If you have already wondered whether it is possible to drink coffee before training, then you probably realized that the topic is very controversial. Some people say that the drink is harmful and that it is not compatible with sports. Others insist that coffee before training in the gym is not only possible, but even necessary. We suggest not to get lost in guesswork, but to understand this topic based solely on facts.
In this article we will tell you how the popular aromatic drink affects the body and the effectiveness of exercise and whether it can really be used for weight loss. As a result of reading the material, you will be able to draw your own conclusions about the benefits and harms of coffee.
Coffee is not as scary as they say...
Even one sip of aromatic drink affects our body. The components contained in coffee (there are more than 100 of them in total) quickly penetrate the blood and affect many processes. So, what do science and medicine say about the effect of this drink on the body?
- It is a well-known fact that drinking coffee causes your blood pressure to rise slightly. If we are talking about one cup, then the pulse slows down a little, but after the second cup the heart rate speeds up.
- Coffee stimulates the production of hydrochloric acid in the stomach, so drinking a cup after a meal is not so bad, but we do not recommend doing this on an empty stomach - it can cause irritation of the mucous membrane.
- There is also some diuretic effect, which many consider too weak and unworthy of attention, although this depends solely on the individual characteristics of the body.
- Caffeine invigorates and promotes the release of adrenaline, which, in turn, helps to “open” the lungs, making breathing easier, and causes the liver to release glycogen into the blood, providing the body with additional energy. It has been proven that coffee stimulates the production of dopamine - the “happiness hormone”. If there is an excess, the opposite effect is observed: sleep disturbance, anxiety, irritability.
Many people equate coffee with a drug, and there is some truth in this. A person not only psychologically gets used to starting the work day with an invigorating drink or drinking coffee before a workout, his body also physically becomes dependent. Abruptly quitting caffeine after a long period of continuous use can lead to headaches, fatigue, depressed mood and inability to concentrate.
Harm of coffee drink
After studying this section, you will finally decide for yourself whether you can drink coffee before training or not. The fact is that the answer to this question is very individual. Some people cannot tolerate the components of the drink or it is contraindicated for their health. Also, negative factors are highly correlated with the amount of caffeine consumed. We urge you to soberly evaluate the information, and emphasize that there are no strict contraindications for drinking coffee before training.
So, what happens if you abuse or drink a coffee drink before exercise if you have personal contraindications?
- It has little effect on the process of calcium leaching. True, so that you understand the scale, a plate of semolina porridge, meat, sweet soda, as well as spicy or pickled foods are more harmful;
- Caffeine, alas, is addictive, with all the delights of withdrawal syndrome (if you decide to reduce the daily dosage);
- The drink is prohibited for cardiovascular diseases; it actually increases the load on the heart and increases blood pressure;
- If you drink a cup of aromatic dope on an empty stomach, you can cause indigestion. The components of its composition strongly irritate the organ mucosa;
- Coffee is a diuretic, so it causes dehydration. Don't forget to drink water during your workout;
- Caffeine is a drug. Yes, but keep in mind that it is found in many other products that you consume regularly: tea, chocolate, energy drinks, cocoa, Coca-Cola, and also in some nuts.
The benefits and harms of coffee before training
So, we briefly outlined the general aspects of what you should know about the effects of coffee on the body above. Now let's move directly to the question: can athletes drink coffee before training? The answer to this question is not clear - a flavored drink can bring both benefit and harm to the athlete. It all depends on the individual characteristics of the body and the amount of coffee drunk. Let's start with the positive aspects and the benefits that an athlete can get from a cup of an invigorating drink.
Beneficial properties of coffee
The list of beneficial properties endowed with this beloved drink is quite impressive. Below are its main advantages that athletes can wisely use to slightly improve their athletic performance.
Increased stamina
Caffeine is the most popular among mild stimulants and for good reason. Athletes training specialists in the States have proven that strength increases by about 10% if the body is given a caffeine boost before training.
Even at the highest level of sports, coffee is used by athletes to enhance performance. Therefore, the Anti-Doping Committee is considering adding caffeine-containing drugs to the list of prohibited substances. Manufacturers of sports drinks and snacks do not even hide the fact that a third of all products contain caffeine. And the British company TrueStart Coffee recently launched a special luxury freeze-dried coffee specifically for athletes who want to optimize performance. By the way, this brand was founded by triathlete spouses.
Relief of muscle pain
Drinking coffee before a workout may not completely eliminate subsequent muscle pain, also known as DOMS, but it will noticeably reduce the pain.
In one study, subjects were given caffeine at 5 mg/kg body weight (equivalent to about 2.5 cups of espresso) and then subjected to a grueling workout. As a result, the pain on days 2-3 after training was approximately half as great.
Improved reaction and alertness
Australian scientists from a medical university concluded that caffeine increases brain activity mainly in the area responsible for attention and short-term memory.
First of all, the stimulating effect of coffee is caused by the ability of caffeine to masquerade as adenosine, known as the fatigue hormone. Adenosine accumulates in the body while you are awake and when it reaches a certain point, the brain decides it is time to sleep. Caffeine binds to certain receptors instead of adenosine and tricks the gray matter into continuing to function in an excited state.
Acceleration of metabolism
Coffee speeds up metabolism by 3-4% at rest and up to 15% during training. At the same time, caffeine enhances the breakdown of fat for energy. To ensure that fats are taken from personal reserves, it is not recommended to drink coffee with cream or milk before training. While fat is being broken down, glucose and glycogen are not used, this allows the necessary level of sugar in the plasma to be maintained, which ensures a feeling of fullness.
Additional source of nutrients
Coffee beans contain about 35% stable solids, which remain unchanged during long-term storage and pass into water after brewing.
Main components of coffee:
- Caffeine – 0.7-3.2%;
- Protein – 9-19%;
- Fats – 9-18%;
- Carbohydrates – 4.2-11.5;
- Organic acids up to 10.5%;
- Microelements (potassium, magnesium, calcium, sodium, manganese);
- Vitamins (PP, B1, B2).
All of the above substances are important for the body and will not become superfluous during exercise. For example, potassium and magnesium activate muscle work and participate in the synthesis of protein and ATP - a universal source of energy for all biochemical processes. Potassium provides electrical potential to nerve cells, regulating muscle contraction. Vitamin PP (niacin) is involved in the metabolism of fats and proteins, tissue respiration, glycogenolysis.
Negative effects of coffee on the body
The negative effect on the body is usually caused by individual intolerance, abuse of the drink or health problems for which it is contraindicated. There are also several negative aspects depending on the properties of the drink itself. So, who and why should not drink coffee before training?
Calcium leaching
After drinking a coffee drink, the acid-base balance shifts towards acids, so calcium reserves are released, which are necessary to neutralize them. One cup of coffee is responsible for the loss of approximately 40 milligrams of calcium. In defense of coffee, I would like to note that the main culprits in calcium removal are carbonated sweet drinks, pickled, spicy and sour foods. The honorable second and third places were shared by semolina porridge and meat products. Therefore, giving up coffee does not mean that the calcium content in the body is not in danger.
Reverse effect and addiction
The effect of coffee is often the opposite. For the first time, after 20-30 minutes of training, you feel a surge of energy, but subsequently, the body, exhausted from heavy exertion, turns out to be even more tired. In addition, like any stimulant, caffeine is addictive. To get the desired effect, you have to increase the “dosage”, which entails a number of negative consequences. For people who often drink this drink, it does not matter how long before a workout they drink coffee, since the desired result will not be achieved, since the body is used to it.
Effect on the heart
Not the most encouraging studies were recently conducted by specialists from the University of Zurich and the Center for Integral Human Physiology. They found that two cups of coffee before exercise limits the ability of the heart muscle to increase blood flow, which reduces the flow of oxygen and nutrients to tissues and organs. The participants had their blood flow measured before and after exercise and then divided into two groups. In the first group, the subjects drank two caffeine-containing tablets (about 2 cups of strong coffee), while in the second they did not drink anything. In a calm state, all subjects had blood flow within normal limits; after the end of the workout, those who took caffeine noted a 25% decrease in blood flow through the heart.
First of all, this study has implications for people suffering from low blood flow. Whether it is necessary to drink coffee before training is also worth considering for those who live and, accordingly, train in mountainous areas.
Caffeine is a diuretic
Coffee is not the strongest, but it is still a diuretic, which means it is able to “expel” water from the body. In addition to this, a significant amount of fluid is lost during increased physical activity. All together can lead to varying degrees of dehydration, which puts stress on the kidneys. Therefore, if you decide to drink coffee before training, you should also stock up on water.
If this does not happen all the time, there is nothing particularly to be afraid of, but when even minimal dehydration becomes regular, the water-salt balance is disrupted, and the risk of developing renal failure increases.
Benefits of caffeine before exercise
First, if you haven't added sugar or cream to your cup of coffee, it contains zero calories. In addition, coffee before a workout for weight loss helps speed up metabolism and burn fat, which will be appreciated by everyone who wants to get rid of extra pounds.
If you're facing an endurance workout, a dose of caffeine in any convenient form will help you get through it, according to scientists at the Australian Institute of Team Sports. Some coaches even suggest abstaining from caffeine for a week before an important race, and drinking a cup of espresso on the day of the endurance competition to give the caffeine-weaned body an additional boost of energy.
A moderate dose of this stimulant can even increase your performance. By the way, it was because of this that the International Olympic Committee banned caffeine before performances, in any form: no lattes or chocolates.
Secondly, caffeine stimulates your nervous system and improves concentration before exercise. Figuratively speaking, a cup of coffee before going to the gym can be considered as part of the warm-up, which will facilitate your adaptation to work.
It is believed that caffeine can relieve pain and muscle fatigue after intense strength training. According to another theory, coffee interferes with muscle recovery after exercise, and therefore is not recommended for consumption within the first two hours after visiting the gym. However, both theories have not been confirmed.
One cup of coffee can relieve fatigue during aerobic exercise, and two cups of espresso, which contain a total of 250 mg of caffeine, will help you improve your performance. There are many examples of positive effects in sports such as running, swimming, cycling.
How much coffee do you need to consume to get the effect?
It all depends on your weight. It is recommended to adhere to the following calculation: 0.5-1.4 mg of caffeine per 1 kilogram of weight. For example, a cup of espresso contains 100 mg of caffeine, an American - about 80.
If everything is so rosy, and a cup of coffee before a workout can make you practically a champion, why is there so much controversy around caffeine? What's the catch?
Coffee and caffeine
Caffeine is an alkaloid, a compound of plant origin, with pronounced physiological activity. Contained in coffee seeds, tea leaves, cocoa fruits, cola fruits and some other plants. The substance is synthesized by them to protect against insects, as well as to encourage pollinators.
In everyday life, people often perceive coffee and caffeine as a single whole, but this approach is not entirely correct. Let's pay attention to the plate, which clearly shows the alkaloid content in various foods and drinks. Perhaps a cup of coffee before training will not be the only source of an invigorating substance.

Coffee before exercise for weight loss
Coffee really helps you lose weight when combined with exercise, this is not a myth. As already mentioned, the drink increases endurance, reduces appetite, helps you do your best in classes and speeds up metabolism. We are talking about natural coffee before a morning workout without sugar and especially high-calorie cream. If the body receives a portion of glucose, it will not need to burn fat to get energy and deposits will be intact.
Harvard scientists decided to find out which pre-workout coffee is more suitable for burning fat: black or green. As a result, the “green” group lost an average of 5.5 kg over 3 months, and the “black” group lost up to 2 kg.
The weight loss effect of coffee can be enhanced if the product is used only as an additional factor, and the main emphasis is placed on proper nutrition and exercise.
Benefits of drinking coffee before running
- Increased efficiency
- Increased concentration
- Improved perception of effort
- Accelerating the fat burning process
Caffeinated coffee can be a useful addition to your pre-tension diet. Thus, according to the results of a study conducted by a group of scientists from the UK, Croatia and the USA and published in The Conversation in April 2021, caffeine can increase the effectiveness of sports activities . Despite the fact that caffeine is chemically very similar to adenosine (a substance that slows down the brain and causes a feeling of extreme fatigue), it acts just the opposite, due to which fatigue is dulled and the perception of effort is changed. That is, after caffeine enters the body, a person can feel a surge of vigor and appreciate a workout that previously seemed very difficult, easier and doable.
Also, in a J Sci Med Sport study of 30 athletes, it was found that runners who took caffeine before a race improved their standard performance by an average of 1% . More clearly: if previously an athlete ran 5 km in 20 minutes, then after caffeine he covered the same distance 12-13 seconds faster.
In addition, coffee stimulates brain function and increases concentration . In this case, the runner is more sensitive to changes in his own sensations, and also focuses on the result of the movement, and not on the process itself, which increases the overall effectiveness and safety of the training.
For long-distance runners, an important benefit of caffeinated coffee is its ability to activate fat burning for energy , thereby preserving glycogen stores.
What to replace coffee with?
Lovers of coffee taste and aroma can try replacing the classic drink with decaffeine. Caffeine is removed from green coffee beans, but this has little effect on the aroma and taste of the drink. It is believed that decaf is practically no different from classic coffee, and therefore is an excellent alternative for fans.
If coffee as a drink is not interesting, but its stimulating effect is what is needed, then a cup of strong tea can be a substitute for coffee. More radical replacement options include caffeine tablets, energy drinks and pre-workout mixtures. There is even special coffee fortified with protein.
When and how much coffee can an athlete drink?
The benefits and harm that a drink can bring are more or less clear. It remains to find the answer to two important questions, which will determine whether the drink will help or cause a negative reaction in the body.
Recommended Dosages
So, the first question is, how much coffee can an athlete drink without it negatively affecting him? The principle applies here: more does not always mean better. For pre-workout coffee to work as a stimulant and have only a positive effect on the body, it must be consumed in reasonable quantities.
Of course, in each individual case, the number of cups drunk is highly individual, however, there are several basic recommendations:
- If a positive effect during training is needed, then the average dose of caffeine for athletes should be 150-500 mg (3-5 mg/kg body weight). This is approximately 1-2 cups of espresso. A smaller amount of coffee will not have a noticeable effect, and a larger amount may lead to undesirable consequences.
- The maximum daily dose of caffeine for an adult is approximately 1000 mg, and a single dose is 400 mg. Exceeding the maximum permissible doses can cause death. Symptoms of intoxication are as follows: insomnia, anxiety, headaches, nausea, rapid breathing and irregular heart rhythm. In more severe cases, muscle twitching, incoherent speech and thoughts. These reactions often disappear as the substance is eliminated from the body.
- To avoid addiction, you need to take a break for 5-7 days every two weeks. This gap will be enough to clear the receptor cells, which will again be ready to adequately perceive the stimulant and work in the right direction.
