Exercise can reduce hyperlipidemia. At first, it was thought that hyperlipidemia refers to the increase of total cholesterol and/or triglyceride levels in plasma. Later, it was found that hyperlipidemia is essentially a manifestation of lipid metabolism disorder. In recent years, scholars have gradually realized that the decrease of plasma high density lipoprotein is also a disorder of lipid metabolism, and classified it into the category of hyperlipidemia. Therefore, some scholars suggest that it is more reasonable to call hyperlipidemia dyslipidemia, and think that this name can reflect the disorder of lipid metabolism more comprehensively and accurately. Hyperlipidemia should specifically include: increased plasma total cholesterol and/or triglyceride levels, increased low-density lipoprotein and decreased high-density lipoprotein.

A large number of studies at home and abroad show that regular exercise can make beneficial changes in blood lipid and lipase: high-density lipoprotein (HDL) increases, low-density lipoprotein (LDL) and total cholesterol (TG) decrease, lipoprotein lipase (LPL) activity increases, and total cholesterol clearance rate increases. Regular exercise can also change the distribution of HDL and LDL subtypes: HDL2 subtype increases, while SLDL subtype with strong atherosclerosis decreases. Moreover, there is a linear dose-response relationship between the increase of exercise intensity and running distance and the increase of blood HDL-C. These changes can be observed in most men, women and middle-aged and elderly people. Therefore, exercise is a simple and low-cost method, which can not only prevent dyslipidemia, but also prevent hypertension and osteoporosis, and is an effective way to reduce hyperlipidemia.
