Alcohol can negatively impact fitness performance by impairing muscle recovery, reducing strength, and affecting overall endurance. Consuming alcohol can lead to dehydration, which is crucial for optimal performance. It also interferes with the body’s ability to synthesize protein, thus hindering muscle repair. Additionally, alcohol can disrupt sleep patterns, diminishing recovery time, and can affect coordination and balance, increasing the risk of injury during workouts. Therefore, moderating alcohol intake is important for those looking to enhance their fitness outcomes.
