Rehydration in endurance sports with alcohol-free beer

Everyone has experienced this – it’s warm outside, you go for a bike ride and you start craving a real cold drink! Just drink a beer, more precisely: a non-alcoholic beer. Let’s discuss this simple rehydration drink in endurance sports. Cheers ????

Benefits

  • Stomach-friendly 
  • Better taste compared to other iso-drinks 
  • Effective rehydration drink
  • Slightly hypotonic: there is a low osmotic pressure in relation to the blood – thus the fluid balance remains constant
  • Isotonic: the particle concentration of beer is the same as that of blood
  • Hops in beer has a calming effect

Wheat/ Barley contains nutrients that athletes need: 

  • Sodium, 
  • Natural carbohydrates
  • B vitamins: Involved in the formation of red blood cells
    • Vitamin B9 (folic acid)
    • Vitamin B12 – important for vegetarians and vegans, as it is found almost exclusively in animal foods
  • Potassium 
    • Scientifically well proven that potassium can quickly replenish the energy stores in the muscles

Pils or wheat?

  • Both types are equally recommendable
  • Pils comes with less carbon dioxide
  • Non-alcoholic beers are similar due to the purity law

Non-alcoholic beer vs. sports drink

  • Sports drinks contain more sugar
  • Sports drinks sometimes also have less natural vitamins
