However, I was astounded at how exercise reduces the severity and frequency of so many diseases. The other interesting fact was the seeming correlation between extremely vigorous exercise and improved health as demonstrated by Dr. Paul Williams. Here is where the controversy starts. From the WSJ:
While Dr. Williams is well respected by other exercise scientists, he is shunned by those in the public-health field. Dr. Williams is routinely excluded from committees charged with formulating exercise guidelines, and his grant proposals are often rejected as irrelevant because few exercisers want to hear the word "more." Public-health officials also worry that touting Dr. Williams's research could discourage the sedentary from doing any exercise at all, or lure them off the couch with goals too lofty to engender success.Here is the nanny state at its worst and most pernicious, because it is the kind of low level controversy that never sees the light of day. Rather than just letting the truth get published, the public health czars think we are all too stupid to handle the truth. Of course there are down sides to very vigorous exercise, risk of injury and becoming demotivated among them; but for goodness sake, let free adults decide for themselves.
The last article talked about making the time for exercise and has some great tips to get people moving. My tip comes from what my youngest does; he really doesn't like exercise, but he often walks for an hour or more while playing a hand held video game. My research has shown that he gets as much benefit or more than I get from a vigorous 20 minute run.
