Energy balance
There is no difference in performance time for a subsequent ride after consuming different preexercise meals.
This suggests that athletes may not need to focus on the glycemic index of preexercise meals for performance outcomes.
StrongSupportsmedium confidence
There was no difference in time to complete the subsequent performance ride (946 +/- 23, 954 +/- 35, and 970 +/- 26 s for HGI, LGI, and Con trials, respectively).
Why this rating
Based on study design from abstract.
