The Claim
In well-trained cyclists, consuming a high-glycemic-index carbohydrate diet for 24 hours after exhaustive exercise results in a greater increase in muscle glycogen storage (106 ± 11.7 mmol/kg wet weight) compared to a low-glycemic-index diet (71.5 ± 6.5 mmol/kg wet weight).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After intense cycling, eating carbohydrates that digest quickly leads to a larger increase in muscle glycogen stores than eating carbohydrates that digest slowly, based on measured levels in muscle tissue.
See the scientific wording
In well-trained cyclists, consuming a high-glycemic-index carbohydrate diet for 24 hours after exhaustive exercise results in a greater increase in muscle glycogen storage (106 ± 11.7 mmol/kg wet weight) compared to a low-glycemic-index diet (71.5 ± 6.5 mmol/kg wet weight), suggesting that post-exercise glycogen resynthesis is more efficient with rapidly digested carbohydrates under these conditions.
After intense exercise, eating carbs that quickly raise blood sugar causes a strong insulin surge. Insulin tells muscle cells to open their glucose doors, pulling in more sugar. The muscle cells then use that sugar to rebuild their energy stores as glycogen faster than when blood sugar rises slowly.
What the research says
1 studyAfter a super hard bike ride, eating carbs that spike your blood sugar fast (like white bread or sports drinks) fills up your muscles’ energy stores more than eating carbs that spike it slowly (like beans or whole grains), even if you eat the same total amount of carbs.
