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).
Seawater is rich in minerals which may help confer good palatability to foods, favouring the use of smaller amounts of salt, a recognized measure of cardiovascular prevention. The aim of this study is to investigate the nutritional properties, sensory characteristics and metabolic effects of a typical Neapolitan pizza prepared with seawater (SWP) in place of common salt, in comparison with Standard traditional Pizza (StP). Methods: The nutritional characteristics and the chemical profile of the SWP and StP were assessed by chemical analyses and the use of Food Composition Tables. Twelve healthy volunteers will be recruited for a Randomized Controlled Trial, with the consumption of one StP and one SWP using a balanced crossover design. The satiating power and palatability of the two pizzas will be tested by the administration of Visual Analogue Scales. Serum glucose, insulin and sodium will be measured every 30 minutes and 3-hour urines will be collected after each meal.
This study will evaluate the impact of test carbohydrate blends on fat and carbohydrate oxidation, glucose, insulin and hunger scores in pre-adolescent boys and girls.
Whereas physical activity clearly results in improvements in glycemic control in type 2 diabetes, in individuals with type 1 diabetes (T1DM) the impact of exercise on blood sugar control is more complex. In type 1 diabetes T1DM the inability to reduce exogenous insulin levels during exercise is a key factor that contributes to an increased risk of exercise-induced hypoglycemia. Since rapid adaptation of insulin dosage may be especially difficult in patients on a multiple daily injection regimen, alternative strategies are required to improve exercise-associated glucose stability. There is increasing evidence that the combination of steady state continuous low to moderate intensity exercise with short bursts of high intensity exertion (eg in the form of sprints) is an effective, well tolerated, novel strategy to prevent exercise-related hypoglycemia. A further promising option to stabilize blood sugar levels during and after exercise may be the ingestion of fructose in addition to glucose in form of a sport drink.
