Below are a few excerpts from an interesting article from the New York Times about a study that was recently done using high intensity workouts on mice. Yes, mice.  Now the study wasn’t done on humans but the results of the study are still fascinating and it’s fun to think about mice on treadmills and whether they grunt like we do when we’re going full out.  For the full read, click the title below.  

High-Intensity Workouts May Be Good at Any Age by Gretchen Reynolds for The New York Times

Abbreviated, intense workouts may help people of any age become healthier, a new study of old mice that ran on treadmills suggests. Although the experiment involved rodents, not humans, the study found that old mice can tolerate high-intensity interval training and rapidly gain fitness and strength, even if they start off frail and exercise for only a few minutes a week.

So for the new study, which was published last month in the Journal of Gerontology A, researchers at the University at Buffalo decided to coax frail, elderly mice through a program of high-intensity interval running.

They began by gathering mice that were the rodent equivalent of about age 65 in people. Until that point, these mice had all been sedentary. Some also were frail, according to a numerical scale first developed for people that considers weight, strength, endurance, and how often and rapidly the animals move about.

The scientists tested the animals’ current health and fitness and then divided them into two groups. One, serving as a control, continued with their normal, sedentary lives.

The others began a program of high-intensity interval training on little treadmills. Mice, even elderly ones, generally like to run but, if allowed to set their own pace, will usually stroll along at a moderate, jogging-style speed. The scientists wanted their exercising animals to strain more than that. So they ramped up the incline and speed of the treadmills.

The interval-trained mice seemed in many ways younger than they had been at the start. In particular, they were stronger; when pulled backward gently by researchers, they would cling to a bar longer than at the start of the study. They also had greater endurance capacity, as well as more muscle mass in their hind legs than the sedentary animals, and they scampered faster. Few now were frail.

Perhaps most important, “the animals had tolerated the high-intensity interval training well,” despite their advanced ages, Dr. Troen says. None had found the effort impossible.

Of course, mice are not people and their capabilities do not necessarily mimic ours. Anyone, whatever his or her age, who might wish to try high-intensity interval training should talk with a doctor first, Dr. Troen says, and perhaps look for supervised interval training programs at local gyms.
