A recent animal study from researchers in the Department of Internal Medicine at the University of Utah in Salt Lake City investigates the role of DNA damage in blood vessels and the aging cardiovascular system.
However, understanding precisely how exercise benefits cardiovascular health has proven more challenging. The new study focuses on one of the likely mechanisms: DNA damage.
Telomeres in cells that line blood vessels are particularly sensitive to damage by a force called "shear stress."
The current study from the University of Utah investigated whether exercise might reduce cardiovascular risk by minimizing DNA damage and protecting telomeres.
