Many health impacts of aging are due to inactivity—not getting old [Reblog]
From the 2 June 2015 post at The Longevity Network
This past winter I taught a course titled “Physical Activity and Aging.” It was a fun course, and really drove home an issue that I’ve known for a while, but hadn’t previously given a lot of thought: the impact of aging is identical to the detraining that happens in response to reduced physical activity and/or increased sedentary behaviour.
Aging is associated with reduced fitness, weaker bones, reduced insulin sensitivity, reduced muscle strength, and reduced balance. Lack of physical activity is also associated with all of those things. This isn’t a coincidence – many (probably most) of the health impacts of aging are not really due to aging at all.
You see, there are 2 types of aging. Eugeric aging, which you can think of as “true” aging. The stuff you simply cannot avoid as you get older (e.g. hearing loss, or reduced eyesight).
