TLDR
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.Abstract:
IT is well known that glycogen is utilized during muscular work, but there is very little information available about the resynthesis of glycogen after exhaustive exercise. Goldstein1 has shown that a humoral factor, which decreases the blood glucose concentration, is released during exercise. Furthermore, it is known that the insulin requirement decreases in diabetic subjects during exercise.read more

Diet, Muscle Glycogen and Physical Performance
TL;DR: It has been shown that the glycogen content and, consequently, the long-term work capacity can be appreciably varied by instituting different diets after glycogen depletion.

Biochemical Adaptations in Muscle EFFECTS OF EXERCISE ON MITOCHONDRIAL OXYGEN UPTAKE AND RESPIRATORY ENZYME ACTIVITY IN SKELETAL MUSCLE
TL;DR: The increase in electron transport capacity was associated with a concomitant rise in the capacity to produce adenosine triphosphate, which may partially account for the increase in aerobic work capacity that occurs with regularly performed, prolonged exercise.

Elevation of creatine in resting and exercised muscle of normal subjects by creatine supplementation
TL;DR: Competition with 5g of creatine monohydrate, four or six times a day for 2 or more days resulted in a significant increase in the total creatine content of the quadriceps femoris muscle measured in 17 subjects, and in some the increase was as much as 50%.

Glycogen, glycolytic intermediates and high-energy phosphates determined in biopsy samples of musculus quadriceps femoris of man at rest. Methods and variance of values.
TL;DR: Variation in muscle content of ATP, ATP + ADP + AMP, phosphorylcreatine (PC), creatine (Cr), PC + Cr, and glycogen, between legs, between sites on the same muscle, or as a result of error introduced during analysis, was small compared with the between-individuals variance.

Humoral nature of hypoglycemia in muscular exercise
TL;DR: Blood and lymphatic fluid of working dogs, both normal or diabetic, are shown to develop hypoglycemic properties during exercise which can be transferred to resting preparations which appears to be quite distinct from insulin.

Muscle Glycogen in Juvenile Diabetes before and during Treatment with Insulin
TL;DR: The glycogen content in muscle biopsy specimens from normal subjects and patients with diabetes were investigated, and no significant decrease was found in the muscle glycogen compared with the normal subjects.
