Lipid metabolism and exercise
The regulation of lipolysis in adipocytes involves coordinated actions of many lipid droplet (LD)-associated proteins such as perilipin, hormone sensitive lipase (HSL), adipose triglyceride lipase (ATGL), and its activator protein, CGI-58. Recently, the author and my colleagues described the cellular origin and physiological significance of micro LDs (mLDs) that emerge in the cytoplasm during a...
متن کاملExercise and postprandial lipid metabolism.
Energy expenditure and fat oxidation are both profoundly increased in exercise. In absolute terms, fat oxidation is greatest during exercise of moderate intensity (60-65 % maximum 0 2 uptake, vo2,,) when subjects following a mixed diet may oxidize between 0.3 and 0.7g fat/min, rFpresenting up to 60% of energy expended (Saltin & Astrand, 1993). Because the capacity of muscle fibres to synthesize...
متن کاملExercise Intensity Modulation of Hepatic Lipid Metabolism
Lipid metabolism in the liver is complex and involves the synthesis and secretion of very low density lipoproteins (VLDL), ketone bodies, and high rates of fatty acid oxidation, synthesis, and esterification. Exercise training induces several changes in lipid metabolism in the liver and affects VLDL secretion and fatty acid oxidation. These alterations are even more conspicuous in disease, as i...
متن کاملThe Effect of Chronic Intake of L-carnitine L-tartrate on Lipid Metabolism during Aerobic Exercise
Background & Aims: Despite 20 years of research, there is no compelling evidence about the effect of carnitine supplementation on improving physical performance in healthy subjects. The aim of this study was to determine the effect of long term consumption of acute L-carnitine L-tartarate (LCLT) on fat metabolism and aerobic capacity. Methods: A total of 28 healthy nonathlete male students rece...
متن کاملSkeletal muscle lipid metabolism in exercise and insulin resistance.
Lipids as fuel for energy provision originate from different sources: albumin-bound long-chain fatty acids (LCFA) in the blood plasma, circulating very-low-density lipoproteins-triacylglycerols (VLDL-TG), fatty acids from triacylglycerol located in the muscle cell (IMTG), and possibly fatty acids liberated from adipose tissue adhering to the muscle cells. The regulation of utilization of the di...
