This study examined the effect of the type, amount, and the frequency of feeding of carbohydrates on muscle glycogen resynthesis after running. Trained male runners performed a 16.1 km run at 80% VO2 max to decrease gastrocnemius glycogen levels. A complex or simple carbohydrate diet (approximately 3000 kcal) resulted in similar muscle glycogen levels 24 h after exercise. Forty-eight hours after exercise the complex carbohydrate diet resulted in significantly higher (p less than 0.05) muscle…

Carbohydrate loading in practice: high muscle glycogen concentration is not certain.

The results show that higher glycogen levels do not necessarily occur after classical carbohydrate-loading procedures, and that the subjects' glycogen concentrations were not clearly increased above the predepletion values following either procedure.

Dietary effects on liver and muscle glycogen repletion in exhaustively exercised rats: energy composition and type of complex carbohydrates.

A high-carbohydrate diet is more effective than a high-fat diet for further glycogen repletion in liver and skeletal muscle and dextrin was revealed to be superior to starch as a carbohydrate source in tissue glycogenRepletion.

Muscle glycogen storage after prolonged exercise: effect of the glycemic index of carbohydrate feedings.

The results suggest that the most rapid increase in muscle glycogen content during the first 24 h of recovery is achieved by consuming foods with a high GI.

Effect of Different Carbohydrate Intakes within 24 Hours after Glycogen Depletion on Muscle Glycogen Recovery in Japanese Endurance Athletes

It is suggested that carbohydrate intake of 5 g/kg BM/d is insufficient for Japanese athletes to recover muscle glycogen stores 24 h after completing a long-term high-intensity exercise.

Effect of a post exercise fat-supplemented diet on muscle glycogen repletion.

The results indicate that in horses not adapted to fat feeding,Fat supplementation slows the rate of muscle glycogen repletion, and that after an adaptation period, fat supplementation does not alter the rates of Muscle glycogenRepletion compared to the rate with a normal diet.

Carbohydrate ingestion during exercise: effects on muscle glycogen resynthesis after exercise.

The results indicate that the carbohydrate feedings taken during exercise had little effect on postexercise muscle glycogen resynthesis.

Carbohydrate loading in human muscle: an improved 1 day protocol

Findings showed that combining physical inactivity with a high intake of carbohydrate enables trained athletes to attain maximal muscle glycogen contents within only 24 h.

Carbohydrate, Muscle Glycogen, and Improved Performance.

Endurance athletes who train daily must maintain normal glycogen stores to support their training and thereby improve performance, and athletes who engage in intense daily training should consume 70% of their calories as carbohydrate.

The effects of carbohydrate loading on muscle glycogen content and cycling performance.

Muscle glycogen contents were similar at the end of the 3-hr trial, indicating a greater utilization of glycogen when subjects were CHO loaded, which may have been responsible for their improved cycling performance.

Manipulation of Muscle Glycogen Concentrations Using High and Low Carbohydrate Diets and Exercise

The results of the dietary efforts supported the findings of other investigators that muscle glycogen levels can be increased by consumption of a high carbohydrate diet, without necessarily having to stimulate the muscle for supercompensation via a depletion phase immediately preceding the loading phase as has been recommended for glycogen loading in the past.

The increase in glycogen occurred in both fibre types, but the fast twitch fibres replinished their glycogen somewhat faster than did the slow twitch fibre suggesting a higher glycogen synthetase activity.

Muscle Glycogen Synthesis after Exercise : an Enhancing Factor localized to the Muscle Cells in Man

Goldstein1 has shown that a humoral factor, which decreases the blood glucose concentration, is released during exercise and it is known that the insulin requirement decreases in diabetic subjects during exercise.

Lactate production and anaerobic work capacity after prolonged exercise.

In 3 subjects the stores of glycogen were presumed to be varied by repeated bouts of supermaximal and submaximal exercise on the bicycle-ergometer, and by diet after previously depleting the carbohydrate stores by exercise, and the ability to work anaerobically and to produce lactate decreased with decreasing amounts of available carbohydrate.

The discovery of a second glycogen synthase kinase whose activity is unaffected by cyclic nucleotides suggests the possibility that insulin may regulate the activity of a different class of protein kinase, through its own "second messenger".
