Whether aerobic exercise is the key to successful aging? Scientists believe that running and interval training do our cells biologically younger, but strength exercises this effect does not give.
Aerobic exercise like running and interval training can make our cells biologically younger, as the experts found out. While strength training, involving weight lifting, can produce a similar effect. This raises many questions about how different kinds of exercise affect us on a microscopic level, and whether these differences influence the choice of movements. We will remind that at the disposal of science the weight of evidence that physical activity affects the aging process. Involved in sports, older people tend to be more healthy, toned, with good musculature and less confronted with different kinds of diseases and disabilities.
But until recently, scientists were not aware of how exercise affects the body at the molecular level. In previous studies it has been proven that stress affect many genes, and the immune system, mechanism of muscle recovery and many other systems within our body. The researchers also suggested that anti-aging effect of physical activity is seen when exposed to telomeres – the end segments of chromosomes that protect DNA from damage. That length of telomeres is a good indicator of cellular functional age.
In the new study involving 124 men and middle-aged women found that aerobic exercise maintain the length of telomeres and increase them significantly slowing down aging at the cellular level. Perhaps the reason for this is the intensity. People engaged in heavy lifting, the pulse does not reach such speed, as those who runs. (READ MORE)
