Exercise is Good for Cholesterol
A new study has uncovered details as to why exercise is beneficial for heart health and blood lipid levels at any age. The study reported in the journal Nutrients compared the physical activity and lipid levels of 45 older adults aged 60 to 80 with 63 younger adults aged 20 to 35. In addition to measuring high-density lipoprotein (HDL or “good” cholesterol), the scientists also considered the size of the HDL particles, which provides insights into the type and functionality of HDL as it absorbs excess cholesterol from the blood and transports it back to the liver to be recycled or excreted in bile. Researchers found that, regardless of whether the individuals were younger or older, the physically active participants exhibited higher HDL, as well as more of the types of HDL that are cardio-protective, and a greater capacity to process cholesterol back to the liver, which is one of the key anti-atherosclerosis functions of HDL.
