BackgroundThe importance of assessing body fat variables and physical fitness tests plays an important role in monitoring the level of activity and physical fitness of the general population. The objective of this study was to develop reference norms to evaluate the physical fitness aptitudes of children and adolescents based on age and sex from the lake region of Itaipú, Brazil.MethodsA descriptive cross-sectional study was carried out with 5,962 students (2,938 males and 3,024 females) with an age range of 6.0 and 17.9 years. Weight (kg), height (cm), and triceps (mm), and sub-scapular skinfolds (mm) were measured. Body Mass Index (BMI kg/m2) was calculated. To evaluate the four physical fitness aptitude dimensions (morphological, muscular strength, flexibility, and cardio-respiratory), the following physical education tests were given to the students: sit-and-reach (cm), push-ups (rep), standing long jump (cm), and 20-m shuttle run (m).Results and DiscussionFemales showed greater flexibility in the sit-and-reach test and greater body fat than the males. No differences were found in BMI. Percentiles were created for the four components for the physical fitness aptitudes, BMI, and skinfolds by using the LMS method based on age and sex. The proposed reference values may be used for detecting talents and promoting health in children and adolescents.

Saúde UNIPAR, Umuarama, v. 18, n. 3, p, 189-197, set/dez. 2014. RESUMO:O objetivo deste estudo foi revisar as pesquisas de prevalência de sobrepeso e obesidade em crianças e adolescentes brasileiros. Foi realizado a busca eletrônica de artigos nas bases de dados Scielo, PubMed, MedLine e LILACS e na Biblioteca Eletrônica Bireme. Para efeito deste estudo, foram selecionadas as publicações de 2003 a 2013. Foram analisados 59 estudos que atenderam aos critérios de inclusão estabelecidos pelos autores. A maioria dos estudos foram desenvolvidos nas regiões Sul e Sudeste (71,2%), com uma amostragem bem diversificada que variou de 328 a 79,6795 sujeitos. O Índice de Massa Corporal -IMC foi o protocolo mais utilizado (93,2%) e o critério de classificação de sobrepeso/obesidade sugerido pela International Obesity Task Force -IOTF foi amplamente utilizado nos estudos (52,5%). A prevalência de sobrepeso/obesidade oscilou de 7,4% a 36,5%, com mais de 70% dos estudos com prevalência de sobrepeso/ obesidade superior a 20%, sendo mais elevada nos rapazes. Apesar das diferenças metodológicas, a maioria dos estudos com crianças e adolescentes brasileiros apresentou valores bastante elevados de prevalência de sobrepeso/obesidade sugerindo um constante crescimento deste problema em nosso país. PALAVRAS-CHAVES: Sobrepeso; Obesidade; Crianças; Adolescentes; Revisão Sistemática. PREVALENCE OF OVERWEIGHT AND OBESITY IN CHILDREN AND ADOLESCENTS IN BRAZIL: A SYSTEMATIC REVIEWABSTRACT: The aim of this study was to review the research into the prevalence of overweight/obesity among Brazilian children and adolescents. An electronic search was conducted for articles in the Scielo, PubMed, MedLine and LILACS and Bireme Electronic Library databases. For this study, publications from 2003 to 2013 were selected. A total of 59 studies that met the inclusion criteria set by the authors were analyzed. Most of the studies were performed in the South and Southeast (71.2%) regions, with a well diversified sampling ranging from 328 to 79,795 subjects. The Body Mass Index -BMI was the most frequently used protocol (93.2%) and the criterion for overweight/obesity classification suggested by the International Obesity Task Force -IOTF was widely used in the studies (52.5%). The overweight/obesity prevalence ranged from 7.4% to 36.5%, with more than 70% of studies with overweight/obesity prevalence greater than 20%, being higher in boys. Despite the methodological differences, most studies on Brazilian children and adolescents presented very high values of overweight/ obesity prevalence, suggesting constant growth of this issue in our country.

Comparisons of mood states associated with outcomes achieved by female and male athletes in high-level judo and Brazilian jiujitsu championships: psychological factors associated with the probability of success. J Strength Cond Res 35(9): 2518-2524, 2019-Moods can be used to predict the performance of athletes in various sports; accordingly, we selected the Brunel Mood Scale (BRUMS) to evaluate mood states of high-level judo and Brazilian jiu-jitsu (BJJ) athletes. The aims of this study were (a) to compare the mood states of high-level female and male athletes in BJJ and judo championships in relation to their performance outcomes and (b) to verify associations between psychological factors and performance in estimating their probability of success. The subjects were 173 grappling athletes (judo, n 5 85 and BJJ, n 5 88), separated into male (n 5 129, 40 winners and 89 nonwinners) and female (n 5 44, 23 winners and 21 nonwinners) groups. Each subject's mood state was assessed 60 minutes before the first match using the BRUMS (tension, depression, anger, vigor, fatigue, and mental confusion dimensions). Descriptive and inferential statistics (including logistic regression and variance analysis) were used to evaluate relations between mood states and performance (i.e., winning/losing), with p # 0.05. Analysis showed significant differences between male and female athletes in vigor and fatigue, and differences between male judo and male BJJ athletes in tension, vigor, confusion, and fatigue. Female judo and female BJJ athletes showed significant differences in depression and vigor. Logistic regression revealed that higher levels of anger and tension increased athletes' chances of performing well in a match by 23 and 13%, respectively. In addition, lower levels of depression increased athletes' chances of better performance by up to 32%. Overall, we observed a significant relationship between mood state and sports performance. Thus, coaching staff and athletes should monitor athletes' mood states before competitions to ensure that they are in optimal condition to perform and use psychological interventions to support judo and BJJ preparation.

Overweight and obesity in childhood and adolescence have reached alarming rates in Brazil. The aim of this study was to analyze the prevalence rates of overweight and obesity according to socioeconomic status, gender and age in schoolchildren from 11 towns around the Itaipu Lake, western Paraná. The sample consisted of 5,962 subjects (3,024 girls) aged 6 to 17 years. Overweight and obesity were identified based on body mass index, adopting the cutoff values for age and gender suggested by the International Obesity Task Force. The prevalence rates according to different strata (gender, age and socioeconomic status) were compared by means of logistic regression using odds ratios. The prevalence of overweight and obesity was 14.8% and 5.8% among boys, respectively, and 15.2% and 4.5% among girls. The prevalence rates decreased with increasing age. Considering socioeconomic status, the prevalence of overweight and obesity was significantly higher in schoolchildren from high-income families. The prevalence rates indicate a trend similar to that observed for the highest prevalence reported in surveys conducted in other cities and regions of Brazil. The present results suggest the need for interventions of the public health system and of society, seeking alternatives to alleviate this problem and its consequences.
