ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the effects of lipodystrophy and physical exercise on the parameters of bioimpedance spectroscopy (BIS) and bioimpedance vector analysis (BIVA) of people living with HIV (PLWHIV). METHODS: Seventy patients were divided into two groups: PLWHIV with lipodystrophy (PLWHIV-L) and PLWHIV without lipodystrophy (PLWHIV-NL). The phase angle (PhA) and the BIVA were determined from the values of resistance and reactance collected by the BIS. The percentage of fat mass and lean soft tissue (LST) were determined by dual-energy x-ray absorptiometry. For comparisons between the PLWHIV-L and PLWHIV-NL groups, the t test for independent samples or the Mann-Whitney test was used. From the BIVA, the average of the impedance vectors of the two groups was calculated with the 95% confidence ellipse, and the individual vectors of the patients divided by sex were also compared with the tolerance ellipses of 50%, 75%, and 95% of the healthy reference population. The relationships between the variables of interest were determined by the Pearson or Spearman correlation coefficient and the coefficient of determination. Analysis of covariance was used for comparisons between groups, adjusted for possible confounding variables. RESULTS: PLWIV-L showed better hydration conditions (P <0.01), higher LST (P <0.01), and lower percent of fat mass (P <0.01). No differences in PhA were observed between PLWHIV who practiced or did not practice physical exercise. There was a significant difference between the impedance vectors of the groups with and without lipodystrophy (T = 42.4 and P <0.01). Additionally, most of the patients who were positioned beyond the ellipse limits of 50% of tolerance fell into the areas of edema and cachexia. The extracellular to intracellular water ratio explained 81% of the PhA variations. When PhA was adjusted for height2, fat mass/height2 and LST, it was significantly different between groups of the female sex (PhA: P <0.01). CONCLUSION: Lipodystrophy and the practice of physical exercise do not present direct involvement in the PhA values, with sex, body composition, and hydration variables being the main influences on this variable. BIVA was able to show differences in the body composition of the groups even when the PhA values were similar.

ABSTRACT

The present systematic review was compiled to analyze the effectiveness of High-intensity interval training (HIIT) protocols on the body composition of rodents with obesity. Databases were searched until February 2021 for experimental trials in rodents with a minimum duration of four weeks of HIIT and endpoints associated with obesity. The data were analyzed by meta-analysis performed for comparisons of body composition. Sensitivity analysis was performed to investigate the consistency of individual researches. Of all of the 524 studies found, only 14 were included. The analysis showed a significant reduction in body weight ([CI 95%: -8.35; -1.98] P ≤ 0.01), adiposity index ([IC 95%: -1.04; -0.80] P ≤ 0.01), and fat pads ([IC 95%: -0.59; -0.06] P ≤ 0.01). HIIT performed on treadmill or water was effective to reduce body weight (P < 0.05). In conclusion, HIIT attenuated both body weight and adiposity induced either by HFD (high-fat diet) or by GOM (genetic obese model), thereby inducing positive changes in body composition.

ABSTRACT

Abstract Introduction: The growing rate of elderly people in the world can became a public health problem when they exhibit insufficient levels of physical activity, which can increase chronic pain and lead to functional disability. Objective: To analyze the effects of functional training on pain and functional capacity in elderly women. Methods: A non-randomized controlled clinical trial was conducted with 32 elderly women, divided into two groups: functional training (FT: n = 17) and control group (CG: n = 15). Functional capacity was analyzed using the Physical Fitness Test for the Elderly. Pain was assessed by reports of musculoskeletal discomfort symptoms and their characteristics using the Nordic Musculoskeletal Pain Questionnaire and pain visual analog scale (VAS). The functional training program was applied for 12 weeks at a frequency of three times a week. Results: Significant effects after the intervention in the FT group were observed, with pain reduction, increased flexibility and resistance for lower limbs, and cardiorespiratory capacity (p < 0.05). Conclusion: The functional training program in elderly women was effective in improving the variables of lower limb flexibility, pain perception, lower limb strength resistance and cardiorespiratory capacity.


Resumo Introdução: O crescimento da taxa de idosos no mundo pode tornar-se um problema de saúde pública quando estes exibem níveis insuficientes de atividade física, que têm o potencial de aumentar dores crônicas e causar incapacidade funcional. Objetivo: Analisar os efeitos do treinamento funcional na dor e capacidade funcional de mulheres idosas. Métodos: Desenvolveu-se um ensaio clínico controlado não randomizado com 32 idosas, divididas em dois grupos: treino funcional (TF: n = 17) e grupo controle (GC: n = 15). Como indicador da capacidade funcional foi utilizado o Teste de Aptidão Física para Idosos. A dor foi avaliada pelos relatos de sintomas de desconforto musculoesquelético e suas características por meio do Questionário Nórdico de Sintomas Osteomusculares de Dor e Escala visual Analógica de Dor (EVA). O programa de treinamento funcional foi aplicado por 12 semanas em uma frequên-cia de três vezes semanais. Resultados: Verificaram-se efeitos significativos após a intervenção no grupo TF, com redução da dor e aumento da flexibilidade e resistência para membros inferiores e capacidade cardiorrespiratória (p < 0,05). Conclusão: O programa de treinamento funcional em idosas foi efetivo para a melhoria das variáveis de flexibilidade de membros inferiores, percepção de dor, resistência de força de membros inferiores e capacidade cardiorrespiratória.

ABSTRACT

INTRODUÇÃO: O estilo de vida ativo pode contribuir de forma expressiva em pessoas vivendo com HIV/aids auxiliando na melhoria das capacidades físicas e combate aos efeitos adversos da medicação. OBJETIVO: Analisar a associação entre atividade física e fatores sociodemográficos e de saúde em pessoas vivendo com HIV/aids do município de Ourinhos-SP. MÉTODOS: Foram entrevistados pacientes em tratamento no Serviço de Atendimento Especializado em Doenças Infecciosas (SAEDI). A atividade física habitual e seus domínios foram avaliados mediante o questionário de Baecke, além disso, os prontuários dos pacientes foram acessados para coleta de dados adicionais de saúde. RESULTADOS: Como principais resultados, observou-se baixos níveis de atividade física de lazer na população investigada (21,0%). Modelos de regressão de Poisson ajustados por fatores de confundimento identificaram associação entre atividade física ocupacional e maior classe social (RP: 3,32; IC95%: 1,34-8,25); atividades físicas de lazer e locomoção e maior pressão arterial diastólica (PAD) (RP: 3,17; IC95%: 1,43-7,07); atividade física habitual e tempo de diagnóstico superior a 150 meses (RP: 3,18; IC95%: 1,16-8,72) e maior prevalência de exercícios físicos no lazer associou-se a maior classe social (RP: 2,86; IC95%: 1,11-7,36). CONCLUSÃO: Pessoas vivendo com HIV/aids em tratamento na região de Ourinhos apresentam baixos níveis de atividade física. Além disso, classe social, tempo de diagnóstico e PAD apresentaram relações com atividade física.


INTRODUCTION: An active lifestyle may contribute significantly to people living with HIV/aids by improving physical abilities and reducing the adverse effects of medications. OBJECTIVE: To analyze the association between physical activity and sociodemographic and health factors in people living with HIV/aids in the municipality of Ourinhos-SP. METHODS: Patients undergoing treatment were interviewed at the Specialized Infectious Diseases Care Service. Habitual physical activity and its domains were evaluated using the Baecke questionnaire and patients' charts were consulted for additional health data. RESULTS: The proportion of individuals undertaking leisure physical activity in our sample was low (21%). Poisson regression models, adjusted for confounding factors, identified associations between occupational physical activity and higher social class (PR: 3.32; 95% CI: 1.34-8.25); between leisure physical activity and locomotion and higher diastolic blood pressure (DBP) (PR: 3.17; 95% CI: 1.43-7.07); and between habitual physical activity and duration of diagnosis >150 months (PR: 3.18; 95% CI: 1.16-8.72) and higher prevalence of leisure physical activities was associated with higher social class (PR: 2.86, 95% CI: 1.11-7.36). CONCLUSION: People living with HIV/aids and undergoing treatment in the Ourinhos region have low levels of physical activity. Furthermore, social class, duration of diagnosis and DBP were found to be associated with physical activity.

ABSTRACT

O objetivo do estudo foi identificar barreiras percebidas à prática de atividade física antes e após participarem de um programa de exercícios físicos (EF), bem como aspectos ligados à adesão e a aderência à este programa, em pessoas vivendo com HIV/aids, especificamente: motivos referidos para faltas as sessões, número de desistências ao longo do programa, continuidade de prática após seis meses ao término do programa e motivos para eventuais não continuidades. Dezenove sujeitos participaram de 14 semanas de um programa de EF. Foram coletadas informações sobre barreiras percebidas para a prática de atividade física, os motivos de faltas ou desistência e a continuidade após seis meses ao término do programa. Para análise dos dados utilizou-se estatística descritiva, o teste de McNemar para verificar as diferenças nas frequências de cada barreira, e de Wilcoxon para comparar o número médio de barreiras no momento pré e pós programa. A média de assiduidade às sessões foi de 58,5% e os principais motivos relatados para as faltas foram "problemas de saúde" e "compromissos pessoais". Cerca de 40% das pessoas que iniciaram o programa não chegaram até o final do mesmo. A maior parte das desistências aconteceu entre a 11ª e a 20ª sessão. Não houve diferenças significativas nas barreiras referidas pré e pós programa, nem no número médio de barreiras. Somente 21% dos sujeitos referiram estar praticando EF após seis meses. Programas de EF devem considerar estes acha-dos e buscar elaborar ações mais sustentáveis e de maior impacto a longo prazo na saúde dos sujeitos.


The objective of the study was to evaluate, in people living with HIV/AIDS, perceived barriers to physical activity practice before and after participating in a physical exercise (PE) program, as well as aspects related to adherence to the program, specifically: reasons given for absence from sessions, number of with drawals during the program, continuity of practice six months after the end of the program, and reasons for eventual non-continuity. Nineteen subjects participated in a 14-week PE program. Information was collected on perceived barriers to physical activity, reasons for absences or withdrawal, and continuity six months after the end of the program. Descriptive statistics were used for analysis of the data, the Mc Nemar test to verify the differences in the frequencies of each barrier, and the Wilcoxon test to compare the mean number of barri-ers pre- and post-program. The average at tendance at the sessions was 58.5% and the main reasons reported for absences were "health problems" and "personal commitments". About 40% of the people who started the program did not continue to the end of the program. The majority of dropouts occurred between the 11th and 20th sessions. There were no significant differences in the pre- and post- barriers reported, or in the mean number of barriers. Only 21% of the subjects reported racticing PE six months after the program. PE programs should consider these findings and seek to develop more sustainable actions with a greater long-term impact on the health of the subjects.

ABSTRACT

PURPOSE: The aim of this study was to conduct a randomized clinical trial to assess the effects of 16 weeks of combined training on body composition, lipid profile, adiponectin, C-reactive protein (CRP), and leptin levels in people living with HIV/AIDS (PLWHA). METHODS: Fifty-eight HIV-infected individuals were randomized into a training group (T) or a control group (C). Combined training consisted of aerobic and resistance exercises performed at the same training session, applied at a frequency of three times a week for a total of 16 weeks. Waist circumference, body mass, body fat percentage (%fat), fat mass, lipid profile, adiponectin, CRP, and leptin levels were measured pre- and post-training in both groups. RESULTS: Sixteen weeks of combined training decreased (P < 0.05) body fat in different body segments in PLWHA. Lipodystrophic PLWHA experienced greater reduction in body fat in the android region than non-lipodystrophic PLWHA after combined training. Lipid profile and circulating levels of adiponectin, leptin, and CRP remained unchanged. CONCLUSIONS: Sixteen weeks of combined training was effective to reduce body fat in different body segments, without altering plasma lipid and cytokine levels.

ABSTRACT

The present study aimed to determine the effects of physical training performed by parents on mice offspring adiposity. Male and female parents underwent an aerobic training protocol for 7 weeks. The trained and sedentary parents were allowed to mate and the resultant offspring divided in: S (Offspring from Sedentary Parents), T (Offspring from Trained Parents), ST (Offspring from Sedentary Father and Trained Mother) and TS (Offspring from Trained Father and Sedentary Mother). After weaning, offspring was euthanized, blood collected and samples of mesenteric and inguinal fat pads used to isolate adipocytes for morphologic and histological analyses. Lee index, mesenteric fat pad, sum of visceral fat and total fat weight of female T was reduced in comparison to the other groups (p < 0.05). Periepididymal and sum of visceral fat in male T group was also reduced when compared to the other groups (p < 0.05). The diameter of mesenteric and inguinal adipocytes of T group was smaller compared to all groups comparisons for both sexes (p < 0.05). In summary, exercise training performed by parents reduced visceral offspring adiposity, the diameter of subcutaneous adipocytes and improved metabolic parameters associated to metabolic syndrome.

ABSTRACT

PURPOSE: Verify the effects of concurrent training on cytokines in people living with HIV under antiretroviral therapy (ART) treatment. METHODS: This was a blinded, parallel-group, clinical trial, where 49 participants, divided in two groups, either control group or concurrent training group, took part in the intervention. The control group performed recreational activities and concurrent training group participated of 16-week, 3 times per week of heart rate guided-aerobic plus resistance training for major muscular groups. Cytokines (interleukins 4, 5, 6, 8, 10, tumor necrosis factor-α, interferon-γ, and granulocyte-macrophage colony-stimulating factor) were measured before and after 16-week experimental period using flow cytometry. RESULTS: From 49 participants who took part in the intervention, 28 completed the program and had data analyzed. There was a significant interaction for IL-8, which increased for control group: 7.1±5.1 vs. 8.1±6.0 and a decrease for concurrent training: 8.0±4.4 vs. 5.4±2.3. In addition, magnitude-based inference showed a likely beneficial effect for the training group when compared to the control group for IL-8, IL-5, and IL-10. The difference perceptual: mean and [CI 90%] between delta of difference within groups was -43.1 [-64.0 to -10.0] and -6.6 [-14.7 to 2.3], respectively. CONCLUSION: Short-term exercise is able to decrease the levels of IL-5, IL-8, and IL-10 in HIV-infected people undergoing ART.

ABSTRACT

RESUMO O treinamento físico é uma estratégia importante para a saúde de pessoas que vivem com HIV/AIDS; contudo, suas respostas a curto prazo ainda não foram amplamente estudadas, o que limita o entendimento dos efeitos e da segurança da prescrição do treinamento para essa população. Portanto, objetivou-se revisar sistematicamente as respostas agudas decorrentes do exercício físico em pessoas com HIV sobre variáveis fisiológicas e imunológicas. Para isso, foi realizada uma revisão sistemática a partir de trabalhos indexados nas seguintes bases de dados: Medline, Lilacs, Scielo, Web of Science e Science Direct. Os descritores utilizados foram: acquired immunodeficiency syndrome, HIV, AIDS, seropositive, acute session, short, physical activity, exercise, training. As buscas foram realizadas em fevereiro de 2015 e atualizadas em dezembro de 2015 e foram conduzidas sem restrição de datas de publicação ou idioma específico. Foram incluídos para esta revisão artigos que avaliaram as respostas agudas decorrentes de algum modelo de prescrição de treinamento físico envolvendo exercícios aeróbicos, com pesos ou combinados (exercícios aeróbicos e com pesos) relacionados com variáveis fisiológicas e imunológicas em pessoas infectadas pelo HIV. Foram encontrados 2.422 títulos, dos quais, após exclusão das duplicatas e a aplicação dos critérios de elegibilidade, foram selecionados sete artigos para síntese qualitativa. De acordo com os resultados reportados pelos estudos há evidências de que, imediatamente após a realização do exercício físico, ocorre um aumento do número de células circulantes, incluindo leucócitos totais, neutrófilos, monócitos e linfócitos T CD8+ em pessoas infectadas pelo HIV. Além disso, também se observaram alterações significantes nas concentrações de lactato, triglicerídeos, epinefrina e norepinefrina imediatamente após a realização do treinamento aeróbico, independentemente do uso de TARV e/ou de hiperlactatemia. No entanto, não há evidências suficientes para afirmar que o treinamento físico seja totalmente seguro e eficaz para esta população.


ABSTRACT Physical training is an important strategy for the health of people living with HIV/aids; however, its short-term responses have not yet been extensively studied, which limits the understanding of the effects and safety training prescription for this population. Therefore, we aimed to systematically review the acute responses resulting from physical exercise in people with HIV on physiological and immunological variables. For this, a systematic review was carried out from works indexed in the following databases: Medline, Lilacs, Scielo, Web of Science and Science Direct. The keywords used were acquired immunodeficiency syndrome, HIV, AIDS, seropositive, acute session, short, physical activity, exercise, training. The searches were conducted in February 2015 and updated in December 2015 and were conducted without restriction of publication dates or specific language. We included for this review articles that evaluated the acute responses derived from some model of prescription of physical training involving aerobic, weight or combined exercises (aerobic and weight exercises) related to physiological and immunological variables in HIV infected individuals. We found 2,422 titles of which, after exclusion of the duplicates and the application of the eligibility criteria, seven articles were selected for qualitative synthesis. According to the results reported by the studies, there is evidence that immediately after physical exercise an increase in the number of circulating cells occurs, including total leukocytes, neutrophils, monocytes and T CD8+ lymphocytes in HIV-infected people. Furthermore, significant changes in the concentrations of lactate, triglycerides, epinephrine and norepinephrine were also observed immediately after aerobic training regardless the use of HAART and/or hyperlactatemia. However, there is insufficient evidence to state that physical training is totally safe and effective for this population.

ABSTRACT

O objetivo do presente estudo foi analisar a concordância de três instrumentos de medidas de amplitude da coluna cervical. A amostra foi constituída por quarenta e uma mulheres universitárias (20,8 ± 2,2 anos, 1,78 ± 0,07 m, 57,1 ±11,3 kg) as quais foram avaliadas pelos diferentes instrumentos de medida (inclinômetro marca Lafayette, flexímetro marca Sanny e flexímetro marca Code) nos movimentos de flexão e extensão da coluna cervical. Todas as medidas foram realizadas no período da manhã, por um único avaliador experiente e familiarizado com os procedimentos de coleta e a ordem de medida foi idêntica para todas as participantes. Não houve diferenças significantes na extensão da coluna cervical entre os três instrumentos, com valores de concordância próximos de zero (-0,04 < d < 0,31), todavia, com coeficientes de determinação baixos (0,64 < R2 < 0,71). O movimento de flexão da coluna cervical, embora com valores de concordância também próximos de zero (-0,2 < d < -1,6), apresentou diferenças significantes entre os instrumentos (Inclinômetro vs Flexímetros Code e Sanny), com coeficientes de determinação mais baixos (0,01 < R2 < 0,41). Concluímos que os instrumentos apresentam diferença nos escores produzidos, especificamente, em relação ao movimento de flexão da coluna cervical de mulheres universitárias. Em casos de aplicação clínica, qualquer um dos instrumentos pode ser empregado para avaliação. Entretanto, para a flexão da coluna cervical, deve haver certa cautela quanto à escolha do instrumento, tendo em vista a diferença existente entre os escores produzidos.


The purpose of the present study was to compare and analyze the agreement of three equipments of cervical spine range of motion assessment. The sample was composed by forty-one college women (20.8 ± 2.2 years, 1.78 ± 0.07 m, 57.1 ±11.3 kg), who were evaluated by the different equipments (Lafayette inclinometer, Sanny and Code fleximeters) in flexion and extension of cervical spine. All the measures were performed in the morning period, by an experienced technician and conversant with the data procedures, and the measurement order was identical for all the participants. There were no significant differences among scores produced by the three instruments for extension (median=63 degrees; p = 0.95), with concordance scores around zero (-0,04 < d < 0,31), however, with low determination and explanation coefficients (0,64 < R2 < 0,71). For the flexion of cervical spine, although with concordance scores around zero (-0,2 < d < -1,6), there were significant differences between the equipments (Inclinometer vs Fleximeters (Code and Sanny). We concluded that the equipments present differences over the scores, specifically on the flexion of cervical spine in college women.

ABSTRACT

O objetivo deste estudo é comparar e analisar a concordância de três instrumentos de medidas (inclinômetro marca Lafayette, flexímetro marca Sanny e flexímetro marca Code) nos movimentos de flexão e extensão da coluna cervical. A amostra foi composta por 41 homens universitários (20,8 ± 2,2 anos, 1,78 ± 0,07 m, 57,1 ±11,3 kg). Para a análise dos dados, utilizaram-se ANOVA one-way, concordância de Bland e Atlman, análise de regressão múltipla, correlação de Spearman, adotando-se uma significância de 5%. Não houve diferenças significantes entre os valores de amplitude de movimento avaliados pelos diferentes instrumentos para a flexão (mediana=63 graus; P=0,95) e extensão da coluna cervical (mediana=73 graus; P=0,90). Para todos os instrumentos, foram observados valores de concordância, entre as análises, próximos de zero (-0,34< < 0,26). Conclui-se que os valores de amplitude de movimento não diferem entre os instrumentos, possibilitando a comparação de medidas realizadas por eles, especificamente para universitários do sexo masculino.


The purpose of the present study was to compare and analyze the concordance of three instruments (Inclinometer Lafayette, fleximeter Sanny, and fleximeter Code) in flexion and extension of cervical spine. The sample was composed by forty-one college men (20.8 ± 2.2 years, 1.78 ± 0.07 m, 57.1 ±11.3 kg). For statistical analyses ANOVA one-way, Bland and Atlman procedures, multiple regression analysis, and Spearman correlation coefficient were employed, with P< 0.05. According to the results, there were no significant differences among scores produced by the three instruments for flexion (median=63 degrees; P=0.95) and extension of cervical spine (median=73degrees; P=0.90), and concordance scores, between the analyzes, near zero (-0.34< < 0.26). The results of this study indicate that the fleximeter Code, fleximeter Sanny, and inclinometer Lafayette measurement values are consistent, which allows comparisons between themselves and using similar cutoffs, specifically for healthy male college students, in flexion and extension of cervical spine, specifically for college men.

ABSTRACT

O propósito deste estudo foi analisar a prevalência de barreiras pessoais para a prática de atividade física percebidas em portadores de AIDS. Trinta e cinco sujeitos de ambos os gêneros participaram voluntariamente deste estudo. Três questionários foram aplicados na seguinte sequência: a) barreiras pessoais percebidas para prática de atividade física; b) nível de atividade física habitual e c) socioeconômico. A prevalência de prática de atividade física adequada nas horas de lazer (≥ 150 min/sem) foi de 23,5%. As principais barreiras pessoais percebidas para prática de atividade física identificadas foram: (1) preguiça ou cansaço (48,6%); (2) falta de companhia (45,7%); (3) possuir lesão ou doença (37,2%) e (4) falta de dinheiro e medo de se machucar (34,3%, para ambas). Os resultados sugerem que a principal barreira pessoal percebida para prática de atividade física relatada pelos participantes guarda relação com os efeitos colaterais da medicação antirretroviral utilizada para o controle da AIDS.


The purpose of this study was to analyze the prevalence of personal barriers to physical activity perceived by patients with AIDS. Thirty-five subjects, both genders, voluntarily participated in this study. Three questionnaires were applied in the following sequence: a) perceived personal barriers to physical activity, b) the level of habitual physical activity, and c) Socioeconomic. The prevalence of adequate physical activity during leisure time (≥ 150 min / week) was 23.5%. The main personal barriers perceived to physical activity were: (1) laziness or fatigue (48.6%), (2) lack of company (45.7%), (3) injury or illness (37.2 %), (4) lack of money and fear of injury (34.3% for both). The results suggest that the main barrier perceived by participants to personal physical activity is related to the side effects of antiretroviral drugs used to control AIDS.

ABSTRACT

A análise fotogramétrica pode ser feita por meio de diferentes programas computacionais. Assim, o objetivo do presente estudo foi avaliar a confiabilidade e usabilidade de três diferentes programas em uma análise fotogramétrica durante a flexão do quadril e discutir aspectos qualitativos e quantitativos de cada um deles. Participaram do estudo 26 voluntários do gênero masculino, com idade entre 19 e 30 anos (x=25,4 anos, DP=2,5) que realizaram o teste do sentar e alcançar por meio do banco de Wells adaptado. Marcadores cutâneos foram posicionados nos processos ósseos: trocânter maior do fêmur e espinha ilíaca anterossuperior. A aquisição da imagem foi realizada no limite máximo da execução do teste. Todos os programas apresentaram uma alta confiabilidade entre as medidas, além disso, foram apresentadas vantagens e desvantagens específicas na adoção de cada um deles. O programa SAPO foi considerado com maiores vantagens para utilização na prática profissional, no entanto, para realização de análises em pesquisas científicas todos os programas apresentam pontos que devem ser considerados antes da sua adoção.


The photogrammetric analysis can be done by using different softwares. Thus, the purpose of this study was to assess the reliability and the usability of three different softwares during the hip flexion photogrammetric analysis and to discuss the qualitative and quantitative aspects of each one. Twenty-six volunteers participated in this study with age between 19 and 30 years old (x=25.4 years, SD=2.5) who underwent the sit-to-reach test through adapted Wells´ bench. Reflective skin markers were positioned in the anterior superior iliac spine and greater trochanter. The image acquisition was collected in the maximum limit of test execution. All softwares showed a high reliability between measures, besides it was presented specifics advantages and disadvantages during adoption one of them. SAPO´s software was considered with major points for professional practice, although taking the analysis for scientific research all softwares demonstrated characteristics that must be taken into consideration before adopting them.

ABSTRACT

OBJETIVO: Verificar a prevalência e os fatores associados à ocorrência da pressão arterial elevada em adolescentes de alto nível econômico. MÉTODOS: Foram investigados 233 alunos (113 meninos e 120 meninas) matriculados entre a quinta e a oitava série do ensino fundamental de escolas privadas de Londrina, Paraná. Foram coletadas informações sobre classificação econômica e os hábitos ligados ao consumo alimentar, por meio de questionários. A massa corporal foi avaliada por balança digital da marca Plenna e a altura por estadiômetro de madeira com precisão de 0,1cm. A pressão arterial foi aferida por aparelho oscilométrico automático. Para a análise estatística, utilizou-se o teste do qui-quadrado ou o teste t para avaliar a associação entre a pressão arterial e os fatores de risco. A regressão de Poisson indicou a magnitude dessas associações. RESULTADOS: A prevalência da pressão arterial elevada foi de 12,4 por cento entre os estudantes. Foram verificadas associações entre a pressão arterial elevada e as variáveis: sexo e estado nutricional. Posteriormente, no modelo ajustado, a regressão de Poisson somente indicou significância entre a associação da pressão arterial elevada e o estado nutricional. CONCLUSÕES: Observou-se significativa prevalência de pressão arterial elevada em adolescentes de alto nível econômico e os valores elevados de pressão arterial se associaram ao excesso de peso corporal.


OBJECTIVE: To verify the association between elevated blood pressure and related risks factors on adolescents of high economic level. METHODS: The sample included 233 schoolchildren (113 boys and 120 girls) on the fifth to the eighth grades of private elementary schools from Londrina, Paraná, Brazil. The subjects' economic level and food intake were evaluated by a questionnaire. The body mass was assessed with a Plenna digital scale; the height was measured with a wooden stadiometer (precision: 0.1cm); and the blood pressure, with an oscillometric device. Association between elevated blood pressure and different risk factors were evaluated by the t-test, chi-square test and by Poisson's regression with robust variance. RESULTS: Elevated blood pressure was present in 12.4 percent of the students and it was associated with gender and nutritional status. Poisson's regression adjusted model suggested that only nutritional status was independently associated with elevated blood pressure. CONCLUSIONS: A high rate of elevated blood pressure was found in adolescents from high economic level, and overweight was associated with this condition.

ABSTRACT

This study analyzed the accuracy/agreement of the Omron MX3 monitor on 165 adolescents. Blood pressure was measured by the automatic monitor connected in Y with the mercury column (three consecutive and simultaneous measures). The independent measures were analyzed, and the mean differences between systolic and diastolic measures for both methods were calculated and compared with British Hypertension Society (BHS) and Association for the Advancement of Medical Instrumentation (AAMI) criteria. The automatic monitor received the highest degree of BHS recommendations for systolic and diastolic blood pressures according to the BHS. The median (25th and 75th) difference between the observer and the monitor measurements was -2 (-6 and 1) mmHg for systolic and 0 (-3 and 1) mmHg for diastolic pressures. The monitor also satisfies the AAMI standard for the studied population. In conclusion, the Omron MX3 Plus monitor can be considered reliable and valid for clinical practice and is in accordance with BHS and AAMI criteria.

ABSTRACT

O propósito do presente estudo foi analisar o comportamento da força muscular e da área muscular de braço (AMBr) durante 24 semanas de treinamento com pesos (TP) e estabelecer possíveis associações entre essas variáveis. A amostra foi composta por 18 homens, com idade de 18-30 anos. Para o cálculo da AMBr, foram utilizadas as medidas de circunferência de braço relaxado e espessura de dobra cutânea de tríceps. Para a avaliação da força muscular foi utilizado o teste de uma repetição máxima (1-RM) no exercício rosca direta de bíceps. O protocolo de TP teve uma duração de 24 semanas sendo dividido em três fases (F1, F2 e F3) de oito semanas cada. Vale ressaltar que todas as medidas foram realizadas antes, durante e após o término do período de TP. ANOVA para medidas repetidas, seguida do teste post hoc de Tukey (P < 0,05), foi utilizada para as comparações entre os indicadores de força e hipertrofia muscular. O coeficiente de correlação de Pearson foi empregado para verificar as possíveis associações entre a força muscular e a AMBr. A força muscular e a AMBr aumentaram de forma contínua durante todo o período com exceção do período inicial (F1). Sendo assim, concluise que durante a fase inicial de treinamento o fator neural parece ter sido o grande responsável pelo aumento da força muscular. Após esse período, o processo hipertrófico parece constituir-se gradativamente como fator essencial para os aumentos da força muscular.


The purpose of this study was to analyze the behavior of muscle strength and arm muscle area (AMA) over 24 weeks of weight training (WT) as well as to establish possible associations between these variables. The sample was composed of 18 men aged between 18 and 30 years. Measurements of relaxed arm circumference and triceps skinfold measurement were used for the calculation. Muscle strength was assessed using the one-repetition maximum test (1-RM) on the arm curl exercise. The WT protocol lasted 24 weeks, divided into 3 stages (F1, F2, and F3) of 8 weeks each. It is important to emphasize that every measurement was made before, during and after the end of the WT period. Analysis of variance (ANOVA) for repeated measures followed by the Tukey post hoc (P < 0.05) was used to the compare the indicators of muscle strength and muscle hypertrophy. Pearson’s correlation coefficient was used to verify possible association between muscle strength and AMA. Muscle strength and AMA increased continuously throughout the whole period except for the initial period (F1). Therefore, it is concluded that the initial phase of training, neuromuscular adaptation, seems to have been the turning point for increase in muscle strength. After that, the hypertrophy process appears to gradually become the essential factor for increase in muscle strength.

ABSTRACT

O objetivo deste estudo foi analisar a composição corporal de crianças de sete a 10 anos de idade, de alto nível socioeconômico. Para tanto, 511 crianças (274 meninos e 237 meninas) foram submetidas a medidas antropométricas de massa corporal, estatura e espessuras de dobras cutâneas tricipital (TR) e subescapular (SE). Com base nessas informações, foram determinados: gordura corporal relativa ( por cento Gordura), massa corporal magra (MCM), distribuição da gordura corporal (DGC) e o somatório da espessura das dobras cutâneas TR e SE (ΣEDC). Anova two-way foi utilizada para as comparações entre os sexos e os diferentes grupos etários, seguida pelo teste post hoc de Scheffé quando P < 0,05. Para a classificação das crianças, de acordo com as categorias de adiposidade corporal, foi utilizada distribuição de freqüência. O teste de comparação entre proporções foi adotado para verificar as diferenças entre os sexos, em cada categoria (P < 0,05). Diferenças significantes entre os sexos (P < 0,05) foram verificadas na dobra TR (meninas > meninos) e na MCM (meninos > meninas). Efeito significante da idade foi identificado em todas as variáveis analisadas, exceto na DGC, com os valores mais elevados sendo encontrados no grupo etário de 10 anos. Um percentual elevado, tanto de meninos quanto de meninas, apresentou índice de adiposidade alto, com superioridade para os meninos (28 por cento vs. 14 por cento, P < 0,01). Por outro lado, um contingente maior de meninas apresentou concentrações de gordura corporal relativa abaixo dos pontos de corte desejáveis (15 por cento vs. 3 por cento, P < 0,01). Os valores de adiposidade corporal encontrados no presente estudo sugerem que um percentual elevado de crianças, de ambos os sexos, já apresenta importantes fatores de risco à saúde, em idades precoces.


The objective of this study was to analyze the body composition of seven to 10 year-old children of high socioeconomic status. Therefore, 511 children (274 boys and 237 girls) were submitted to body mass, height and triceps (TR) and subscapular (SE) skinfolds thickness anthropometric measurement. Based on this information, the following topics were determined: relative body fat ( percent Fat), lean body mass (LBM), body fat distribution (BFD) and sum of the thickness of the TR and SE skinfolds (£TSF). Two-way ANOVA was used for comparisons between gender and the different age groups, followed by the Scheffé post hoc test when P < 0.05. For the children classification according to the categories of body adiposity, frequency distribution was used. A test of comparison between ratios was adopted to verify the differences between gender in each category (P < 0.05). Significant differences between gender (P < 0.05) were verified in TR skinfold (girls > boys) and in LBM (boys > girls). Significant age effect was identified in all analyzed variables, except for DBF, with the highest values having been found in the 10 year-old group. A high percentage both for boys and girls presented high adiposity index, with superiority for boys (28 percent vs. 14 percent, P < 0.01). On the other hand, a larger number of girls presented relative body fat concentrations below the desirable cutting points (15 percent vs. 3 percent, P < 0.01). The values of body adiposity found in the present study suggest that a high percentage of children from both gender already present important health risk factors at early ages.
