Tie up those shoe laces.

I found another reason why you should tie up your laces and exercise. More and more studies are discovering a relationship between physical activity and satiety. To get a better grasp, satiety can be described as the “feeling” of fullness, and is not wholly understood because of the variety of factors that affect it. In fact, the discovery of hormones that control satiety is only very recent and poses a possible theory as to why our appetite’s change under different conditions. Another study was just released concluding exercise over a long period of time demonstrates a stronger control over appetite. Pretty cool eh? Researchers suspect that exercise’s power to regulate hormones play a major role. The only catch is that you have to repetitively work and get your blood pumping which requires a change in lifestyle.

I know you’re probably thinking the impossible, but it is completely do-able. How much control do you have? All throughout high school I sat in front of my computer playing MMORPGs. The first time I attempted to jog, I couldn’t even make it once around the track without huffing and puffing.  I’ve changed my lifestyle habits and never felt better. I can’t say it wasn’t easy though – blood, sweat and tears my friends.

Last spring, I had a wonderful opportunity to participate in a lab based nutritional science capstone. Best of all, I got to spend my semester exercising… can’t get much better than that right? Well… except for pricking my fingers 15-20 times a session to take blood samples, haha.. Our mission was to figure out the relationship between exercise, satiety and blood glucose. Although our data was mostly inconclusive due to the time constraints, lack of technology, and sample size, we still saw some interesting trends. As predicted, the five of us observed an enhanced response to blood glucose absorption. The men (n=3) in our study saw an initial  decrease in satiety (hungry) after exercising while the women (n=2) found  an initial increase in satiety (not hungry). It’s pretty cool to see similar findings coming to light in mainstream media. Make sure you thank your science geek friends for their hard work the next time you see them. 😉
