Sports nutrition. What to eat before, during and after training

Renat Shagabutdinov, a participant in international marathons, the Comrades ultramarathon, and the Ironman triathlon, tells what an amateur athlete should eat.

In this article we will discuss:

• What is sports nutrition - and is it necessary to use it?
• What the body needs before, during and after training
• What sports nutrition is intended for what purposes?

We'll talk about the basics. For those who want to delve deeper into this interesting and vast topic, read the literature from the list at the end of the article.

What is sports nutrition

Sports nutrition is not doping or “harmful chemicals”, and not something needed only by pros, and not a superfood that can improve results. It's simply a more convenient (and expensive) nutritional format designed with athletes in mind. If you're just starting out as an amateur and run three to four times a week for 40 minutes, or occasionally ride a bike, or go to the pool 3-4 times a week, you probably don't need sports nutrition.

If you have already started participating in amateur competitions or are actively gaining muscle mass, you have long training sessions - sports nutrition can help. If you train a lot (relatively speaking, 10 hours of running a week or 15 hours of training of various types in triathlon) - sports nutrition can be very relevant. Although you can safely do without it by eating rationally, replenishing the water-salt balance and taking vitamins and minerals.

Remember that before using sports nutrition or vitamin-mineral complexes, as well as any other supplements, you should consult with a sports doctor.

The most basic products in sports nutrition:

• Carbohydrate gels are a convenient format for obtaining energy during long workouts and competitions.
• Sports drinks allow you to replenish salts that are lost through sweat; sometimes they also contain carbohydrates, that is, they are also a source of energy.
• Protein mixtures, gainers, recovery mixtures - allow you to restore muscle tissue and (this applies to the last two categories) replenish energy reserves after workouts.

Before training/competition

Under no circumstances should you approach training in a state of dehydration. Drink approximately 400-500 ml of liquid before bed if you train in the morning, and 400-700 ml of liquid in the morning. An hour before training, you should drink 500-700 ml of liquid - and at this time it may not be water, but a sports drink (with minerals, primarily sodium and potassium).

• 3-4 hours before training, you can safely eat up to 4 grams of carbohydrates per kilogram of body weight
• 2 hours before training - up to 2 grams of carbohydrates per kilogram of body weight.
• An hour before training - up to 1 gram of carbohydrates per kilogram of body weight.

Where do you get these carbohydrates from? If you don’t have much time left, you can take a sports drink with carbohydrates or a carbohydrate gel. If 2-3 hours before training or competition - with regular food, rich in carbohydrates, without fat and without protein, and preferably without the products mentioned below. But there are individual characteristics: if you always run after some non-standard food and it is digested normally, if you always drink coffee before training - why not?

To avoid digestive problems during training or competition, avoid these foods the night before and before:

• Fruits and berries. Most fruits are rich in fiber, and berries have even more in percentage terms.
• Vegetables. It's an essential part of a healthy diet, but it's best to be careful before competition.
• Red meat. It's best to save steak for dinner after the marathon. Red meat, rich in fat and protein, takes a long time to digest.
• Legumes. They take a long time to digest.
• Dried fruits. They're a great source of carbohydrates, but they're also high in fiber, just like fresh fruit.
• Coffee. Output quickly. increases acidity in the stomach: it is better not to take risks on the morning of the competition. However, if you have tried drinking coffee many times before workouts of varying duration and intensity and everything was fine, and you can’t wake up without it, then you can drink a cup at breakfast before the competition.

During training/competition

Energy

How many carbohydrates should you consume depending on the duration of your workout?

Less than 45 minutes: no carbs needed (interestingly, some studies show that simply rinsing your mouth with a carbohydrate drink has the same effect during short workouts as consuming carbohydrates by mouth).

45-75 minutes: up to 30 grams per hour - any types of carbohydrates.

2-3 hours: up to 60 grams per hour, carbohydrates should include glucose or maltodextrin.

More than 3 hours: up to 90 grams per hour, a combination of different carbohydrates (for example, glucose, maltdextrin and fructore).

Gels are one of the most convenient foods to fuel during long training sessions and races.

Important note: The gel, like sports bars, is simply a convenient way to deliver sugar to the body. And, as a rule, more expensive compared to “regular” food. About how much more expensive sports food is, for example, there is brilliant material (with quantitative calculations) in Nancy Clark's Sports Nutrition Guidebook. That is, there is nothing magical in the gels - just like in the invigorating effect of Red Bull, Mountain Dew or Coca-Cola, behind which there is mainly a large amount of sugar, and only secondarily caffeine.

In general, what should you pay attention to when choosing a gel?

• On calorie content (how much energy is enough) and types of sugar in the composition (for example, only fructose - rapid absorption, two or three types of sugar - a more distributed supply of energy).
• The taste (you won’t have an appetite anyway - it’s better if you like this sticky rubbish at least a little).
• On the packaging format (the tube is not very convenient for running, it seems to me; not all sachets fit comfortably into a pocket or belt - and so on).
• Presence/absence of salts (You must get salt from one source or another to avoid hyponatremia).

Remember that any gels must be washed down with water, even “isotonic” ones (Iso, Hydro, etc.) should preferably be washed down immediately or after some time. Any gels should not be washed down with sports drinks containing carbohydrates - this leads to the consumption of excessive amounts of carbohydrates and, as a result, to stomach problems.

And one more thing - if you expect an effect from caffeine (which is contained in many gels), stop taking it 1-2 weeks before the competition. Be sure to test any gels during long workouts. You can read a detailed review of gels on my blog.

What alternatives are there to gels?

• Baby food.
• Kissel - ready-made or powdered, which you prepare yourself. You can add sugar, honey, amino acids - everything according to your taste and needs.
• Energy bars (hard to chew, especially if you're running fast - might be fine on a bike).
• Special sports chewing candies (not always convenient to chew, but you can dose nutrients and caffeine more accurately and eat in smaller portions) Main manufacturers - GU, Gatorade, Clif, Powerbar.
• “Normal” food (if you have access and if you can digest it on the run):

Any food that is low in fiber and has a sufficient amount of carbohydrates (select servings at the rate of 30-60 grams per hour).

These criteria include vegetable and fruit juices, canned fruits, granola, crackers, gummies, jams, white bread, bagels, pretzels, raisins, boiled potatoes and much more.

Pancakes, pancakes, pancakes (and the now popular “oatmeal pancakes”) are rich in carbohydrates, source.

Test it in training so that you can use what you learn well in competitions. And, of course, drink the required amount of water.

Questions before, during and after reading a fiction book

Some people read 10 books a year, some 50, some even more. However, we all understand one simple truth: the quality of information and the level of its understanding are important. To encourage critical reading, you need to learn to ask the right questions. This will help you to take a more conscious approach to the book and get a lot more out of it.

In our article we will talk about fiction, but if you really want, the questions can be remade and used for reading professional literature.

Why is this so important?

Reading books is an element of learning, self-development, and one of the most useful ways to spend time. You need to get the most out of every book. Deep understanding is incredibly important because characters and dialogue can be forgotten over time, but the essence remains.

Dolores Durkin conducted a study in 1979 and found that the vast majority of teachers and teachers ask questions only after finishing reading a book, and very rarely before and during. Further study showed that the situation did not get much better over time.

Meanwhile, there are great advantages in such reading:

• Understanding why this book is needed at all
• Ability to make assumptions
• Learn to create connections and associations
• Use context when encountering unfamiliar words
• Evaluate text quality
• Revise key points in the text
• Understand how the information can be used in the future

Before questions

You have chosen an interesting book, made yourself comfortable and are ready to read. But first, ask a couple of questions to help you perceive the text more consciously:

• What clues does the book's title give me about the plot and story?
• What will the book be about? Why do I think this?
• Is this a real or fictional story?
• Why am I reading this?
• What do I already know about this book and its topic?
• What assumptions can I make?

Questions "during"

Take several breaks while reading. Ask yourself a few questions about the chapter you are reading:

• What did I understand from what I read?
• What is the main idea?
• What picture did the author paint in my imagination?
• Do I need to reread this chapter to understand it better?
• What will the character do? Why?
• What emotions does the character experience?
• What would I do in his place?
• Has something similar happened to me?
• Describe what you read in your own words.
• Do I need to memorize this text? Why?

Reread this chapter and ask yourself the following questions:

• Which assumptions were correct?
• What is the main idea really?

Questions "after"

• At what level of understanding of the text was I? Isn't there a deeper meaning?
• What questions did the author pose to himself and how did he answer them?
• What were the author's intentions or did he completely try to distance himself from the intentions and his point of view?
• Did the author answer all of his questions or were some answers incomplete?
• If there was a sequel, what could it be?
• Can you tell the story in your own words?
• What events were the most important?

All these questions will help you not just read the book, but get great benefit from it.

If you are a teacher

Your main responsibility as a teacher is to engage your students in conversation and find out what they think about the book.

• Why did the author place the characters in this place and time?
• Why did the author start the story this way?
• Why did the author end the story this way?
• What questions would you ask the author?

This approach can be used when studying:

• Fiction
• Science
• Mathematicians
• Writing skills
• Social Sciences

You can come up with questions yourself. The main thing is to treat the text consciously. It’s better to read fewer books, but feel them as deeply as possible.

We wish you good luck!

Water-salt balance

Water and dehydration

For normal functioning of the body, you need 30-35 ml of water per kilogram of body weight per day. Accordingly, during training we lose more fluid through sweat. Dehydration (low fluid levels) is most easily identified by the color of your urine. If it is bright yellow or dark coffee-colored, most likely you need to replenish your body's water reserves.

In addition, symptoms of dehydration include fatigue, headache, loss of appetite, dizziness, and nausea.

With dehydration, body temperature and pulse increase, additional stress appears on the cardiovascular system, and blood volume decreases. Dehydration negatively affects the training process and carries health risks. Before any workout, you need to make sure you drink enough water - and there's no better indicator than the one already mentioned

Basic recommendations for drinking water and/or sports drinks during exercise are 120-240 ml every 15-20 minutes.

Using the following formula, you can calculate the fluid loss per hour for yourself. Volume of fluid loss: (body weight before training - body weight after training + fluid intake _ fluid loss (with urination) / training time.

Drinks with electrolytes

Water alone is not enough - with sweat we lose salts, and these losses need to be replenished.

Note that the need for salts does not depend on the duration of the load, but on sweating. Accordingly, in hot weather you need to pay more attention to replenishing electrolytes.

Carbohydrate concentration: what types of drinks are there?

Research shows that a carbohydrate concentration of 6-8% in a drink is ideal in terms of speed of absorption. Such drinks enter the bloodstream as quickly as water, but provide you with energy. They are called isotonics.

And drinks with a carbohydrate content of up to 10-12% - hypertensives (juices, carbonated water, carbohydrate gels - even those called “isotonic”) - are no longer so effective in terms of hydration rate. They need to be diluted if you want to drink them during training.

What are the options?

• Make your own sports drinks (Regidron, which can be bought at any pharmacy for little money, has enough electrolytes to make plenty of your own isotonic drink. Dilute half or even a third of a teaspoon in a liter of water, add glucose or fructose and sugar, honey, sap or maple syrup).
• Buy ready-made drinks from Powerade, Gatorade and other brands - in bottles (pay attention to the amount of sugar - there is usually quite a lot of it, which can be both a minus and a plus. For example, you can do without gels during a fairly long workout)
• Buy powders or soluble tablets and prepare the solution yourself. There are a lot of such drinks - both in tablets (GU, Isostar, High5 and other brands) and in powders (you can buy the drug "Regidron" at any pharmacy - it will cost less; in addition, almost all sports nutrition manufacturers have sports drinks in powders — study the composition, they can be more/less sweet, with or without amino acids)
• Tablets are especially convenient if you are traveling and the destination is hot, and there is nowhere to buy a ready-made sports drink.

Can mineral water replace isotonic water? Yes, maybe, and medicinal table mineral water (from 1 to 10 g/l of salts) is best suited for this. But sparkling water can irritate your stomach - keep that in mind.

What is hyponatremia?

This is a state of low sodium concentration in the blood (below 135 mmol/L). In sports, it usually occurs in the heat and under heavy loads. Those at risk are those who drink a lot of plain water and do not replenish the loss of electrolytes (primarily sodium) with the help of isotonics, hypotonics, salt tablets, salt, salt gels and other sports and regular nutrition. According to a study published in the New England Journal of Medicine, 13% of Boston Marathon participants experienced mild hyponatremia because they drank too much water. The first signs of hyponatremia: nausea, rapid weight gain, colorless urine, convulsions.

Signs of more serious hyponatremia: apathy, dizziness, stupor, loss of orientation in space, very severe fatigue and lethargy, vomiting. Even coma is possible.

A 40-year-old Australian competitor died at the 2015 Ironman Frankfurt competition. The triathlon took place at a very high temperature, it was 40 degrees. The athlete lost consciousness immediately after the finish and died after two days of resuscitation. A diagnosis was made of cerebral edema caused by a lack of salts in the body.

The consequences of hyponatremia can be so tragic, and therefore replenishment of electrolytes, and especially sodium, in the heat should be taken as responsibly and seriously as possible.

Post-workout carbohydrate window for bulking

As we know, muscles grow after exercise, when our body restores them, trying to make a reserve so that they can withstand the load next time.

After training you can drink cocoa with milk

To gain muscle mass, you must close the protein-carbohydrate window after training by taking fast carbohydrates.

Most often, so-called gainers are taken for these purposes - protein-carbohydrate cocktails.

You can easily prepare such a drink at home and take it with you to the gym so as not to waste even a minute of precious time.

Mix half a banana, half a glass of milk, 50 g of cottage cheese and 40 g of steamed oatmeal in a blender.

The portion is small: just what you need. We take the container out of the bag, shake it up and drink the cocktail right in the locker room.

This drink is very easy to digest, and valuable substances will enter the blood quickly, which is important.

To speed up muscle recovery and maintain muscle growth, you need to use the protein window, which opens at approximately 23:00.

At this time, you can eat cottage cheese and go to bed calmly, knowing that the body will do everything right and muscle mass will increase.

What foods are best to close the carbohydrate window after a workout:

1. Honey
2. Jam
3. Fruits and dried fruits
4. Buckwheat
5. Rice (brown)
6. Low-fat dairy products

After your workout, you can indulge in a spoonful of your favorite jam.

After training/competition

Immediately after exercise, you need to drink drinks with a high sodium content (500 mg / liter) and eat foods high in carbohydrates and proteins (for example, cherry pie and chocolate milk or a tuna sandwich or a special sports nutrition - a recovery drink or gainer). Ideally, 30 grams of protein in the first half hour after a hard workout and 1.2 grams of carbohydrates per kilogram of body weight.

This amount of protein is not always easy or convenient to consume with regular food.

Therefore, if necessary, you can and should use supplements - protein in mixtures, drinks, bars. Remember that it has no advantages over protein from regular food, and is not a “chemical”, “doping” or superfood. It's simply a convenient form of protein that can help you get the right amount of this nutrient.

Protein can be soy, whey, egg, casein, or milk.

Source

They differ in the speed of absorption: whey is the “fastest”, casein is the slowest. That is, after training, you can drink the first one for quick recovery.

Many bars, gainers, and protein powders contain multiple types of protein.

A number of studies have shown that a combination of carbohydrates and protein is better for restoring glycogen stores after exercise than carbohydrates alone. This is because the mixture of proteins and carbohydrates stimulates a greater release of insulin, which in turn accelerates the absorption of glucose and amino acids from the blood into the muscles.

When it comes to sports nutrition, the best option is recovery mixtures or gainers - mixtures of proteins and carbohydrates (often also with vitamins). Please note that mass gainers are intended primarily for weight gain - and the carbohydrate content per serving may be excessive. Recovery drinks usually have a more suitable composition.

Therefore, read the label, reduce the portion if necessary, or drink a protein mixture, adding sugar, honey or banana to it - you will get the same gainer.

Is it possible to eat more protein than you need? It is harmful?

Eating more protein than you need isn't that hard unless you count it and stick to a vegetarian diet (and especially if you take a supplement).

But this is not scary or harmful - the excess is processed into urea and then excreted from the body or used as fuel (processed into energy or stored as fat reserves if you have a positive calorie balance)

Fish is a source of protein. Choose the one you like - source.

How much water do you need after?

Fluid loss during exercise is calculated as follows: weight before exercise - weight after exercise. The result obtained must be multiplied by one and a half - and the resulting volume of liquid must be drunk within three hours.

Example: before training we weighed 67.1, after - 66.2.

In the next three hours you need to drink:

(67.1-66.2)*1.5 = 1.3 liters of liquid.

Carbohydrate window after exercise for weight loss

Yes, there is an opinion that it is better not to eat after training to lose weight.

Then the body will begin to use fat to replenish energy reserves.

After any exercise, be it cardio or strength training, the process of muscle mass destruction begins. In order not to lose the muscles that you have, you should definitely take protein.

After your workout you can eat a slice of cheese

How to close the carbohydrate window after a weight loss workout?

The most suitable options would be the following:

1. A glass of milk + a spoon of honey
2. Natural yogurt + a spoonful of honey or your favorite fruit
3. Fresh fruit + slice of cheese
4. Fruits with nuts
5. Cocoa with milk

It is believed that when cutting, women should not close the carbohydrate window after training.

But how can this postulate be combined with the fact that drying out without normal muscle volume is pointless and harmful?

After all, by not closing the window, we contribute to the destruction of muscle tissue. So you can soon turn into a mummy.

Therefore, we conclude that it is still necessary to close it, and it is not necessary to gorge yourself at the same time, you can simply eat a tiny portion of protein food.

And you can achieve good results with the help of enhanced exercises supported by diet.

What to eat after training for muscle growth

Exercising in order to build muscle mass should be combined with a certain type of nutrition.

You need to eat according to the following rules:

• Start eating half an hour after completing the exercises;
• Eliminate fatty foods from the diet;
• Take protein foods, which can be purchased in specialized stores;
• Increase your consumption of egg whites;
• Drink a lot of water.

One and a half to two hours after class, you can have a snack of lean meat with a side dish, an omelet or a pasta casserole. The protein base should contain proteins of both animal and plant origin.
