Exercise reverses the aging process.
This post isn’t saying that exercise improves health, but that exercise reverses the aging process itself.
Much of what we call aging occurs in the finctional decline of cellular mitochondria,
“…the powerhouse that supplies energy to cells. Studies suggest poor mitochondrial function is involved in the loss of muscle mass and function commonly seen in older people.
“Older adults showed a decline in gene activity for mitochondrial function, but exercise was linked to a reversal back to levels similar to those of younger adults.
“While aging studies on worms, fruit flies and mice have shown similar results, Melov said the researchers were surprised at the extent of the results in humans.” [story]
