children were divided into an obese group - OB (n = 20), and an eutrophic group - EU (n = 42). Peak plantar pressure (PPP), maximum force (MF), and contact area (CA) were assessed in three trials during walking at a comfortable speed. The analyses were performed in five plantar regions: rearfoot, midfoot, forefoot, hallux, and toes. For the PPP was higher under the midfoot region of the OB group after walking. In the comparison between groups, PPP, MF, and CA were higher for the OB group for most regions. We concluded that, after a moderate walking activity, children with obesity experience an increase in plantar loads, especially under the midfoot, which can bring greater discomfort and risk of injuries.

resumo A pandemia da COVID-19 afetou diversas atividades humanas, tais como práticas de medições antropométricas, desde o campo clínico e de pesquisa até o campo do ensino. Dada a falta de vacinas e/ou medicamentos eficazes contra a COVID-19, a Organização Mundial da Saúde (OMS) recomendou medidas de prevenção e enfrentamento da doença. Essas recomendações foram posteriormente endossadas pela Sociedade Internacional para o Avanço da Cineantropometria/ International Society for the Advancement of Kinanthropometry (ISAK), com adaptações às rotinas antropométricas, que complementamos para aplicação abrangente nos diversos segmentos de atuação da antropometria. Este ponto de vista visa enfatizar e contribuir às considerações de segurança das rotinas antropométricas em um mundo pós-COVID-19. Entende-se aqui que o protocolo de biossegurança apresentado neste ponto de vista para retorno e continuidade das atividades antropométricas, no mundo inteiro, independentemente da formação/ capacitação/ atuação profissional, no que diz respeito à vida e às comunidades, também pode ter aplicação recorrente no combate a outros patógenos respiratórios semelhantes para se transformarem em pandemias no futuro. Sugere-se o desenvolvimento de vídeos demonstrativos das recomendações deste ponto de vista para reforçar as boas práticas higiênico-sanitárias a serem adotadas pelos profissionais da antropometria na realização das medições do corpo humano.

abstract The study aimed to verify the correlation between resting heart rate variability (HRVrest) and endurance performance in female futsal players, as well as to evaluate the reliability of this parasympathetic autonomic marker. A total of 16 female futsal players (age: 22 ± 3 years; VO2max: 42.3 ± 2.0 ml.kg-1.min-1) were evaluated during the first week of preseason training. Vagal modulation was evaluated from the HRVrest (i.e., log-transformed root mean square of successive R-R interval differences - Ln-RMSSD) for two consecutive days, while endurance performance was evaluated by the Yo-Yo Intermittent Recovery Test, Level 1 (Yo-Yo IR1). Pearson correlation was used to analyze the relationship between the variables. Strong correlation between the HRVrest index and endurance performance (r = 0.643; p = 0.007). Reliability was tested through the intraclass correlation coefficient, coefficient of variation (CV), and Bland-Altman analysis of the agreement. Furthermore, acceptable repeatability of HRVrest, but with great inter-subject variability (ICC = 0.670, 95%CI = 0.056-0.885, CV = 15.8%). The current study demonstrated a strong correlation between Ln-RMSSD and endurance performance, and despite the acceptable values of intrasubject reliability, HRVrest presented high inter-individual variability in female futsal players.

abstract Sports science has showed benefits in the use of small-sided games in the teaching-learning and training processes of football. We propose that such benefits occur because the small-sided games are holons of a hierarchically organized that maintain the same characteristics of game, regardless the reduced complexity. The hierarchical model of football considers the numerical relations of cooperation and opposition in specific spaces of play. It characterizes a nested hierarchy model because it deals with both the parts and the different processes of game. Such a hierarchical model contains five levels, in which the upper level is the football game and the elementary level a game situation, that is, a small-sided game. As any open system of hierarchical organization, the small-sided games present simultaneously invariant characteristics of whole and the specificities of the parts according the context and level of analysis. The adoption of such a hierarchical perspective allows setting goals as well as selecting the teaching-learning and training’s contents at different analysis levels by considering the autonomy-dependency in each one.
