To assume you need to feed, because the beast within is calling for food, is a myth. HERE ARE THE GROWLING FACTS: - It comes from the intestines, caused by moving air and muscle contraction of the intestinal wall. - It is commonly heard on an empty stomach, because food isn't present to muffle the sound. Also with food present, the body focuses on digestion instead of shuffling air back and forth. - It can occur on a full stomach, and can spark 2 hours after a meal. - Low blood sugar increases its activity. - And swallowing too much air can also spur its occurrence.

And the only reason we've associated it with hunger is because it's frequently heard on an empty stomach - when it's almost breakfast, lunch, and dinner time.

This post is going to be pretty technical - it was the assignment I did for my Science of Exercise course on Coursera. Since I received my completion certificate last week, I thought, why not share my paper with you guys. It's now less science-y and more comprehensible with some editing. So without further ado, let's get to it! WHAT IS THE FICK EQUATION? The Fick Equation calculates the maximum volume of oxygen (VO2) an individual uses during a single bout of exercise. It derives on the formula VO2 = Q x (A-V)O2. OVERLOAD PRINCIPLE AND ADAPTATIONS To understand training adaptations is to first understand the Overload Principle. The Overload Principle is the inducing of stress upon the body - greater than before - in order to increase fitness and performance. It is the notion behind training adaptations in the body. When a sedentary individual begins a training program, their body begins adapting (through overload) in the cardiovascular system, directly affecting ca
