Bodybuilding has become the biggest commotion around sodium. Some delight with its beneficial effects, others avoid it like a plague. Namely, some “load sodium” before the competition, others blame him for his failures. Some remove him from the diet a week before the competition, others limit the supply of sodium only for a day or two.

There is a good or bad way to introduce sodium into the bodybuilder’s diet. Here are 10 tips that will put this matter in order once and for all.

Basic advantage

You can believe it or not, but sodium is an element necessary for life. The demand for sodium is higher than for common micronutrients, such as chromium, zinc, iron or selenium. Sodium plays a major role in the nervous system, which in turn stimulates growth, contraction and recruitment (i.e. gradual incorporation of new motor units in the muscle) of the muscles.

Better carbohydrate metabolism

When sodium enters the cell, it stimulates the absorption of glucose. It is consumed as a fuel or used to synthesise muscle glycogen. Sodium is essential for transporting glucose into the muscle cell!

Better protein metabolism

Sodium stimulates the digestive system of amino acids from the gastrointestinal tract to the intestinal epithelial cells, from where they enter the body fluids. In addition, sodium is needed to transport amino acids to muscle cells for their growth and regeneration.

Better thermogenesis

Thermogenesis means the production of heat by the body. Bodybuilders on a diet try to accelerate fat burning by increasing the ability to produce heat. To maintain thermogenesis, adequate sodium intake should be maintained – at least 3g per day.

Demand for a bodybuilder

Although no daily sodium requirement has been established, most caterers recommend a daily intake of 1 to 3 g to cover losses associated with normal sweating. This applies to people who have a moderate lifestyle. Thus, bodybuilders will need more sodium than the average John Smith to cover what they lose during intense training.

Individual demand

Let’s start with 3 grams of sodium as the basic daily dose for a bodybuilder. Now add 1 gram of sodium for each kilogram of weight loss associated with normal water loss sleep and training. If, after a workout, you go, for example, 100kg to 99kg, this means that you should increase the sodium intake to 4g per day.

Stop and expel water

This is where bodybuilders get lost. A sudden increase in sodium results in the release of aldosterone, a hormone that causes water retention in the body. The result is a more smooth appearance, which can make you want to avoid sodium at all costs. But this is the whole trick. If the supply of sodium is high for more than five days, then the reverse scenario occurs: aldosterone excretion is stopped and the body loses sodium and water, leading to a hard, strong appearance.

Off-season supply

Out of season, the goal should be muscle growth, and this requires an increased number of calories from carbohydrates and proteins. The sodium supply should not be limited as it takes part in the metabolism of proteins and carbohydrates, and it excretes with the water we lose during training and sleep. The daily sodium intake should then be at least 3g.

Before the competition

Too many bodybuilders reduce the supply of sodium during the sharpening phase of the diet before the competition. I will give you an example of the beneficial effect of sidu in the days before the show. Many bodybuilders like to have a day off the schedule of their diet. Interestingly, bodybuilders reach for salty things like pizza, fries or hamburgers.

A day or two after this “free” day, believe it or not, look tough and slimmer. Why?

The secret of a “free” day is not just to increase glycogen reserves by eating more carbohydrates; the main role is played by the increase in sodium, thanks to which more carbohydrates enter the muscles. You can see this situation in action on Monday after Saturday’s competition. The bodybuilder eats a powerful, salty meal after the competition and it turns out that he looks better on Monday than on Saturday, on the day of the show. What’s the conclusion? Do not eliminate sodium from the diet just before the competition.

During the competition

If you look great on Wednesday before the competition, there is nothing to combine with water and sodium. However, if you retain water, limit the consumption of sodium without changing the amount of drinks consumed. In order to get rid of water without increasing aldosterone, moderately reduce the amount of sodium in the week before the competition.
