High Intensity Interval Training for Better Health

Each month we will rotate the focus of  our posts.  In May we will stress health and fitness issues. Here is a preview of the type of post you can expect

It seems like every time I turn around, I see an article on the advantages of interval training, particularly cycling. You know what that is. You go flat out for a given time period, usually a minute or so, then cut back to a relaxed cadence. You've seen those guys at the track, running sprints and then stopping or just slowing to a jog or a trot. What I didn't know was those types of actions can be good for us ordinary exercisers. The New York Times recently reported that as little as a series of one minute intervals of cycling at 90 percent of the person's maximum heart rate followed by a minute of relaxed training repeated just 10 times each could have a significant impact on their fitness. And more, it actually lowered the risk of Type 2 diabetes by regulating the blood sugar. "How 1-Miinute Inervals Can Improve Your Health", February 15, 2012. IIt seems like it is a valuable means of shortening your workouts and reducing the chance of becoming diabetic.

That's not all. The Norwegian University of Science and Technology in January 2010 also reported on a study that showed that persons with Chronic Obstructive Pulmonary Disease or COPD improved their oxygen intake up to 20% after several weeks of one legged high intensity cycling sessions. "Cycling to better health, one leg at a time", press release, NTNU, January 20, 2010. Cycling one legged apparently causes the lungs to work harder. I tried to do this just to see how hard it would be and found it impossible to even turn the pedals with only one leg at a time. If you have better luck, let me know.
