ABSTRACT BACKGROUND: Screening for probable and confirmed sarcopenia using sociodemographic and anthropometric indicators can be a practical, cheap, and effective strategy to identify and treat older people susceptible to this condition. OBJECTIVES: To identify cutoff points for sociodemographic and anthropometric variables in screening probable and confirmed sarcopenia in community-dwelling older adults. DESIGN AND SETTING: This was a cross-sectional study of community-dwelling older adults in Araranguá, Santa Catarina, Brazil. METHODS: Sociodemographic (age, education) and anthropometric (weight, height, body mass index [BMI], waist circumference [WC], and dominant calf circumference [DCC]) factors were considered as predictors. The outcomes were probable sarcopenia (reduction in muscle strength assessed by time ≥ 15 s in the five-time sit-to-stand test) and confirmed sarcopenia (reduction in strength and muscle mass). Receiver operating characteristic curve analysis was used to analyze the ability to track sociodemographic and anthropometric variables for sarcopenia. RESULTS: In 308 older adults, WC > 91 cm in women and age > 69 years in men were useful in screening for probable sarcopenia. The variables age, weight, BMI, WC, and DCC can be used to screen for sarcopenia in older women and men. CONCLUSION: Sociodemographic and anthropometric variables are simple and accessible tools for sarcopenia screening in older adults.

ABSTRACT Given the gap in the literature regarding the peak of oxygen consumption (VO2peak) for adolescents of both sexes, this study aimed to propose an equation to predict the VO2peak in healthy adolescents using the Modified Shuttle Test (MST). This is a cross-sectional study with 84 healthy adolescents between 12 and 18 years old, female and male. The MST is an external paced test, in which the speed increases at each minute. Two MST were performed with at least 30 minutes of rest between them. The test with the longest walked distance was considered for analysis. VO2 was directly monitored by an open circuit spirometry. Mean age was 14.67±1.82 and the walked distance was 864.86±263.48m. Variables included in the prediction equation were walked distance and sex, explaining the VO2peak variability of 53% during MST performance. The prediction equation for VO2peak with the MST was: predicted VO2peak=18.274+(0.18×Distance Walked, meters)+(7.733×Sex); R2=0.53 and p<0.0001 (sex: 0 for girls, 1 for boys). This MST equation, proposed to predict VO2peak in healthy adolescents of both sexes, can be used as a reference to assess exercise capacity in healthy adolescents and to investigate cardiopulmonary function in adolescents with reduced functional capacity.

RESUMEN Dada una laguna en la literatura con respecto a la ecuación para predecir el consumo máximo de oxígeno (VO2) en adolescentes de ambos sexos, el objetivo de este estudio es proponer una ecuación para predecir el VO2máximo en adolescentes sanos usando el shuttle test modificado (MST). Se trata de un estudio transversal, realizado con 84 adolescentes sanos con edades entre 12 y 18 años, de ambos sexos. El MST es una prueba de campo dictada por una señal sonora que indica el aumento de velocidad cada minuto. Se realizaron dos MST con al menos 30 minutos de descanso entre ellos. Para el análisis se consideró la prueba con mayor distancia recorrida. El monitoreo del VO2 fue realizado directamente por espirometría de circuito abierto. La edad media fue de 14,67±1,82 años; y la distancia recorrida, de 864,86±263,48m. Las variables incluidas en la ecuación de predicción fueron la distancia recorrida y el sexo, que explicaron el 53% de la variabilidad del VO2máximo durante la realización del MST. La ecuación de referencia para el VO2máximo predicho con el MST fue VO2máximo previsto=18,274+(0,18×Distancia recorrida, en metros)+(7,733×Sexo); R2=0,53 y p<0,0001 (sexo: 0 para chicas, 1 para chicos). La ecuación MST propuesta para predecir el VO2máximo en adolescentes sanos de ambos sexos puede utilizarse como una referencia para evaluar la capacidad de ejercicio en adolescentes sanos y para investigar la función cardiopulmonar en adolescentes con capacidad funcional reducida.

RESUMO Dada a lacuna na literatura quanto à equação de predição do pico de consumo de oxigênio (VO2) para adolescentes de ambos os sexos, o objetivo deste estudo é propor uma equação para predizer o VO2pico em adolescentes saudáveis utilizando o shuttle test modificado (MST). Trata-se de um estudo transversal realizado com 84 adolescentes saudáveis entre 12 e 18 anos, do sexo feminino e masculino. O MST é um teste de campo ditado por um sinal sonoro que indica o aumento da velocidade a cada minuto. Dois MSTs foram realizados com pelo menos 30 minutos de descanso entre eles. O teste com a maior distância percorrida foi o considerado para análise. O VO2 foi monitorado diretamente por uma espirometria de circuito aberto. A média de idade foi de 14,67±1,82 anos, e a de distância percorrida foi de 864,86±263,48m. As variáveis incluídas na equação de predição foram distância percorrida e sexo, que explicaram 53% da variabilidade do VO2pico durante a realização do MST. A equação de referência para o VO2pico previsto com o MST foi VO2pico predito=18,274+(0,18×Distância percorrida, em metros)+(7,733×Sexo); R2=0,53 e p<0,0001 (sexo: 0 para meninas, 1 para meninos). A equação do MST proposta para predizer o VO2pico em adolescentes saudáveis de ambos os sexos pode ser usada como referência para avaliar a capacidade de exercício em adolescentes saudáveis e investigar a função cardiopulmonar em adolescentes com capacidade funcional reduzida.

ABSTRACT Symptoms in post-COVID-19 patients who require hospitalization can persist for months, significantly affecting their health-related quality of life (HRQoL). Thus, the present study aimed to discuss the main findings regarding HRQoL in post-COVID-19 patients who required hospitalization. An electronic search was performed in the MEDLINE, EMBASE, CINAHL, Web of Science, LILACS, and Scopus databases, without date and language restrictions, until July 2021. Twenty-four articles were included in the analysis. It seems that HRQoL partially improved soon after hospital discharge, although the negative impact on HRQoL may persist for months. The physical and mental aspects are affected because patients report pain, discomfort, anxiety, and depression. The HRQoL of COVID-19 infected patients was worse than that of uninfected patients. Additionally, HRQoL seemed worse in patients admitted to the intensive care unit than in those who remained in the ward. Improvements in HRQoL after hospital discharge are independent of imaging improvement, and there seems to be no association between HRQoL after hospital discharge and disease severity on hospital admission. Many factors have been identified as determinants of HRQoL, with women and advanced age being the most related to worse HRQOL, followed by the duration of invasive mechanical ventilation and the need for intensive care. Other factors included the presence and number of comorbidities, lower forced vital capacity, high body mass index, smoking history, undergraduate education, and unemployment. In conclusion, these findings may aid in clinical management and should be considered in the aftercare of patients.

ABSTRACT Patients with Chagas disease have reduced health-related quality of life (HRQoL). Hence, we aimed to identify the factors that mostly affected their HRQoL. This was a systematic review of qualitative studies. The Latin American and Caribbean Health Sciences Literature, Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Web of Science, and SciVerse Scopus databases were searched for relevant studies without language or date restrictions. The search and data analysis were performed by independent reviewers; all qualitative studies that reported the factors that had an impact on the HRQoL of patients with Chagas disease were included. The risk of bias was assessed using the Critical Appraisal Skills Program Qualitative Study Checklist; confidence in the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative approach. Five studies were included in this review: four in Brazil and one in California, United States, with immigrants from Central and South America. The sample consisted of 207 patients with chronic Chagas disease. Stigma, physical limitations, work absenteeism, emotional or mental aspects, fear of treatment, and fear of the future had the strongest impact on the HRQoL. All items showed moderate confidence except for fear of treatment (low confidence). The physical, emotional, mental, and cultural aspects affected the HRQoL of patients with chronic Chagas disease. Identification of these factors is important in the development of strategies aimed at improving the HRQoL of this population.

Resumo Esta revisão sistemática objetivou discutir os principais achados sobre a confiabilidade e validade dos questionários de qualidade de vida relacionada à saúde na insuficiência venosa crônica. A busca foi realizada nas bases de dados MEDLINE, CINAHL, Web of Science, LILACS e Scopus. Os termos de busca foram relacionados a “insuficiência venosa” e “qualidade de vida”. O Chronic Lower Limb Venous Insufficiency Questionnaire (CIVIQ)-20 e o CIVIQ-14 apresentaram consistência interna adequada e foram capazes de discriminar a gravidade da doença. O Venous Insufficiency Epidemiological and Economic Study – Quality of Life (VEINES-QoL) apresentou consistência interna adequada, mas não foi capaz de discriminar a gravidade da doença. A maioria dos estudos não demonstrou associação do VEINES-QoL com o componente mental do Short Form Health Survey (SF-36). O Aberdeen Varicose Vein Questionnaire (AVVQ) apresentou confiabilidade inadequada e validade duvidosa quando comparado ao SF-36. O VARIShort demonstrou consistência interna, reprodutibilidade e validade boas, mas apenas o estudo original foi incluído. Na úlcera venosa, o Charing Cross Venous Ulcer Questionnaire (CCVUQ) apresentou confiabilidade e validade adequadas quando comparado ao Venous Leg Ulcer Quality of Life (VLU-QoL).

Abstract This systematic review aimed to discuss the main findings regarding the reliability and validity of health-related quality of life questionnaires for chronic venous insufficiency. Searches were performed on the MEDLINE, CINAHL, Web of Science, LILACS, and Scopus databases. The search terms used were related to “venous insufficiency”, and “quality of life”. The CIVIQ-20 and CIVIQ-14 instruments had adequate internal consistency and both were able to discriminate disease severity. The VEINES-QoL showed adequate internal consistency but was not able to discriminate disease severity. Most studies did not demonstrate a correlation between VEINES-QoL and the mental component of the SF-36. The AVVQ had inadequate reliability but its validity was also doubtful when compared to the SF-36. The VARIShort demonstrated good internal consistency, reproducibility, and validity, but only the original study was included. For venous leg ulcers, the CCVUQ showed adequate reliability and validity when compared to VLU-QoL.

Resumo Fundamento: A doença de Chagas leva à redução da capacidade funcional. Entretanto, o estágio em que o comprometimento funcional é detectável permanece obscuro. Objetivos: O presente estudo teve como objetivo comparar a capacidade funcional de pacientes em diferentes estágios da doença de Chagas e de indivíduos saudáveis e verificar os determinantes do consumo de oxigênio de pico (VO2pico). Métodos: Em um estudo transversal, foram selecionados 160 indivíduos, 35 saudáveis e 125 com doença de Chagas. No grupo chagásico, 61 (49%) estavam na forma indeterminada da doença, 45 (36%) com cardiomiopatia chagásica (CC) e função cardíaca preservada e 19 (15%) com disfunção cardíaca e CC dilatada. Os dados foram analisados por meio de análise de regressão univariada e multivariada. A significância estatística foi fixada em 5%. Resultados: Pacientes na forma indeterminada da doença apresentaram capacidade funcional semelhante a indivíduos saudáveis (p> 0,05). Pacientes com ChC e função cardíaca preservada apresentaram VO2pico menor que os pacientes na forma indeterminada (p <0,05), mas apresentaram valores de VO2pico semelhantes ao ChC dilatado (p = 0,46). A idade, sexo masculino, classe funcional da NYHA, pressão arterial diastólica, razão entre a velocidade do fluxo transmitral diastólico precoce e a velocidade anular mitral diastólica precoce, a fração de ejeção do ventrículo esquerdo (FEVE) e o diâmetro diastólico final do ventrículo esquerdo foram associados à capacidade funcional. Porém, apenas idade, sexo masculino, FEVE e classe funcional da NYHA permaneceram associados ao VO2pico no modelo final (R2 ajustado = 0,60). Conclusão: Pacientes com CC apresentam menor capacidade funcional do que pacientes na forma indeterminada. FEVE, idade, sexo masculino e classe funcional da NYHA foram determinantes do VO2pico em pacientes com doença de Chagas.

Abstract Background: Chagas disease leads to reduced functional capacity. However, the stage at which functional impairment is detectable remains unclear. Objectives: The present study was addressed to compare the functional capacity of patients at different stages of Chagas disease and healthy individuals and to verify the determinants of peak oxygen uptake (VO2peak). Methods: In a cross-sectional study, 160 individuals were selected, 35 healthy and 125 with Chagas disease. In the Chagasic group, 61 (49%) were in the indeterminate form of the disease, 45 (36%) with Chagas cardiomyopathy (ChC) and preserved cardiac function and 19 (15%) with cardiac dysfunction and dilated ChC. The data were analyzed using univariate and multivariate regression analysis. Statistical significance was set at 5%. Results: Patients in the indeterminate form of disease showed similar functional capacity to healthy individuals (p>0.05). Patients with ChC and preserved cardiac function had lower VO2peak than patients in the indeterminate form (p<0.05), but showed similar VO2peak values than dilated ChC (p=0.46). The age, male sex, NYHA functional class, diastolic blood pressure, ratio of the early diastolic transmitral flow velocity to early diastolic mitral annular velocity, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter were associated with functional capacity. However, only age, male sex, LVEF and NYHA functional class, remained associated with VO2peak in the final model (adjusted R2=0.60). Conclusion: Patients with ChC had lower functional capacity than patients in the indeterminate form. LVEF, age, male sex and NYHA functional class were determinants with VO2peak in patients with Chagas disease.

Resumo O objetivo deste artigo é avaliar a qualidade do sono em indivíduos durante a pandemia de COVID-19 pelo Índice de Qualidade do Sono de Pittsburgh (IQSP). Buscas foram realizadas nas bases de dados PubMed, Embase, Web of Science e PEDro, em 22 de maio de 2020. Nas publicações, foram encontrados 208 artigos e, considerando os critérios de elegibilidade, foram incluídos ao final 10 artigos, mostrando os efeitos na qualidade do sono durante a pandemia, em populações hospitalizadas, em quarentena e em profissionais de saúde. O IQSP mediu os distúrbios do sono e uma pontuação mais alta indicava uma má qualidade do sono. Foram classificados nove artigos com nível de evidência IV e um como nível III-2. Oito estudos apresentaram um risco de viés “crítico” e dois em “moderado”. Os estudos investigaram diferentes populações e descreveram os resultados como uma má qualidade do sono, considerando o IQSP, sendo os titulares de quarentena e profissionais de saúde como os mais comprometidos. Foi encontrado uma má qualidade do sono nas populações avaliadas nas publicações selecionadas, provavelmente, devido ao COVID-19 contribuir como um fator de risco para saúde mental. Intervenções psicológicas devem ser feitas para minimizar as consequências através do apoio social e capital social.

Abstract This article aims to evaluate the sleep quality in individuals during the COVID-19 pandemic by Pittsburgh Sleep Quality Index (PSQI). Searches were conducted in the PubMed, Embase, Web of Science, and PEDro databases, on May 22, 2020. In the publications, 208 articles were found and, considering the eligibility criteria, 10 articles were included at the end, showing the effects on sleep quality during the pandemic, in populations hospitalized, quarantined, and in frontline health professionals. The PSQI measured sleep disorders and a higher score indicated poor sleep quality. Nine articles were classified with evidence level IV and one as level III-2. Eight studies present a “serious” risk of bias and two in “moderate”. The studies investigated different populations and described the results as “poor” sleep quality, considering the PSQI on quarantined individuals and frontline health professionals as the most committed. A poor sleep quality was found in the populations evaluated in the selected publications, probably, due to the COVID-19 to contribute as a risk factor for mental health. Psychological interventions must be made to minimize the consequences through social support and social capital.

Abstract Aims: The present study was designed to investigate the dose-response relationship of muscular performance and anaerobic power to whole-body vibration (WBV). Methods: Nine recreationally males were subjected to five experimental conditions: A) Squat exercise (SE) without WBV; B) WBV1 [31.55 m.s-2]; C) WBV2 [159.73 m.s-2]; (D) WBV3 [319.45 m.s-2]; and E) WBV4 [567.91 m.s-2]. Before and after the experimental procedures, muscle performance was assessed by a vertical jump test and handgrip strength test and anaerobic power by Wingate anaerobic test (WT). Results: WBV2 and WBV3 increased jump relative power [Δ=0.92 ± 0.89 W/Kg (+1.97%) and Δ=1.29 ±1.79 W/Kg (+2.77%), respectively; P=0.02; effect size= 0.92; power= 0.87] and height [Δ=0.96 ± 0.73 cm (2.80%) and Δ=1.61 ± 2.36 cm (4,57%), respectively; P= < 0.01; effect size= 0.96; power= 0.99] compared to the SE [Δ=-1.28 ± 0.81 cm (-3.55%)]. There was no dose-response relationship of handgrip strength to WBV. WBV2 improved WT relative power (power/body weight) compared to the other experimental conditions [Δ= 0.61 ± 0.36 W/Kg (+ 5.25%); P < 0.01; ; effect size= 0.98; power= 0.99], and WT relative work was higher in WBV3 [Δ= 1.86 ± 5.46 KJ/Kg (+ 0.70%)condition compared to WBV1[Δ= -6.71 ± 4.03 KJ/Kg (- 2.49%) ( P= 0.03). Conclusion: These results suggest that lower limb muscular performance and anaerobic power are responsive to vibration accelerations WBV2 (159.73 m.s-2) and WBV3 (319.45 m.s-2).

Abstract Patients with Chagas cardiomyopathy (ChC) usually progress with fatigue and dyspnea. Exercise tests are valuable for the functional evaluation of these patients. However, information about the applicability of the exercise tests is scattered, and no studies have systematically reviewed the results. Thus, the present review explored the general aspects and prognostic value of exercise tests in patients with ChC. A literature search of the MEDLINE, Web of Science, CINAHL, Scopus, and LILACS databases was performed to identify relevant studies. There were no data restrictions, and articles that met the objective of the study were selected. Articles written in English, Portuguese, and Spanish were considered, and 25 articles were finally included. The peak oxygen uptake (VO2peak) was correlated with demographic and echocardiographic variables. Echocardiographic features of the left ventricular diastolic function and right ventricular systolic function appeared to be determinants of functional capacity, in addition to age and sex. VO2peak was associated with higher mortality, especially in patients with dilated ChC. The minute ventilation/carbon dioxide production slope (VE/VCO2 slope) was a strong predictor of survival; however, more studies are needed to verify this observation. Field tests showed moderate to strong correlation with VO2peak and thus may be inexpensive tools for the functional evaluation of patients with ChC. However, few studies have verified their prognostic significance. While exercise tests are useful tools for functional assessment, information is scarce regarding further considerations, and many of the criteria are based on guidelines for other heart diseases.

RESUMO Objetivo Traduzir, adaptar e validar o Patient Generated Index (PGI) para brasileiros com doença pulmonar obstrutiva crônica (DPOC). Métodos 50 voluntários com DPOC, em sua maioria homens (74%), com 73,1 ± 8,9 anos de idade, VEF1 de 52,3 ± 14,5% do previsto e VEF1/CVF de 56,2 ± 8,6% do previsto, responderam ao PGI e ao Saint George Respiratory Questionnaire (SGRQ) e realizaram teste Glittre Activities of Daily Living (Glittre ADL). Após o período de 7-14 dias, o PGI foi novamente aplicado para análise da confiabilidade relativa e absoluta. Resultados A tradução ocorreu sem alterações no questionário. A pontuação obtida no PGI apontou fraca correlação com a pontuação total do SGRQ (r = −0,44; p < 0,001) e com o domínio impacto (r = −0,40; p < 0,05), moderada correlação com o domínio sintomas do SGRQ (r = −0,55; p < 0,001) e fraca correlação com o domínio atividades (r = −0,31; p < 0,05). Foram observadas fraca correlação entre o PGI e o Glittre ADL (r = −0,30; p < 0,05) e alta confiabilidade entre as medidas do PGI (CCIr = 0,94). Conclusão Este estudo mostra que a versão brasileira do PGI é um instrumento confiável e válido para medir a qualidade de vida relacionada à saúde em pacientes com DPOC. Trata-se de uma nova forma individualizada de avaliação de qualidade de vida centrada no paciente com DPOC.

ABSTRACT Objective To translate, adapt and validate the Patient Generated Index (PGI) for Brazilians with chronic obstructive pulmonary disease (COPD). Methods 50 volunteers with COPD, mostly men (74%), with 73.1 ± 8.9 years of age, FEV1 of 52.3 ± 14.5% of predicted and FEV1 / FVC of 56.2 ± 8.6% of predicted responded to PGI, to the Saint George Respiratory Questionnaire (SGRQ) and to perform Glittre Activities of Daily Living test (Glittre ADL). After 1-2 weeks, PGI was again applied for the analysis of relative and absolute reliability. Results The translation occurred without changes in the questionnaire. The score obtained in PGI had weak correlation with the SGRQ total score (r = -0.44, p <0.001) and with the impact domain (r = -0.40, p <0.05), presented a moderate correlation with the symptoms domain of the SGRQ (r = -0.55, p <0.001) and weak correlation with the activity domain (r = -0.31, p <0.05). A weak correlation was observed between PGI and Glittre ADL (r = -0.30; p <0.05). It was observed high reliability among the measures of PGI (ICCr = 0.94). Conclusion This study shows that the Brazilian version of PGI is a reliable and valid instrument to measure health-related quality of life (HRQL) in patients with COPD. It is a new and individualized form of evaluation of COPD patient-centered quality of life.

Resumo Introdução O sobrepeso e a obesidade infantil representam alguns dos principais problemas de saúde pública no mundo, porém se observa escassez de registros de prevalência no Brasil no primeiro ano de vida. Objetivo Verificar a prevalência de sobrepeso e de obesidade no primeiro ano de vida das crianças cadastradas nas Estratégias Saúde da Família e identificar se existe diferença entre os índices peso por idade, estatura por idade, peso/estatura por idade e índice de massa corporal (IMC) por idade em relação ao sexo, à faixa etária e ao nível socioeconômico. Método Estudo transversal, com dados de peso e estatura coletados da Caderneta de Saúde da Criança. Resultados A prevalência de sobrepeso e de obesidade foi de 7,2% pelo índice peso/estatura e de 4,8% pelo IMC. Crianças com nível socioeconômico A-B apresentaram maior IMC por idade quando comparadas às crianças do nível C (p = 0,048). Crianças entre 6 e 12 meses de idade apresentaram valores superiores de peso por idade (p = 0,02) e estatura por idade (p = 0,01) quando comparadas às crianças menores de 6 meses. Conclusão A prevalência de sobrepeso e de obesidade das crianças no primeiro ano de vida depende do índice utilizado para classificação. O nível socioeconômico pode interferir nos valores do IMC por idade, enquanto a faixa etária pode interferir nos índices peso por idade e estatura por idade.

Abstract Background Childhood overweight and obesity represent one of the main public health problems in the world, but there is a scarcity of prevalence records in Brazil during the first year of life. Objective Verify the prevalence of overweight and obesity in the first year of life of infants enrolled in the Family Health Strategies, and to identify whether there is a difference in weight-per-age, height-per-age, weight/height-per-age and body mass index (BMI)-per-age in relation to sex, age group and socioeconomic level. Method A cross-sectional study was performed, in which weight and height data were collected from the Child Health Handbook. Results The prevalence of overweight and obesity was 7.2% according to the weight/height index, and 4.8% for the BMI index. Infants with an A-B socioeconomic status had higher BMI-per-age when compared to children at level C (p=0.048). Infants aged 6 to 12 months had higher weight-per-age (p=0.02) and height-per-age (p=0.01) than infants younger than six months. Conclusion The prevalence of overweight and obesity in the first year of life depends on the index used for classification. The socioeconomic status may interfere with BMI-per-age values, and the age group may interfere with weight-per-age and height-per-age indexes.

INTRODUÇÃO E OBJETIVO: o objetivo deste estudo foi investigar se a adição de vibração durante o treinamento intervalado do exercício elevaria o consumo de oxigênio VO2até o ponto necessário para controle do peso e para avaliar a influência da intensidade do estímulo vibratório para a prescrição do programa de exercícios em questão.MÉTODOS: o VO2 medido a cada respiração foi avaliado em repouso e durante as quatro condições experimentais para determinar o gasto de energia, o equivalente metabólico MET, a taxa de troca respiratória, o percentual de kcal da gordura e a taxa de oxidação de gordura. Oito mulheres jovens e sedentárias idade 22 ± 1 anos, estatura 163,88 ± 7,62 cm, massa corporal 58,35 ± 10,96 kg, VO2 máx 32,75 ± 3,55 ml O2.kg-1.min-1 realizaram treinamento intervalado duração = 13,3 min para os membros superiores e inferiores com vibração 35 Hz e 2 mm, 40 Hz e 2 mm, 45 Hz e 2 mm e sem vibração. As condições experimentais foram randomizadas e balanceadas em um intervalo de 48 horas.RESULTADOS: a adição de vibração ao exercício a 45 Hz e 2 mm resultou em aumento adicional de 17,77 ± 12,38 % do VO2, em comparação com o exercício sem vibração. Contudo, esse aumento não alterou a taxa de oxidação de gordura p = 0,42, porque a intensidade do exercício 29,1 ± 3,3 %VO2máx, 2,7 MET foi classificada como leve para indivíduos jovens.CONCLUSÃO: apesar a influência da vibração sobre o VO2 durante o exercício, o aumento foi insuficiente para reduzir o peso corporal e não atingiu a recomendação mínima de prescrição do exercício para controle do peso para a população do estudo.

INTRODUCTION AND OBJECTIVE: the aim of this study was to investigate whether the addition of vibration during interval training would raise oxygen consumption VO2 to the extent necessary for weight management and to evaluate the influence of the intensity of the vibratory stimulus for prescribing the exercise program in question.METHODS: VO2, measured breath by breath, was evaluated at rest and during the four experimental conditions to determine energy expenditure, metabolic equivalent MET, respiratory exchange ratio RER, % Kcal from fat, and rate of fat oxidation. Eight young sedentary females age 22±1 years, height 163.88± 7.62 cm, body mass 58.35±10.96 kg, and VO2 max 32.75±3.55 mLO2.Kg-1.min-1 performed interval training duration = 13.3 min to the upper and lower limbs both with vibration 35 Hz and 2 mm, 40 Hz and 2 mm, 45 Hz and 2 mm and without vibration. The experimental conditions were randomized and balanced at an interval of 48 hours.RESULTS: the addition of vibration to exercise at 45 Hz and 2 mm resulted in an additional increase of 17.77±12.38% of VO2 compared with exercise without vibration. However, this increase did not change the fat oxidation rate p=0.42 because intensity of exercise 29.1±3.3 %VO2max, 2.7 MET was classified as mild to young subjects.CONCLUSION: despite the influence of vibration on VO2 during exercise, the increase was insufficient to reduce body weight and did not reach the minimum recommendation of exercise prescription for weight management for the studied population.

INTRODUCCIÓN Y OBJETIVO: el objetivo de este estudio fue investigar si el agregado de vibración durante el entrenamiento por intervalos del ejercicio elevaría el consumo de oxígeno VO2 hasta el punto necesario para control de peso y para evaluar la influencia de la intensidad del estímulo vibratorio para la prescripción del programa de ejercicios en cuestión.MÉTODOS: el VO2 medido a cada respiración fue evaluado en reposo y durante las cuatro condiciones experimentales para determinar el gasto de energía, el equivalente metabólico MET, la tasa de cambio respiratorio, el porcentual de kcal de la grasa y la tasa de oxidación de grasa. Ocho mujeres jóvenes y sedentarias edad 22 ± 1 años, estatura 163,88 ± 7,62 cm, masa corporal 58,35 ± 10,96 kg, VO2 máx 32,75 ± 3,55 ml O2.kg-1.min-1 realizaron entrenamiento por intervalos duración = 13,3 min para los miembros superiores e inferiores con vibración 35 Hz y 2 mm, 40 Hz y 2 mm, 45 Hz y 2 mm y sin vibración. Las condiciones experimentales fueron aleatorizadas y balanceadas en un intervalo de 48 horas.RESULTADOS: el agregado de vibración al ejercicio a 45 Hz y 2 mm resultó en aumento adicional de 17,77 ± 12,38 % del VO2, en comparación con el ejercicio sin vibración. Sin embargo, ese aumento no alteró la tasa de oxidación de grasa p = 0,42, porque la intensidad del ejercicio 29,1 ± 3,3 %VO2máx, 2,7 MET fue clasificada como leve para individuos jóvenes.CONCLUSIÓN: a pesar de la influencia de la vibración sobre el VO2 durante el ejercicio, el aumento fue insuficiente para reducir el peso corporal y no alcanzó la recomendación mínima de prescripción del ejercicio para control del peso para la población del estudio.

Introdução A osteoartrite (OA) de joelhos é uma doença degenerativa complexa com alterações intra-articulares que comprometem a amplitude do ângulo do quadríceps (Q). Para mensuração dessa variável, é necessária a utilização de protocolos que apresentem confiabilidade, visando reprodutibilidade metodológica. Objetivo Avaliar a confiabilidade intra e interexaminadores das medidas clínicas e radiográficas do ângulo Q e verificar se existe relação entre o grau de OA e a magnitude deste ângulo em idosas. Materiais e métodos 23 voluntárias, tiveram o ângulo Q mensurado por 2 avaliadores, com intervalo de 48 horas. As medidas clínicas foram coletadas por meio do goniômetro universal na mesma posição adotada no exame radiográfico. Resultados A confiabilidade intraexaminador foi boa (0,722–0,763) nas medidas radiográficas e baixa (0,518–0,574) nas medidas clínicas, enquanto a confiabilidade interexaminadores foi moderada (0,634) nas medidas radiográficas e baixa (0,499) nas clínicas. A análise da correlação entre os valores radiográficos com a classificação da OA não demonstrou correlação entre os mesmos (p = 0,824 e r = -0,024). Conclusão Clinicamente, sugere-se que o exame radiográfico seja preferível para avaliação do ângulo Q de idosas com OA de joelhos. Além disto, a magnitude deste ângulo não se relacionou com o grau de acometimento da OA nesta população.

Introduction Knees osteoarthritis (OA) is a complex degenerative disease with intra-articular changes affecting the amplitude of the quadriceps angle (Q). To measure this variable, it is necessary to use reliable protocols aiming at methodological reproducibility. The objective was to evaluate the intra-examiner and inter-examiner reliability of clinical and radiographic measures of the Q angle and to investigate the relationship between the degree of OA and the magnitude of this angle in the elderly. Materials and methods 23 volunteers had the Q angle measured by two evaluators at 48-h interval. Clinical measurements were collected by using the universal goniometer in the same position adopted in the radiographic examination. Results The intra-examiner reliability was good (0.722 to 0.763) for radiographic measurements and low (0.518 to 0.574) for clinical assessment, while inter-examiner reliability was moderate (0.634) for radiographic measurements and low (0.499) to the clinics. The correlation analysis between the radiographic values with the OA classification showed no correlation between them (p = 0.824 and r = -0.024). Conclusion Clinically, it is suggested that the radiographic examination is preferable to evaluate the Q angle of elderly women with knee osteoarthritis. Moreover, the magnitude of this angle did not correlate with the degree of impairment of OA in this population.
