Moderate-intensity aerobic training is known to positively influence the blood lipid profile, particularly through its effect on high-density lipoprotein (HDL) cholesterol. Engaging in regular moderate-intensity aerobic exercise tends to increase the levels of HDL, which is often referred to as the "good" cholesterol. HDL plays a crucial role in transporting cholesterol to the liver for excretion and can help reduce the risk of cardiovascular diseases.

By participating in this level of aerobic training consistently, individuals can enhance their cardiovascular health and improve their lipid profile, making them less susceptible to heart-related issues. The increase in HDL is a significant benefit that contributes to overall heart health.

In contrast, while moderate-intensity exercise can lead to decreases in low-density lipoprotein (LDL) and total cholesterol as well, the most notable and consistent change often highlighted in the context of moderate-intensity aerobic training is the increase in HDL levels.
