We all know: Alcohol and sports don’t really go together – but it would be naive to say that alcohol doesn’t play a role for athletes.
Especially among amateur athletes, alcohol after the (joint) unit is almost part of it. It’s a social custom to have a beer or two after a workout – or to treat yourself to a “reward glass.”
The average “adult” (>15j.) consumes approx. 4,3l pure alcohol per year, which share athletes make here, is not known. 
However, the type of sport certainly has a certain influence on alcohol consumption. So a little more beer should flow at the apres-ski than after the tennis tournament. In general, there is certainly hardly any athlete who has never celebrated a success or defeat something (more).
There is basically nothing wrong with that either. However, you should be aware of the consequences – and should therefore make your consumption of alcohol after sports (if then) conscious.
Beer or cocktails are not suitable as thirst quenchers after sports. During sports, we lose fluid through sweat. At best, this should be resumed during as well as after training/competition. If too little fluid is supplied, there is a risk of dehydration.
So if you reach for a beer instead of a water bottle right after a workout, it’s not very beneficial for your water balance.
If your drink is stronger than 4%, it has a diuretic effect on your body . That is, the drink promotes your urination and thus of course also the water excretion. Accordingly, it makes more sense to first hydrate properly with a sports drink and if then only later to switch to alcohol.
In a well-hydrated state, 1-2 beers then do not have a harmful effect on water balance. This was found out by Jimenez-Pavon et al. However, this study was conducted exclusively on men and thus the data cannot be directly applied to women. Due to the different body composition, a correspondingly lower consumption already has an effect on the fluid balance for women.
It must also be emphasized that beer is not a super alcohol. As already mentioned, the percentage of the beverage influences the effect on water balance. Thus, if the study was conducted with beer, the data cannot simply be transferred to another beverage.
Unsurprisingly, alcohol weakens the immune system. Susceptibility to infection increases with frequent drinking.
It is important for athletes to know this: After physically high loads, our body is weakened anyway, and we are more susceptible to infections.
If we now combine these two facts, it becomes clear that (too much) alcohol after training puts even more strain on the immune system. It is therefore advisable to supply energy first after the competition in any case.
In this way, you not only protect your immune system, but also avoid a lack of energy. You can read more HERE.
Alcohol can negatively affect injury breaks in two ways.
First, regular (heavy) alcohol consumption increases the risk of injury. This is due to the fact that alcohol reduces testosterone excretion by up to 24%. Accordingly, men are somewhat more affected than women.
Lowering testosterone levels has a negative effect on bone density. Lower bone density indirectly correlates with fracture risk, which ultimately increases the likelihood of injury .
But even if an injury has already occurred, increased alcohol consumption has a negative effect.
If this is the case, alcohol can drag out the rehab process and delay muscle rebuilding. In the following paragraph we will explain in more detail why this is the case.
After muscularly particularly strenuous units, muscle protein synthesis is increased. This process can now be optimized – or inhibited – by the right nutrient supply.
Optimally, high-quality proteins are supplied, which strengthen your muscles and help you to regenerate in the best possible way. Suitable for this purpose would be, for example, our
RECOVERY 8 which contains all eight essential amino acids. This is especially beneficial after muscularly demanding units.
On the other hand, it makes less sense to consume (a lot of) alcohol during the regeneration phase. There is ample evidence that this has a bad effect on muscle protein synthesis. This has something to do with the mTORC1 signal path.
Indeed, alcohol appears to inhibit the activation of mTORC1. Activation of mTORC1 is a key step in increasing muscle protein synthesis after strength training. If mTORC1 is not activated, the synthesis of the muscle protein is hardly stimulated and the effect of the training is absent.
Pair et al. investigated the precise effects of alcohol on muscle protein synthesis. After completed training was administered:
It became apparent that muscle protein synthesis decreased by 37% due to alcohol and carbohydrates compared to pure protein. Combining alcohol with proteins decreased muscle protein synthesis by 24% .
Reduction of muscle protein synthesis by alcohol consumption alone has not been studied. However, it seems logical that the decline would be even greater.
Because most studies on alcohol have looked only at men, Duplanty et al. conducted a study that also included women.
The results of this study showed that the inhibition of mTORC1 was significantly lower in females. Of course, this should not be taken as a free pass to swap water for alcohol after training. The consequences for women were also far from positive.
Furthermore, it must be noted that the data of this study cannot be translated 1:1 into practice. Thus, quantities of alcohol equivalent to about 5 glasses of vodka were drunk (for men 7 glasses of vodka). The amount was drunk within 10 minutes after exercise .
The effect of alcohol on cognitive abilities should also not be forgotten. Reactivity as well as concentration are impaired by alcohol consumption.
If we think of sports such as biathlon, sport shooting or even soccer, this definitely plays an important role. Alcohol also affects the quality and quantity of sleep, which in turn has a massive impact on the immune system .
We can use the findings of science and take 5 tips from it to improve the way we deal with alcohol.
Of course, it makes just as much sense from a health perspective to abstain from alcohol completely. However, we do not want to dictate anything to you, but rather give you practical tips for a more conscious handling of alcohol along the way.
