Carbohydrate ingestion improves exercise performance and capacity. However, not all carbohydrates are created equally.
I’ve just published a new study in which we compare different carbohydrate-rich sport drinks.
Here’s the main result of the study:
This picture shows you how much carbohydrates from your sports drink you actually burn. It’s much higher if you ingest a combination of glucose+fructose or glucose+sucrose compared to the same amount of carbohydrates provided as only glucose.
I’ve broken down the study in more details in the video below.
Now if you want to know even more, check out the advanced video. In this video I explain how we measure exogenous carbohydrate oxidation rates, and why the figure shown above is not as straightforward as it might seem.
We have previously studied the impact of same fructose co-ingestion tactic post-exercise muscle and liver glycogen recovery. Check that article out here.
