| 0:00.0 | Hello everyone. Welcome back to Fitbody Happy Joints. My name is Shannon. Sad day. I sad but exciting day. I am recording the final podcast episode in LA before I moved to Austin. It is Wednesday, August 30th and we're driving on |
| 0:17.9 | Friday. I'm going to make the track from LA to Austin. So if it sounds a little |
| 0:22.2 | echo in here it's because I'm sitting in my |
| 0:24.0 | kitchen and there's currently no furniture in my house so let's get to the |
| 0:28.2 | episode because I'm excited about this one it's to be a short but hopefully interesting and |
| 0:33.5 | informative episode. So I want to talk about the phenomenon of increased calorie |
| 0:38.6 | expenditure following a workout or the elevation and metabolism that happens in the following hours or |
| 0:45.6 | following potentially days after you exercise. So I want to break down what this |
| 0:50.4 | means, what the research is saying about the validity of this phenomenon and how it may or may not |
| 0:56.3 | practically affect you in your results. |
| 0:59.2 | So excess post exercise oxygen consumption, excess post exercise oxygen consumption, excess |
| 1:03.8 | post exercise oxygen consumption, which I'll refer to as |

| 1:10.8 | So that increase in metabolism that happens transiently or temporarily after you exercise. |
| 1:18.6 | You may or may not have heard of this being more pronounced after a hit workout or after strength training. |
| 1:24.8 | I'm going to talk about that. But essentially the theory is that your body |
| 1:29.1 | increases the energy that it needs for cellular processes following exercise and that |
| 1:34.6 | requires more oxygen. So this is hypothesized to happen because after you exercise |
| 1:40.1 | your body needs more energy to repair muscle tissue to clear lactate and to |
| 1:46.5 | replenish glucose stores that you may have depleted during your workout. |
| 1:49.7 | So what is the research saying about epoch? Is it real? I want to go over a few studies. I will put all of these studies in the show notes. |
| 1:57.0 | So I want to start with a study that has small sample size. |
