Filter by:Physical exercise (PE) significantly influences insulin sensitivity (IS), glucose control and overall metabolic health. While PE effectively enhances IS and glucose regulation, the timing of nutrient intake, before and after exercise, plays a crucial role in modulating its effects. The aim of this study is to evaluate how pre- or post-evening exercise carbohydrate (CHO) ingestion influences glucose metabolism and substrate oxidation (fat/CHO) during exercise and after exercise in athletes during the nocturnal period and the morning after during an oral glucose tolerance test (OGTT).
The main objective of this project is to study the diurnal variation of the effect of exercise on glycemic metabolism and fat oxidation in humans.
Giving personalised dietary advice will help mitigate the postprandial increases in TG and glucose levels, and will assist in the battle against the increase in nutrition-related diseases, such as cardiovascular diseases. Being able to predict postprandial responses, will be a first step to personalised dietary advice. The primary objective of this study is to validate the prediction model on the effect of a standardized mixed meal challenge on postprandial TG levels in a heterogenous group of middle-aged, overweight to obese individuals. The secondary objectives are 1) to improve the accuracy of the predicted postprandial TG responses by increasing the number of postprandial TG measurements, 2) to determine which parameters can improve the accuracy of the predicted postprandial TG responses, 3) to determine if we can predict the effect of a standardized mixed meal challenge on postprandial glucose levels in a heterogenous group of middle-aged, overweight to obese individuals, and 4) to determine which parameters can improve the accuracy of the predicted postprandial glucose responses. Another objective is to validate dried blood spots postprandial triglyceride concentrations against venous blood concentrations. There are minor risks for the research subjects of this study. Research subjects will invest approximately 13.5 hours in the study. They will visit the Wageningen University research facility three times and Hospital Gelderse Vallei once.
This study is designed to investigate the health impact of a vegan diet compared to a usual, omnivorous diet. The investigators plan to study these diets in twins, where one twin follows a vegan diet and the other twin follows an omnivorous diet, thus the investigators control for genetic differences that might impact the effect of the diet.
The effects of a 10g/day collagen hydrolysate for a period of 4 weeks on glycemic control and cardiovascular health in a parallel design study using overweight/ obese men and women who are likely to have a disturbed lipid and glucose metabolism and increased risk to develop cardiovascular disease and/or Type- 2 diabetes.
Nonfermenting Gram-Negative Bacilli (NFGNB) are aerobic, non-motile, non-lactose fermenting, oxidase-negative, catalase-positive coccobacilli that pose a serious threat to critically ill patients. Primarily Pseudomonas aeruginosa (PA) and Acinetobacter baumannii (AB), are NFGNB which are potential multi-drug resistant (MDR) pathogens that are related to ventilator-associated pneumonia (VAP). In Nonfermenting Gram-Negative Bacilli (NFGNB) infections, which are potential multi-drug resistant (MDR) pathogens, pathogenesis is determined not only by bacterial virulence factors but more importantly by the interaction between bacteria and the host immune system. Thanks to their direct immunomodulatory properties, lipoproteins and lipids bind and neutralise toxic bacterial substances. During the acute phase response and inflammation, HDL presents significant structural and functional changes. This study was planned to evaluate the relationship between the changes of the serum lipid metabolism and other inflammation markers with the antimicrobial resistance status and the results in NFGNB VAP patients. Also, we aimed to investigate whether there is a difference in the clinical characteristics of the patients depending on the resistance profile of NFGNB.
Background: Among the risk factors associated with aging, a special highlight has been attributed to cardiovascular dysfunctions, insulin resistance, central obesity and dyslipidemia, which is marked by low levels of cholesterol (high density lipoprotein) and in particular by high levels of plasma triglycerides. Individuals with high levels of plasma triglycerides tend to have a prolonged postprandial hypertriglyceridemia after a fat-meal challenge, which would potentially further increase the risk associated with cardiovascular disease. Due to the impact of aging and its associated risk factors on the older adults health, several strategies have been proposed to avoid the progression of chronic diseases. These diseases are frequent in this population, especially the ones that resides in long-term institutions and they are mainly characterized by sedentary lifestyle and functional inability. Systematic reviews have shown that the implementation of physical activity programs associated with a favorable dietary pattern may benefit the lipid profile of the older adults. Moreover, it is suggested as a primary strategy, the realization of physical exercise as a therapy for this disease. In the physical exercise programs aspects, unconventional modalities such as Capoeira, which is practiced in more than 150 countries, it has aroused interest in the scientific research. Characterized by a system composed by attack and defense movements and from Afro-Brazilian origin, Capoeira combines sports elements of the fight, gymnastics, dance and musicality. However, there is no study investigating the effect of Capoeira training on the lipid profile of older adults, which would have an important clinical application in the health of this population, especially living in conditions of sedentarism and frailty in long-term institutions. Aim: The present study analyzed the effects of twelve weeks of Capoeira training on the lipid profile of advanced-age frail adults of a long-term institution, which are characterized by sedentary lifestyle and affected by several diseases. Methods: Participants were assigned into two groups (CONTROL: n = 07; 82.4±13.6 years and CAPOEIRA: n = 07; 79.4±6.9 years). The CAPOEIRA group performed twelve weeks of Capoeira training program, being twice a week lasting 60 minutes each at light to moderate intensity. Samples of 10 ml of blood were collected from participants' antecubital vein at the pre- and post-intervention moments in both groups. Plasma concentrations of triglycerides, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol were evaluated using the enzymatic colorimetric method. Anthropometry measures were performed and to internal control the energy consumption evaluations were carried out through daily food diaries during intervention period.
Elevated levels of plasma triglycerides are increasingly recognized as an important causal risk factor for cardiovascular disease and associated pathologies. Lowering plasma triglycerides may therefore be a therapeutic target to lower cardiovascular disease risk. With this study the investigators want to examine the effects of fasting on adipose tissue metabolism in humans.
The objective of this study is to assess whether intake of baked and then chilled potatoes over a 24-h period, compared to intake of isocaloric, carbohydrate (CHO)-matched foods low in fiber and resistant starch (RS), will increase insulin sensitivity, breath hydrogen and satiety, and decrease hunger and free fatty acid (FFA) levels in overweight or obese men and women at risk for metabolic syndrome and diabetes mellitus.
The interventional study will evaluate the effects of a regularly consumption of barley and oat flakes in crude and roasted form on the glucose and lipid metabolism as well as the postprandial saturation. Moreover, the study will evaluate the effect of a regularly consumption of barley and oat flakes on the glucose and lipid metabolism over a period of three weeks. All participants will run through each intervention (cross-over design). Inbetween these intervention periods there will be wash-out phases. In total there will be four interventions: crude oat flakes, roasted oat flakes, crude barley flakes and roasted barley flakes. The comparison will be made against white toastbread. The study participants will visit the study centrum before and after each intervention over an entire period of 27 weeks.
