A continual hydrolysis and release of FFA from the triglycerides stores of adipose tissue occurs during prolonged moderately severe exercise. The uptake and oxidation of plasma FFA by the working skeletal muscles represents a major source of energy during such exercise. During light and moderately intense prolonged exercise, lipolysis and ...

Treatment of dogs with L-thyroxine (T4) for 7 or 21 days had no influence on their body temperature, blood LA and NA concentrations and muscle glycogen content at rest. Only blood FFA and glucose concentrations were significantly higher than those before T4 administration. During exercise performed by T4-treated dogs considerably ...

Thirteen of 31 Belgian Landrace pigs developed malignant hyperthermia (MH) after breathing halothane. A short period of exercise 1 h before the administration of the triggering agent increased the incidence of the syndrome to 100% in eight similar pigs. Clinical symptoms were more marked and developed more rapidly in the ...

Increasing plasma free fatty acids decreased the degree of glycogen depletion, and increased the citrate concentration, in slow-red (soleus) and fast-red (deep portion of vastus lateralis) muscle during exercise (approx. 50% depletion of glycogen, as against 75% in control animals). There was no effect in fast-white muscle (superficial portion of ...

Eight-week restriction of physical activity markedly reduced the capacity for prolonged running. The rate of exercise-induced Tre increases was also significantly higher in comparison with control experiments. At the point of exhaustion blood glucose concentration and muscle glycogen content were similar in the control and cage-confined animals, however the rate ...

The post-exercise glycogen recovery in myocardium, liver, diaphragm muscle and musculus biceps femoris was compared in untrained and trained rats. The glycogen level in myocardium of the trained rats was significantly higher than that in the untrained ones only immediately after the exercise-test and on the second day after the ...

The Ruderman's preparation was utilized to investigate in situ some aspects of the muscular metabolism both at rest and during submaximal exercise upon bilateral sciatic nerve stimulation, and/or during perfusion with some vasodilators: papaverine, caffeine, nicergoline, bamethan. O2 and glucose uptake, the production of lactate and the glycogen level of ...

1. Concentrations of glycogen and of key metabolites have been measured in Cardium edule during aerobic and anaerobic incubation. 2. After 15 hours of anoxia only a slight carbohydrate consumption was found in the whole animal, whereas a decrease in glycogen level seemed evident in the separated adductor muscle. 3. ...

The 24-h pattern of cardiac glycogen was determined in normally active, caged male Long-Evans rats. Relatively small fluctuation was observed during a 24-h cycle with maximal difference between mean values ranging from 3.41 +/- 0.28 (dark room) to 5.15 +/- 0.19 (light room) mg glycogen/g wet wt heart, suggesting that ...

To examine the role of the nervous system in the rapid replenishment of muscle glycogen that occurs after exhaustive exercise, glycogen stores and glycogen synthetase activity of normal gastrocnemius muscles of untrained and trained guinea pigs were compared to glycogen and synthetase activity of trained gastrocnemius muscles that were denervated ...

Endurance capacity and the effects of different post-exercise states on skeletal muscle glycogen have been studied in rats trained by swimming or running and in sedentary controls. Regular endurance exercise resulted in increased skeletal muscle glycogen stores. A greater depletion was observed in trained animals than in non-trained animals after ...

Carbohydrate depletion during exercise was measured in the liver, in the three different types of skeletal muscle, and in the blood of exercise-trained and untrained rats. The acute exercise test consisted of 45 min of treadmill running of progressively increasing intensity. The training program consisted of 6 hrs of swimming ...

1. Glycogen depletion pattern in human skeletal muscle fibres was studied after bicycle exercise of varying intensity performed at different pedalling rates. Work intensities studied were equivalent to 30-150% of V(O) (2) max. with pedalling rates of 30-120 rev/min.2. Glycogen depletion increased dramatically with increasing exercise intensity; depletion was 2.7 ...

Three groups of dogs were run under different experimental conditions characterized by varying the work load or the running time. Lipid and glycogen analyses were carried out on biopsy specimens from the biceps femoris muscle before and after exercise. In addition, arterial and venous triglycerides and free fatty acids were ...

We tested the hypothesis that inhibiting glycogen degradation accelerates compound action potential (CAP) failure in mouse optic nerve (MON) during aglycemia or high-intensity stimulation. Axon function was assessed as the evoked CAP, and glycogen content was measured biochemically. Isofagomine, a novel inhibitor of central nervous system (CNS) glycogen phosphorylase, significantly ...

1. Variations in the amounts and distribution of the nicotinamide coenzymes during the life cycle of the blowfly Lucilia cuprina have been investigated. 2. The concentrations of NAD and NADP declined to a minimum in mid-pupal life, then increased threefold from this to about 600 and 40mmumoles/g. fresh wt. respectively ...
