Change Your Cell’s DNA with This Type of Exercise!

High Intensity Interval Training, or HIIT, is a very popular exercise regime, but many people have assumed that it is only for elite, highly trained athletes.  Not so!  Researchers at the Mayo Clinic have found that HIIT has even bigger benefits for older adults!

The idea of HIIT is very simple.  You exercise hard for a short while, rest for a bit, and then do it again.  You alternate between a short bout of intense exertion and a nice easy recovery.

The astonishing results of the Mayo research study were that some age-related deterioration of muscle cells had actually been reversed on people over 65 that did HIIT.  This is huge!  HIIT seemed to change a cell’s DNA in a way that boosted the muscle’s ability to produce energy.  It also triggered the growth of new muscle, helping to counteract the inevitable muscle loss that is part of the normal aging process.

These changes were more dramatic in the over-65 exercisers compared with a group of people under 30.  We rule!  

If you are considering giving HIIT a try, you should definitely check with your physician first. However, many studies have shown that intervals can be safe and beneficial for people with diabetes, heart disease, and more. 

If your physician gives you the green light, start off easy!  Begin your workout with a nice easy warm up (as always). If you enjoy walking, try walking briskly for a couple of minutes, followed by a slow stroll until you recover.  You can do the same sort of interval on a stationary bike or any piece of cardio equipment.  Gradually increase the number of intervals you do, but again, don’t overdo it at first!

I recommend that you do just one or two HIIT workouts a week, combined with light or moderate exercise on the other days.  You need to give your body time to rebuild bones and muscles to increase strength.

HIIT is not for everyone, but you may want to give it a try, now that we know how beneficial it is for us Older Wiser folks!

How Many Steps a Day: Is 10,000 Necessary?

10,000 steps…….. or not!

You have probably heard of the recommendation to walk at least 10,000 steps each day.  This is a commendable goal, but if we don’t reach that target, it’s tempting to simply give up and throw in the towel.

New research has concluded that the 10,000 step target might actually be a little on the high side, in a report from Atlantic.com. 

Researchers from Harvard gave fitness trackers to 16,000 women ages 62 to 101 and counted their steps.  They then monitored their health for a four-year period.  In a comparable study, scientists from the renowned Karolinska Institute in Stockholm gave a similar device to 851 subjects, including almost 400 men, and tracked them for 14.2 years.  In other words, one trial observed an impressively large number of subjects, and the other monitored its subjects for an impressive number of follow up years.

Surprise!  After adjusting for diet, lifestyle, and other factors, the Harvard researchers found that the women who walked about 4,400 steps a day had a 41% lower risk of premature death than the least active gals, who averaged 2,700 steps.  The Swedish study also found that the most active subjects had a 50 to 70 percent decline in mortality during a defined follow up period compared to the least active, most sedentary participants.

Walking more than 4,400 steps further on decreased the risk level moderately, and the benefits plateaued  at around 7,500.

Harvard lead author i-Min Lee says the 10,000-step goal should be lowered to encourage more people to get walking.  “If you’re sedentary,” she says, “even a very modest increase brings you significant health benefits.”

Fun fact to ponder:  The 10,000 step target isn't actually based on scientific research – it stems from a 1960s marketing campaign for a Japanese pedometer that played on the fact that the Japanese character for 10,000 resembles a man walking!  

Take away message:  Don’t give up if you aren’t walking 10,000 steps a day.  Shoot for at least 4,400 – a much more manageable target.
