Combination of exercise with high vitamin D levels slows down aging

Exercise slows down aging. This effect is greater if there is also a relatively large amount of vitamin D in the blood. This is evident from a study that recently appeared in Redox Biology. We received it from an attentive (and in many aspects well-informed) reader.

Study
Chinese endocrinologists from Capital Medical University in Beijing analyzed data from 18,738 Americans who participated in the National Health and Nutrition Examination Survey.

The study participants had answered questions about their exercise patterns, so that the researchers could divide them into a group that hardly moved at all [NO PA] and a group that moved regularly [PA].

The researchers also had access to the results of blood tests of the study participants. The Chinese not only knew the concentration of vitamin D in the blood of the study participants, but also nine values that together said something about a person's biological age. These were "albumin, creatinine, glucose, C-reactive protein, lymphocyte percent, mean cell volume, red blood cell distribution width, alkaline phosphatase, and white blood cell count".

Based on those nine values, the researchers calculated the biological age of the study participants. They then determined whether the study participants were biologically aging faster than normal.

Results
The combination of a lifestyle with exercise and a relatively high vitamin D level reduced the risk of premature biological aging by 34 percent.

The typical study participant who exercised and had a high vitamin D level was therefore 1.3 years younger than a typical study participant who did not exercise and had a low vitamin D level.

When the researchers broke down their data by age, they saw that the combination of physical activity and high vitamin D levels slowed biological aging in all age groups. The effect was slightly stronger in study participants who were younger than 65.

Conclusion
"These findings underscore the importance of outdoor physical activity in slowing down the aging process, which may have significant public health implications", the researchers summarize.

Physical activity as a longevity drug | More is better The best longevity drug we know is exercise, websites like ours have been telling you for years.	Do you want to live 12 years longer? Go for a run American researchers determined the rate of aging at the molecular level in a group of four thousand runners and non-runners.	More exercise improves quality of life on all fronts If inactive people start to get more exercise, their quality of life - both physical and mental - improves.
