Background Working memory performance is associated with better academic achievements in children and adolescents, and it is positively related to CRF. However, what level of cardiorespiratory fitness (CRF) discriminates higher working memory performance is not known. The purpose of this study was to identify CRF thresholds linked to working memory in adolescents. Methods Data of 141 adolescents (53.2 % girls) were collected (14.9 years) from a cross-sectional study during the year 2019. CRF was assessed by the 20-m shuttle run test, and maximal oxygen uptake was calculated using the Mahar´s equation. Working memory was evaluated by the Corsi blocks test and performance was classified by percentiles. Receiver operating characteristic (ROC) curve analysis was used to identify CRF thresholds. Results The ROC analysis indicated that CRF could be used to discriminate working memory in adolescents. CRF thresholds of ≥45.03 ml.kg− 1.min− 1for boys and ≥36.63 ml.kg− 1.min− 1for girls were found to be indicative of “normal” working memory performance. Conclusions CRF could discriminate low and normal working memory performance in 14-16- year-old adolescents. These thresholds could allow for earlier identification and intervention of low working memory performance using CRF.

<p>Estudos prospectivos visam identificar conhecimentos e tecnologias aplicadas no setor da saúde, visando o tratamento de doenças com o uso de plantas medicinais, destacando-se nesta pesquisa as plantas do gênero <em>Baccharis</em>. Este gênero de planta contém diversos compostos bioativos com ações terapêuticas importantes para a promoção da saúde humana. Sendo assim, o artigo apresentou um mapeamento de patentes depositadas que utilizam o gênero <em>Baccharis</em> como agente benéfico à saúde. As patentes foram pesquisadas nas bases de dados: INPI, LATIPAT e EPO, utilizando os descritores: <em>Baccharis</em>, <em>Baccharis</em> atividade, <em>Baccharis</em> processos, <em>Baccharis</em> produtos. Foram selecionadas 45 patentes e destas, 12 foram selecionadas para o estudo. Verificou-se que o número de patentes encontradas é relativamente baixo e o maior número de patentes é classificada como A61K, referindo-se ao maior potencial da planta, cujo é utilizado para a elaboração de produtos relacionados à ciência médica e higiene. </p>

O objetivo deste trabalho foi descrever experiências e resultados vinculados ao projeto de extensão “Clínica e Academia Escola de Educação Física: prescrição de exercícios físicos baseados em evidências científicas”. O público atendido é constituído de pacientes portadores de doenças crônicas. A prescrição dos exercícios é planejada e ministrada por acadêmicos, pós-graduandos e docentes mediante informações individualizada do participante. O programa é elaborado considerando evidências científicas obtidas a partir de diretrizes e ensaios clínicos randomizados que respaldam a determinação da dose adequada de exercícios físicos individualizados. Resultados de 64 pacientes revelaram melhoras significativas na adiposidade abdominal, na força de preensão manual, na frequência cardíaca de repouso e na pressão arterial diastólica. Em relação à qualificação, observou-se envolvimento e interesse dos acadêmicos com programas de mestrado, de residência e com a prática profissional neste contexto, durante e após a graduação. A proposta extensionista tem potencial de desenvolvimento contínuo, aplicação prática e formação profissional, consolidando em importante papel das instituições de ensino superior no que diz respeito à consolidação da tríade acadêmica: ensino, pesquisa e extensão.

We aimed to characterize the age of onset of training, age at menarche, menstrual periodicity, and performance perception during the menstrual cycle and examined the impact of these reproductive variables on body composition, morphology, and body weight satisfaction in Brazilian elite futsal players. The study consisted of 115 female Brazilian elite futsal players from the top national teams. Data were collected during the twentieth Women’s Brazil Futsal Cup. Players were interviewed and self-reported their age of onset of training, age at menarche, menstrual periodicity, and the menstrual period, where they performed best. We also asked for what they considered to be their ideal body weight as well as information related to their training (i.e., volume and frequency). Subsequently, anthropometric measurements (i.e., body mass, height, circumferences, diameters, and skinfold thickness) were performed to estimate the body composition and determine morphological characteristics (e.g., somatotype). Fifty-nine (53.2%) players were postmenarche-trained and 52 (46.8%) were premenarche-trained. Eighteen (16.2%), 65 (58.6%), and 28 (25.2%) were classified as early, normal, and late menarche, respectively. Only 11 (9.6%) and 1 (0.9%) had irregular menstrual cycles and were amenorrheic, respectively. Seventy-three (69.5%), 23 (21.9%), and 9 (8.6%) reported that their game performance was the best at the follicular phase, menses, and luteal phase of the menstrual cycle, respectively. No associations between the four reproductive-related variables were found. Postmenarche-trained players had significant lower age at menarche and higher percentage body fat. The somatotype profile registered lower ectomorphy rate for the postmenarche-trained participants after controlling for covariates. Early menarche group presented higher sum of six skinfold thickness and endomorphy rate compared to normal and late menarche groups. No differences were found when menstrual periodicity groups and best performance groups were compared, except for higher femur width in the regular menstrual cycle group compared to the irregular one. The association between body weight satisfaction and the four reproductive-related variables were not observed. Premenarche-trained Brazilian elite futsal players had the menarche later than the postmenarche-trained athletes. Most of the participants had menarche age classified as “normal,” presented “regular” menstrual cycles and perceived to perform better during the follicular phase of the menstrual cycle.

Background: Increase of musculoskeletal disorders is related to an economic burden; also elevate time spend in sedentary behavior can lead to a decrease in physical fitness and consequently an incidence in musculoskeletal disorders. The aim of the study was to evaluate if low lumbar traction strength and flexibility could predict musculoskeletal pain in university staff in two years. Methods: This is a longitudinal study with 2-year follow-up. Fifty-three university staff members participated in this longitudinal study: age = 38±8 years, height = 171±10 cm, body mass = 75±14 kg, and body mass index = 26±4 m/kg2. The participants performed the lumbar traction and the sit and reach tests, and completed the Corlett and Bishop body map and musculoskeletal pain questionnaire at baseline and two years later. Results: There was a 4% increase in pain prevalence on year 2, but 62% of the participants remained in the same pain classification. Men presented 11% decrease in lumbar traction strength, whereas women presented 21% decrease in strength. Flexibility level at baseline was not associated with developing pain. However, individuals in the lower 75th lumbar traction strength percentile at baseline had 3.2 higher odds of reporting musculoskeletal pain two years later than those in the higher 25th strength percentile. Conclusion: University staff presented decreases in lumbar traction strength and flexibility over a two year period. Weaker individuals at baseline were more likely to report musculoskeletal pain two years later than those who were stronger. Flexibility levels were not associated with developing pain.
