The Claim
Carbohydrate intake following a 14-hour fast results in a minor improvement in anaerobic performance and a measurable improvement in muscular endurance among trained men.
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 a 14-hour fast, consuming carbohydrates slightly improves short bursts of high-intensity effort and clearly improves the ability to sustain muscular effort over time in trained men.
See the scientific wording
Carbohydrate intake after a 14-hour fast has a minor effect on anaerobic performance but improves muscular endurance in trained men, indicating that its benefits may be specific to sustained effort rather than explosive power.
After a long fast, muscle fuel runs low. Eating carbs restores energy stores, letting muscles keep contracting for longer without tiring, but doesn't make quick bursts stronger because those rely on other systems that aren't boosted by carbs alone.
What the research says
1 studyAfter fasting overnight, eating carbs didn’t help men sprint faster but did let them do more push-ups and squats before getting tired. So carbs help with lasting effort, not quick bursts.
