The Fountain of Youth!
“If there were a drug that could do for human health everything that exercise can, it would likely be the most valuable pharmaceutical ever developed.” – Mark Tarnopolsky, Genetic Metabolic Neurologist, McMaster University
It actually keeps us young!
Research now shows that exercise can slow down the aging process at the cellular level! When the body ages and new cells need to be created by cellular division, our DNA is copied from cell to cell and the sections of chromosomes get shorter in the process. Shorter telomeres, the end-caps of our chromosomes, mean older cells. Researchers have recently discovered a compound called “nuclear respiratory factor 1” (or NRF1) that protects telomeres from getting shorter. You can think of NRF1 as a protective coat of varnish. Bouts of moderate exercise cause the NRF1 coating to renew the protection on our telomeres, keeping them from getting shorter; effectively slowing down the aging of our cells!
It staves off depression, improves memory, and increases our capacity to learn!
Although the specific reasons why we reap these benefits are still the subject of continued research, we do know that the increased blood flow to the brain during exercise promotes the creation of new blood vessels and stimulates a release of chemicals that help reduce pain and brighten up our moods. This is likely a part of the human being’s amazing arsenal of survival-based adaptations; some of which can only be triggered by intense physical activity. The activity mobilizes our chemical resources for recovery thereby constructing a better adapted organism to tolerate such activity in the future. In effect, we stimulate our own internal powerhouse to build an even better surviving version of ourselves.
Who doesn’t appreciated more beautiful skin?
By increasing the blood flow to the skin (the biggest of our body’s amazing organs), exercise helps us get a fresh delivery of nutrients to the epidermis. These nutrients help us to heal from wear and tear, and wounds much faster.
Build up that bone density!
Resistance training or strength training (once again my favorite), causes our muscles to contract while under load. This load-bearing work puts a bit of positive pressure on our bones and promotes yet another wonderful recovery adaptation to make them more dense. That’s in addition to causing more growth of beautiful lean muscle tissue too!
Now, having read my gentle reminder this far, how can you resist the temptation to get some high quality movement practice back into your schedule this week? It makes me want to fit some bonus training in right now, but unfortunately only about half of all Americans (and transplanted Canadians like me) actually meet the recommendations for aerobic physical activity, and only 20% also do any strength training. Just 20%?! Perish the thought! How can this be?!
