A sedentary life style is a factor of risk for the development of overweight and childhood obesity, conditions associated with dyslipidemia, arterial hypertension and insulin resistance, among other disorders. The objective of this study was to evaluate the nutritional status and the association with the profile of physical activity in Municipal Schools in Corumbá -MS. A cross-sectional study was carried out in a sample of 403 pupils, aged 7-10 years, in which children with Body Mass Index (BMI) values > 85 th and < 95 th and > 95 th percentile were classified in risk of overweight and overweight, respectively. The index of physical activity was determined by a specific questionnaire for the study, to obtain data about duration (minutes), intensity (metabolic equivalent) and energy expenditure (kcalories) of both active and sedentary physical activities. A prevalence of 6.2% e 6.5% to risk of overweight and overweight, respectively, was verified, with higher prevalence in girls than in boys. Most physical activities performed by children were light (< 3 METs) and moderated (3 a 6 METs); no vigorous (> 6 METs) physical activity was recorded. The older the children, the lesser the time spent in active physical activities. Normal-weight children are more active, practice more intense physical activities and spend less time watching television and playing video-games than overweight children. The data emphasize the importance of promoting changes in the life-style through the introduction of healthy habits, since infancy, and their maintenance for the whole life. Active children favor an active healthy adult population too, which can contribute, consequently, for a reduction in the incidence of morbidity and mortality at adulthood.

Background Physical training, regardless of the presence of concurrent weight loss, provides numerous health benefits for individuals who are overweight and obese and have or are at risk for cardiovascular disease. Purpose The purpose of this review was to identify different types of physical training programs (aerobic, resistance, or combined), with or without counseling/diet modifications, and their impact on physical fitness in individuals who have class II and III obesity. Data Sources Medline and Medline In-Process, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, Web of Science, LILACS, CINAHL, SPORTDiscus, PEDro, and PubMed were searched up to June 2017. Study Selection This review had the following inclusion criteria: body mass index of ≥35 kg/m2 and age 18 years or older; supervised physical training program; randomized controlled trial; physical fitness outcome (muscular strength, muscular endurance, cardiovascular endurance, and/or flexibility); in English or Portuguese; and available full-text article. Data Extraction Three reviewers independently extracted data, assessed study risk of bias using the Cochrane tool, and discussed disagreements until consensus was reached. Data Synthesis Of the 9460 identified articles, 26 were included and 8 were used in a meta-analysis. The meta-analysis showed improvements in walking speed and maximal oxygen uptake but not knee extension strength in the intervention groups. The Cochrane risk-of-bias score indicated that the majority of the data were from randomized controlled trials with a low or unclear risk of bias. Limitations The large variability of outcomes and interventions made comparisons difficult. Conclusions A combination of aerobic exercise and resistance exercise, in addition to diet modifications, may improve cardiovascular and muscular endurance in individuals with class II and III obesity. However, conclusions must be interpreted with caution because of the heterogeneity in interventions and outcome measures among the studies and an unclear risk of bias in several studies.

Introduction: Obesity is a global public health problem with negative impact on health. Therefore, effective treatments options are needed. Objective: to evaluate the responses of a supervised functional training program on physical fitness and functional capacity of women with obesity. Methods: a prospective and controlled study was conducted with twenty-four women, BMI >30 and <55 kg/m² and age between 20 and 59 years. The evaluation consisted of anthropometric measurements and physical fitness tests that assessed the cardiorespiratory fitness and functional capacity [6-minute step test (ST6min)], the indirect strength of the lower limbs [sit-to-stand test (STS)] and the flexibility [sit and reach test (SR)]. After the baseline evaluations, the volunteers were allocated in two groups: individualized training group (ITG) (n=13), which consisted of aerobic and strength training, for three months, three times a week, 60 minutes per session; and the control group (CG) (n=11) which did not participate in any regular physical exercise program during the same period. At the third month the two groups were reassessed. Results: it was observed significative reductions in waist circumference, hip and neck measurements; all with p<0.01; and increase in VO2max, in the number of movements of STS and in distance reached in the SR test, all with p<0.01 for the ITG. The ITG showed superiority over CG for all exercise test variables studied. Conclusion: The training program improved the distribution of body fat, cardiorespiratory fitness, muscular strength, flexibility and functional capacity. These are indicatives that the strategy is feasible for women with obesity.

Introduction: Physical inactivity is the fourth biggest risk factor for global mortality. In Brazilian metallurgical industries, workers present a high incidence of musculoskeletal symptoms as one of the main causes of absenteeism. Objectives: To investigate the impact of physical activity levels and leisure-time physical exercise on musculoskeletal symptoms and absenteeism among administrative and production workers of a metallurgical industry. Methods: This is a transversal study that included 206 workers. We applied the Modified Baecke Questionnaire, leisure-time physical activity and leisure-time physical exercise domains), as well as the Nordic Musculoskeletal Questionnaire regarding symptom occurrence and severity scores (1-4), and compared levels of absenteeism. Our sample was divided into 2 groups: production and office workers. Results: We observed a significant difference between the groups regarding symptom severity score 3 (p = 0.03) and absenteeism (p = 0.02); the production group presented higher results. There was a correlation between leisure-time physical exercise and absenteeism (r = -0.57, p = 0.01) and between leisure-time physical activity and absenteeism (r = -0.55, p = 0.01) in the production worker group, whereas in the office worker group, leisure-time physical activity and symptom severity score 4 were correlated (r = 0.63, p = 0.02). Conclusions: Production workers presented higher occurrences of symptom severity score 3 and absenteeism; increased levels of leisure-time physical activity and physical exercise reduced absenteeism. Leisure-time physical activity was correlated with severity score 4 in the office worker group.
