El objetivo fue investigar la validad del teste de RAST (Running-based Anaerobic Sprint Test) en evaluar el desempeño de la potencia anaeróbica través del uso del teste de Wingate en ciclistas trenados. Participaron del estudio 10 ciclistas masculinos (28,0±7,3 años) de la modalidad de Mountain bike. Después de la mensuración de las variables antropométricas, la potencia pico (PP), media (PM) y el índice de fatiga (IF) fueron determinados al acaso a partir de dos testes de Wingate y de dos testes de RAST. Fueron utilizados el test t independiente de Student, el análisis de correlación linear de Pearson (r) y el test de Bland-Altman. Los resultados demostraron, contrariamente al IF (33.8±4.6% vs. 37.8±7.9%; r=0.172), diferencias significativas entre el teste de Wingate y el RAST para PP y PM (W.kg-1 e W). Mismo que los valores de correlación de PP e PM (W) tengan sido fortes (0,831 e 0,714, respectivamente), la concordancia

Objective: To investigate the agreement between two international criteria for classification of children and adolescents nutritional status. Methods:The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index. Nutritional status was classified according to the cut-off points defined by the World Health Organization and the International Obesity Task Force. The agreement was evaluated using Kappa statistic and weighted Kappa. Results:In order to classify the nutritional status, the agreement between the criteria was higher for the boys (Kappa 0.77) compared to girls (Kappa 0.61). The weighted Kappa was also higher for boys (0.85) in comparison to girls (0.77). Kappa index varied according to age. When the nutritional status was classified in only two categories - appropriate (thinness + accentuated thinness + eutrophy) and overweight (overweight + obesity + severe obesity) -, the Kappa index presented higher values than those related to the classification in six categories. Conclusions:A substantial agreement was observed between the criteria, being higher in males and varying according to the age.

Introduction: Evidence suggests that a higher distribution of elite athletes have birth dates in the first few months of the year. However, the advantages of birth month on performance related to starter status, structure and body composition in female futsal (5-a-side football played on a hard court, mainly indoors), are unknown. Objective: To determine the effect of relative age (ERA) on competitive female futsal athletes, and its influence on anthropometric profile and starter status. Methods: One hundred and fifteen athletes, participants in the 20th Brazilian Cup of Adult Futsal Clubs, special division, were submitted to measurements of body mass, height, skinfold thickness, body perimeters and bone diameters, in order to characterize the anthropometric profile and determine the body somatotype. The athletes were distributed in semesters and quartiles of the months of the year, according to their birth dates. Differences in the distribution of expected and observed birth dates were tested using Chi-square tests (χ2). Comparisons between semesters and birth quartiles were performed using parametric and non-parametric tests. Results: There was no ERA in distribution (p=0.248), anthropometric profile (p=0.872 to 0.912), or starter status between athletes born from January to June (p=0.352) and those born between July and December (p=0.744). On the other hand, those born in the first months of the year showed longer practice times than those born in the latter months of the year. Conclusion: Although the ERA in this study reveals longer practice times favoring female futsal athletes born in the first quartile of the year, it did not influence the starter status, the distribution in the teams, or any advantage in anthropometric profile. Level of evidence III, Case-Control Study.

ABSTRACT. Current analysis compares anthropometric indexes of obesity, blood pressure and static muscle strength among workers who exercised or did not exercise themselves on the workplace. Three hundred and fifty-four workers, of whom 178 did not perform any physical exercises and 176 who did, were evaluated by means of a query on their participation in workplace exercises during the last 30 days. Their systolic (SBP) and diastolic blood pressure (DBP) was measured; height, body mass and waist circumference (WC) were taken; four static muscle strength tests (right and left handgrip strength, scapular strength and lumbar strength) were performed. The Shapiro Wilk test revealed asymmetry in the data presented as median and interquartile variance. Mann-Whitney test was used to compare data between the two groups. Results did not reveal any difference for body mass index (BMI), WC, SBP, DBP and mean blood pressure (MBP) between the groups. However, greater performance was an asset for all participants in workplace exercises for all static strength tests. There is evidence that workers who performed workplace exercises may increase muscle strength without any changes in BMI, WC and blood pressure.Keywords: occupational health, gymnastics, blood pressure, worksite physical activity, muscle strength.Ginástica laboral, indicadores antropométricos de obesidade, pressão arterial e força muscular estática RESUMO. O objetivo desta pesquisa foi comparar indicadores antropométricos de obesidade, pressão arterial sistêmica e força muscular estática entre trabalhadores que realizam e não realizam ginástica laboral. Trezentos e cinquenta e quatro trabalhadores, dos quais 178 praticavam e 176 não praticavam ginástica laboral, foram submetidos a uma avaliação que constituiu de uma pergunta sobre a participação no programa de ginástica laboral nos últimos 30 dias, verificação das pressões sistólica (PAS) e diastólica (PAD), medidas de estatura, massa corporal, circunferência da cintura (CC) e da realização de quatro testes de força muscular estática (preensão manual direita e esquerda, força escapular e força lombar). O teste de Shapiro Wilk revelou assimetria nos dados que foram apresentados como mediana e variância interquartil e, comparados entre os grupos por meio do teste de Mann-Whitney. Os resultados não revelaram diferenças para o índice de massa corporal (IMC), CC, PAS, PAD e pressão arterial média (PAM) entre os grupos. Por sua vez, foi verificado maior desempenho, favorecendo os participantes de ginástica laboral, em todos os testes de força estática. Há evidências que os trabalhadores que realizam ginástica laboral podem aumentar a força muscular, porém sem alterar o IMC, a CC e a pressão arterial.Palavras-chave: saúde do trabalhador, ginástica, pressão arterial, atividade física no local de trabalho, força muscular.

This study calculated the exposure-response rates of social-ecological correlates of practicing regular (>150 min/week) leisure-time physical activity (PA) in 393,648 adults from the 27 Brazilian state capitals who participated in a national survey between 2006 and 2016. Regular PA encouraging factors were inputted into an exposure-response model. Growth rates for the odds ratio and prevalence of regular PA were calculated for each increase of one encouraging factor. Regular PA was reported by 22% of the participants (25% of men and 20% of women). More than 40% of men and 30% of women with higher intra-personal encouraging conditions reported practicing regular PA. There was a 3% (ages 18–32 years) to 5% (ages 46–60 years) increase in regular PA practice in men for each increase in an encouraging climate factor (temperature from 21 °C to 31 °C, humidity from 65% to 85%, 2430 to 3250 h of sun/year, and from 1560 to 1910 mm of rain/year). Encouraging intra-personal factors and favorable climate conditions had larger effects on regular PA practice than the built environment and socio-political conditions; the latter two had independent effects, but did not have a cumulative effect on PA.

Marital status mediates an association between physical activity (PA) and TV time with health outcomes. However, population-based studies have revealed that the health effect of marriage or divorce is age-dependent and differs between women and men. The study aimed to identify the age and sex-related associations between marital status with PA and TV time. We used data from Vigitel, an annual telephone survey started in 2006 in Brazil. We applied a complex sample logistic regression model to estimate the odds for PA and TV time comparing marital statuses according to age and sex subgroups, independent of obesity, hypertension, diabetes, self-assessed poor health, and smoking. Our sample included 561,837 individuals from 18 to 99 years, with a TV time > 3 h/day (prevalence = 25.2%) and PA > 150 min/week (prevalence = 35%). Later, we divided our sample in seven age groups by marital status and sex. Compared to single individuals, married men and women were less likely to watch TV more than 3 h/day in participants >30 years old. When compared to single, married participants were less likely to do more than 150 min of PA/week at younger age groups. Married women older than 40 years were more likely to do more than 150 min of PA/week than the single ones, while there were no differences among married men by age group. In conclusion, our study suggests that the investments in public policies to encourage the practice of PA and reduction of TV time could be based on the marital status, sex, and age, prioritizing less active groups.

Obesogenic behaviors have been individually associated with bullying during adolescence. However, physical activity, sedentary behavior, and diet manifest themselves in synergy and even behavioral profiles in which positive and negative behaviors coexist can be more positively associated with psychosocial outcomes. The present study aimed to analyze the association between clusters of obesogenic behaviors and different bullying roles in Brazilian adolescents. This cross-sectional study used data from the Brazilian School-based Health Survey—PENSE, 2015. A total of 100,794 male and female adolescents of the ninth-grade elementary school participated in the study. Students responded to an electronic questionnaire. Clusters of obesogenic behavior consisted of physical activity, exposure to sedentary behavior, and diet, and the different roles in bullying were: participant, victim, bully, and bully–victim. Binary logistic regression with 95% confidence intervals (CI) was used for data analysis ( p < .05). Multiple adjustments and complex sampling procedures were employed. Adolescents in the cluster “Health-promoting sedentary behavior and Diet” had reduced chances of participating in bullying (odds ration [OR] = 0.70; 95% CI [0.64, 0.76]), of being a victim (OR = 0.87; 95% CI = 0.76–0.99), and being the bully (OR = 0.65; 95% CI [0.59, 0.71]); and those from the cluster “Health-promoting physical activity and Diet” had reduced chances of participating (OR = 0.81; 95% CI [0.76, 0.87]), being a victim of bullying (OR = 0.86; 95% CI [0.76, 0.98]), being the bully (OR = 0.79; 95% CI [0.72, 0.85]), and being a bully–victim (OR = 0.74; 95% CI [0.61, 0.90]), when compared to those from the “health-risk” cluster in the adjusted analysis. Clusters of obesogenic behavior may reduce adolescent bullying: victim, bully, and bully–victim benefit when exposed to healthier behavioral profiles. The school setting must recognize bullying as a problem and therefore simultaneously promote multi-component interventions to tackle physical activity, sedentary behavior, and eating behavior. Outcomes other than obesity should be acknowledged when promoting obesogenic behaviors.
