As a matter of fact. Let's start with a simple one. Alcoholic beer certainly will not save you from dehydration - on the contrary, it will only contribute to it. In addition, there is
that after intensive training (or training during which a person performed complex and unfamiliar exercises) alcohol may prevent the body from recovering. At the same time, yes, we know that at large running starts (especially in Germany), participants are treated to beer.
But this is more a cultural feature than the only right way to make up for lost fluid and electrolytes.
Now let's talk about non-alcoholic beer. With him, everything is complicated and ambiguous. It should be said right away that most of the research (and rather large and serious ones) was paid by beer companies. Among the advantages of non-alcoholic beer, the polyphenols included in its composition are often called - these are plant compounds with antioxidant and anti-inflammatory properties.
So, in the 2012 article , published in the journal Medicine and Science in Sports and Exercise, a study was cited according to which runners who drank one liter of non-alcoholic beer daily a week before Munich and during the week after it, there were fewer cases of inflammatory processes and upper respiratory tract infections compared with runners who took a placebo. However, do not rush to put beer in a sports bag. First, beer is not the only source of polyphenols. These compounds are also found in tea, dark fruits, red wine and coffee. Secondly, the researchers did not measure the concentration of polyphenols in the blood before and after drinking beer.
So we are talking about correlation, not causality.
Nutritionists are also in no hurry to recommend non-alcoholic beer to their customers - in their opinion, it does not contain enough sodium to qualify for the title of sports a drink. In ideal isotonic
there should be
at least 460 mg of sodium per liter. Beer here doesn’t even come close: the amount of sodium varies depending on the brand, but in one liter you hardly count more than 30 mg of sodium. In addition, do not forget about the recommended carbohydrates and proteins after training - it is better to lean on them, and not on beer.
And are you sure that you basically need isotonic? If you train one hour in the gym, normal water will be enough. In addition, a sports drink will simply add extra calories and sugar.
The best advice is to listen to your body and drink water before and during training (if you are thirsty). You do not need to forcefully pour water into yourself (provided you feel good). If you sweat a lot, exercise intensively for more than an hour, or exercise, for example, in the heat, then yes - give preference to foods and drinks that contain sodium.
But remember: without fanaticism.
