DON'T sit more than 20 mins(?) without movement break
DO include multiple weekly sessions of aerobics + balance + weight training
That's my synthesis of recent advice accumulating from many sources - especially the article cited below. The questions that follow were prompted by that article and my search for more amusing, challenging, and memorable ways of communicating important information that is too often ignored.
- Doesn't this anti-sedentary advice conflict with our customary practice of requiring students, audiences, meeting attenders, restaurant patrons, bus passengers, etc. to remain seated for at least an hour per session?
- Do traditional face-to-face classroom sessions shorten the lifespan and reduce end-of-life quality for students while ergonomically favoring instructors?
- Do synchronous online course sessions shorten the lifespan and reduce end-of-life quality more equitably for students AND instructors? Same for asynchronous course activities?
- Is the 20 minute maximum for staying seated significantly more beneficial than a 50 or 60 minute maximum?
- Why in the traditional classroom, is the instructor often the only one in the room permitted to stand or move about? Both in the earliest grades and in higher education, we expect students to remain seated and mostly immobile until the instructor gives permission to depart.
- Excerpts, quotes, references from "Don't Just Sit There," by Gretchen Reynolds, The New York Times, "A version of this news analysis appeared in print on April 29, 2012, on page SR8 of the New York edition with the headline: Don't Just Sit There"
The full-text of Don't Just Sit There charmingly and clearly summarizes rapidly accumulating evidence
