Regular exercise improves blood pressure, insulin sensitivity, lipid profile, markers of inflammation, and abdominal fat. A team from Germany reports that, in addition, it can slow cellular aging.
The length of telomeres — the strands of DNA at the tips of chromosomes — regulates cellular aging: The longer the telomeres are, the further the cell is from programmed cell death. The length of telomeres is controlled by a complex of enzymes and proteins. The researchers allowed one group of mice to run on exercise wheels and kept another group confined; the unconfined mice had markedly increased activity of the biochemical processes that preserve telomere length and less programmed cell death in vascular endothelial tissue. The team then examine…
