Glycogen loading alters muscle glycogen resynthesis after exercise.
This study compared muscle glycogen recovery after depletion of approximately 50 mmol/l (DeltaGly) from normal (Nor) resting levels (63.2 +/- 2.8 mmol/l) with recovery after depletion of approximately 50 mmol/l from a glycogen-loaded (GL) state (99.3 +/- 4.0 mmol/l) in 12 healthy, untrained subjects (5 men, 7 women). To glycogen load, a 7-day carbohydrate-loading protocol increased muscle glyco...
متن کاملHigh rates of muscle glycogen resynthesis after exhaustive exercise when carbohydrate is coingested with caffeine.
We determined the effect of coingestion of caffeine (Caff) with carbohydrate (CHO) on rates of muscle glycogen resynthesis during recovery from exhaustive exercise in seven trained subjects who completed two experimental trials in a randomized, double-blind crossover design. The evening before an experiment subjects performed intermittent exhaustive cycling and then consumed a low-CHO meal. The...
متن کاملGlycogen loading: advantages but possible disadvantages.
Carbohydrate loading enables an athlete to build up stores of muscle glycogen. Such raised levels increase work times and are therefore of real benefit to long-distance runners. It is unclear how frequently the regimen can be repeated with the same advantageous results. There are possible disadvantages in the regimen, and even dangers in older subjects.
متن کاملAstrocytic glycogen-derived lactate fuels the brain during exhaustive exercise to maintain endurance capacity.
Brain glycogen stored in astrocytes provides lactate as an energy source to neurons through monocarboxylate transporters (MCTs) to maintain neuronal functions such as hippocampus-regulated memory formation. Although prolonged exhaustive exercise decreases brain glycogen, the role of this decrease and lactate transport in the exercising brain remains less clear. Because muscle glycogen fuels exe...
متن کاملEffect of time of carbohydrate ingestion on muscle glycogen resynthesis after exhaustive exercise in rats.
We studied the optimal time of carbohydrate ingestion required to restore muscle glycogen storage after exhaustive exercise in rats. The animals were divided into 4 groups (IN0, IN30, IN60 and IN120), each receiving 30% glucose solution (30 g/kg body weight) through a stomach tube 0, 30, 60 or 120 minutes after exercise. Six hours after administration of glucose, the glycogen concentration in t...
