The effect of pure carbohydrate, protein and fat ingestion on different aspects of short-term satiety and their relation to metabolic and cognitive performance indices were studied in 15 healthy male students. Subjects were tested in three sessions for short-term changes in blood indices, indirect calorimetry, different aspects of hunger sensations as well(More)
The effect of different carbohydrate to protein ratios in food on cognitive functions and the relation between postprandial metabolic and cognitive changes were studied in 15 healthy male students. Subjects were tested in three sessions, separated by 1 week, for short-term changes in mood states, objective cognitive functions, blood parameters, and indirect(More)
The concepts of glycemic index (GI) and glycemic load (GL) are among a new generation of so-called dynamic dietary guidelines. In contrast to classical static guidelines, these new guidelines do not primarily consider the absolute amount of energy or nutrient to be ingested within 24 h, but rather are focused on the postprandial response. It is claimed that(More)
BACKGROUND Postprandial lipemia is an independent risk factor for coronary heart disease. Single bouts of moderate exercise may lower this risk, but the minimum duration of moderate intensity exercise that still lowers postprandial lipemia is not known. We, therefore, performed a dose-response study with a normal, daily life setting, to identify the minimum(More)
There is a consensus claiming an ergogenic effect of carbohydrates ingested in the proximity of or during a performance bout. However, in performance studies, the protocols that are used are often highly standardized (e.g. fasted subjects, constant exercise intensity with time-to-exhaustion tests), and do not necessarily reflect competitive real-life(More)
BACKGROUND Carbohydrate supplements are widely used by athletes as an ergogenic aid before and during sports events. The present systematic review and meta-analysis aimed at synthesizing all available data from randomized controlled trials performed under real-life conditions. METHODS MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials(More)
The aim of this study was to investigate whether the washout length between glycemic response tests influences their reliability. A total of 3 men and 12 women performed eight identical blood glucose tolerance tests: four tests on consecutive days (short interval) and four tests spread over 20-30 days, with 5-10 days between the tests (long interval).
