If elite male cyclists eat a lot of carbs after a super tough ride, their liver fuel gets completely refilled—and even goes above normal—within 6 hours, but their muscle fuel only comes back about two-thirds of the way after 12 hours.

Carbohydrate intake of 10 g/kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post-exercise recovery in well-trained cyclists.

The study shows that after hard cycling, drinking sugary drinks and eating carb-rich meals helps the liver refill its energy stores quickly—more than before exercise—but muscles only partly refill their energy after 12 hours.

Similar Assertions

If elite male cyclists don't eat carbs after a hard workout that drains their energy stores, their muscle and liver won't refill those energy reserves for at least 12 hours.

If Japanese male endurance athletes eat only 5 grams of carbs per kilo of body weight after tough exercise, their muscles don’t fully refill their energy stores in 24 hours. But if they eat 7 or 10 grams per kilo, their muscles do recover completely in that time.

After a tough leg workout, drinking a sugary sports drink instead of water helps your muscles refill their energy stores faster, so you recover better after six hours.

If Japanese male endurance athletes don't eat enough carbs after tough exercise—like less than 7 grams per kilo of body weight—their muscles refill energy slower in the first half-day, especially between 4 to 12 hours after.

If endurance athletes eat a specific amount of carbs right after a workout—especially a mix of glucose and fructose—they’ll probably refill their muscle energy faster, especially if they’re not eating a lot of carbs overall and need to recover quickly for their next session.
