Aerobic Treadmill Exercise And Metabolism

Metabolism DisorderGlucose2 more

Overview- In this study, overweight or obese, sedentary participants (age=35-55 years, n=20) will be randomized to a 12-week control period or an aerobic exercise intervention. Those randomized into the control group will then complete the exercise intervention subsequently. The planned energy expenditure per week of exercise will be 10-12 kilocalories per kilogram of body weight per week. Participants will complete three non-consecutive exercise sessions per week. Body weight, resting metabolic rate via indirect calorimetry, peak oxygen consumption (VO2peak) through graded exercise testing, fasting blood samples, CGM, sleep and dietary habits via self-report, and physical activity monitoring will be completed at prior to and following the aerobic exercise intervention.

Effects of Simulated Passive Jogging Device on Glucose Homeostasis, Muscle Strength and Endurance...

Diabetes MellitusGlucose Metabolism Disorders1 more

Physical Inactivity and excessive sedentary behavior are risk factors for diabetes and cardiovascular disease. Movement is important for overall health. This study will assess the validity and usefulness of low risk, non-invasive wellness device, the Gentle Jogger® (GJ) that passively simulates the physical activities of jogging. The study will evaluate whether or not use of GJ modifies glycemic control and muscle strength in subjects who are known to be diabetic and those who are not. The study volunteers are subjects between the ages of 25-80yr.

Metabolic Consequences of Heterozygous Hereditary Fructose Intolerance

Hereditary Fructose IntoleranceFructose Metabolism2 more

Background: High fructose intake increases blood lactate, triglyceride and uric acid concentrations. Uric acid may contribute to insulin resistance and dyslipidemia in the general population. In patients with hereditary fructose intolerance fructose consumption is associated with acute hypoglycemia, renal tubular acidosis, and hyperuricemia. Objective: We investigated whether asymptomatic carriers for hereditary fructose intolerance (HFI) would have a higher sensitivity to adverse effects of fructose than the general population. Design: Eight subjects heterozygous for HFI (hHFI; 4 males, 4 females) and eight controls received for 7 days a low fructose diet and on the eighth day ingested a test meal calculated to provide 25% of basal energy requirement containing labeled fructose (13C fructose 0.35 g/kg), protein (0.21 g/kg) and lipid (0.22 g/kg). Total fructose oxidation, total endogenous glucose production (by 6,6-2H2-glucose dilution), carbohydrate and lipid oxidation, lipids, uric acid, lactate, creatinine, urea and amino acids were monitored for 6 hours.

The Effect of Rapid and Slow Glucose Fall on the Subsequent Glucose Production in People With Type...

Type 1 DiabetesBlood Glucose2 more

In the effort of better understanding the glucose control in people with type 1 diabetes, in-depth insight into the physiology of hepatic glucose production and its influencing factors is essential. Previously, a number of potential influencing factors of hepatic glucose production have been investigated, including insulin-on-board, low carbohydrate diet, preceding ethanol intake, exercise and multiple stimulations of hepatic glucose production. Previous post-hoc analysis of dual-hormone closed-loop systems has indicated that the rate of fall in blood glucose influences the following stimulation of hepatic glucose response. However, the rate of fall in blood glucose is highly related to insulin levels, which may explain those findings. Thus, in this study the investigators want to examine whether the different rates of fall in blood glucose with similar insulin levels on board affect the hepatic glucose response in individuals with type 1 diabetes. In the study, which will be conducted at Steno Diabetes Center Copenhagen, participants will complete two study visits. On each visit, a hypoglycemic clamp technique will be used to lower the blood glucose levels of the participants (using either a rapid or slow decline rate), whereupon hepatic glucose production will be stimulated using low-dose glucagon. The study days are divided into four phases: 1) preparation phase, 2) hyperinsulinemic euglycemic phase (stabilization of blood glucose), 3) hyperinsulinemic hypoglycemic phase (rapid or slow decline in blood glucose) and 4) post-glucagon administration phase. This design will allow the investigators to examine whether differences in hepatic glucose response exist depending on preceding rate of fall in blood glucose. We hypothesize that the rate of fall in blood glucose does not affect the hepatic glucose production.

InflammationGlucose Metabolism Disorders

Main objective : The purpose of this study is to prove that the effects of bacterial endotoxin and cytokine TNF-α, on protein loss, fatty acid release, and glucose metabolism depend on two mechanisms: Direct local effects in muscle tissue. Activation of the hypothalamo-pituitary axis and a stress-hormone response Study protocols: Acute metabolic effects of TNF-α(Beromun, Boehringer-Ingelheim Germany) vs placebo perfused into the femoral artery of the leg in 8 healthy subjects. Acute metabolic effects of placebo(saline) endotoxin(US standard reference E.Coli, endotoxin) TNF-α(Beromun, Boehringer-Ingelheim Germany) given systemically in 8 patients with hypopituitarism(to block stress hormone release) and in 8 healthy subjects all studied thrice.

Effect of Ketogenic Diet on Glucose Metabolism and Energy Expenditure in Type 2 Diabetes

Glucose Metabolism Disorders (Including Diabetes Mellitus)Energy Supply; Deficiency1 more

The study team will examine the effect of a ketogenic diet alone and ketogenic diet supplemented with oral ketones on how the body of individuals with type 2 diabetes respond to insulin, regulates insulin secretion, food intake and energetic pathways and influences body fat distribution.

Body WeightOxidative Stress13 more

The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.

Efficiency of a Nursing Intervention in Sleep Hygiene

Sleep DisorderMetabolic Glucose Disorders

Background: The relationship between the appearance of insulin resistance phenomena and insufficient or poor-quality sleep is scientifically documented. Objectives: To determine the effectiveness of an intervention based on behavioural techniques on sleep in the nursing consultation in the Primary Care setting to improve the level of HbA1c in patients diagnosed with diabetes mellitus 2 (DM2) or prediabetes. Hypothesis: Patients diagnosed with DM2 or prediabetes with poor sleep quality would improve their HbA1c levels after an intervention on healthier sleep hygiene practices. Sleeping 6 or less hours in adults diagnosed with DM2 or prediabetes would be related to worse metabolic control results. Patients diagnosed with DM2 or prediabetes who would value their sleep as poor quality would have poorer metabolic control. Methodology: Design: Not masked randomized clinical trial. Target population: Patients diagnosed up to the time of DM2 (E11) or prediabetes (R73, R73.9) with age over 18 attending the chronic nurses' follow-up visits of the Basic Health Area of Balaguer in the time range from November 2017 to December 2018. Determinations: Dependent variables: Glycemia and HbA1c. Independent variables: Sex, age, value of the Pittsburgh Sleep Quality Index (PSQI), declared hours of sleep, sleep efficiency, body mass index (BMI), pharmacologic antidiabetic treatment, changes in it, changes in diet, physical exercise and sleep hygiene. Statistical analysis: Analysis of the comparability of the groups and calculation of the confidence interval of the difference in the glycaemic values and HbA1c at the end of the follow-up, with respect to the initiation within the intervention group and within the control, and control group with respect to the group intervention.
