Objective: To investigate the difference in the proportion of students with metabolic syndrome, diagnosed according to different criteria.Methods: The sample consisted of 241 students (136 boys and 105 girls) aged 10 to 14 years, from public and private schools in Paranavaí, Paraná. We used three distinct diagnostic criteria for metabolic syndrome, considering the presence of at least three of the following risk factors: increased waist circumference, hypertension, fasting hyperglycemia, low HDL-C, and elevated triglycerides.Results: The prevalence of metabolic syndrome found was 1.7% (confidence interval of 95% - 95%CI 0-3.3) for the IDF criterion; 3.3% (95%CI 1.0-5.6) for Cook; and 17.4% (95%CI 12.6-22.3) for Ferranti. Analyzing the criteria in pairs, the agreement between IDF and Cook was 97.5% (k=0.95); between IDF and Ferranti, 83.4% (k=0.67); and between Cook and Ferranti, 85.9% (k=0.72). Onlyone student (0.4%) was diagnosed with metabolic syndrome solely by the IDF criterion, while 34 (14.1%) were diagnosed exclusively by Ferranti. The comparison of the three criteria showed that Ferranti presented the highest proportion of metabolic syndrome (p<0.001), and Cook had a greater proportion than IDF (p<0.001).Conclusions: We found a significant difference in the proportion of metabolic syndrome in the three criteria. The choice of which criterion to use can compromise not only the percentage of metabolic syndrome prevalence but also interfere in strategies of intervention and prevention in children and adolescents with and without metabolic syndrome, respectively.

Anterior cruciate ligament (ACL) rupture is an injury in young adults, triggering undesirable neuromuscular effects. A rehabilitation program is structured with exercises that aid in intensive care training, and proprioceptive training has been proposed as one of the training / rehabilitation methods in patients undergoing ACL reconstruction. Thus, this study aimed to analyze, through a systematic literature review, the effects of including proprioceptive training on different outcomes (stability / balance, proprioception, strength, functional capacity, coordination) after ACL reconstruction surgery in young adults. The search of the articles included studies in the last ten years, being a search conducted in November 2018. Searches were conducted in the electronic databases of PubMed and Science Direct with a following search methodology: (("Proprioception" [Mesh] ) OR "Proprioception" [Word Text]) AND ("Anterior Cruciate Ligament" [Mesh] OR "Anterior Cruciate Ligament Reconstruction" [Mesh] OR "Anterior Cruciate Ligament Injury" [Mesh]). Six studies were selected for the analysis and the results obtained there is insufficient scientific evidence showing the positive effects of training in proprioceptive training after ACL reconstruction in adults, in view of a shortage of studies, such as discrepancies in findings, without time of intervention and in the tests contracted in the analysis of the variables.

OBJETIVO: Verificar se o tempo de prática no Pilates e a prática adicional de outro exercício físico influenciam na aptidão física de idosos praticantes de Pilates. MATERIAIS E MÉTODOS: O estudo transversal foi composto por 60 idosos praticantes de Pilates de estúdios e academias da cidade de Maringá- Paraná, Brasil em 2019. Todas as análises foram realizadas nas próprias academias, sendo as variáveis sóciodemográficas analisadas por meio de um questionário semiestruturado e as capacidades físicas aferidas pela bateria Senior Fitness Test. As análises de dados foram conduzidas por meio da Anova One-Way e do teste t de student independente (p 0,05). RESULTADOS: Idosos que praticam o Pilates há mais de três anos apresentaram melhor desempenho no teste de alcançar atrás das costas (x = -4,96) em comparação aos idosos que praticam a modalidade entre três e 12 meses (x= -14,43 cm). Ainda, os idosos que praticam apenas o Pilates apresentaram aptidão física semelhante aos idosos que também praticam outro exercício. CONCLUSÃO: Não houve diferenças significantes entre quem pratica outro tipo de exercício físico associado ao Pilates nos diferentes componentes da aptidão física. Porém, o maior volume total de tempo de prática do Pilates, aparentemente, proporciona melhores resultados sobre a flexibilidade de membros superiores de idosos.

The time spent in front of the screens, results in accumulations of sedentary behavior, which is related to health damages to adolescents, such as a low cardiorespiratory fitness. In this sense, this study aimed to predict cardiorespiratory fitness through screen time in schoolchildren. Cross-sectional study, as a sample composed of 2.764, of which 1.370 boys and 1.394 girls between 10 and 18 years old were the public school system of Paranavaí, Paraná, Brazil The self-report questionnaire was used to estimate screen time (ST) and cardiorespiratory fitness (CF) was estimated using the 20-meter multi-stage test, and to verify the predictive power of the screen time in relation to CF, the Roc curve was used. The results showed that screen time was considered a good predictor of cardiorespiratory fitness in boys (weekdays, weekends and all week), and in general (boys and girls) only for weekdays (Monday to Friday). In the survey, the screen time cut-off for boys on weekdays was 137 minutes  (CI: 65-43), at weekends of 165 minutes (58-51) and general of 156 minutes (64-45). For the general sample (girls and boys), the cut bridge on weekdays was 142 minytes (64-44). For the girls the screen time had no predictive power (CI> 0.50) and consequently the cut-off point was not verified. Thus, it can be concluded that the screen time in boys and in general (only weekdays) was able to predict cardiorespiratory fitness and that this variable of easy application can be an important tool to predict CF in the school environment.
