Is this your idea of moderate exercise?: image via stay-healthy-and-energetic.blogspot.com Research can be 'bought,' but when that happens the money (or prestige) tends to pour from a political or business pitcher. Now, I'm beginning to think that fat couch potatoes have a money pitcher too, in this case, to tell them that it's okay to sit around eating and just lifting a few fingers every once in awhile.
I am kidding, of course. But just the other day, I read that Canadian researchers, in coming up with a new health model for obese persons, actually classified the first tier of obese persons as 'healthy.' Again, the people are obese, but they are considered healthy. That group constituted 20 percent of their study. Granted, the medical needs of obese persons must be triaged in a country with universal health care, but must they use the word 'healthy?'
Now comes a study from the Taiwan National Health Research Institutes which found that persons who did an average of 92 minutes a week of moderately intensive activity had a 14 percent greater chance of living 3 years longer than those who did no activity. One cannot help getting that much exercise just by doing routine chores. The 15 minutes a day doesn't even have to be during one session.
It turns out that the Taiwan study had at least one less-than-dependable protocol. Although more than 400,000 people were surveyed, the research results were based on participant self-assessments of what and how strenuous was their exercise activity in the prior month. Though the study was longitudinal over an eight year period, there were no other variables such as diet, stress, and existing disease accounted for in the study, so that 'exercise' could be singled out as the causal factor leading to the longevity of those 14 percent.
It's doubtful that these researchers were paid off for these findings, but we all like to hear that we can achieve more with less, especially if it means we can cut those 30 minutes of daily exercise, recommended by the World Health Organization, down to 15. More time for munchies in front of the TV.
