Caffeine – a pre-workout boost

Caffeine is a chemical compound that has been known for many generations.

It was isolated from grains and brewed into a beverage, but over time, laboratories took over. As a result, caffeine these days can also be produced in a lab and is no different from natural caffeine. Caffeine can be found not only in coffee, but also in tea, chocolate, energy drinks, bars or pre-workout supplements.

Caffeine – how it affects an athlete’s body
Athletes very often consume caffeine before training. This is because it stimulates their nervous system to action. Thanks to this, they eliminate the feeling of tiredness and sluggishness caused by the hardships of everyday life and they can give 100% of their effort during training. Pharmacologically, caffeine is an antagonist (blocker) of adenosine receptors. Adenosine attaches itself to its receptors in the central nervous system, acting on it by inhibiting and slowing it down (to maintain balance). By blocking the place on these receptors, caffeine prevents the inhibitory action of the transmitter, which gives a feeling of excitement.


Caffeine also tends to have an antioxidant effect. This means that it can eliminate free radicals that cause oxidative stress destroying structures at the cellular level. These seemingly trivial facts can turn your life around 180 degrees in the future – it’s worth taking care of your daily dose of antioxidants to avoid exposing yourself to a variety of diseases.

Undesirable effects

Unfortunately, caffeine is not free from adverse reactions and side effects of its use. As long as you don’t exceed certain doses of caffeine specific to each person, nothing should happen. However, when too much caffeine is injected into the body, you may encounter such effects as heart palpitations, insomnia, irritability, irregular heartbeat or breathing problems. These are pretty serious effects, so it’s a good idea to avoid them.
