Does eating carbs before exercise improve 20-km cross-country ski performance?
Updated
Abstract
Ingestion of maltodextrins may improve performance time by 2% in simulated cross-country ski competitions.
- Ten athletes participated in two 20-km time-trials after consuming either maltodextrins or a carbohydrate-free placebo.
- Maltodextrins ingestion did not change blood lactate levels or perceived exertion at the end of the trial.
- Heart rate remained constant across exercises, averaging 177.1 beats per minute.
- Significant differences in performance times were noted between experimental sessions due to varying environmental conditions.
- Athletes receiving maltodextrins showed a greater performance time improvement on the second day compared to the first.
