Background: Patients with schizophrenia have lower longevity than the general population as a consequence of a combination of risk factors connected to the disease, lifestyle and the use of medications, which are related to weight gain.Methods: A multicentric, randomized, controlled-trial was conducted to test the efficacy of a 12-week group Lifestyle Wellness Program (LWP). the program consists of a one-hour weekly session to discuss topics like dietary choices, lifestyle, physical activity and self-esteem with patients and their relatives. Patients were randomized into two groups: standard care (SC) and standard care plus intervention (LWP). Primary outcome was defined as the weight and body mass index (BMI).Results: 160 patients participated in the study (81 in the intervention group and 79 in the SC group). On an intent to treat analysis, after three months the patients in the intervention group presented a decrease of 0.48 kg (CI 95% - 0.65 to 1.13) while the standard care group showed an increase of 0.48 kg (CI 95% 0.13 to 0.83; p=0.055). At six-month follow-up, there was a significant weight decrease of -1.15 kg, (CI 95% -2.11 to 0.19) in the intervention group compared to a weight increase in the standard care group (+0.5 kg, CI 95% -0.42-1.42, p=0.017).Conclusion: in conclusion, this was a multicentric randomized clinical trial with a lifestyle intervention for individuals with schizophrenia, where the intervention group maintained weight and presented a tendency to decrease weight after 6 months. It is reasonable to suppose that lifestyle interventions may be important long-term strategies to avoid the tendency of these individuals to increase weight.

(Abrasco, 2017) de Moraes Ferrari, Gerson Luis [UNIFESP]; Araujo, Timoteo; Oliveira, Luis Carlos; Rodrigues Matsudo, Victor Keihan; Mire, Emily; Barreira, Tiago; Tudor-Locke, Catrine; Katzmarzyk, Peter T.
The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI-defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1-minute cadence differed significantly across BMI and % BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.

Análise da associação de atividade física à síndrome metabólica em estudo populacional de nipo-brasileiros
(Sociedade Brasileira de Endocrinologia e Metabologia, 2006-12-01) Doro, Antonio Roberto [UNIFESP]; Gimeno, Suely Godoy Agostinho [UNIFESP]; Hirai, Amélia Toyomi [UNIFESP]; Franco, Laercio Joel [UNIFESP]; Ferreira, Sandra Roberta Gouvea [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)
Sedentary behavior-related diseases can be prevented by lifestyle changes. Part of the cardiovascular benefits of physical activity (PA) may be due to low-grade inflammation. This study describes the PA of a population of Japanese and analyses its association with metabolic syndrome (MS) adjusted a number of variables. This was based on a database previously created following a population-based study of Japanese-Brazilians. 1,330 subjects aged > 30 years, of both sexes, living in Bauru, were included and they were submitted to interviews, being obtained sociodemographic, health, physical activity and dietary data, as well as clinical and laboratory data. Physical activity assessment focused on activities during work and leisure times. Diagnosis of MS was based on an adaptation of NCEP criteria for Asians. Non-conditional logistic regression had MS as the dependent variable. Men (46.1%) and women showed similar mean ages (57.0 ± 12.8 and 56.9 ± 12.2 years, respectively). A slight preponderance of females was observed. Men had a higher level of education and more frequently were smokers (p< 0.001); their mean values of BMI, waist and blood pressure (p< 0.001) were higher than the women s. For both sexes, the majority referred light and moderate activities (81.2% of men and 86.6% of women). As far as work time is concerned, 87.8% of men classified their effort as light or moderate versus 96.1% of women. Distribution by PA levels showed that women were always less active than men (p= 0.01). Stratifying by the presence of MS, men and women with MS were significantly older and showed greater anthropometric values. Considering the walking duration for work, there was a tendency of shorter periods among those with MS (p< 0.078). As expected, subjects with MS showed significantly higher levels of blood pressure, plasma glucose, lipids and HOMA-IR when compared to those without MS. HDL levels were lower in the MS group, being significant for the female sex. The mean values of CRP were higher in subjects with MS. In logistic regression, age, BMI, HOMA-IR and CRP were shown to be independently associated with MS, but not parameters used to measure physical activity. Our findings do not allow to state that physical inactivity is associated with MS in a Japanese-Brazilian population. High frequencies of physical inactivity should have contributed to the negative findings concerning protective effects of physical activity. The association of MS and serum CRP favors the hypothesis that a low-grade inflammatory state may participate in this syndrome.

(Sociedade Brasileira de Pediatria, 2013-08-01) Ferrari, Gerson Luis de Moraes [UNIFESP]; Bracco, Mario Maia [UNIFESP]; Matsudo, Victor Keihan Rodrigues; Fisberg, Mauro [UNIFESP]; Centro de Estudos do Laboratório de Aptidão Física de São Caetano do Sul; Universidade Federal de São Paulo (UNIFESP); Sociedade Beneficente Israelita Brasileira Albert Einstein Hospital Israelita Albert Einstein
OBJECTIVE: To compare the changes in cardiorespiratory fitness in evaluations performed every ten years since 1978/1980, according to the nutritional status and gender of students in the city of Ilhabela, Brazil. METHODS: The study is part of the Mixed Longitudinal Project on Growth, Development and Physical Fitness of Ilhabela. The study included 1,291 students of both genders, aged 10 to 11 years old. The study periods were: 1978/1980, 1988/1990, 1998/2000, and 2008/2010. The variables analyzed were: body weight, height, and cardiorespiratory fitness (VO2max -L.min-1 and mL.kg-1.min-1) performed using a submaximal progressive protocol on a cycle ergometer. Individuals were classified as normal weight and overweight according to curves proposed by the World Health Organization of body mass index for age and gender. Analysis of variance (ANOVA) with three factors followed by the Bonferroni method were used to compare the periods. RESULTS: The number of normal weight individuals (61%) was higher than that of overweight. There was a significant decrease in cardiorespiratory fitness in both genders. Among the schoolchildren with normal weight, there was a decrease of 22% in males and 26% in females. In overweight schoolchildren, males showed a decrease of 12.7% and females, of 18%. CONCLUSION: During a 30-year analysis with reviews every ten years from 1978/1980, there was a significant decrease in cardiorespiratory fitness in schoolchildren of both genders, which cannot be explained by the nutritional status. The decline in cardiorespiratory fitness was greater in individuals with normal weight than in overweight individuals.

(Associação Paulista de Medicina - APM, 2009-07-01) Sarkis, Karin Sedó; Salvador, Mariana Barbieri; Pinheiro, Marcelo de Medeiros [UNIFESP]; Silva, Raissa Gomes [UNIFESP]; Zerbini, Cristiano Augusto de Freitas; Martini, Lígia Araújo; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)
CONTEXT AND OBJECTIVES: Osteoporosis has frequently been observed in patients with rheumatoid arthritis. The present study was undertaken in order to evaluate factors associated with osteoporosis among women with rheumatoid arthritis. DESIGN AND SETTING: Cross-sectional study, carried out in a public hospital in São Paulo. METHODS: The participants were 83 women with rheumatoid arthritis (53.7 ± 10.0 years old). Bone mineral density (BMD) and body composition were measured by dual energy X-ray absorptiometry. The patients were divided into three groups according to BMD: group 1, normal BMD (n = 24); group 2, osteopenia (n = 38); and group 3, osteoporosis (n = 21). Tests were performed to compare differences in means and correlations, with adjustments for age, duration of disease and cumulative corticosteroid. The relationships between clinical factors, physical activity score, dietary intake, body composition and biochemical parameters were analyzed using linear regression models. RESULTS: Mean calcium, vitamin D and omega-6 intakes were lower than the recommendations. Associations were found between BMD and age, disease duration, parathyroid hormone concentration and fat intake. The linear regression model showed that being older, with more years of disease and lower weight were negatively correlated with BMD [Total femur = 0.552 + 0.06 (weight) + 0.019 (total physical activity) - 0.05 (age) - 0.003 (disease duration); R² = 48.1; P < 0.001]. CONCLUSION: The present study indicates that nutritional factors and body composition are associated with bone mass in women with rheumatoid arthritis.

Background: There is evidence that if a health professional is active and has a healthy diet, he/she is more likely to advise patients about the benefits of physical activity and healthy eating the aims of this study were to: (1) describe the personal physical activity, consumption of fruits and vegetables behaviors and nutritional status of community health workers; (2) evaluate the association between knowledge, delivery of preventive counseling and personal behaviors among community health workers.Methods: This was a cross-sectional study conducted in a nationally sample of health professionals working in primary health care settings in Brazil in 2011. This survey was part of the second phase of the Guide for Useful Interventions for Activity in Brazil and Latin America project, and data were collected through telephone interviews of 269 community health workers from the Unified Health Care system of Brazil. We applied questionnaires about personal reported behaviors, knowledge and preventive counseling in physical activity and consumption of fruits and vegetables. We calculated the prevalence and associations between the variables with logistic regression.Results: the proportion of community health workers that practiced 150 minutes per week of physical activity in leisure time or transportation was high (64.9%). Half of community health workers were overweight and only 26.2% reported consuming five portions/day of fruits or vegetables. Most community health workers reported counseling about physical activity for more than six months (59.7%), and most were not knowledgeable of the fruits and vegetables and physical activity recommendations. Meeting the fruits and vegetables recommendations was associated with correct knowledge (OR = 4.5; CI95% 1.03; 19.7), with reporting 150 minutes or more of physical activity per week (OR = 2.0; CI95% 1.03; 3.7) and with reporting physical activity in leisure time (OR = 2.0; CI95% 1.05; 3.6). Regular physical activity counseling was associated with reporting 10-149 minutes per week (OR = 3.8; CI95% 1.1; 13.3) and with more than 150 minutes of physical activity per week (OR = 4.9; CI95% 1.5; 16.5).Conclusion: Actions to promote physical activity and healthy eating and to improve knowledge among community health workers within the health care system of Brazil could have a potential positive influence on delivery of preventive counseling to patients on this topic.

Doenças associadas ao sedentarismo podem ser prevenidas por mudanças no estilo de vida. Parte dos benefícios cardiovasculares da atividade física (AF) poderiam advir de menor grau de inflamação. Este estudo descreve a AF de uma população de origem japonesa e analisa sua associação à síndrome metabólica (SM), ajustada para diversas variáveis. Baseou-se em banco de dados previamente constituído a partir de estudo de base populacional em nipo-brasileiros. Foram incluídos 1330 indivíduos 􀀀 ambos os sexos, residentes em Bauru, submetidos a entrevistas, sendo obtidos dados sócio-demográficos, de saúde, AF e de dieta, além de exames médico e laboratoriais. A avaliação da AF enfocou atividades no trabalho e nas horas vagas. O diagnóstico de SM foi baseado em adaptação para asiáticos dos critérios do NCEP. Empregou-se regressão logística, tendo a SM como variável resposta. Homens (46,1%) e mulheres apresentaram médias de idade semelhantes (57,0±12,8 e 56,9±12,2 anos, respectivamente). Houve leve predomínio do sexo feminino. Os homens apresentavam grau de instrução mais elevado e mais freqüentemente eram fumantes (p<0,001); seus valores médios de IMC, cintura e de pressão arterial (p<0,001) foram superiores aos das mulheres. Para ambos os sexos, a maioria referia praticar atividades de intensidade leve ou moderada nas horas vagas (81,2% dos homens e 86,6% das mulheres). Quanto ao esforço do trabalho, 87,8% dos homens classificaram seu esforço como leve ou moderado, contra 96,1% das mulheres. A distribuição por níveis de AF invariavelmente revelou que as mulheres eram mais inativas (p=0,01). Estratificando-se pela presença da SM, as mulheres e homens com SM eram significantemente mais velhos e apresentavam maiores valores antropométricos. Considerando a duração da caminhada ao trabalho, notou-se tendência a tempo menor entre aqueles com SM (p<0,078). Conforme esperado, indivíduos com SM apresentaram níveis significantemente maiores de pressão arterial, glicemia, lípides e HOMA-IR quando comparado aos sem SM. O HDL foi menor no grupo com SM, sendo significante no sexo feminino. Os valores médios da PCR foram maiores nos indivíduos com SM. Na regressão logística, a idade, IMC, HOMA-IR e PCR se associaram independentemente à SM, o que não ocorreu com os parâmetros usados para mensurar AF. Nossos achados não permitem afirmar que a inatividade física associa-se à presença de SM numa população nipobrasileira, mas sim um estado inflamatório sub-clínico. Limitações de ordem metodológica devem ter contribuído para achados negativos quanto a efeitos protetores da AF.

A atividade física em usuários acima de 60 anos de uma unidade básica de saúde: nível, prática e aconselhamento
(Universidade Federal de São Paulo, 2017-09-29) Nogueira, Viviane Aparecida Iglecias [UNIFESP]; Gouvêa, Lélia Cardamone [UNIFESP]; http://lattes.cnpq.br/1669637254047655; http://lattes.cnpq.br/1240021677614546
The increase in the elderly population has become a challenge for health policies. In this context, the objective of this research was to investigate the level and practice of physical activity in the population above 60 years of age, residents of the region and users of the UBS (Basic Health Unit) Rudge Ramos, including whether there was professional guidance and the motive that led these seniors to its practice. This is a cross-sectional, descriptive study with a quantitative approach. Questionnaires were applied to 190 individuals older than 60 years, accompanied by the Family Health Strategy, who received home visits and had consultations at the UBS. Three questionnaires were used: 1 - Based on the record of the community health agents, to characterize the sample; 2 - International Physical Activity Questionnaire (IPAQ) - short version, to assess the level of physical activity; and 3 - Identification of the practice that the user develops and if they have received recommendation for the practice of physical activity from some of the health agents. For the statistical analysis, the chi-square test and the Fisher's exact test were used, with a significance level of p≤0.05. The results showed that the sample consisted mainly of female individuals aged between 60 and 80 years, with elementary education, income of 1 to 2 minimum wages, the majority do not have a formal job and have one or more problems, and have a positive perception of their health. They were classified as physically active (48.9%), the most practiced activity was walking in parks and streets. And (98.5%) stated that they practice physical activity motivated by the improvement of their health. Of the total, (60.5%) reported that they received counseling for the physical activity of some UBS health worker and the professional who advised them the most was the medical professional in (64.5%). The positive role of physical activity counseling was demonstrated, since in the active group (67.4%) they were advised against (53.6%) of the insufficiently active and / or sedentary group, and this difference found between the groups was significant. It is considered that the results of the present study have demonstrated that the level of physical activity and the counseling received by the elderly was superior to those described in the literature, but it is still less than expected, since half of the elderly responding to the questionnaire did not reach the recommendations physical activity to promote positive changes in health. It should also be noted that the results of this research are delimited to a specific region with little resources. We emphasize that physical activity counseling by health professional teams can play a positive role in raising awareness and improving the health of the elderly population.

Atividade física precoce e a hipótese de reserva neural: análise dos níveis corticais e hipocampais de fator neurotrófico derivado do encéfalo (BDNF), de hormônio adrenocorticotrófico (ACTH) e de corticoesterona ao longo da vida sedentária de ratos que foram fisicamente ativos na adolescência
(Universidade Federal de São Paulo (UNIFESP), 2018-10-25) Carvalho, Andrea Dominguez [UNIFESP]; Silva, Sergio Gomes da [UNIFESP]; http://lattes.cnpq.br/6571529192321274; http://lattes.cnpq.br/1021349849771222; Universidade Federal de São Paulo (UNIFESP)
Purpose: There are reports that life experiences at early ages such as physical activity in childhood and adolescence can reduce the future risk of brain disorders and enhance lifelong brain functions. However how early physical activity promotes such effects are not well understood. A possible explanation is that physical exercise can stimulate neuronal growth, resulting in a neural reserve which could be extracted throughout the life course. Based in this hypothesis, the present study was designed to investigate the neural reserve induced by early physical activity. To do this, we evaluated the cortical and hippocampal levels of BDNF, ACTH and corticosterone during the aging course of rats submitted to physical exercise during adolescent period. Methods: Thirtyfive male Wistar rats were distributed into exercise (EX, n=18) and control (CTL, n=17) groups. Rats from EX group were submitted to an aerobic exercise program during the 21st and 60th postnatal day (P21P60). Afterward, cortical and hippocampal levels of BDNF, ACTH and corticosterone from the EX and CTL groups were investigated at different life stages: 0 (P60), 30 (P90), 60 (P120) and 90 (P150) days after last exercise session. The BDNF, ACTH and corticosterone levels were quantified by mean of Luminex xMAP system (MAGPIX technology). Results: No change was detected in the cortical and hippocampal levels of ACTH and corticosterone (p > 0.05). After the last physical training session (at P60), it was noted a significant increase of hippocampal BDNF (p < 0.05). However, this effect induced by early exercise was not maintained throughout the sedentary life of rats (ie, BDNF levels returned to control levels at P90 and P120). Conclusion: Our results indicate that changes in hippocampal BDNF levels may occur in rats exercised in youth, especially at P60. However, no persistent and longlasting effect of early physical exercise, which could be related to the neural reserve, was found in this study.

Atividades físicas e barreiras referidas por adolescentes atendidos num serviço de saúde
(Universidade Federal de Santa Catarina, 2011-06-01) Garcia, Leandro Martin Totaro [UNIFESP]; Fisberg, Mauro [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
This study characterized the physical activity and barriers reported by adolescents attending the Physical Education service of the Adolescent Care and Support Center, São Paulo, Brazil. An exploratory study was conducted using anamnesis data from 118 adolescents aged 10 to 19 years seen between April 2005 and June 2008. The following aspects were analyzed according to gender and age group: participation in leisure-time physical activities and physical education classes, physical activity preferences, and barriers to preferred physical activity. Data are reported as frequencies and were compared by Fisher's exact test. Enjoying physical activities was reported by 93.2% of the adolescents, whereas 50.8% did not perform any physical activity during their leisure time. The lack of participation in school physical education classes predominated among older adolescents of both genders. Games and team games were the preferred activities, irrespective of gender or age. The lack of company or friends and the lack of places were the most frequently reported barriers to preferred physical activity. The results highlight the importance of a health service program for adolescents that promotes, guides, and supports a more active lifestyle.

Auto seleção de exercícios físicos para a elaboração de um programa de treinamento físico para adultos por meio de aplicativo para smartphone: estudo qualitativo
(Universidade Federal de São Paulo, 2022-11-18) Guedes, Krom Marsili [UNIFESP]; Dourado, Victor Zuniga [UNIFESP]; http://lattes.cnpq.br/1919368500743497; http://lattes.cnpq.br/4459998928037966; Universidade Federal de São Paulo (UNIFESP)
Nos últimos anos ocorreu aumento significativo dos aplicativos de smartphone que monitoram a atividade física. Além de não oferecerem programas alinhados às recomendações internacionais, frequentemente os exercícios propostos têm alto grau de complexidade para iniciantes e pessoas com maior risco cardiovascular, aumentando o risco de lesões. Portanto, desenvolvimento de novos aplicativos deveria considerar progressão pedagógica dos exercícios de acordo com a aptidão física do usuário, garantindo confiança para realizar a tarefa proposta. Objetivo: O objetivo do presente estudo foi identificar os exercícios físicos preferidos por adultos potenciais usuários de um aplicativo de smartphone para atividade física. O objetivo secundário foi investigar a associação entre fatores de risco cardiovascular e a preferência pelos exercícios de força muscular. Métodos: Este é um estudo observacional transversal, para o qual a coleta de dados se deu por meio de questionário online. A amostra foi composta por 262 indivíduos de ambos os sexos com idade a partir de 20 anos, que utilizam smartphones e não apresentam contraindicações para a prática de atividade física sem supervisão. Dados demográficos e clínicos, nível de atividade física pelo Questionário Internacional de Atividade Física (IPAQ) e estágio de mudança de comportamento para a atividade física foram coletados inicialmente. Após o preenchimento dos questionários, foram apresentados vídeos de exercícios físicos executados ao ar livre, gravados em espaços públicos. Os exercícios foram divididos em 3 categorias: (1) membros inferiores, (2) membros superiores e tronco, e (3) tronco (core). Ao final de cada sequência, os participantes deveriam relatar suas preferências de acordo com o grau de dificuldade percebida e a vontade em executá-los, além de poderem justificar suas escolhas em campos de perguntas abertas. Os dados foram analisados qualitativamente, por análise temática e núvem de palavras, e quantitativamente por meio de regressão logística multivariada. Resultados: De maneira geral os participantes apontaram como preferidos os exercícios de menor dificuldade. Similarmente, as palavras utilizadas com maior frequência nas perguntas abertas foram “fácil” e “facilidade”. Ao contrário do que esperávamos, o número de fatores de risco cardiovascular teve uma associação positiva com a preferência por exercícios considerados intermediários e difíceis (Odds Ratio, 1,82: Intervalo de Confiança de 95%, 1,22 – 2,72). A inatividade física também apresentou associação positiva (3,72: 1,34 – 9,78) para a escolha desse grupo de exercícios. Conclusões: A proporção de escolha por preferência pelos exercícios de mais fácil execução foi maior em todas as diferentes categorias de exercícios. Quando a escolha foi ajustada pelos fatores de risco cardiovascular, os exercícios de maior dificuldade foram os preferidos. Nossos resultados sugerem a participação imprescindível de especialistas em atividade e exercício físicos no desenvolvimento de aplicativos de smartphone nessa área, sobretudo os profissionais de educação física.

(Universidade Federal de São Paulo, 2012-04-10) Orlando, Mariana Martinez [UNIFESP]; Lombardi Júnior, Imperio [UNIFESP]; Peccin, Maria Stella [UNIFESP]; http://lattes.cnpq.br/0428199048138850; http://lattes.cnpq.br/6748923176828764; http://lattes.cnpq.br/1622581944839862; Universidade Federal de São Paulo (UNIFESP)
Introdução: O envelhecimento torna-se um grande desafio para saúde pública, devido a necessidade de encontrar soluções para manter a sobrevida e melhorar a qualidade de vida. A prática de atividade física tem sido uma importante aliada na promoção de saúde e prevenção das doenças relacionadas ao processo de envelhecimento. Objetivo: O objetivo do presente estudo foi avaliar a qualidade de vida, força muscular, equilíbrio e capacidade física de idosos praticantes e não praticantes de atividade física. Casuística e Métodos: Foi realizado um estudo observacional transversal com 74 idosos da cidade de Santos/ SP- Brasil, divididos em dois grupos: praticantes e não praticantes de atividade física. Para a coleta de dados foi utilizado o questionário internacional de atividade física para a classificação dos idosos, para avaliar a qualidade de vida foi utilizado o questionário genérico SF36, a escala de Berg foi utilizada para análise do equilíbrio, para o teste de força muscular foi utilizado a dinamometria e para a avaliação da capacidade física foi utilizado o teste de caminhada de seis minutos. Resultados: Os dados do presente estudo mostram uma diferença significativa na qualidade de vida (p=0,001), força muscular (p=0,001), equilíbrio (p=0,001) e capacidade física (p=0,001) entre os idosos praticantes e não praticantes de atividade física. Os dados demonstram também uma moderada correlação entre os aspectos de qualidade de vida com o equilíbrio (0,513) no grupo praticante de atividade física, e uma forte correlação na qualidade de vida e a capacidade física (r= 0,741) no grupo não praticantes de atividade física. Conclusão: Podemos concluir que os idosos da cidade de Santos que praticam atividade física têm melhor qualidade de vida, força muscular, capacidade física e equilíbrio do que os não praticam de atividade física.

Introdução: A obesidade vem sendo associada ao desenvolvimento de doenças crônicas e problemas no sistema serotoninérgico, tornando necessária a exploração de intervenções como a troca de dieta e treinamento físico. Objetivo: Avaliar o efeito do treinamento físico e da intervenção dietética no sistema serotoninérgico do hipocampo de ratos obesos. Métodos: Utilizou-se 30 ratos Wistar machos, com 8 semanas de vida. Com exceção do grupo controle (CC), os demais animais receberam uma dieta hiperlipídica palatável (DHL) por 20 semanas. Em seguida os ratos obesos foram distribuídos em 4 grupos: Sedentário Hiperlipídica (SHM), Sedentário Dieta (SDM), Treinado Hiperlipídica (THM) e Treinado Dieta (TDM). Os grupos SHM e THM permaneceram recebendo a DHL, enquanto os grupos SDM e TDM passaram a receber dieta padrão e os grupos THM e TDM realizaram um protocolo de exercício combinado. Após a intervenção, foi realizada eutanásia dos animais para avaliação da expressão proteica dos receptores de serotonina 5HT1A e 5HT2C no hipocampo. Resultados: A DHL foi efetiva na indução de obesidade no modelo escolhido. Na etapa de intervenção, a mudança para uma dieta controle foi a principal responsável pela redução da adiposidade visceral, com colaboração do treinamento na redução da gordura gonadal, especificamente. Conclusão: O protocolo de indução à obesidade via dieta se mostrou efetivo, com intervenções de treinamento e dieta agindo de maneira eficaz na redução da adiposidade visceral. Porém, o protocolo de treinamento combinado não afetou as moléculas do sistema serotoninérgico analisadas.

Os baixos níveis de potência aeróbia máxima prejudicam o perfil do estado de humor em indivíduos com epilepsia do lobo temporal
(Academia Brasileira de Neurologia - ABNEURO, 2015-01) Vancini, Rodrigo Luiz [UNIFESP]; Lira, Claudio Andre Barbosa de [UNIFESP]; Andrade, Marília dos Santos [UNIFESP]; Lima, Cristiano de [UNIFESP]; Arida, Ricardo Mario [UNIFESP]
Objetivo: Investigar a correlação entre aptidão cardiorrespiratória e variáveis de estado de humor em indivíduos com epilepsia do lobo temporal (ELT). Método: Indivíduos com ELT (n = 20) e controles saudáveis (C, n = 20) foram avaliados. Administraram-se questionários para avaliar o estado de humor (POMS) e nível de atividade física habitual (BAECKE). Avaliou-se a aptidão cardiorrespiratória por teste incremental máximo. Resultados: Pessoas com ELT apresentaram menor aptidão cardiorrespiratória; elevados níveis de transtornos do humor; e menor nível de vigor, quando comparadas ao grupo C. Observou-se correlação negativa significativa entre os níveis de tensão-ansiedade e a potência aeróbica máxima. Conclusão: O baixo nível de aptidão cardiorrespiratória pode modificar o estado de saúde de indivíduos com ELT e pode ser considerado fator de risco para o desenvolvimento de transtornos de humor.

We evaluated physiological and electroencephalographic responses during a cardiopulmonary exercise test (CPET) in people with epilepsy. Behavioral outcomes of people with epilepsy were also compared with those of healthy controls. Thirty-eight subjects (19 people with epilepsy and 19 controls) participated in this study. Poor outcomes in the behavioral analyses (habitual level of physical activity and quality of life) were observed in the people with epilepsy. With respect to the CPET, VO(2max) (14.6%) and VO(2) at anaerobic threshold (16.1%) were significantly lower in the epilepsy group than in the control group. Although not statistically significant, a decrease in the number of epileptiform discharges was observed between the rest state and exercise (82%) and between the rest state and recovery period (74%). in conclusion, the lower aerobic fitness in people with epilepsy observed may be associated with their sedentary habits. Moreover, our findings reinforce the hypothesis that exhaustive exercise is not a seizure-inducing factor. (C) 2010 Elsevier Inc. All rights reserved.

(Soc Brasil Pediatria, 2013-07-01) Ferrari, Gerson Luis de Moraes [UNIFESP]; Bracco, Mario Maia; Rodrigues Matsudo, Victor K.; Fisberg, Mauro [UNIFESP]; Ctr Estudos Lab Aptidao Fis Sao Caetano Sul CELAF; Universidade Federal de São Paulo (UNIFESP); Hosp Israelita Albert Einstein; CELAFISCS
Objective: To compare the changes in cardiorespiratory fitness in evaluations performed every ten years since 1978/1980, according to the nutritional status and gender of students in the city of Ilhabela, Brazil.Methods: the study is part of the Mixed Longitudinal Project on Growth, Development and Physical Fitness of Ilhabela. the study included 1,291 students of both genders, aged 10 to 11 years old. the study periods were: 1978/1980, 1988/1990, 1998/2000, and 2008/2010. the variables analyzed were: body weight, height, and cardiorespiratory fitness (VO2max - L.min-1 and mL.kg-1.min-1) performed using a submaximal progressive protocol on a cycle ergometer. Individuals were classified as normal weight and overweight according to curves proposed by the World Health Organization of body mass index for age and gender. Analysis of variance (ANOVA) with three factors followed by the Bonferroni method were used to compare the periods.Results: the number of normal weight individuals (61%) was higher than that of overweight. There was a significant decrease in cardiorespiratory fitness in both genders. Among the schoolchildren with normal weight, there was a decrease of 22% in males and 26% in females. in overweight schoolchildren, males showed a decrease of 12.7% and females, of 18%.Conclusion: During a 30-year analysis with reviews every ten years from 1978/1980, there was a significant decrease in cardiorespiratory fitness in schoolchildren of both genders, which cannot be explained by the nutritional status. the decline in cardiorespiratory fitness was greater in individuals with normal weight than in overweight individuals.

Chromosome damage and cytotoxicity in oral mucosa cells after 2 months of exposure to anabolic steroids (decadurabolin and winstrol) in weight lifting
(Elsevier B.V., 2010-12-01) Martins, Renato de Almeida [UNIFESP]; Gomes, Guilherme Augusto da Silva [UNIFESP]; Aguiar, Odair [UNIFESP]; Medalha, Carla Christina [UNIFESP]; Ribeiro, Daniel Araki [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
The aim of the present study was to evaluate DNA damage (micronucleus) and cellular death (pyknosis, karyolysis and karyorrhexis) in exfoliated buccal mucosa cells from anabolic steroid users after 2 months of exposure. Two experimental groups consisting of 15 adult males who practise weight lifting and are anabolic steroid users or 15 adult males who practise weight lifting, but are non-anabolic steroid users, were recruited. in addition, 20 sedentary males, who do not practise any physical activity regularly, were matched by age with experimental groups. No significant statistical differences (p > 0.05) were noticed in individuals who practise physical activity only. On the other hand, an increase of micronucleated cells (MNCs) in anabolic steroid (decadurabulin and Winstrol) users was observed. Regarding cytotoxic parameters, the same observation has occurred, that is, significant statistical differences (p < 0.05) were noticed in the group exposed to anabolic steroids when compared with other controls, as depicted by high frequencies of pyknosis, karyolysis and karyorrhexis. Taken together, our results suggest that genomic instability and cytotoxicity are induced by anabolic steroid administration in oral mucosa cells as assessed by the micronucleus test.

Classificação da variabilidade da frequência cardíaca em praticantes de natação
(Universidade Federal de São Paulo, 2016-09-14) Scorcine, Claudio Ramos Oliveira [UNIFESP]; Colantonio, Emilson [UNIFESP]; http://lattes.cnpq.br/9840076091240222; http://lattes.cnpq.br/9669128404645457; Universidade Federal de São Paulo (UNIFESP)
The cardiovascular system is controlled in part by the autonomic nervous system, through the sympathetic and parasympathetic pathways. These controllers are closely associated with the behavior of heart rate. One way to gauge the performance of most of the routes is through the heart rate variability (HRV) and many studies have shown a relationship between increased activation of the sympathetic system with decreased HRV. This decrease is directly linked to various diseases such as diabetes, hypertension, chronic obstructive pulmonary disease, obesity and others. Another research line deals with the influence of physical activity on the HRV parameters, and has been observed that physical exercise can be positive for the increased rates of HRV. However, in the literature can?t yet predict what the HRV levels that trained individuals must present nor the HRV levels that can be related to any pathology. The objective of this work was to develop a rating scale of HRV indexes in swimming practitioners of both genders. After approval of the Ethics Committee of UNIFESP and signing the Consent and Informed by volunteers, 100 subjects were selected, 70 male and 30 female, separated into three distinct levels of experience (beginner, intermediate and advanced). Statistical analysis was performed using Mann Whitney U test, it was not possible shown significant differences in the rates of HRV between males and females. The data were analyzed in Kubios 2.0 program. After no confirmation of the normality of the data by the Kolmogorov-Smirnov test it was decided to use the Mann-Whitney U test for comparison of HRV index for the gender studied and intensity of training. For to compare the time of practice was used ANOVA with post hoc Bonferroni. Results: There no were observed significant differences in HRV index between male and female, training intensity and time of practice. For the classification table of HRV indexes was used to cluster statistic considering five levels of classification, as follows: Far below the median; below the median; median; above the median and very above the median.

Comportamento sedentário e saúde mental de mulheres: uma revisão sistemática
(Universidade Federal de São Paulo, 2022-02-21) Abreu, Larissa Gabriela [UNIFESP]; Rodrigues, Emília Amélia Pinto Costa [UNIFESP]; http://lattes.cnpq.br/4159801560618581; http://lattes.cnpq.br/6930772901265768; Universidade Federal de São Paulo (UNIFESP)
O presente estudo tem como objetivo de pesquisa revisar na literatura qual a relação do comportamento sedentário com a saúde mental das mulheres com intuito de investigar a importância da atividade física na promoção da saúde e qualidade de vida. O método de pesquisa consistiu em revisão sistematizada e qualitativa das bases de dados Lilacs e Scielo. Os descritores utilizados para seleção dos artigos foram “mulher”, “saúde mental”, “exercício físico”, “atividade física” e “comportamento sedentário”. Os critérios de inclusão foram artigos originais na língua portuguesa que apresentavam mulheres com faixa etária entre 18 e 65 anos, publicados nos últimos 10 anos (2011-2021), com a presença de questionários sobre a prática de atividade física e/ou intervenções com exercício físico. Os critérios de exclusão foram trabalhados do tipo teses, dissertações e monografias e trabalhos contendo maior amostra de homens do que de mulheres. A partir da análise de dados, foram selecionados oito artigos, e para organizar os resultados encontrados, os artigos originais foram separados em duas categorias analíticas. Na primeira categoria são mostrados quatro estudos relacionados com Comportamento Sedentário e Mulher, e na segunda categoria são apresentados quatro estudos relacionados com Comportamento Sedentário e Saúde Mental das Mulheres. Em síntese, na discussão foi constatado que as mulheres são mais suscetíveis para o comportamento sedentário e para o adoecimento mental, e ainda, fatores sociais, culturais, socioeconômicos, demográficos e psicossociais são determinantes para a piora da qualidade de vida e a falta de acesso à prática de atividade física. Por fim, demonstrou-se que existe uma correlação entre o comportamento sedentário e problemas relacionados com a saúde mental de mulheres.
