Scientific American published an article in the August 2013 edition titled, Why Exercise Works Magic by Shari S Bassuk, endocrinologist, Timothy S Church, director of Preventative Medicine Research Laboratory at LSU, and JoAnn E Manson, Professor of Women’s Health at Harvard. (Those bios are criminally short compared to how much these three have accomplished.)
This article teaches that regular exercise can actually change the body on a molecular level, improving human life in nearly every conceivable way. To read the whole article, which is very worth the time, subscribe to Scientific American
Here are a few ways exercise improves the body:
– Nervous System: Improvement in cognitive function, especially aerobic exercise for older adults.
– Immune System: Hitting the gym regularly helps protect from inflammation.
– Musculoskeletal System: Being in good aerobic shape helps reduce normal fatigue by increasing muscle efficiency as well as strengthening bones against breaking.
– Genetics: The full extent of genetic changes wrought by exercise are not entirely understood, but the results are promising and include reduction in cancer rates.
– Endocrine System: Decreased risk of type 2 diabetes as a result of improved responses to insulin.
Despite these benefits, the article continues on to state that barely more than half of Americans get the minimum amount of required daily activity, which is 30 minutes of moderate activity five or more days per week. What is the benefit of meeting that 30/5 requirement? An extra 3.4 years of life expectancy!
So get up and MOVE, and don’t just take my word for it.
