A new study is showing that there may be additional benefits to exercise deep down at the cellular level.

Dr. Ulrich Laufs, from the University of Saarlandes in Saarbrücken, Germany has found that the cells of 50-year-old athletes appeared biologically younger (sometimes up to decades younger) than healthy people of the same age.

ABC News reports:

Laufs and his colleagues decided to tackle the problem by studying exercise’s chemical influence on telomeres — caps, that act as a sort of buffer at the end of chromosomes that protect DNA from damage. A young cell typically has long telomeres, but telomeres begin to degrade and fray as it ages. Older people typically have shorter telomeres in their cells. If telomeres in a cell are too short, the cell dies.
