1. portability First of all, because of portability, bananas are easy to carry, and as a supplement after fitness, they are a high-quality source of carbon water; If you use other things to supplement carbohydrates, you will bring much less bananas.
2. The second point of potassium supplement is potassium supplement. We sweat a lot during training. Sweating means losing a certain amount of electrolyte, which contains potassium. Eating bananas can just supplement potassium, and bananas are a good source of potassium.
3. Prevent muscle loss. You may think that the above two points are not well understood. Then this third point is the most important principle. It is complicated and involves two hormones, insulin and cortisol. Let's talk about the principle in detail: after strength training, especially after strength training like muscle building.
First of all, we should know that strength training mainly consumes glycogen in our body. After training, our body will lack some glycogen. If we don't supplement it in time, our hormones will respond accordingly, that is, our cortisol will rise, which is an anti-stress hormone. The rise of cortisol will catabolize our muscles to some extent. Our muscle training is to grow muscles, and we can't let them lose after training. Therefore, we should reduce this cortisol immediately.
It happens that cortisol has an anti-hormone called insulin. How to raise insulin? You need to eat carbohydrates, and the type of this carbohydrate is preferably fasting carbohydrates, rice, steamed bread, noodles or fruit. Supplementing glycogen makes blood sugar rise, while insulin rises to produce anti-cortisol. After cortisol drops, our body will not catabolize muscles, and accordingly it will become anabolic.
To sum up the two points mentioned above, bananas are fast carbohydrates and easy to carry. Of course, I suggest you add a banana after muscle training to put your body in a state of anabolism, and then drink some protein powder accordingly. At this time, glycogen is loaded with amino acids (amino acids constitute the main substance in protein) to better repair your torn muscles and help you recover and grow muscles. This will get twice the result with half the effort. It may be possible if you add it after training.
To sum up, the above are all the principles why bananas should be supplemented after fitness. First, it is because of portability, but because of electrolyte replenishment. Third, it is to prevent muscle loss. I hope it helps you. Xiao Fang loves to lift iron! Share your fitness knowledge every day to help you get in shape!
