The muscle glycogen content of the quadriceps femoris muscle was determined in 9 healthy subjects with the aid of the needle biopsy technique. The glycogen content could be varied in the individual subjects by instituting different diets after exhaustion of the glycogen store by hard exercise. Thus, the glycogen content after a fat ± protein (P) and a carbohydrate-rich (C) diet varied maximally from 0.6 g/100g muscle to 4.7 g. In all subjects, the glycogen content after the C diet was higher… Expand
A study of the glycogen metabolism during exercise in man.
TLDR
The glycogen content of the quadriceps femoris muscle was determined in needle biopsy specimens taken from normal subjects in connexion with muscular work and the carbohydrate metabolism of the liver was studied before and during periods of exercise. Expand
Dietary carbohydrate, muscle glycogen content, and endurance performance in well-trained women.
TLDR
In conclusion, aerobically trained women increased muscle glycogen content in response to a high-dietary carbohydrate intake during the luteal phase of the menstrual cycle, but the magnitude was smaller than previously observed in men. Expand
Effect of low glycogen on carbohydrate and energy metabolism in human muscle during exercise.
TLDR
The effect of preexercise muscle glycogen content on the metabolic responses to exercise has been investigated and the increases in the sum of tricarboxylic acid cycle intermediates and acetylcarnitine were significantly greater during HG exercise. Expand

TLDR
Because of the paramount importance of muscle glycogen during prolonged, intense exercise, a considerable amount of research has been conducted in an attempt to design the best regimen to elevate the muscle’s glycogen stores prior to competition and to determine the most effective means of rapidly replenishing the muscle glycagen stores after exercise.

Muscle glycogen loading with a liquid carbohydrate supplement.
TLDR
Glycogen loading can be accomplished at least as effectively and more comfortably by substituting a maltodextrin drink for some of the pasta and rice in a glycogen loading diet. Expand
Human metabolic response to exercise
TLDR
An exercise and diet regime has been developed to exploit the glycogen supercompensa-tion phenomenon and so increase endurance capacity. Expand
Variation in total body water with muscle glycogen changes in man.
TLDR
19 subjects performed prolonged heavy arm and leg exercise after which they had a protein and fat diet for three days and switched to a carbohydrate enriched diet during a 4-day period, which increased body weight and total body water by 2.4 kg. Expand
Dietary carbohydrate, muscle glycogen, and exercise performance during 7 d of training.
TLDR
For cyclists and runners, consuming a moderate-carbohydrate diet over 7 d of intense training reduces muscle glycogen but has no apparent deleterious effect on training capability or high-intensity exercise performance. Expand
The effects of a glycogen-loading regimen on the capacity to perform anaerobic exercise

TLDR
The effect of a pattern of exercise and dietary modifications, which was designed to produce alterations in the muscle glycogen content, on the capacity to perform anaerobic exercise was investigated and suggests that the alterations in endurance capacity do not result from changes in the rate of anaerilic glycolytic energy production, but possibly from a change in the total capacity of the system. Expand
Effect of diet on muscle glycogen and blood glucose utilization during a short-term exercise in man.
TLDR
The muscle glycogen utilization during a short-term exercise appeared to be lower after the fat than after the carbohydrate diet, but not the concomitant blood glucose extraction, similar to those observed after a more prolonged work at the same load. Expand

TLDR
A close relationship between utilized glycogen and combusted carbohydrate was found, and it seems highly probable that at high relative workloads primarily the glycogen stores in the exercising muscles will limit the capacity for prolonged strenuous work. Expand
