Kayaking requires high energy expenditure and optimal metabolic adaptation for performance and recovery. While research on other sports exists, the effects of chocolate milk on kayakers' recovery remain unexplored. Intensive kayaking induces physical stress, necessitating precise energy balance monitoring. This study evaluates metabolic and inflammatory markers, including glucose, glycogen, insulin, creatine kinase (CK), interleukin-6 (IL-6), ghrelin, leptin, peptide YY, peripheral blood morphology, and blood gas parameters to assess fatigue and recovery. Chocolate milk, with its ideal carbohydrate-to-protein ratio, supports glycogen replenishment, muscle repair, hydration, and oxidative stress reduction. Studies suggest it may outperform commercial sports drinks in endurance recovery by limiting muscle damage, inflammation, and improving acid-base balance. Findings will reveal whether chocolate milk enhances energy recovery, reduces muscle damage, and mitigates inflammation, contributing to endurance sports nutrition strategies
