Exercise can Keep You Young

A new study has shown that exercise can fight ageing at the cellular level.

Researchers from Saarland University discovered that telomeres shortened less quickly in key immune cells of athletes with a long history of endurance training.

Telomere Plays an Important Role in Ageing
According to a study conducted by the British scientist it was found that telomeres present in the cell reduces in size when the cell divides.

Telomeres are protective caps on the chromosomes that keep a cell's DNA stable but shorten with age.

During the study, researchers measured the length of telomeres in blood samples from two groups of professional athletes and two groups of people who were healthy non-smokers, but who did not take regular exercise.

The findings revealed that physical exercise of the professional athletes led to activation of an enzyme called telomerase, which helped to stabilise telomeres.

Johns Hopkins Professor Awarded Louisa Gross Horwitz Prize For Telomeres Research
Carol Greider, Ph.D., the Daniel Nathans Professor genetics in the Johns Hopkins Institute and one of the world’s pioneering researchers on telomeres, has been awarded the 2007 Horwitz Prize.

This reduced the telomere shortening in leukocytes, a type of white blood cell that plays a key role in fighting infection and disease.

"This is direct evidence of an anti-ageing effect of physical exercise," the BBC quoted lead author Dr Ulrich Laufs as saying.

"Our data improves the molecular understanding of the protective effects of exercise and underlines the potency of physical training in reducing the impact of age-related disease," Laufs added.
