If you don\u2019t supply necessary nutrients to your body after a workout or competition, your recovery, the key to success in sport, may not proceed in the way you would wish. Optimised post-exercise nutrition is especially important when you have several workout units during the day and you want to quickly recover your energy. <\/strong><\/p>\n Physical exercise is the time when catabolic processes dominate in your body. Muscular activity leading to microinjuries of muscle fibres, depletion of glycogen<\/strong> reserves, increased level of cortisol<\/strong>, called a stress hormone, contributing to fat degradation, protein degradation and mobilisation of body energy reserves, or release of free radicals<\/strong> damaging cell structures, are just a few examples. You must remember that, metabolically, an increase in your fitness takes place after a completed workout and depends not only on its quality and intensity, but also on effective inhibition of catabolic processes<\/strong>, and quick initiation of recovery processes, i.e. making the body enter the state of anabolism.<\/strong> Key factors for an optimal metabolic recovery are adequate intervals between workouts, including a proper amount of sleep and a well-chosen diet<\/strong>.<\/p>\n Nutrition after a workout aims at three basic goals:<\/p>\n Each of them is necessary to regenerate your body.<\/p>\n You could read about hydration before exercise, signs of dehydration, and strategy of fluid replacement during a workout in two previous parts of our cycle:<\/p>\n You probably know that water, the main blood component, decides not only about supplying oxygen and nutrients to your body cells, but also about effective removal of toxic metabolites, such as urea formed in the process of protein degradation, creatinine, uric acid (product of purine base degradation), substances created after haemoglobin breakdown: bilirubin, urobilinogen and urobilin (main urine pigment) or oxalic acid and its salts (oxalates). Water also provides for your body thermoregulation.<\/p>\n What to drink after a workout? <\/strong> Amount of fluids after a workout <\/strong> In order to estimate the amount of water lost during physical exercise, it would be best to measure the difference in your body weight before and after a workout. After a completed workout, you should gradually replace fluids up to 150% of the lost body weight. <\/strong><\/p>\n As a result of having a meal rich in absorbable carbohydrates, the blood glucose level rapidly increases, thus leading to release of insulin by the pancreas. This hormone reveals a strong anabolic effect<\/strong>, which means that it stimulates restructuring and repair of tissues in your body, being responsible e.g. for stimulating glucose transport from the bloodstream to muscle and liver cells. The glucose absorbed from cells is then used for glycogen resynthesis<\/strong>. A quick recovery of glycogen reserves<\/strong> is especially important if your exercise is the endurance type, and if you work out more than once a day.<\/p>\n Anabolic \u201cwindow of opportunity\u201d <\/strong> Endurance sports<\/strong> One workout\/day (or less)<\/strong> More than one workout\/day<\/strong> Strength workout<\/strong> Products rich in carbohydrates, such as wholemeal bread, potatoes, sweet potatoes, pasta, rice, oat flakes, groats, corn or legumes (e.g. chickpeas, lentils or beans) are a good source of carbohydrates, constituting basic fuel for muscles and the nervous system.<\/strong><\/p>\n ZYou have probably heard of an anabolic \u201cwindow of opportunity\u201d, not only with reference to carbohydrates, but also proteins, according to which a post-workout meal rich in protein should be taken immediately after a finished workout. Recent studies, however, cast doubts on the above indicating that a single training session may increase muscle protein synthesis even to 24 \u2013 48 h [2<\/a>, 3, <\/a>4<\/a>] and the key factor influencing its effectiveness is a summary protein intake during the whole day. The duration of an increased activity is individual and depends among others on the type of training stimulus. So, although it is not worth delaying carbohydrate intake after exercise, you do not have to hurry to eat a protein-rich meal directly after a finished workout, but you may take time to prepare it at home, and the protein included in the meal will most certainly be used to effectively restore your muscle fibres. From a practical point of view, having a meal 2 hours after workout will be completely sufficient.<\/p>\n Amount of protein<\/strong> Quality of protein <\/strong> Regularity <\/strong> Whey protein supplementation<\/strong> What to choose in practice? Both WPC and WPI is characterised by high digestibility, high leucine<\/strong> content and rapid (WPC) and very rapid (WPI) absorption. Thus, both products will be a good choice. The difference is in price (WPCs are cheaper than WPIs) and a lower lactose content in WPI, which may be significant for subjects suffering from lactose intolerance<\/strong> and those with gastrointestinal problems<\/strong>.<\/p>\n BCAA supplementation<\/strong>\n
Introduction<\/h2>\n
Nutrition goals after exercise<\/h2>\n
\n
Fluid and electrolyte replacement<\/h2>\n
\n
\nTo restore balance after a workout, you should replace both water and electrolytes. Sodium and chlorine ions (constituting a total of 90% electrolytes lost with sweat), followed by potassium, magnesium and calcium ions, are critical. If your exercise was not very intense or you do not need to recover quickly for the next workout, it would be sufficient to drink medium- or highly-mineralised water<\/strong>, or a good quality \u201czero calorie\u201d sports drink<\/strong>. However, you need to know that water is a hypotonic drink<\/strong>, meaning that its osmotic pressure<\/strong> is lower than plasma. Therefore, water is characterised by rapid absorption, leading to plasma dilution and increased rate of urine output. If you want rapid hydration<\/strong> and speedy recovery<\/strong> after a workout, isotonic drinks<\/strong> will be a better choice. Interestingly enough, good hydration properties are also found in\u2026 skimmed milk<\/strong>. Due to the content of electrolytes (lactose), protein (whey and casein) and many vitamins, milk may fulfil a role of a recovery drink<\/strong>, both after endurance and strength exercise. However, it should not be used by persons with lactose intolerance or those sensitive to milk proteins.<\/p>\n
\nIn order to estimate the amount of fluids lost during physical exercise, it would be best to measure the difference in your body weight before and after a workout. After a completed workout, you should gradually replace fluids up to 150% of the lost body weight.<\/strong> It is essential that post-workout hydration be planned over time, providing small amounts of fluids rich in electrolytes, taken every 20 \u2013 30 minutes until large amounts of straw-coloured urine are produced (you can find more information on the technique of hydration self-study based on the observation of urine colour in Part 1 – what to eat before a workout<\/a><\/strong>). Remember not to drink the whole amount of water at once, since a rapid increase in blood volume has a diuretic effect and increases a risk of hyponatremia (blood sodium deficit)!<\/p>\n![](\"https:\/\/madebydiet.com\/wp-content\/uploads\/2024\/02\/ilosc-plynow-po-treningu-1-scaled.jpeg\")
<\/p>\nCarbohydrates, insulin and resynthesis of glycogen<\/h2>\n
\nWhen you work out at high frequency and you want a rapid recovery after the workout, do not delay carbohydrate intake after you finish your workout. Within the first 30 – 60 minutes after workout, your muscle cells show an increased permeability for glucose,<\/strong> which is related to translocation of the glucose transporter (GLUT-4) from the cell interior to membrane, leading to a more effective glucose uptake from the bloodstream. This phenomenon ensures higher availability of glucose, a substrate for glycogen resynthesis is cells, resulting in the fastest possible glycogen restoration! After an hour, muscle glycogen resynthesis slows down to about 10 – 30% of the initial value. To put this knowledge into practice, do not delay drinking a glucose-containing isotonic drink, an energetic drink, carbohydrate snack or a meal rich in carbohydrates with a high glycaemic index<\/strong>, trying to consume it right after exercise, especially if you plan subsequent workout units fairly soon. When compiling subsequent meals, use a high-carbohydrate diet, which will result in a complete glycogen resynthesis within 24 hours.<\/p>\n
\nIn order to achieve a maximum glycogen resynthesis in endurance sports, take 8 \u2013 12 g carbohydrates a day per kilogram body weight. A specific amount of carbohydrates, however, depends on the workout intensity and volume. So, what should you eat after an endurance workout?<\/p>\n
\nIf the interval between your workout sessions is long (you work out once a day or less), the most important aspect in glycogen resynthesis is a total intake of carbohydrates during the day. In practice, however, you may increase their proportion in the post-workout meal. It is worth placing importance on complex carbohydrates<\/strong> from conventional food, choosing such products as groats, rice, oat flakes or wholegrain pasta.<\/p>\n
\nA different procedure, however, applies to subjects who work out more than once a day, meaning the time to restore glycogen is shortened. In such situations, take 1 – 1.2 g of carbohydrates per kilogram body weight within the first 3 \u2013 5 hours after exercise [4<\/a>,5<\/a>]. Place importance of the sources of carbohydrates with a high glycaemic index >70, e.g. dried fruit, white bread, white pasta or white rice. For example, a female athlete with a body mass of 60 kg should have about 60 g of carbohydrates every hour in the first 4 hours after exercise. In practice, such amount of carbohydrates can be found in 8 rice cakes (80 g), 2 fistfuls of dried dates (90 g), 3 glasses of orange juice (600 ml), or 80 g rice. It may also be helpful to ingest caffeine, which increases the rate of carbohydrate absorption from the gastrointestinal tract. A recommended dose is 3 – 6 mg per kilogram body weight [4]<\/a>. So, if you weigh 60 kg, drinking a double espresso will supply 3 mg of caffeine<\/strong> per kilogram body weight Another helpful strategy to quickly restore muscle glycogen is to combine carbohydrates and protein<\/strong> in your post-workout meal. The addition of protein (0.2 – 0.4 g per kilogram body weight\/ h) will increase the rate of muscle glycogen resynthesis<\/strong>, if the intake of carbohydrates is 0.8 g per kilogram body weight. In the event of higher carbohydrate intake, the extra protein will not additionally increase the glycogen resynthesis<\/strong> [4<\/a>,5<\/a>].<\/p>\n
\nResistance training does not normally deplete glycogen reserves<\/strong> to such an extent that would require immediate carbohydrate replacement. According to available studies, normal carbohydrate intake restores the glycogen reserves<\/strong> within 24 hours. Therefore, carbohydrate intake is not so important for a person doing resistance workout less than once a day.<\/p>\n![](\"https:\/\/madebydiet.com\/wp-content\/uploads\/2024\/02\/produkty-bogate-w-weglowodany-scaled.jpeg\")
<\/p>\nProtein after a workout<\/h2>\n
\nPost-workout meal should include between 0.25 – 0.4 g protein per each kilogram of body weight [2]<\/a>, or, to make it simple, 20 \u2013 40 g protein [3]<\/a>. In practice, 20 g protein is included in 200 g cottage cheese, 120 g lean quark, 100 g chicken breast or 25 g whey protein isolate<\/strong>. In addition, a post-workout meal should include 700-3000 mg leucine<\/strong> (essential amino acid<\/strong>, which promotes muscle protein synthesis) [3<\/a>, 4]. High leucine content can be found e.g. in dairy products, including protein powder supplements, meat, fish or eggs [6]<\/a>.<\/p>\n
\nConsidering the issue of the source of protein in your meal, you should also think about the protein quality. By speaking of quality we mean protein digestibility<\/strong>, as well as an amino acid profile<\/strong>, especially the content of essential amino acids<\/strong>, including leucine<\/strong>, which affect its absorption and use by the body. Animal products, such as dairy or meat, thanks to their better digestibility and more beneficial amino acid profile<\/strong>, will better stimulate the muscle protein synthesis than plant products [6]<\/a>. However, do not completely resign from plant sources of protein, trying to balance meals in such a way as to include both plant and animal protein products.<\/p>\n
\nA growing number of evidence indicates that muscle fibre regeneration<\/strong>, as well as building muscle mass<\/strong> is mostly facilitated by regular protein intake during the day [1<\/a>, 2<\/a>]. or this reason, it seems best to eat 4 – 5 regular meals, each of which contains the 20 \u2013 40 g protein. Numerous studies also indicate that the key aspect for muscle recovery and build-up<\/strong> is also the total protein content during the day. Athletes should consume 1.4 – 2 g protein per kilogram body weight\/day. In certain cases, these amounts will be even higher [3]<\/a>. It all depends on individual issues, including the type and number of workouts and the fitness level of your body.<\/p>\n
\nAlthough protein supplements<\/strong> are not indispensable elements of a healthy diet, and it is usually possible to cover the protein demand using conventional products, in certain situations an additional use of a protein powder supplement<\/strong> may be very helpful. One of the most widely used supplements in sport is whey protein<\/strong>, characterised by high absorption. It is available in two forms which differ in the production process and composition:<\/p>\n\n
\nBCAA means Branched-Chain Amino Acids<\/strong>, i.e. valine, leucine<\/strong> and isoleucine. The above amino acids are 3 of 10 essential amino acids, i.e. such that must be delivered with food, since your body is not able to produce them by itself. These include the above-mentioned: valine, leucine and isoleucine, as well as phenylalanine, lysine, methionine, threonine and tryptophan and also two relatively exogenous amino acids (needed by the body in certain conditions, especially during growth) – arginine and histidine.<\/span> As mentioned above, leucine<\/strong>, a component of BCAA, is an amino acid promoting muscle protein synthesis. Logic tells us that BCAA will be an ideal supplement for muscle development and regeneration<\/strong>. However, available studies deny the popular belief of its effectiveness. According to the Australian Institute of Sport, BCAA has been qualified to Group C supplements, i.e. a group of supplements whose effectiveness… has not been confirmed. Therefore, it is not worth using them, and the money saved could be used for providing an optimal protein intake during the day, so as to deliver all essential amino acids<\/strong> at the same time, preferably from natural sources. What it means in practice? If you eat a product rich in complete protein after a workout, you can increase the muscle protein synthesis<\/strong> even twice as much as when you eat BCAA alonesyntez\u0119 bia\u0142ek mi\u0119\u015bniowych<\/strong> ni\u017c spo\u017cywaj\u0105c same BCAA [7]<\/a>!<\/p>\n![](\"https:\/\/madebydiet.com\/wp-content\/uploads\/2024\/02\/tluszcze-po-wysilku-scaled.jpeg\")
