Alcohol and Athletic Performance
Alcohol can impact your perfomrance in the classroom and on the field. As an athlete, there are a number of ways alcohol impacts your performance:
- Impedes muscle development & recovery. Not only does alcohol cancel out any gains you might get from a workout, it also causes dehydration and depresses the immune system. Have a sports injury? Alcohol will only slow down the healing process for
sports-related injuries by decreasing the secretion of human growth hormone (HGH) by as much as 70%!
- Impacts memory & retention. When you are drinking or your body is still processing alcohol, your ability to learn new information is inhibited. Memories are NOT solidified when you are studying, they are actually solidified when we are sleeping. Consuming 5 or more drinks in one night can affect the brain and body for up to three days later; two consecutive nights can affect the brain and body for up to five days!
- Constricts conditioning. Calories from alcohol are not converted to glycogen (or energy). The body actually treats the body as fat.
- Inhibits nutrition. Alcohol actually inhibits the absorption of vital nutrients and stimulates appetite and consumption of fatty foods.

Effects of Alcohol on Your Body
Alcohol inhibits neurotransmitters causing excitation and increases neurotransmitters that depress nerve responses. Some areas of the brain are more sensitive to the content or level of alcohol in the blood (BAC/BAL) than others. Acute alcohol effects on the mind and body include:
- loss of inhibition and increased
- decrease in ability to problem solve or make decisions
- decrease in sensory input, including sensitivity to pain
- exaggerated emotions
- decreased coordination
- potential memory impairment
- impairment of fine motor skills - for example, being unable, without shaking or jerky movements, to touch tip of the nose with a finger when your eyes are closed
- interference with normal sleep patterns and subsequent input of information into long-term memory
- decrease in body temperature, breathing, and heart rates
- increased blood to skin causing sweating and flushing
- increased blood to stomach and intestines
- decreased blood to muscles

What is BAC?
BAC stands for Blood Alcohol Content, and is the number of milligrams of alcohol per milliliter in your bloodstream. In Pennsylvania, the legal definition of drunkenness is a BAC of 0.08.
If you are a 120-lb. woman who drinks four drinks in one hour, your BAC will be 0.17. If you are a 160-lb. man who consumes five drinks in one hour, your BAC will be 0.14. Of 100 people with a BAC greater than 0.4, statistics show that one will die.
Most people think that if a few drinks make them feel good, then a lot of drinks will make them feel even better. But that’s not true. This is what we call the biphasic (or two-part) effect of alcohol. Here is what happens.
People tend to feel better as their blood alcohol concentration (BAC) rises to about a level of .05/.06. That’s the first phase or part of the process. If someone drinks more and their BAC rises above .055, the negative effects of drinking increase and the consequences more severe. That’s the second phase or part of the process. So, it’s clearly smart to limit alcohol use to remain in the first phase and avoid progression into the second phase.
The first image below provides a visual of the cultural myth of "more is better" and the second provides a demonstration of the biphasic effect of alcohol.

How much alcohol is in one drink?
Because different drinks contain varying amounts of pure alcohol, you should be aware of the proportion of alcohol in everything you drink. A 12-ounce beer (5% alcohol by volume) has the same amount of alcohol as a 1.5 ounce shot of liquor (40% alcohol) or a 5-ounce glass of wine (13% alcohol).
However, we know that many students do not consume alcohol in a standard size glass. Many students underestimate how much alcohol they are consuming because they are consuming alcohol in red cups (like the one we see below). Check out the red cup image below to see just how much one serving of beer, wine and liquor looks like!

Is it okay to drink while on medication?
No, taken before or while drinking, many medications will multiply the effects of alcohol on your body. Aspirin and other drugs prevent the enzyme alcohol dehydrogenase (found in the stomach and liver) from breaking down alcohol, thus slowing the liver's ability to decrease BAC. In other words, alcohol will accumulate in your blood faster and have longer lasting effects. Women on birth control pills will process alcohol slower than other women, because the hormones in the pill and alcohol both rely on the liver for processing.

What are the long term effects of heavy drinking?
There are many serious health complications that can arise from excessive drinking. Someone may develop neurological problems, including impaired motor skills, deterioration of vision, seizures, and permanent brain damage. Long-term heavy drinking will also affect the heart, causing shortness of breath, enlarged heart and abnormal heart rhythm. Someone who has been a long-time heavy drinkers will also be more likely to develop mouth and throat cancer, and also to have high blood pressure, putting them at greater risk for stroke and heart attack. Since alcohol is metabolized by the liver, someone is also at greater risk for alcoholic fatty liver and cirrhosis of the liver. We also know that the use of alcohol is clearly linked to an increased risk of developing breast cancer. This risk increases with the amount of alcohol consumed. Excessive alcohol use is also known to increase the risk of developing several other types of cancer.

Increasing my tolerance is a good thing and blacking out is normal, right?
Having a higher tolerance is a red flag for abusive alcohol use. Higher tolerance means you can ingest more alcohol without showing signs of intoxication. If you drink frequently, your body will become accustomed to the effects of alcohol and you will not feel as drunk, but your BAC continues to rise. Increasing your tolerance will lead you to drink more to achieve the same buzz, leading to greater liver damage, increased risk for alcoholism, and other health complications. Someone who has an increasing tolerance is displaying one sign of problem alcohol use, and it is a cause for concern, not celebration.
Another red flag for concern is blacking out. Blacking out is NOT a normal response to alcohol. It is also NOT the same as passing out. Someone who has blacked out can talk, walk, dance, drive, have sex...because they are still conscious but are not forming any memory about what is happening. Memories are not encoded in their short-term memory, and they may experience partial or total amnesia about events that occurred while they were intoxicated. If someone often reports blacking out as a result of their alcohol use, this is a reason to express concern and seek support.

How can I cure a hangover?
Waking up after a night of drinking is never fun. As part of a hangover, you are likely to experience a headache, body aches, fatigue, heartburn, nausea, and dehydration. Nothing can truly cure a hangover except time (which will vary according to gender, size, weight, tolerance, medications taken, food consumption, dehydration, and rate of alcohol consumption).
However, you can lessen the symptoms by drinking lots of water to combat the dehydration caused by alcohol. Be particularly careful taking any medications. Like alcohol, aspirin can irritate the lining of the stomach, increasing your chances of developing stomach ulcers. Acetaminophen (e.g., Tylenol) is metabolized by the liver, and when combined with alcohol, can cause liver damage. Thus, to avoid further damage to your body, resist taking medication for a hangover.
To avoid suffering a hangover you should consider modifying your drinking habits. Not only should you drink less, be sure to eat while drinking, alternate alcoholic drinks with soda or water, keep track of your use, and make a plan that you share with trusted friends.

Known as alcohol poisoning or alcohol overdose, it can lead to death because too much alcohol is in the blood. Most often this is caused by rapid ingestion of alcohol from chugging, funneling, drinking games or doing shots, and consuming drinks with a high percentage of alcohol. Many of these behaviors that can lead to alcohol-related emergencies happen through pre-gaming actiivities. Even if a person passes out, the blood alcohol content (BAC) can continue to rise because alcohol continues to be absorbed from the intestinal tract.
- Passing in and out of consciousness
- Passed out or unconscious
- Reduced heart rate
- Used other drugs with alcohol
- Vomiting uncontrollably, or vomiting while sleeping or while passed out
- Cold, clammy skin
- Bluish-colored nail bed or skin
- Breathing slowly or with irregularity (less than 8 breaths per minute), or has stopped breathing entirely
- A head injury
It is important to understand that JUST ONE of these symptoms is cause for concern. MORE THAN ONE of these symptoms absolutely constitutes an alcohol emergency. It is important that you do not leave your friend alone, that you call for help (610-519-4444), and that you place them in a position where they will not choke on their vomit. Check out the image below for the Bacchus Maneuver that shows how you should position your drunk friend.

Helping a Drunk Friend
What you do to help depends on the state of your friend. Your friend doesn't have to be passed out or throwing up to need your help. Other signs for concern:
- inability to maintain balance or eye contact
- slurred speech
- shortness of breath
- abnormal body temperature (either too hot or too cold)
If you observe any of these symptoms in your friend, but you're not sure whether to get medical help, err on the side of caution and call VEMS 610.519.4444 or 911 (if you are off campus). If you don't believe it's necessary to seek medical attention, here's what you should do:
- Stop the person from drinking alcohol.
- Find a quiet place for the person to sit and relax (walking around is not the best idea if the person has lost coordination).
- Offer water, but remember that nothing except time can help a person "sober up."
- If your friend wants to lie down, make sure he/she lies on their side and place something behind their back to prevent them from rolling over.
- Monitor your friend's breathing while he/she sleeps to make sure it is not abnormally shallow or slow (less than 8 breaths per minute is considered shallow or slow).
Three General Rules:
- Don't leave your friend alone, even if the person is conscious. Watch for signs of alcohol poisoning.
- Don't assume that they will make it home safely. The full effect of the alcohol may not have hit yet. If they start to vomit, have lost motor coordination, or is no longer coherent, it is necessary to seek medical attention.
- Don't assume an unconscious person is sleeping. If someone cannot be aroused, it is a sign of alcohol poisoning not of deep sleep!
How can you help?
If you observe any ONE of the above, call VEMS 610.519.4444 or 911 (if you are off campus) immediately. Continue efforts to wake your friend, make sure they are lying on their side to prevent choking on vomit, and closely monitor breathing.
Check out the image below to see how you should position your drunk friend in three simple steps.

How to Reduce Your Risk While Drinking
- Set limits. One way to make sure you do not drink to excess is to decide how many drinks your body can safely handle and do not exceed this limit during the course of the night. Unfortunately, it is not always easy to keep track, especially if you have already pre-gamed or when playing drinking games. Such games may provide entertainment and a chance to feel included in a social group, but they contribute to excessive drinking. Chugging alcohol will delay awareness of how much alcohol is in your body because of the time it takes to raise your BAC.
- Eat a meal before you drink. Food will slow the entrance of alcohol into your bloodstream by preventing it from entering your small intestine which absorbs alcohol faster than the stomach. High protein foods, like cheese, are best at slowing down the effects of alcohol, and thus help prevent a hangover.
- Steer clear of carbonation and shots. The carbon dioxide of carbonated drinks, like beer and soda, increases the pressure in your stomach, forcing alcohol out through the lining of your stomach into the bloodstream. The high concentration of alcohol in shots also means that your BAC will increase rapidly.
- Alternate with non-alcoholic beverages. Not only will this slow your consumption of alcohol, but it will also counter the dehydrating effects of alcohol.
- Don't combine alcohol with other drugs. Alcohol's effects are heightened by medicines that depress the central nervous system, such as antihistamines, antidepressants, anti-anxiety drugs, and some painkillers. Other drugs have harmful interactions with alcohol as well, so it is best to consult a physician before drinking while on medication. The combination of illegal drugs and alcohol can also have adverse effects. To read more about alcohol's interaction with over-the-counter and prescription medications, click here.
- Don't drink if you're suffering fatigue or feeling depressed. Exhaustion magnifies the effect of alcohol on the body, and alcohol exacerbates negative mood. For someone who is struggling emotionally, alcohol is an ineffective coping strategy.
