An athlete’s resting glucose level is an under-appreciated biomarker.
It can reveal a lot about what’s going on inside an athlete’s body when trends are logged and interrogated.
We all know different food fuels out workouts in different ways. We know exercise requires high levels of sugar to give us energy and so high carb diets are recommended and protein helps muscle recovery. But how much of what? What timing works for us better?Do we supplement with sugar? If so, what type?
We all know the feeling of a blood sugar drop. That moment we know the fuel we chose isn’t sustaining us, and it sucks.
Our blood sugar levels influence our carbohydrate availability for sustained energy during exercise, as well as the subsequent recovery of our muscle glycogen reserves, and both play a pivotal role in our performance in our sport.
Monitoring blood sugar trends will allow us to establish the right carbohydrate content for our unique personal biology (amount and type) and the best nutrient timing to our bodies’ ability to handle glucose. And this will differ from person to person.
If our body is forced to run from our supplies of fat rather than blood sugar, we will be slower and have less energy and won’t be able to exercise as intensely. As a result, our coordination, dexterity, concentration and reactions could be adversely affected too.
Importantly, muscle glycogen, the predominant form of stored glucose in the body, and blood glucose are the main energy substrates for muscle contraction during exercise. Therefore, it is essential that as athletes, we monitor our diet to maintain and increase muscle glycogen deposits, since they are a major limiting factor of prolonged exercise performance.
It is also important for athletes to replenish glycogen stores after exercise, with a view to providing enough energy for the next training session or competition and enabling glycogen synthesis to be enhanced through the addition of protein.
However, each athlete must work to their bodies ability to convert glucose into useful forms otherwise higher levels of fasting glucose will be experienced that over time can lead to life-threatening conditions like diabetes.
