If we spike the level of our blood sugar then we have lots of energy … for a little while, and then we come crashing down. This doesn’t work so well for “endurance” athletes. Simple sugars can do just that, a little bit is okay but too much will quickly raise your blood sugar. If it could stay elevated life would be great, but unfortunately it can’t, and when it comes back down it drops (crashes) well below where it started.
When this happens during athletic activity it is a dual edged sword. Your performance will drop as the blood sugar drops because your body is depending on that energy, and your body will no longer be able to as efficiently convert your muscle glycogen into usable energy … here comes the BONK!!!
The goal is to maintain a consistent blood sugar level without the spikes and crashes, and this is achieved by relying primarily on complex carbohydrates and low sugar levels.
