Alcohol consumption can adversely impact fitness performance by impairing muscle recovery, coordination, and overall endurance. High alcohol intake can lead to dehydration and disrupt the body’s ability to regulate core temperature during exercise. Additionally, alcohol can hinder the synthesis of protein, essential for muscle repair and growth. This combination of effects can result in decreased stamina, slower reaction times, and an increased risk of injury. Moderating alcohol intake is crucial for maintaining optimal fitness and performance levels.
