How does regular aerobic training typically affect HDL cholesterol?

• A. Aerobic training tends to increase HDL cholesterol
• B. Aerobic training has no effect on HDL
• C. Aerobic training decreases HDL
• D. Aerobic training reduces HDL to baseline

Answer: (A)

Regular aerobic training tends to raise HDL cholesterol. This happens because consistent endurance exercise boosts lipid metabolism and reverse cholesterol transport. It increases the production and circulation of HDL particles, enhances enzymes involved in HDL maturation (like LCAT), and can raise the levels of apolipoprotein A-I, which is core to HDL structure. At the same time, aerobic activity lowers triglycerides and VLDL, which shifts lipid particles toward more HDL-rich profiles and can shift HDL toward larger, more protective forms (HDL2). In practical terms, you often see a modest increase in HDL-C—typically around a few percent to about 10%—especially with higher volume or intensity and in those with lower initial HDL. This combination of effects helps explain why regular aerobic training is associated with a healthier lipid profile.
