On 07/11/2018 I blogged: I’m tired of Taking Crap from People for Walking Fast. Myt post concluded that, “In the end, it is important to recognize the value of walking at any intensity and pace, but if you are able and willing to pick up the pace, even for short bursts of faster walking or hill work, it will result in increased bang for the walking buck.”
Here are two more recent references related to why you might consider increasing your walking speed:
The first was from the (July 25, 2018) NY Times:
This particular health article notes specific benefits to the left ventricle and coronary arteries found in Master’s athletes and individuals who have been regular and frequent exercisers for decades.
“For lifelong heart health, start exercising early in life and keep exercising often. But even if you have neglected to exercise and are now middle-aged, it is not too late.”
Similar benefits were replicated in a two year study that arrears to be solidly supported. Randomized groups were subjected to varying levels of frequency and intensity of exercise. They found that a sedentary group showed the usual effects of time, with heart muscles, particularly their left ventricles or chambers, shrunken and less powerful than in younger people. The same changes were evident in casual exercisers. However, men and women who had exercised at least four times a week for years, or in those who were masters’ athletes had left ventricles that looked and functioned much like those of people decades younger.
I just finished reading Daniel G. Amen’s ” Memory Rescue: Supercharge Your Brain, Reverse Memory Loss, and Remember what matters Most”
Amen is a bestselling neuroscientist, psychiatrist, and founder of the Amen Clinics. He’s particularly interested in preserving and even increasing blood flow, which turns out to be advantageous for folks experiencing memory decline as well as for individuals who re concerned about aging and fitness.
“The faster we walk as we age, the longer we live and the sharper we think. An 80 year old person who walks 1 mile per hour has only a 10% chance of living until 90. But if that same 80 year old moves faster, say at 3.5 miles an hour, her or she has an 84% chance of reaching 90. (1) As walking speed goes down, so do executive function and decision-making skills. If you haven’t walked at a faster pace for a long time, start slowly and work your way up safely.”
- Stephanie Studenski et al, “Gait Speed and Survival in Older Adults”, ” Journal of the American Medical Association 305, no.1, (Jan. 2011): 50-58
It should be noted that Amen’s exercise recommendations for increasing blood flow include burst training ( intervals) , strength training, coordination activities, and mindful exercise.
