Summary: Hyperthermia and dehydration may contribute to increased glycogenolysis during exercise and poor glycogen resynthesis during recovery.

Summary: The study compared the impact of two commonly consumed beverages on exercise recovery, finding differences in blood glucose and insulin response, muscle glycogen re-storage, protein synthesis, and other markers, but no significant differences in physiological and performance outcomes between the two beverages.

Summary: The introduction of the needle muscle biopsy technique in the 1960s revolutionized the study of muscle tissue in exercising humans. The role of muscle glycogen content and blood glucose concentration in fatigue during prolonged exercise is still a matter of debate.

Summary: This study compares the effect of 30 g potato protein and 30 g milk protein on muscle protein synthesis in healthy, young males. The results show that both potato and milk protein can increase muscle protein synthesis rates at rest and during exercise recovery.

Summary: Daily muscle glycogen recovery is crucial for athletes. This study used C-13-MRS to investigate the impact of carbohydrate intake on muscle glycogen recovery for 24 hours after exercise. The findings suggest that a carbohydrate intake of 5 g/kg BM/d is insufficient for Japanese athletes to recover muscle glycogen stores within 24 hours.

Summary: Belt electrode skeletal muscle electrical stimulation (B-SES) can prevent denervation-induced muscle atrophy in multiple muscles. Low-frequency electrical stimulation maintains mitochondrial quantity and enzyme activity, suppressing muscle protein degradation.

Summary: Muscle glycogen state and carbohydrate supplementation can impact responses to high-intensity interval training (HIIT). This study found that CHO ingestion improved performance and did not suppress fat oxidation during HIIT in a glycogen depleted state. Further research is needed to understand the significance of altered muscle oxygenation patterns during exercise.

Summary: Divergent selection on Pectoralis major pHu in chickens resulted in the creation of pHu+ and pHu- lines, with differences in carbohydrate and protein metabolism which likely affect muscle growth and energy storage capabilities. These differences were already present at hatching, indicating early mechanisms involved in the establishment of phenotypes.

Summary: This study found that administration of d-Allulose improved aerobic performance and recovery from exhaustion in mice. It increased maximal aerobic speed, decreased blood lactate levels, and increased liver glycogen levels. It also improved insulin sensitivity. Overall, d-Allulose administration had similar effects to exercise training.

Summary: The study investigated skeletal muscle metabolism and repeated sprint performance changes in elite female football players during match play. The results showed marked glycogen depletion in both fiber types at the end of the match, potentially explaining fatigue. Repeated sprint ability decreased after intense periods in both halves, possibly due to muscle metabolite perturbations.

Summary: The study demonstrated that melatonin administration increased energy substrate availability before exercise, improved exercise tolerance, and accelerated the recovery of muscle energy substrates after exhaustive swimming exercise, possibly through GLUT4 and FAT/CD36.

Summary: The study found that ingesting a large amount of glucose immediately after exercise increased insulin secretion and enhanced muscle glycogen recovery, whereas frequent and small amounts of glucose intake was shown to enhance liver glycogen recovery.

Summary: The study explored the impact of myofibrillar protein synthesis (MyoPS) and gene signaling on recovery from 300 muscle-damaging eccentric contractions. Elevated MyoPS rates were observed during recovery with activation of inflammatory and regenerative signaling pathways. A nutritional intervention accelerated recovery, although MyoPS and gene signaling remained unchanged compared to placebo, indicating they do not explain accelerated recovery from muscle damage.

Summary: This study compared the effects of flavored dairy milk based recovery beverages on markers of gastrointestinal and immune status, and subsequent recovery optimization. The results showed that MBSB compared to CM was more likely to cause carbohydrate malabsorption and gut discomfort, but there were no significant differences in gastrointestinal integrity and immune response between the two.

Summary: Human exposure to fluorine from multiple sources can lead to metabolic disorders, particularly in muscle cells. This study investigated the impact of fluoride exposure on enzymes involved in muscle glycogen metabolism. It was found that fluoride exposure altered energy state, enzyme expression, and glycogen deposition in cells.
