Exercise lengthens telomeres

xercise science professor Larry Tucker found adults with high physical activity levels have telomeres with a biological aging advantage of nine years over those who are sedentary, and a seven-year advantage compared to those who are moderately active. To be highly active, women had to engage in 30 minutes of jogging per day (40 minutes for men), five days a week. “If you want to see a real difference in slowing your biological aging, it appears that a little exercise won’t cut it,” Tucker said. “You have to work out regularly at high levels.” Tucker analyzed data from 5,823 adults who participated in the CDC’s National Health and Nutrition Examination Survey, one of the few indexes that includes telomere length values for study subjects. The index also includes data for 62 activities participants might have engaged in over a 30-day window, which Tucker analyzed to calculate levels of physical activity.

Male hormone reverses cell aging in clinical trial

"In a healthy adult, telomere length varies from 7,000 to 9,000 base pairs on average. A normal person's telomeres lose 50 to 60 base pairs per year, but a patient with telomerase deficiency can lose between 100 and 300 base pairs per year," Calado said. "In the patients who received danazol, telomere length increased by 386 base pairs on average over two years."

Could meditation really help slow the ageing process?

When the researchers crunched the data they found that the meditators’ telomeres were significantly longer than those of the controls, by an average of 10%. They then used a statistical technique called regression analysis to get an idea which factors might be directly responsible for this apparent slowing of cellular ageing. Many psychological traits were associated with having longer telomeres, including greater mindfulness skills, life satisfaction and subjective happiness. But the statistical analysis suggested that only younger age, low “experiential avoidance” and high self-compassion were directly responsible for longer telomeres.

Having more children slows down aging process -- ScienceDaily

"The slower pace of telomere shortening found in the study participants who have more children however, may be attributed to the dramatic increase in estrogen, a hormone produced during pregnancy," says Nepomnaschy who also spearheads the Maternal and Child Health Laboratory at the SFU Faculty of Health Sciences. "Estrogen functions as a potent antioxidant that protects cells against telomere shortening."
