Why carbs after a bike ride make your muscles stronger
Glycogen supercompensation in skeletal muscle after cycling or running followed by a high carbohydrate intake the following days: a systematic review and meta-analysis

Surprising Findings
Higher baseline glycogen levels led to LESS supercompensation after cycling.
Common belief: if you start with more energy, you’ll store even more. But this study shows muscles have a ceiling—starting full limits how much extra you can store, even with massive carb intake.
Practical Takeaways
If you’re training for a cycling event, do a hard ride to deplete glycogen, then eat 70–80% of your calories from carbs for 3–5 days to maximize muscle fuel storage.

Increased carbohydrate intake enhances intramuscular glycogen storage, thereby improving resistance training performance and volume capacity.
After biking really hard and then eating a lot of carbs for a few days, your muscles store way more energy than they do after running hard and eating the same way.
When you eat a higher percentage of your calories from carbs (like 80% vs 60%), your muscles store more energy after a hard bike ride—even if you’re eating the same total amount of carbs.
The more you deplete your muscle energy stores during a hard bike ride, the more your muscles can overfill with energy afterward when you eat carbs.
If your muscles already have a lot of stored energy before you start exercising, they don’t store as much extra energy afterward—even if you eat lots of carbs.
