    Aptidão física e estado nutricional dos indígenas Khisedje, Parque Indígena do Xingu
    (Universidade Federal de São Paulo (UNIFESP), 2013) Tsutsui, Mario Luiz da Silva [UNIFESP]; Gimeno, Suely Godoy Agostinho [UNIFESP]; http://lattes.cnpq.br/8795620569662647; http://lattes.cnpq.br/3764283477437612
    O objetivo dessa investigação foi verificar a existência de associação entre aptidão física, atividade física (AF) e o estado nutricional dos indígenas Khisêdjê que vivem no Parque indígena do Xingu, de ambos os sexos e com idade ≥ 20 anos. Para tal, em estudo transversal cuja coleta de dados se deu nos anos de 2010 e 2011, obtiveram-se informações relativas a variáveis demográficas (sexo e idade), aptidão física (capacidade cardiorrespiratória (CC), força, resistência muscular (RM) e flexibilidade), atividade física (contador de passos – pedômetro) e estado nutricional (índice de massa corpora (IMC) e perímetro de cintura (PC). Participaram do estudo 166 indígenas (87,4% do total de sujeitos elegíveis). A existência relação entre as variáveis de interesse foi avaliada pela estatística qui-quadrado (variáveis categóricas) ou pelo teste t de Student (variáveis quantitativas). Foram consideradas como estatisticamente significantes aquelas relações cujo valor de p foi < 0,05. Entre os participantes, 40% era do sexo feminino (n=66). A média de idade foi de 38,4 anos (desvio padrão = 14,6 anos). Em relação à aptidão física, observou-se que a maior parte dos indígenas apresentou bom desempenho em praticamente todos os testes com exceção do teste de força, onde apenas 1% dos participantes apresentou desempenho bom. Entre aqueles que participaram da avaliação de AF com o pedômetro, 67,15% foram classificados como muito ativos ou plenamente ativos. A prevalência de sobrepeso ou obesidade foi de 50,0%, enquanto que a de obesidade central (OC) foi de 39,2%. Entre as variáveis indicativas do grau de aptidão física, apenas a CC associou-se significativamente ao IMC (p = 0,014), enquanto que a presença de OC associou-se com as variáveis de CC (p < 0,001), teste de flexibilidade (p=0,034), teste de RM de tronco (p=0,036) e com o número médio de passos/dia (p = 0,005). Esses resultados indicam que apesar da alta prevalência de excesso de peso e de obesidade central observada entre os Khisêdjê, esses indivíduos possuem bons níveis de aptidão física e AF. A ausência de associação da AF e da maioria das variáveis de aptidão física com o estado nutricional explica–se, pelo menos em parte, pela rotina diária que impõe aos Khisêdjê, para sua subsistência (agricultura, caça e pesca, por exemplo), um estilo de vida ativo.

    Boys With Duchenne Muscular Dystrophy: 1-Year Locomotor Changes in Relation to a Control Group
    (Sage Publications Inc, 2018) Martini, Joyce; Caromano, Fatima Aparecida; Carvalho, Eduardo Vital; Goya, Priscila Albuquerque; Hayasaka, Rosana Massae [UNIFESP]; Nakazune, Silvia [UNIFESP]; Favero, Francis Meire [UNIFESP]; Voos, Mariana Callil
    We compared the timed performance and compensatory movements of 32 boys (mean age = 10.0 years) with Duchenne muscular dystrophy (DMD) and 38 healthy boys (mean age = 9.2 years) on 10-meter walking and four-step stair work (climbing and descending). Dependent measures were digital scores on the Functional Evaluation Scale for DMD obtained by watching the boys on film. Groups were compared initially and after 6 and 12 months, using General Linear Models analysis (for two groups and three assessments). Results showed no significant timed performance differences between groups on 10-m walking at the initial assessment

    (Sociedade Brasileira de Medicina do Exercício e do Esporte, 2013-10-01) Grande, Antonio José [UNIFESP]; Silva, Valter [UNIFESP]; Manzatto, Luciane; Rocha, Túlio Brandão Xavier; Martins, Gustavo Celestino; Vilela Junior, Guanis de Barros; Universidade Metodista de Piracicaba; Universidade Federal de São Paulo (UNIFESP); Universidade Estadual de Londrina; Faculdades Integradas Pitágoras de Montes Claros
    INTRODUCTION: About one-third of the day goes on in the workplace. Therefore, strategies that benefit the quality of life of workers become important. OBJECTIVE: To investigate determinants of quality of life after three months of workers' health promotion programs. METHODS: An experimental design was used to verify the quality of life outcomes of 190 workers. The interventions lasted three months. Company A received the exercise program, posters with recommendations on health and quality of life and computer software; Company B received only an exercise program; Company C received posters with recommendations on health and quality of life and computer software, Company D was the control. All assessments of the quality of work life occurred through the questionnaire QVS-80. Data were analyzed through descriptive statistics, the Z test and Cronbach's alpha test. RESULTS: The main factors that interfered in the quality of life were: physical activity focused on aesthetics, physical fitness, smoking, physical activity recommended by a doctor, sitting time, family life, sleep quality, income. Comparing national data to the present study for all chronic diseases self-reported, statistically significant differences were observed. Physical activity for aesthetic reasons is the variable that most negatively influences on the perception of quality of life. CONCLUSION: These data help to reflect on the importance of combined strategies such as physical activity implementation and the understanding on the lifestyle components in the workplace.

    Efeito do uso de meia elástica sobre os níveis dos biomarcadores de lesão muscular em atletas de voleibol após atividade física
    (Sociedade Brasileira de Angiologia e de Cirurgia Vascular (SBACV), 2011-12-01) Figueiredo, Marcondes [UNIFESP]; Figueiredo, Matheus Fidélis; Penha-silva, Nilson; Universidade Federal de São Paulo (UNIFESP); Universidade Federal de Uberlândia Faculdade de Medicina; UFU Instituto de Genética e Bioquímica
    OBJECTIVE:To assess plasma levels of muscle soreness biomarkers, namely creatine kinase, lactate dehydrogenase, and myoglobin, in professional volleyball players following anaerobic exercise with and without the use of elastic stockings. METHODS: Ten female volleyball players aged 18 to 25 years-old were assessed with and without below-knee 20 to 30 mmHg compression stockings (Sport Active®, Venosan, Abreu e Lima, Brazil). Biomarker levels were assessed at three different moments: M0, early in the morning, with the athletes at rest, not using elastic stockings; M1, early in the morning, following a bout of exercise using elastic stockings; M2, seven days later, following the same bout of exercise, however not using elastic stockings. The Borg scale was used after each series of exercise to evaluate the physical effort. RESULTS: The means values obtained for creatine kinase and lactate dehydrogenase were, respectively, 117.7±40.2 and 134.2±11.3 U/L at M0; 138.2±47.2 and 157.9±10.1 U/L at M1; and 161.3±59.9 and 177.2±18.8 U/L at M2. The mean values obtained for myoglobin were 31.5±6.5; 34.9±5.6 and 38.6±12.6 µg/L at the moments M0, M1 and M2, respectively. Statistically significant differences were observed between M1 and M2 (Tukey) for creatine kinase (p=0.0007) and lactate dehydrogenase (p=0.000), but not for myoglobin (p=0.1135). Borg scale scores obtained at M1 and M2 were, respectively, 17.8 and 18.2, without statistically significant differences between them (Wilcoxon). CONCLUSION: The use of elastic stockings was associated with lower plasma levels of biomarkers of muscle injury after exercise.

    The effectiveness of a physical activity and nutrition education program in the prevention of overweight in schoolchildren in Criciuma, Brazil
    (Nature Publishing Group, 2013-11-01) Silva, L. S. M. da; Fisberg, M. [UNIFESP]; Souza Pires, M. M. de; Nassar, S. M.; Sottovia, C. B.; Univ Extremo Catarinense; Universidade Federal de São Paulo (UNIFESP); Universidade Federal de Santa Catarina (UFSC); Cooper Inst
    BACKGROUND/OBJECTIVES: the objectives of this study were to evaluate nutritional status, aptitude and physical activity at the beginning and end of the nutrition education and physical activity intervention program as compared with a control group.METHODS: We conducted a 28-week quasi-experimental study involving 238 students (108 in the intervention group (IG) and 130 in the control group (CG)). the IG participated in curricular and extracurricular activities for nutrition education (50 min once a week) and physical activity (50 min twice a week), and the CG participated only in curricular activities. Nutritional status was determined using body mass index, according to the WHO 2007 curve. the effect of the intervention program was evaluated using a model of generalized estimating equations.RESULTS: Among overweight students, a greater reduction in percentile of BMI was observed in the IG (64.6%) compared with CG (36.4%), P=0.001. Improvement in nutritional status occurred in 26.2% of IG versus 10.4% of CG (P=0.014). the IG showed a significant increase in the amount of moderate or vigorous physical activity (P=0.012), whereas in the control group the increase was not significant (P=0.810). in three physical fitness tests, the IG showed significant improvements in performance (P<0.001), whereas the control group's performance was worse in the final evaluation.CONCLUSIONS: the intervention program had a positive effect on overweight, with significant improvements in nutritional status and physical fitness.

    Geoprocessing via Google Maps for Assessing Obesogenic Built Environments Related to Physical Activity and Chronic Noncommunicable Diseases: Validity and Reliability
    (Multi-science Publ Co Ltd, 2015-03-01) Silva, Valter [UNIFESP]; Grande, Antonio Jose; Rech, Cassiano Ricardo; Peccin, Maria Stella [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Univ Extremo Sul Catarinense; Universidade Federal de Santa Catarina (UFSC)
    This study analyzes the reliability and validity of obesogenic built environments related to physical activity and chronic noncommunicable diseases through Google Maps in a heterogeneous urban area (i.e., residential and commercial, very poor and very rich) in Sao Paulo (SP), Brazil. There are no important differences when comparing virtual measures with street audit. Based on Kappa statistic, respectively for validity and reliability, 78% and 80% of outcomes were classified as nearly perfect agreement or substantial agreement. Virtual measures of geoprocessing via Google Maps provided high validity and reliability for assessing built environments.

    Implications of ketogenic diet on weight gain, motor activity and cicatrization in Wistar rats
    (Informa Healthcare, 2013-02-01) Peres, Rogerio Correa; Nogueira, Danilo Barion; Guimaraes, Gabriela de Paula; Costa, Elizabete Lourenco da; Ribeiro, Daniel Araki [UNIFESP]; Univ Catolica Santos; Universidade Federal de São Paulo (UNIFESP)
    The ketogenic diet (KD) was initially developed for the treatment of pharmacoresistant epilepsy and a possible alternative for the obesity treatment, dyslipidemia, resistance to insulin, and nonalcoholic steatosis. However, few studies evaluate the diet effects in rats behavior or cicatrization. the objective of this work was to analyze the influence of the ketogenic diet on the weight gain, emotional behavior of the rats submitted to experimental models such as elevated plus maze (EPM) and open field (OF). the cicatrization time and leukocyte differentiations were also observed. Twenty male Wistar rats of two months age were divided into two groups. One was submitted to ketogenic diet (KD), and the control group (Co) was fed on commercial rations. After 7 days, the animals were weighed and submitted to EPM and OF. A small surgical incision was made and their blood was collected to a leukocyte count. It was verified that the rats from the KD presented less weight gain as compared with the rats from the Co (p < 0.05). the KD did not reveal differences on the behavior measures in the EPM model, but in the of presented an ambulatory activity significantly bigger. the animals from the KD presented a cicatrization significantly better than Co after 72 h (p = 0.0035) and 96 h (p < 0.1). There was no difference between the groups for leukocyte count. Our results suggest that the KD can interfere on rats deambulation in animal models and improve the cicatrization response.

    Inatividade física avaliada por acelerometria triaxial e fatores associados em adultos: resultados do estudo epimov
    (Universidade Federal de São Paulo (UNIFESP), 2016) Sperandio, Evandro Fornias [UNIFESP]; Dourado, Victor Zuniga [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    CONTEXT AND OBJECTIVES: Accelerometry provides objective measurement of physical activity levels, but is unfeasible in clinical practice. Thus, we aimed to identify physical fitness tests capable of predicting physical inactivity among adults. DESIGN AND SETTING: Diagnostic test study developed at a university laboratory and a diagnostic clinic. METHODS: 188 asymptomatic subjects underwent assessment of physical activity levels through accelerometry,ergospirometry on treadmill, body composition from bioelectrical impedance, isokinetic muscle function, postural balance on a force platform and six-minute walk test. We conducted descriptive analysis and multiple logistic regression including age, sex, oxygen uptake, body fat, center of pressure, quadriceps peak torque, distance covered in six-minute walk test and steps/day in the model, as predictors of physical inactivity. We also determined sensitivity (S), specificity (Sp) and area under the curve of the main predictors by means of receiver operating characteristic curves. RESULTS: The prevalence of physical inactivity was 14%. The mean number of steps/day (≤ 5357) was the best predictor of physical inactivity (S = 99%; Sp = 82%). The best physical fitness test was a distance in the six-minute walk test and ≤ 96% of predicted values (S = 70%; Sp = 80%). Body fat > 25% was also significant (S = 83%; Sp = 51%). After logistic regression, steps/day and distance in the six-minute walk test remained predictors of physical inactivity. CONCLUSION: The six-minute walk test should be included in epidemiological studies as a simple and cheap tool for screening for physical inactivity.

    Intra-nigral MPTP lesion in rats: Behavioral and autoradiography studies
    (Elsevier B.V., 2005-10-01) Perry, J. C.; Hipolide, D. C.; Tufik, S.; Martins, R. D.; Da Cunha, C.; Andreatini, R.; Vital, MABF; Univ Fed Parana; Universidade Federal de São Paulo (UNIFESP)
    The present study investigated the motor response and possible changes in binding to D-1 and D-2 receptors after intra-nigral 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) infusion on rats. the results indicated that MPTP-lesioned rats exhibited a significant reduction in locomotion and rearing frequencies observed in an open field 24 h after surgery. However, at 7 and 14 days after surgery the MPTP-lesioned rats showed a significant increase in locomotion in comparison to the control groups, as well as a decrease in immobility time. in addition, 21 days after surgery the behavioral measurements were unaltered by these procedures. Moreover, latency in initiating movement and catalepsy were unchanged by this neurotoxin on the same days of observation. An autoradiography approach indicated that there was a reduction in [H-3]SCH 23390 binding in substantia nigra pars compacta (SNpc), substantia nigra pars reticulata (SNpr) and ventrolateral striatum in MPTP-treated rats 21 days after the surgery. [H-3]raclopride binding remained unaltered by the MPTP treatment. These results suggest that compensatory plastic changes occur in D I dopamine receptors after partial lesion of nigral dopaminergic neurons. These alterations might be related to the occurrence and recovery of motor impairment observed in MPTP-lesioned rats. (c) 2005 Elsevier Inc. All rights reserved.

    Physical Activity Interventions in Faith-Based Organizations: A Systematic Review
    (Sage Publications Inc, 2018) Parra, Maira Tristao [UNIFESP]|Porfirio, Gustavo J. M. [UNIFESP]; Arredondo, Elva M.; Atallah, Alvaro N. [UNIFESP]
    Objective: To review and assess the effectiveness of physical activity interventions delivered in faith-based organizations. Data Source: We searched the Cochrane Library, DoPHER, EMBASE, LILACS, MEDLINE, PsycINFO, WHO ICTRP, and Clinicaltrials.gov databases until January 2016, without restriction of language or publication date. Study Inclusion and Exclusion Criteria: Randomized and nonrandomized controlled trials investigating physical activity interventions for adults delivered in faith-based organizations. Data Extraction: Two independent reviewers extracted data and assessed study methodological quality. Data Synthesis: We used relative risk and mean difference with 95% confidence interval to estimate the effect of the interventions on measures of physical activity, physical fitness, and health. Results: The review included 18 studies. Study participants were predominantly female, and the majority of trials were conducted in the United States. Study heterogeneity did not allow us to conduct meta-analyses. Although interventions delivered in faith-based organizations increased physical activity and positively influenced measures of health and fitness in participants, the quality of the evidence was very low. Conclusion: Faith-based organizations are promising settings to promote physical activity, consequently addressing health disparities. However, high-quality randomized clinical trials are needed to adequately assess the effectiveness of interventions delivered in faith-based organizations.

    Relationship between muscle strength and motor function in Duchenne muscular dystrophy
    (Assoc Arquivos Neuro- Psiquiatria, 2016) Nunes, Milene F.; Hukuda, Michele E.; Favero, Francis M. [UNIFESP]; Oliveira, Acary B. [UNIFESP]; Voos, Mariana C.; Caromano, Fatima A.
    Measuring muscle strength and motor function is part of Duchenne muscular dystrophy (DMD) assessment. However, the relationship between these variables is controversial. Objective: To investigate the relationship between muscle strength and motor function and between these variables and age. Method: Muscle strength was measured by Medical Research Council (MRC) scale and motor function, by Motor Function Measure (MFM), in 40 non-ambulatory patients. Spearman tests investigated the relationships between muscle strength, motor function and age. Results: Total MRC and MFM scores were strongly related to each other (r = 0.94
