So, this guy isn't doing much good, with 2.5-3 miles walking a day at 1.8 miles/hour (1h25m to 1h40m of walking)?
I expect that, in 10 years or so, we will SE more nuanced publications about the health effects of sitting less.
Looking at chimps in nature, I expect the optimum will be something where you don't sit in the same position for hours at an end, but hobble a few meters every half hour or so and grab some fruit or groom a colleague (the latter would require significant changes in workplace ethics and law)
I get up every hour almost without fail, and walk all the way across the building to get a drink, or bathroom break, or any excuse, sometimes I do nothing at all. Often I walk to a different floor. This was on dr advice a long time ago WRT back probs and general health. I'm a heck of a lot more productive in the 10 minutes after I get back than the 10 minutes before, so its almost certainly a substantial net gain to my employer.
I do the same daily mileage as the author but compressed into my lunch hour, in addition to the above, weather permitting. I'd be interested to see shoe wear stats. When I slack off in the depths of winter or the peak of summer I can see my shoe soles not wear when I don't do a couple miles of pavement at lunch hour.
Its also interesting to look at financially, I can only get a couple hundred miles out of a pair of shoes, and I need to buy decent walking shoes not cheap junk solely based on appearance. I would guess shoe wear on a rubber belt is very low compared to concrete... then again I don't pay for whatever wear I cause to the concrete sidewalk and someone is paying for his treadmill wear directly or indirectly.
When I worked in a suburban office building I walked the nature trails and shoe wear on shredded bark was approximately zero, and it was more emotionally satisfying than dodging panhandlers in the city.
Related to above I tried wearing trail hiking boots and the wear was high on pavement. Lunch hour walks would probably be a good strategy for breaking in new boots, but it doesn't work long term for exercise.
It was an interesting article although there's plenty of space for further study.
