ABSTRACT
In the evaluation of the mechanisms of how exercise and training modify plasma lipoproteins, the lipolytic enzymes play a key role. The association of lipoprotein lipase with the elevation of the high density lipoprotein fraction and simultaneously with the decrease of very low density lipoprotein triglycerides has been clarified. Despite the numerous studies on the association between physical training and plasma lipoproteins, quite a few studies exist on the mechanisms might mediate the changes. Prolonged exercise increases blood free fatty acids as an indication of the activation of the hormone sensitive lipase in the adipose tissue. Regular exercise training increases hormone sensitive lipase in the adipose tissue mobilizing adipose tissue fatty acids for the use in the muscles as energy. Exercise training has both acute and long-term effects on many of the hormones participating in the regulation of lipolytic enzymes.
