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).
Objective: To study the association of low maternal plasma glucose in 2 hour 75 g oral glucose tolerance test (OGTT) in women with impaired birth weight and determinate if this result is predictive of low birth weight (<10th percentile according to the INTERGROWTH-21st newborn weight standards for gestational age/sex). Materials and methods: OGTT at 24-34 week gestation will be performed in pregnant women, the birth weight will be compared between women with low fasting plasma glucose (FPG) (<10th percentile, <65 mg/dL) and normal FPG (≥10th percentile, ≥ 65 mg/dL) also for 1 and 2-hour plasma glucose (1-h PG/2-h PG). Receiver operating characteristic curve analysis will be used to determine the optimal lower OGTT threshold for the prediction of low birth weight.
This is a large and comprehensively phenotyped cohort with fasting glycaemia where the predictive value of body composition and anthropometric measures of total and central fat distribution for postprandial carbohydrate intolerance are studied.
This study is to evaluate the capability of Raman spectroscopy as a non-invasive method for monitoring concentrations of glucose by illuminating a small spot on the skin, collecting and analyzing the return light. The glucose measurements obtained by Raman Spectroscopy are correlated with those obtained using YSI glucose analyzer and ACCUCHECK instruments.
Epidemiological studies indicate that risk of type 2 diabetes is lower when milk is consumed in the regular diet. Milk products are unique in that they produce high insulin response despite their low glycemic index. The general aim of the proposed study is to determine the effect of fluid milk on attenuating the postprandial surge in plasma glucose and triglyceride after meals and its associated physiological mechanisms. The investigators hypothesize that the consumption of one or two servings of non-fat milk added to a standard oral glucose tolerance test (OGTT) solution or the high fat tolerance test meal will attenuate postprandial hyperglycemia and triglyceridemia. The investigators hypothesize that the postulated improvement in postprandial metabolic response due to the consumption of fluid milk will be associated with increased postprandial insulin secretion as well as insulin-mediated endothelial vasodilation and whole-limb perfusion.
