As for intensive exercising the morning after, the news is not great either. A 1993 study of rugby players found a negative effect on aerobic performance even after what the researchers called "the smallest doses": a single unit of alcohol. The day after the night before, it's likely that you will be dehydrated - and exercise will make this worse. You will probably have low blood sugar levels, which means that your exercise capacity will be less. You will not sweat out much alcohol, if any. Gentle exercise might help, but I would suggest that it's important to rehydrate first. Isotonic drinks with higher glucose levels help replace fluid quicker.



Detoxify with a good workout

One man, Nick, who was hospitalised ten years ago due to his heavy drinking and has since regained his full health, lost 17 stone and runs marathons, has noticed that many gym-goers follow toxic nights with what they assume are detoxing workouts and a bunch of vitamins() and nutritional supplements(). There are other people who are really zealous, who have that rigid, 'my body is a temple' approach. Either way, nutritional supplement() regimes will be kinder on you than a glass of wine, despite the nutritional value of the fermented grapes in the wine.

Good quality sleep

A nutritionist who works with bodybuilders, says, good-quality sleep is essential for proper muscle gain, not only because you need to rest in order to be lively for the next day's workout, but also because growth hormone, vital for muscle growth, is released while you're in deep sleep and alcohol can notably affect that quality of sleep. It's also the case that longer-term alcohol use can reduce the rate at which you gain muscle and strength because it can adversely affect blood testosterone levels.

Don't drink after sport

The well-earned post-workout beverage is also a bad idea. The fluid imbalance brought about by sweating is likely to become worse, as alcohol is a diuretic, stimulating urine production and thus increasing dehydration. Alcohol consumption is often associated with poor food choices or with reduced energy and nutritional intake. This may impair recovery. If you do want to go out after a training session, the message should be to make sure you have a good carbohydrate meal first.
