Running will make us look younger

Reviewed by Marta March 27, 2011 10 Comments

I’ve never been much of a long distance runner and I prefer short sharp sprints and interval training to endurance sports. The name just seems to sum it up: endurance. Hours of repetitive movements. Treadmill, hamster wheel, what’s the difference. But I might have to rethink my biases because I just found out that endurance exercise makes you look younger.

A recent study from Tel Aviv University has found that endurance exercises rejuvenates our muscles and keeps us youthful. That doesn’t seem shockingly new, but the breakthrough that the scientists made was to explain how. It seems that exercise unlocks the stem cells of our muscles.

When we age, we experience sarcopenia, a decline in mass and function of muscles, and osteopenia, which is bone loss.  That double whammy explains why, as we get older, we are more likely to fall over. Personally, I can imagine nothing worse. Leaving aside the risk of injury, it is downright embarrassing.

What’s exciting about this new research is that it suggests that muscle deterioration can be reversed. Comparing the performance of rats of different ages and sexes, they found that the number of satellite cells increased after rats ran on a treadmill for 20 minutes a day for a 13-week period. The younger rats showed a 20 per cent to 35 per cent increase in the average number of stem cells per muscle fiber retained – and older rats benefited even more significantly, exhibiting a 33 per cent to 47 per cent increase in stem cells.

Now because the researchers only gave the rats a treadmill, we don’t know if the same wouldn’t apply to any exercise including interval or weight training.  I’m willing to bet that all exercise, not just endurance, will get those muscle stem cells going. However, I will hedge my bets and make sure I incorporate some jogging and rowing (machine) into my routine.

Especially as I read that endurance exercise also improved the levels of “spontaneous locomotion” of old rats. That’s what scientists call that feeling which tells our bodies to just get up and dance. This aging rat could do with getting in touch with her inner party girl again.

    by Will running make you look older | Truth in Slimming

    [...] Marta’s article concerning running’s ability to make us look younger stirred up some controversy a couple weeks back. People argued that running actually had the opposite effect, making people look far older than they actually are, which had us scratching our heads. Could it be true? The simple answer is yes and no.

    25 years ago a friend and I decided to join a 'womens' running club'. I jogged down my hill, stopped, decided it was not for me and went back up the hill never to run again. She continued. To this day she still runs, rain, sleet or snow. Her skin today is gaunt, red, parched and wrinkled. She is very thin and osteopenic; has trouble with her feet and is constantly going to the chiropractor/podiatrist for treatments.. Her knees are shot and is considering knee replacements. Me? is great; no knee replacements, nor foot problems. So what was the benefit I ask? She likes the high she gets from running.
