Walk fast to stay ahead of the grim reaper
Mark (in blue) blocked by slow-paced tourists
I added another 10 miles to my Minnesota State Park trail tally this weekend, leaving me only a few more treks short of the century mark and another patch from the Hiking Club.
My idea of a good walk is moving at the briskest pace possible that can be sustained indefinitely. That really gets my blood pumping and thus it is most invigorating. Besides, then I get to more places faster. The tricky part is getting around those who prefer a more leisurely stroll, such as the tourists who impeded my ”push hike” to the Mendenhall Glacier outside Juneau, Alaska last year.
Some people I know have questioned my lust for long striding, but a recent report by gerontologists provides support for fast walking – it adds as many as 15 years to one’s life. Specifically, a 74-year old who walks at a gait of 1.4 meters per second (3.1 miles per hour) is more than twice as likely to be alive in 10 years than those oldsters who dawdle at 0.4 m/s (0.9 mph). Now that’s a stat for getting to where you’re going “pdq” (pretty darn quick).*
“Walk steadily and with a purpose. The wandering man knows of certain ancients, far gone in years, who have staved off infirmities and dissolution by earnest walking, hale fellows close upon eighty and ninety, but brisk as boys.”
- Charles Dickens
*Disclaimer: A more logical conclusion is that anyone who can walk this fast at age 74 must be very healthy – possibly just by luck and good genes. Thus, high gait speed is correlated with long life, not the cause of it.
Exercise reduces fatigue — a counter-intuitive effect
My RSS feed from the Curious Cat Science and Engineering Blog alerted me to news from ScienceDaily about overwhelming evidence that regular exercise increases energy levels. Professor Patrick O’Connor, co-director of the University of Georgia laboratory that analyzed 70 randomized trials on 6,807 subjects, said:
When people are fatigued the last thing they want to do is exercise.
However, the positive effect of exercise on energy was very consistent — seen in over 90 percent of the trials studied by the UGA researchers.
I feel sure this is true to some extent. I certainly feel charged up after doing a half-hour cardio-workout on my Endurance E4 elliptical. This machine features nothing very fancy for display. It only provides exercise — pure and simple at low impact.
For less anecdotal support for the hypothesis that exercise reduces fatigue, see this report from the University of Oslo. If you feel otherwise — drained by exercise, consider stocking up on a supply of jelly beans. Possibly these ‘sports beans’ ward off fatigue. I advise some skepticism if the findings prove positive, because according to ScienceDaily the study is funded in part by The Jelly Belly Candy Company.
