After another gorgeous 6 am Wednesday trail run with my favorite group of ladies, I found an article in my inbox titled "
Exercise and the 'Good' Bugs in our Gut", by New York Times author Gretchen Reynolds. What a perfect time to be reading about the benefits of exercise on our gut microbiome! Not to mention, these are two of my FAVORITE subjects.
(Photo above is not me, although I'd take it as a compliment if you thought it was :). )
Although the research discussed is preliminary, there does appear to be a positive correlation between exercise and the diversity of the bacteria found in the gut. Diversity in this gut bacteria is a VERY good thing. Much in the same way when we are exposed to germs or bacteria when we come in contact with people who have colds or 'bugs', when we have a diverse microbiome in the gut, we are better able to adapt to potential contaminants in the things we eat. They may also help us process and digest foods better, but that's another topic altogether.
The study reported on men of ranging BMIs and activity levels from your average Joe to rugby players (read: super athletes). It takes a lot of heart and a lot of strength to exercise at the capacity required for rugby players. However, in looking at the trend of increasing energy expenditure via exercise, it is clear that the more active participants in this study harbored a much more diverse bacteria colony than did the lesser active participants.
Perhaps this could be influenced by the fact that active people require more calories, resulting in them eating more food than your average person. These people may be exposing themselves to more diverse bacteria simply by eating more food, however, exercise is the root of the increased need for calories. Since I am an advocate for exercise, I will leave it at that.
The bottom line for me is exercise is, once again, encouraged for improved maintenance of overall health. Whether you like to walk, run, lift weights, or play a sport, I encourage you to get out and enjoy any and all the activity you can!! Keep your body healthy inside and out.
