O sedentarismo é um problema que afeta milhões de pessoas em todo o mundo, e para vários autores a redução ou até mesmo a extinção deste comportamento inativo deve ser encarada como prioridade para elevar a qualidade de vida da população. Para isso, se faz necessário, definir o problema, identificando a prevalência deste estilo de vida, a população-alvo e as barreiras enfrentadas para que a mudança ocorra. Só assim, é possível implantar alternativas baseadas nas evidências concretas, englobando diferentes fatores e intervindo nos quatro domínios que contemplam a prática de atividade física. Desta forma, o objetivo do estudo foi analisar o nível de atividade física habitual dos funcionários administrativos (exceto docentes e trabalhadores de manutenção) da Unesp – Rio Claro, através do questionário Baecke adaptado por Florindo e colaboradores. . Além disso, medidas antropométricas foram coletadas para fornecimento de dados sobre a composição corporal dos mesmos. A partir das respostas dos questionários observou-se que a maioria dos funcionários é moderadamente ativa (58%), quando se trata do nível de atividade física total. O nível de atividade física de lazer é o maior responsável por aumentar o nível de atividade física habitual, no entanto menos de 10% dos sujeitos, cerca de 7 funcionários, foram considerados muito ativos neste domínio. Quanto à composição corporal, grande parte dos sujeitos apresenta-se com sobrepeso, estando com a média do IMC acima da população de Rio Claro. No nível de atividade de física de locomoção, mais de 60% ou aproximadamente 56 sujeitos foram identificados como insuficientemente ativos. Com relação ao gênero, as mulheres são mais inativas no deslocamento em relação aos homens. Tendo em vista a problemática que comportamentos de risco afetam...(Resumo completo, clicar acesso eletrônico abaixo)

Physical activity is associated with lower cardiovascular disease risk factors, being cardiorespiratory fitness a major component of physical activity health related. Body fatness and sarcopenia are related to sedentary lifestyle leading to proinflammatory stress and lower cadiorespiratory capacity. This study aimed correlates C-reactive protein with cardiorespiratory fitness, analyzing the influences of anthropometrics variables and metabolic syndrome (MS) presence. the cross-sectional retrospective study included baseline data of 194 adults (62 male and 132 female), 53,74 ± 8,77 years, clinically and ethically selected for a lifestyle modification program. Total cholesterol (TC) and cholesterol lipoprotein fractions, triglycerides (TG) and glucose was dosed by dry chemistry (Vitros® system, Johnson & Johnson). Blood leukocytes was quantified by automatic cell counter (Coulter ABX®, Horiba). LDL-cholesterol was obtained by Friedwald formula. Serum ultrasensitive C-reactive protein (US-CRP) was accessed by the immunochemoluminescence method (Immulite 2000®, DPC Medlab). Weight, height, body mass index (BMI) and waist circumference (WC) were measured. Muscular mass and fat mass were obtained by bioelectrical impedance analysis (impedancemeter Quantum BIA-101Q®, Clinton Township). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Balke protocol). The metabolic syndrome was diagnosed according NCEP – ATP III (2001), following recommendations of American Diabetes Association (2004). Pearson’s correlation crude and adjusted for confounders variables with p<0,05. The prevalence of MS was 30.4%. Crude correlation shows hsCRP was correlated inverse and significantly with VO2max (r= -0.21; p=-0.003) ...(Complete abstract click electronic access below)

Introduction: Loss of muscle strength may represent a burden on everyday tasks significantly compromising the quality of life for mastectomy patients. In addition to the reduced strength of the upper limb, has been shown in mastectomy patients and difficulties in reducing grip. Objectives: To analyze the possible differences in grip strength among women undergoing breast cancer surgery and to compare the body composition. Methods: In the control group (CG n = 46) women participated in the community of FCT / UNESP aged 35 to 70 years without acute orthopedic pathologies. In the experimental group (EG n = 49) participated in women undergoing surgery for breast cancer, without bilateral lymphedema and independent of time and type of surgery. Were evaluated by dynamometer, by Dual Energy X-ray absorptiometry (DEXA) and physical assessment. Results: We observed significant differences in grip strength (p = 0.000), when the group after mastectomy compared with the control group and the radical mastectomy surgery left and quandrandectomia left (p = 0.004). Regarding the presence of lymphedema, statistical difference was observed in the composition of lean mass and trunk fat (p = 0.05). Conclusion: The results of this study suggest that the experimental group are lower grip strength and trunk lean body mass when compared with the control group. The experimental group showed higher values of fat mass when there was presence of lymphedema

Exercise, in general have the ability to promote health, reduce loss of physical fitness, reduce declines in body composition and prevent disease, and promote improvements in athletic performance, and that's consensual today. Through analysis of body composition and physical fitness, you can diagnose the possible individuals at risk of developing diseases, and fractures caused by falls in the elderly. The DXA tests were used (densitometry by dual beam X-ray) to assess body composition and regional, 1 RM test to evaluate the maximum strength and girth measurements, diameters and skin folds in order to analyze the balance of power muscle with both body composition as regional. The results showed that the variance in bone mass between older content related to the change in the maximum muscular strength of the upper and lower limbs, but the force values are not related to increased muscle mass. The development of muscle strength fulfills a dual function in aging which is to maintain or reduce the rate of loss of lean body mass, and also so the body bone health

Introduction: Osteoarthritis, osteoarthrosis or degenerative joint disease characterized by progressive loss of articular cartilage, pain, changes in subchondral bone, osteophyte formation and proliferation. Age, bone mineral density, joint instability, excess weight among others, are risk factors. Methods: To check the influence os physical exercise in patients with the disease were evaluated 39 patients over 50 years, both genders, with clinical and / or radiographic osteoarthritis were divided into experimental group (EG) and control group (CG). EG performed regular physical activity (aerobics) three times a week for four months, while CG was submitted to physical therapy painkiller in the same period. We analyzed demographics, BMI, basal metabolic rate and percentage of fat mass. Results: The results showed that regular physical activity reduced the body fat, but because of their characteristics and low-impact aerobics was not observed consistent benefits in muscle component. However, compared with the CG demonstrated a positive impact on other parameters of body composition.
