How does alcohol hinder physical performance?

Arsene Wenger is widely regarded as one of the most successful and influential managers in the history of English football. During his tenure as the manager of Arsenal Football Club, Wenger made several significant changes to the team's culture and approach, including his efforts to limit the drinking culture at the club.


Before Arsene arrived at Arsenal in 1996, the club had a reputation for excessive drinking and partying among the squad members. Within two years of arriving, he transformed the team into an elite force that lifted the domestic double in 1998. The removal of the drinking culture in the squad was attributed to how Arsene improved the team, but how does alcohol hinder sporting performance?



Alcohol and Dehydration

One of the most significant ways alcohol can damage sporting performance is by causing dehydration. Alcohol is a diuretic, increasing urine production, which can lead to dehydration. Dehydration has a well-documented range of negative effects on athletic performance, including muscle cramps, fatigue, and impaired cognitive function.


Alcohol and Recovery

Another way in which alcohol can damage sporting performance is by impeding the body's ability to recover after exercise. Exercise causes microscopic tears in the muscle fibres, which the body then repairs during recovery. However, alcohol consumption can delay this process, leading to longer recovery times and reduced performance in subsequent workouts or competitions.


Alcohol and Muscle Growth

Alcohol can also impair muscle growth and development. This is because alcohol consumption can interfere with the production of testosterone, a hormone that plays a key role in muscle growth. Over time, this can reduce muscle mass and strength, significantly impacting athletic performance.


Alcohol and Coordination

Alcohol consumption can also impair coordination and balance, which can be especially dangerous for athletes who engage in high-risk sports. Even moderate alcohol consumption can impair fine motor skills and reaction times, making performing at a high level more difficult.


Alcohol and Mental Health

Finally, it is important to consider the impact that alcohol can have on mental health. Athletes who consume alcohol regularly may be at higher risk of developing anxiety, depression, and other mental health conditions. These conditions can have a significant impact on athletic performance, as well as overall quality of life.




While alcohol may be a popular social lubricant, athletes must be aware of its negative impact on their performance. From dehydration and impaired recovery to reduced muscle growth and impaired coordination, alcohol can significantly impact athletic performance. To perform at their best, athletes should limit their alcohol consumption and prioritize hydration, recovery, and overall physical and mental health.
