[The effect of maximal and submaximal physical loads on alimentary dyslipidemia].

Short-term maximal and long-term submaximal regimens of physical exercise had been assessed for effect on serum lipoproteins in healthy subjects, in preclinical coronary heart disease (CHD) sufferers and in manifest CHD patients having food fat-induced lipemia. Fat loading caused hypertriglyceridemia in all the examinees. In healthy subjects it was associated with a rise in apo AI, while in CHD patients with relevant fall. Maximal exercise in preexisting alimentary hyperlipidemia provoked elevation of total cholesterol, triglycerides, LDL cholesterol, being atherogenic. Apo AI grew with a decrease in apo B/apo AI ratio in healthy subjects, in coronary patients apolipoprotein changes were of atherogenic origin. Prolonged submaximal exercise at the height of food lipemia resulted in lowering of total cholesterol, triglycerides and LDL cholesterol along with elevation of HDL cholesterol and apo AI both in healthy and coronary subjects evidencing anti-atherogenicity. It is noted that the response of lipids and apolipoproteins to fat and physical exercise loads was similar in subclinical and manifest CHD patients.
