The myths surrounding pre-exercise carbohydrate feeding.
BACKGROUND/AIMS Carbohydrate ingested 30-60 min before exercise may result in hypoglycaemia during exercise, a phenomenon often called rebound or reactive hypoglycaemia. There is considerable confusion regarding pre-exercise carbohydrate feeding with advice that ranges from 'consume carbohydrate in the hour before exercise' to 'avoid carbohydrate in the 60 min prior to exercise'. METHODS We a...
متن کاملEffects of carbohydrate feeding before and during prolonged exercise on subsequent maximal exercise performance capacity.
The study examined the effect of carbohydrate ingestion on exercise performance capacity. Nine male cyclists performed two separate trials at 70% VO2max for 60 min followed by a maximal ride for 10 min. During trials subjects were fed either an 8% glucose solution (CHO) or a placebo solution (PL), which were administered at rest and during and immediately after submaximal exercise. Statistical ...
متن کاملSkeletal muscle metabolic gene response to carbohydrate feeding during exercise in the heat
BACKGROUND Heat stress down-regulates mitochondrial function, while carbohydrate supplementation attenuates the exercise induced stimulation of mitochondrial biogenesis in humans. The effects of exogenous carbohydrate during exercise in the heat on metabolic mRNA have not been investigated in humans. The purpose of this study was to determine the impact of exercise with and without carbohydrate...
متن کاملCaffeine increases exogenous carbohydrate oxidation during exercise.
Both carbohydrate (CHO) and caffeine have been used as ergogenic aids during exercise. It has been suggested that caffeine increases intestinal glucose absorption, but there are also suggestions that it may decrease muscle glucose uptake. The purpose of the study was to investigate the effect of caffeine on exogenous CHO oxidation. In a randomized crossover design, eight male cyclists (age 27 +...
متن کاملRegulation of muscle carbohydrate metabolism during exercise.
This review examines the mechanisms that regulate muscle carbohydrate metabolism during exercise. Muscle carbohydrate utilization is regulated primarily by two factors, namely, delivery of substrate to the glycolytic pathway either from glycogenolysis or from transport of extracellular glucose into the fibers, and formation of triosephosphate by phosphofructokinase. The regulation involves the ...
