[Physical exercise and atherosclerosis: proatherogenic effects of high and moderate intensity static exercise on blood lipid transport system].

Effects of high (100 and 80 kg) and moderate (60 kg) intensity static leg exercise on blood serum lipoproteins and apolipoproteins (apo) A1 and B were studied in healthy subjects (n=11) and patients with coronary heart disease and class I angina (n=11). Static leg exercise with loads exceeding 60 kg were associated with atherogenic changes of blood lipid transport system: elevation of levels of triglycerides, apoprotein B and apo B/A ratio both in healthy subjects and patients, and of total and low density lipoprotein cholesterol in patients. These post exercise changes were more pronounced in the presence of fasting hyperlipidemia and their severity increased with increase in duration of exercise. Static leg exercise did not increase concentration of high density lipoprotein cholesterol. For prevention of post exercise atherogenic dyslipidemia it is expedient to supplement strength training programs with dynamic exercise of moderate intensity.
