- Brief Summary
This study aims to investigate the effect of acute carbohydrate intake during a crosstraining session on exercise-induced muscle damage and the recovery of crosstraining athletes.
- Detailed Description
Carbohydrate intake during exercise could decrease the subjective perceived exertion and promote recovery during high-intensity and intermittent exercises such as crosstraining. Nevertheless, despite extensive research on carbohydrate ingestion during exercise across different sports disciplines, its effects have not been investigated in crosstraining sessions.
23 male trained crosstraining athletes will ingest carbohydrates (60g of maltodextrin + fructose, 2:1 ratio) or placebo during a one-and-a-half-hour crosstraining session. The session will consist of a warm-up, a weightlifting part, a strength part, a WOD, and an AMRAP. The rating of perceived exertion (RPE) will be assessed using the validated Borg scale at the beginning of the session, after each part of the training, and at the end of the session. DOMS will be assessed using a visual analog scale at 24 and 48 hours after the crosstraining session.
