5 effects of caffeine on sport performance

Most people love coffee, whether because of its taste or just because they can’t start their mornings without one to wake them up, making it one of the world’s most popular beverages. In this article we explain its wide range of benefits, which goes from being full of antioxidants, to having a positive effect on preventing several serious deceases.

What is caffeine and to what does it owe its stimulant effect?

Caffeine is a natural stimulant which can be found in different teas, coffee and cacao plants; its most highlighted benefit is preventing tiredness and helping you to focus and stay alert, thanks to the way it stimulates your brain and nervous system.

After consuming caffeine, just 15 minutes are enough for it to enter your bloodstream and start keeping you awake.

Which foods and beverages contain caffeine?

Coffee is the biggest source of caffeine, followed by some other plant infusions and chocolate, which contains more caffeine when it has higher cocoa content. The caffeine content in your coffee depends on many factors like the type of coffee beans, the roasting, the type of coffee and the serving amount you take.

The approximate amount of caffeine on different beverages goes as following:

  • Brewed coffee: One cup of brewed coffee (236,6 ml) contains about 70–140 mg of caffeine, or about 95 mg on average

  • Espresso: One shot of espresso is generally about 30–50 ml and contains about 63 mg of caffeine. A double shot of espresso therefore contains roughly 125 mg of caffeine.

  • Instant coffee: Usually contains less caffeine than regular coffee, with one cup containing roughly 30–90 mg

  • Decaf coffee: To your surprise, decaf coffee is not entirely caffeine free. It may contain varying amounts of caffeine, ranging from 0–7 mg per cup, with the average cup containing 3 mg.

  • Yerba mate: A cup of this plant infusion drink contains between 65 and 130 mg of caffeine.

  • Energy drinks: The caffeine amount depends on the brand and product, but in general you can count with 50-160mg for 250ml of energy drink.

  • Cocoa beverage and chocolate milk: Due to their cocoa content, 2 to 7mg of caffeine are in them.

Why people like to drink coffee or tea right after waking up?

People drink coffee or tea every morning because the caffeine increases alertness quicker than the body’s naturally produced hormones. Regardless of whether you are a morning person or not, you probably have a morning beverage habit. Coffee fans cannot face the day without a “cup of joe”, while tea drinkers feel out of balance if they don't awaken with a cup of herb, black or green tea.

After taking caffeine, the body produces cortisol, which helps you to ‘feel better’ and to help the body deal with stress and blood pressure. Caffeine also functions by blocking the effects of adenosine, which is a neurotransmitter that relaxes the brain and makes you feel tired. These effects are the best for alertness and for people to start their day.

But not everything is as good as this sounds, getting too much caffeine is linked to adverse effects like anxiety, sleep disruptions, heart palpitations and restlessness. Additionally, having a coffee early in the morning when the body is naturally producing cortisol can result in excess and building resistance to the natural cortisol-induced boost, instead of adding to it.

In conclusion, the best time to have a coffee is two or three hours after waking up, for you to enjoy the boosting benefits without interfering with your normal body functions.

How can taurine boost caffeine’s effect?

Taurine is an amino acid, which is also found in the body in natural form. In addition to caffeine, taurine is often added to energy drinks, although taurine is not a stimulant, but it has a stimulating effect on the brain function. Taurine supports communication between the neurons, protects the nerves and promotes the maintenance of the cell membranes in the body.

According to certain researches, taurine and caffeine perfectly complement each other in a way that they both improve physical and mental performance and therefore it is not a coincidence that they are often used together in energy drinks. Taurine boosts physical performance by helping the flow of glucose to the muscles, thus ensuring primary energy source for operation.

Health benefits of caffeine

Among the most known health benefits of caffeine, you can find the following ones:

Source of antioxidants: Antioxidants are molecules that neutralize the free radicals and protect your body from its harmful effects and oxidative damage. Coffee is rich in powerful antioxidants, and many people get more antioxidants from coffee than from fruits and veggies combined.

Contains essential nutrients: Coffee contains several important nutrients, including riboflavin, pantothenic acid, manganese, potassium, magnesium and niacin.

  • Riboflavin (vitamin B2): 11% of the Reference Daily Intake (RDI).

  • Pantothenic acid (vitamin B5): 6% of the RDI.

  • Manganese and potassium: 3% of the RDI.

  • Magnesium and niacin (vitamin B3): 2% of the RDI.

Caffeine may boost metabolism: Several studies show that caffeine can increase fat burning and boost your metabolic rate. If you're primarily interested in coffee for the sake of fat loss, it may be best to cycle your coffee drinking habits to prevent a buildup of tolerance. Perhaps cycles of two weeks on, two weeks off is best.

Protects the liver: People who drink coffee have a much lower risk of cirrhosis, which can be the consequence of many diseases that affect the liver. Coffee can also help you for already existing liver conditions, as research shows that moderate amounts (between 1 and 3 cups a day), may slow down conditions such as fibrosis, hepatitis B and C and other fatty liver deceases.THE EFFECTS OF CAFFEINE ON SPORT PERFORMANCE

The effects of caffeine on sport performance

1. Improves physical performance

Caffeine has been shown to stimulate fat loss, help with weight management, and enhance exercise. If you’re trying to optimize your body composition, caffeine is one of your allies.

The fat in your body is known as adipose tissue, which caffeine helps to break down in a process called lipolysis. This way, the fatty acids are freed from its storage form and will be ready to be used as energy, meaning it will be burned being used by your body functions.

2. Caffeine increases muscle oxygen saturation

Ingestion of significant amounts of caffeine, meaning 3 mg/kg, is linked to potentially improving peak aerobic performance and increasing peak pulmonary ventilation. In addition, caffeine has effects on the oxygen saturation in your muscle during high intensity exercises.

3. Helps in fat loss by increasing body temperature

Thermogenic fat burners contain stimulants like caffeine, which increase your body temperature with a few decimal degrees, which requires more energy from your body, so it will burn more calories. This way you can support your weight loss practically without physical exercise, but of course, you'll also need a workout regimen, as otherwise this effect won't be enough.

4. Post exercise caffeine helps muscles refuel

The muscles’ main source of energy during your workouts is called Glycogen, and new research has shown it is replenished faster when athletes ingest both carbohydrate and caffeine after performing intense exercise. With athletes who ingested caffeine with carbohydrate had 66 percent more glycogen in their muscles four hours after finishing intense, glycogen-depleting exercise, compared to when they consumed carbohydrate alone; meaning they were showing higher energy in their muscles to be used for recovery and tissue reconstruction.

5. Caffeine improves focus and energy

Caffeine is really “nature’s stimulant”. It easily gets into the brain, and affects many kinds of brain cells in a positive way.  Caffeine can increase mental focus and concentration. Studies also show that coffee improves various aspects of brain function, including memory, mood, vigilance, energy levels, reaction times and general mental function.


How to supplement with caffeine

In average, people should take 200–400 mg of caffeine anhydrous, 60 minutes before a race or event, can help maximize performance benefits. This dose is based on body weight, set at around 3–6 mg per kg.  If you wish to use caffeine for athletic performance, you should also save it for key events or races, in order to maintain sensitivity to its effects.
