Kosher Fitness

Readers of this blog know that I have written quite a bit about walking as exercise for older adults. The benefits are many and go beyond simple cardio activity; walking is associated with better health outcomes and disease prevention. Still, older adults wonder if walking is good enough; this was the topic of a post nearly three years ago. It is good, but the more intense it is, the greater impact it has on our health.
NBC News recently reported on a study that came out earlier this week in British Journal of Sports Medicine about walking and diabetes. In particular, it dealt with Type II Diabetes; according to the Mayo Clinic, Type II Diabetes is a condition that happens because of a problem in the way the body regulates and uses sugar as a fuel. That sugar also is called glucose. This long-term condition results in too much sugar circulating in the blood. The National Institutes of Health notes that a person is more likely to develop Type II Diabetes if they are not physically active and are overweight or have obesity. Extra weight sometimes causes insulin resistance and is common in people with Type II Diabetes.
The upshot of the new study is that it is now possible to quantify what kind of walking (slower vs faster) can prevent the development of Type II Diabetes. Walking at a pace of 2.5 mph can lower the risk by 15%. The faster the pace, the bigger impact it will have: 3-4 mph lowers the risk by 24% and over 4 mph reduces the risk by 39%. Obviously, the more vigorous the activity, the more it influences our overall health in addition to our chances of getting Type II Diabetes–but speed isn’t everything. Guidelines recommend that adults exercise for 150 minutes per week; so if a person walks vigorously, but only for 30 minutes a week, they are much less likely to make a dent in their chances of developing the disease.
As always, before beginning an exercise regimen, it is important to talk with your physician. Most doctors recommend walking because it requires no equipment (except for supportive shoes) and no instruction. Now there is another reason to like walking: we can help prevent Type II Diabetes.
