Alcohol can negatively impact athletic performance in several ways. While moderate consumption may have some benefits, excessive alcohol intake can lead to dehydration, impaired muscle recovery, and decreased coordination. It hampers the body's ability to effectively synthesize protein and recover from workouts, potentially leading to muscle loss. Furthermore, alcohol can interfere with sleep quality, which is critical for performance and recovery. High-calorie alcoholic beverages can also contribute to weight gain, making it essential for athletes to consume alcohol mindfully to maintain optimal performance levels.
