OK. I tried to post a few things last week but they weren't showing up for some reason.... Maybe this will work!
Prolonged Sitting Leads to Glucose and Insulin Spikes

""Over the last few years, a big pile of evidence has emerged suggesting that prolonged sitting is very bad for your health. No matter how much or how hard you exercise, if you spend the rest of the day motionless at a desk or on the couch, metabolic changes take place in your muscles that increase your risk of nasty outcomes like heart disease and death. But researchers are still trying to puzzle out exactly what's going on in the muscles, in order to answer some key questions -- like how much sitting is too much, how often you need to take a break, and how much you need to move around to shake your muscles out of sedentary mode.
Travis Saunders, a researcher who is working on these very questions, has an interesting post on his blog, Obesity Panacea, describing an Australian study that offers some new insights into these questions. The gist: volunteers sat around for five consecutive hours, and partway through (after two hours) they drank a test drink with some sugar and fat in it to see how well their body responded. Some of the volunteers sat for the whole time, while others took two-minute walk breaks (at either "light" or "moderate" intensity) every 20 minutes. The results:""
Note: and additional review of the same study with a few video clips thrown in as well here:
