The effect of brief bodyweight exercise on acute glycemic control in healthy inactive adults.

Powley, Fiona 11 1900 (has links)
Introduction: Brief vigorous exercise can enhance glycemic control. Limited work has investigated the effect of simple, practical interventions that require no specialized equipment. We examined the effect of bodyweight exercise (BWE) on acute glycemic control using continuous glucose monitoring (Abbott Libre Sense) under controlled dietary conditions This study was registered as a clinical trial (NCT05144490). Methods: Twenty-seven healthy adults (8 males, 19 females; age: 23±3 y) completed two virtually supervised trials in random order ~1 wk apart. The trials involved an 11-min BWE protocol that consisted of five, 1-min bouts performed at a self-selected pace interspersed with 1-min active recovery periods or a non-exercise sitting control period (CON). Food intake was standardized for each participant using pre-packaged meals supplied over 24 h. Results: Mean rating of perceived exertion for BWE was 14±2 (6-20 scale). Mean HR over the 11-minute the BWE protocol was 147±14 bpm which corresponded to 75% of age-predicted maximal HR. Mean 24-h glucose after BWE and CON was not different (5.0±0.4 vs 5.0±0.5 mM respectively; p=0.39). Postprandial glucose responses were also not different between trials after ingestion of a 75 g glucose drink, lunch, dinner and breakfast meals after each intervention. Measures of glycemic variability were not different between conditions. Conclusion: A single session of BWE did not alter acute glycemic control in healthy, young adults. This study demonstrates the feasibility of conducting a remotely supervised BWE intervention using CGM under free-living conditions. Future studies should investigate the effect of repeated sessions of BWE training as well as responses in people with impaired glycemic control. / Thesis / Master of Science (MSc) / We investigated the effect of brief bodyweight exercise (BWE) on glycemic control. This refers to the ability to maintain blood sugar within a healthy range. Glycemic control was assessed with a small device called a continuous glucose monitor (CGM) that is inserted just below the skin. Healthy adults completed a virtually supervised 11-minute BWE protocol or an equivalent period of sitting. There was no difference in glycemic control measured over 24 hours following the BWE compared to sitting under standardized dietary conditions. Future studies should investigate the effect of repeated sessions of BWE training as well as responses in people with impaired glycemic control.

Índice glicêmico da dieta em pacientes com diabetes melito tipo 2 : papel na prevenção e no manejo dietoterápico da doença e associação com a presença de síndrome metabólica

Silva, Flávia Moraes January 2010 (has links)
O controle glicêmico intensificado pode prevenir e/ou retardar o aparecimento das complicações crônicas do diabetes melito (DM). O carboidrato da dieta é o principal determinante da glicemia pós-prandial, sendo o índice glicêmico (IG) e a carga glicêmica (CG) úteis para prever a resposta glicêmica aos alimentos. O objetivo deste manuscrito foi revisar criticamente o papel das dietas de baixo IG na prevenção e controle metabólico do DM tipo 2 (DMT2). O risco para desenvolvimento de DMT2 com dietas de alto IG variou de 1,21 a 1,59. A redução de 12 a 32 unidades no IG da dieta diminuiu em 0,39 a 0,50 pontos percentuais a HbA1c. Os efeitos dessas dietas no perfil lipídico e peso corporal no DMT2 permanecem controversos. Em conclusão, as evidências atuais indicam que a incorporação do IG no planejamento dietético de pacientes com DMT2 contribui para a melhora do controle glicêmico. / The tight glycemic control can prevent and/or delay the development of chronic complications of diabetes mellitus (DM). Dietary carbohydrates are the main determinant of postprandial blood glucose and glycemic index (GI) and glycemic load are used to predict blood glucose response to foods. The aim of this paper was to critically review the role of low GI diets in type 2 DM (T2DM) prevention and metabolic control. The risk for development of T2DM with high GI diets ranged from 1.21 to 1.59.The reduction from 12- 32 units in the GI of diets decreased 0.39-0.50% in HbA1c values. However, the effects of these diets on lipid profile and body weight in patients with T2DM remain controversial. In conclusion, the current evidence indicates that the inclusion of GI in the dietary planning for patients with T2DM contributes to the improvement of glycemic control.

Validade do diabetes mellitus autorreferido, prevalência de síndrome metabólica e sua relação com índice glicêmico e carga glicêmica em adultos e idosos do município de São Paulo / Validation of self-reported diabetes mellitus, prevalence of metabolic syndrome and its relationship with glycemic index and glycemic load among adults and elderly in São Paulo

Mariane de Mello Fontanelli 28 September 2015 (has links)
Introdução: O consumo de alimentos com elevado índice glicêmico e carga glicêmica tem sido associado ao aumento no risco de desenvolvimento de síndrome metabólica, importante precursor da doença cardiovascular e do diabetes mellitus tipo 2. Entretanto, esses achados ainda são inconsistentes e a utilização do índice glicêmico e da carga glicêmica para prevenção ou tratamento da síndrome metabólica e dos fatores de risco que a compõe ainda é controversa. Objetivos: Validar o diabetes mellitus autorreferido e verificar a associação do índice glicêmico e da carga glicêmica com a síndrome metabólica e seus componentes. Métodos: Foram utilizados dados provenientes do Inquérito de Saúde de São Paulo (ISA-Capital 2008) referentes a adultos e idosos de ambos os sexos residentes nessa cidade. Trata-se de estudo transversal, de base populacional, com amostra probabilística de indivíduos residentes em domicílios permanentes localizados na área urbana do município. As informações utilizadas são provenientes de um questionário estruturado, dois recordatórios alimentares de 24 horas, exames bioquímicos, valores aferidos de pressão arterial e medidas antropométricas (peso, estatura e circunferência da cintura). Foram estimadas as prevalências de diabetes mellitus e síndrome metabólica para o município de São Paulo. A validação diabetes mellitus autorreferido foi realizada mediante cálculo da sensibilidade, especificidade e valores preditivos positivo e negativo. O consumo alimentar habitual foi obtido por meio da incorporação dos dados alimentares no software Multiple Source Method. A associação entre índice glicêmico e carga glicêmica da dieta e síndrome metabólica e seus componentes foi verificada por meio de modelos de regressão logística estimados segundo faixa etária. Todas as análises levaram em consideração o desenho amostral do estudo. Resultados: As prevalências de diabetes mellitus e síndrome metabólica no município de São Paulo foram estimadas em 8,0 por cento e 30,2 por cento , respectivamente. A sensibilidade do diabetes mellitus autorreferido foi 63,8 por cento (IC 95 por cento : 49,2-76,3), a especificidade 99,7 por cento (IC 95 por cento : 99,1-99,9), o valor preditivo positivo 95,5 por cento (IC 95 por cento : 84,4-98,8) e o valor preditivo negativo 96,9 por cento (IC 95 por cento : 94,9-98,2). O índice glicêmico associou-se com a lipoproteína de alta densidade (OR: 1,16; IC 95 por cento : 1,02-1,32) em adultos e com a síndrome metabólica (OR: 1,24; IC 95 por cento : 1,1-1,37), a glicemia de jejum (OR: 1,15; IC 95 por cento : 1,01-1,31) e a pressão arterial (OR: 1,26; IC 95 por cento : 1,05-1,51) em idosos. Conclusão: O dado de diabetes mellitus autorreferido é válido, especialmente entre idosos residentes no município de São Paulo. Os resultados evidenciam a necessidade do rastreamento do diabetes mellitus em indivíduos assintomáticos que apresentem um ou mais fatores de risco para essa condição, principalmente na população adulta. No presente estudo, o IG da dieta associou-se à SM, glicemia de jejum e pressão arterial elevadas em idosos e apenas ao HDL-c baixo em adultos. As diferentes respostas entre os adultos e idosos podem sugerir que o índice glicêmico tem ação distinta entre os grupos etários. Ressalta-se que a qualidade do carboidrato parece ser mais importante do que a junção da qualidade-quantidade do carboidrato consumido para os parâmetros metabólicos avaliados na população da cidade São Paulo. / Introduction: High glycemic index and glycemic load intake has been associated with an increased risk for developing metabolic syndrome, an important precursor of cardiovascular disease and type 2 diabetes mellitus. However, these findings are inconsistent and the use of glycemic index and glycemic load for prevention or treatment of metabolic syndrome and the risk factors components is still controversial. Objectives: To validate self-reported diabetes mellitus and evaluate the association between glycemic index, glycemic load and metabolic syndrome and its components. Methods: Data were used from the Health Survey of São Paulo (ISA-Capital 2008) related to adults and elderly of both sexes living in this city. It is cross-sectional population-based study of individuals living in permanent homes located in the urban area of the municipality. Information used came from a structured questionnaire, two 24-hour dietary recalls, biochemical analysis, blood pressure and anthropometric measurements (weight, height and waist circumference). Prevalences of diabetes mellitus and metabolic syndrome were estimated for the city of São Paulo. The validation of self-reported diabetes mellitus was made by calculating the sensitivity, specificity, positive and negative predictive values. Usual food intake was achieved by the incorporation of food data in Multiple Source Method software. The association between glycemic index and glycemic load of the diet and metabolic syndrome and its components was verified by logistic regression models according to age group. All analysis took into account the sampling design of the study. Results: Diabetes mellitus and metabolic syndrome prevalences in São Paulo city were 8.0 per cent and 30.2 per cent , respectively. The sensitivity of self-reported diabetes mellitus was 63.8 per cent (95 per cent CI: 49.2 to 76.3), specificity was 99.7 per cent (95 per cent CI: 99.1 to 99.9), the positive predictive value was 95.5 per cent (95 per cent CI: 84.4 to 98.8) and the negative predictive value was 96.9 per cent (95 per cent CI: 94.9 to 98.2). Glycemic index was associated with high density lipoprotein cholesterol (OR: 1.16; 95 per cent CI: 1.02 to 1.32) in adults and with metabolic syndrome (OR: 1.24; 95 per cent CI: 1.1 to 1, 37), fasting blood glucose (OR: 1.15; 95 per cent CI: 1.01 to 1.31) and blood pressure (OR: 1.26; 95 per cent CI: 1.05 to 1.51) in elderly. Conclusion: Self- report diabetes mellitus data is valid, especially among elderly people living in São Paulo. The results show the need for diabetes mellitus screening in asymptomatic individuals who have one or more risk factors for this condition, especially in adults. Glycemic index was associated with metabolic syndrome and elevated fasting blood glucose and blood pressure in elderly and only with low high density lipoprotein cholesterol in adults. The different responses among adults and elderly may suggest that glycemic index has distinct action between age groups. Carbohydrate quality seems to be more important than the joint quality-quantity of the ingested carbohydrate for metabolic parameters evaluated in the population of São Paulo city.
