Summary: Combine carbohydrates and protein to optimize recovery. Customize intake to your form of exercise and goals.
Eat after exercise - what should you really eat?
Protein: building blocks for muscle repair
When we exercise, especially during strength training, little injuries occur in the muscles. It is a natural and necessary process for building strength and endurance. Here, protein plays a central role by helping the body repairing these injuries and strengthening the muscles for future challenges.
Protein is made up of amino acids, which act as the body's own building blocks. One of the most important amino acids for recovery is leucine, which starts the body's repair process and stimulates new muscle building. Grenade amino acids (BCAA), with leucine at the forefront, also help to increase muscle protein synthesis and reduce the degradation of protein. At the same time as the muscles are repaired, other important functions in the body are also activated, such as hormone production and enzyme activity.
How protein helps the body recover
Protein does more than just repairing muscles. It also contributes to the production of enzymes, hormones and immune cells that are crucial to the body's recovery. Research shows that muscle protein synthesis can increase by as much as 72 % during the first 96 hours after strength training. This shows how important it is to add enough protein for several days after a workout.
Getting enough protein not only helps the muscles recover faster, it can also reduce exercise pain, promote muscle growth (hypertrophy) and improve the total recovery.
Right protein intake after exercise
To take full advantage of the effects of the protein, timing and amount are crucial. It is recommended to consume 20-30 grams of protein within 30-60 minutes after training. This corresponds to approximately 0.25 grams of protein per kilo of body weight, or a total of 20-40 grams.
"Protein is made up of amino acids, which act like building blocks for the body. When you eat protein after an activity, it gives your muscles the amino acids necessary to repair and rebuild." - Stephanie Howe, PHD
To maximize muscle protein synthesis, each meal should contain 10-15 grams of essential amino acids, including 2-3 grams of leucine. Protein intake should also include 700–3,000 mg of leucine along with a balanced amount of essential amino acids.
The quality of the protein is as important as the amount. Proteins that are quickly absorbed by the body and contain high levels of essential amino acids, especially leucine, are most effective. Some examples of good protein sources are:
- Whey protein - Popular with athletes thanks to their complete amino acid profile and rapid uptake.
- Casein protein - Slowly melting, perfect to take before bedtime.
- Soy protein - A milk -free alternative that contains all essential amino acids.
- Pea protein - A high quality alternative that is rich in arginine.
A 2017 study showed that female college athletes who took whey protein before and after exercise increased their maximum strength in bench press by 4.9 kg, compared with only 2.3 kg in the control group over an eight -week period.
For those who exercise hard, the need for protein is higher than for those who are sedentary. The recommendation is 1.4-2 grams of protein per kilogram of body weight per day. This need reflects the increased demands that exercise places on muscle building and recovery.
Carbohydrates: restore the energy layers
While protein helps to repair muscles, carbohydrates are crucial to replenishing the body's energy supply. They act as the body's main fuel and restore the energy storage that is emptied during physical activity.
In exercise exceeding about 60 % of maximum oxygen uptake capacity, muscle glycogen and blood glucose are consumed at a high rate. Immediately after exercise, insulin production increases, which allows accessible glucose to be quickly converted into glycogen and refills the energy depots again. Glycogen refill takes place in two steps: first a rapid insulin -independent phase, followed by a slower insulin -dependent phase.
To ensure an efficient recovery, an average glycogen filler speed of 5–6 mmol/kg of wet weight per hour is required. This makes it possible to restore glycogen levels completely within 24 hours, which requires a continuous intake of carbohydrates.
Why carbohydrates play a role
Carbohydrates are especially important for athletes because they provide the energy that the muscles need during high -intensity exercise. If carbohydrate layers are insufficient, performance can deteriorate. One study showed that elite times that followed a low carbohydrate, high fat diet for three weeks experienced a worse training economy.
Different types of carbohydrates fulfill different functions: simple carbohydrates provide rapid energy and facilitate recovery, while complex carbohydrates provide a more long -term energy supply. The timing of carbohydrate intake is also crucial. Eating carbohydrates within 30 minutes after exercise can increase muscle glycogen synthesis by up to 40 %, while a two hour delay can reduce the synthesis by 50 %.
Timing and quantities for carbohydrates
For best results, it is recommended to consume 1.5 g of high glycemic carbohydrates per kilo of body weight immediately after exercise, followed by 1.0–1.2 g per kilo of body weight per hour during the following four hours. When rapid recovery, 0.5–0.6 g per kilogram of body weight every 30 minutes for 2-4 hours can be effective.
The Academy of Nutrition and Dietetics suggests that carbohydrates should be taken within an hour after intensive exercise. For longer workouts, which last over 60 minutes, it is recommended that athletes take 15-30 grams of simple carbohydrates during the activity itself.
"Carbohydrates post-workout help the body release insulin, which in turn restores the glycogen stores that were just used during your training session." - Anthony Dimarino, RD, CPT
Glucose is the most effective form of carbohydrates to quickly replenish glycogen stores after exercise. Repeated intake of 1.0–1.2 g of carbohydrates per kilogram of body weight per hour can lead to high glycogen synthesis speeds of 10–11 mmol/kg wet weight per hour. This is especially important for athletes who exercise several times a day or have a short recovery time between the passports.
For those who do not need to perform at the top of several workouts the same day, it is less important to immediately restore glycogen levels. This provides greater flexibility in carbohydrate intake during the day. Regardless of the target, it is important to combine carbohydrates and protein to optimize recovery and ensure a balanced nutrition after exercise.
Protein vs carbohydrates: What does the biggest role?
When we try to determine whether protein or carbohydrates are most important, we must take into account the type of exercise performed and how the combination of these nutrients affects recovery. Both are important, but their role varies depending on your training goals and levels of activity.
The impact of exercise type
In strength training, protein is crucial to repairing and building muscle, while endurance training mainly requires carbohydrates to replenish energy supply. Research shows that resistance training that lasts longer than 45 minutes can reduce the glycogen layers in type II muscle fibers by 24-40 %. Here, protein plays a key role in stimulating muscle protein synthesis and accelerating recovery.
For endurance sports, carbohydrates are even more important. During high -intensity exercise, the body can consume almost all its glycogen warehouses in 60-90 minutes. If the layers are completely emptied, it may take up to 18-24 hours to restore them.
For training forms that combine strength and endurance, such as crossfit, both energy from carbohydrates and protein is needed to repair muscles. Here, a balanced combination of the two nutrients becomes crucial.
Benefits of combining protein and carbohydrates
Combining protein and carbohydrates after exercise offers several benefits. It improves both glycogen synthesis and muscle recovery. Research shows that a simultaneous intake of carbohydrates and protein (Cho-Pro) can lead to higher glycogen synthesis than if carbohydrates are only consumed. This is partly because amino acids such as leucine stimulate insulin release, which helps to store glycogen more efficiently.
A meta -analysis has also shown that the combination of carbohydrates and protein improves endurance and performance compared to consuming carbohydrates alone.
Recommendations from ISSN: During the first four hours after exercise, an intake of about 0.8 g of carbohydrates and 0.2–0.4 g of protein per kilo of body weight is recommended every hour for optimal recovery. A common relationship between carbohydrates and protein is 3: 1 or 4: 1. This means that, for example, you eat 60 grams of carbohydrates, it should be combined with 15-20 grams of protein.
Studies also show that it is possible to reduce carbohydrate intake by about 30 % without impairing glycogen synthesis, as long as protein is consumed simultaneously. This opens up a more flexible strategy where recovery is maximized without exaggerating carbohydrate intake.
To ensure both glycogen refill and muscle repair, an energy intake of about 1.2 g per kilo of body weight per hour is recommended, combined with 0.25–0.3 g of protein per kilo of body weight per meal. By customizing your intake to the training type, you can optimize your recovery and reach your goals faster.

Customize your nutritional intake to your training goals
Adjusting your intake of protein and carbohydrates by what type of exercise you perform can make a big difference to your recovery. Here we go through how you can balance these nutrients to optimize the results depending on your form of training.
Nutrition intake for strength training
In strength training, protein is the key to repairing the muscles after micro damage has occurred in the muscle fibers. For best recovery, a carbohydrate/protein ratio of 3: 1 or 4: 1 is recommended, which means, for example, that you can combine 30 grams of carbohydrates with 7.5-10 grams of protein within 30-60 minutes after exercise.
Research from Power et al. Shows that 45 grams of whey protein isolate maximizes muscle protein synthesis for up to two hours.
Strength training tips:
- Choose high quality protein sources such as lean meat, eggs, dairy products or herbal alternatives.
- Eat a meal within two hours of training to support the recovery.
- Add some carbohydrates to the meal to improve the body's protein uptake.
Nutrition intake for endurance training
For endurance training, carbohydrates are crucial to replenishing glycogen layers. If you eat meals with 45-65% carbohydrates, the body can store about 2 grams of glycogen per kilo of muscle tissue, as well as 100-125 grams in the liver. This provides energy for about two hours of running at moderate intensity.
| Training hours per day | Carbohydrate needs (g/kg body weight) |
|---|---|
| 1 hour | 5 g/kg |
| 2 hours | 6 g/kg |
| 3 hours | 7 g/kg |
| 4 hours | 8 g/kg |
| 5 hours | 9 g/kg |
| Over 5 hours | 10 g/kg |
E endurance athletes also need between 1.2 and 2.0 grams of protein per kilo of body weight per day. After training, you should aim to get 10-20 grams of protein to promote recovery and strengthen the immune system.
"Percentages are meaningless, because it is the absolute amount of carbohydrate and protein that matters. How much you need depends on your goals and the amount of training you do." - Asker JeudeDrrup, Ph.D., training physiologist at the University of Birmingham in England
Balance macronutrients for mixed exercise
If you are engaged in training forms such as crossfit, which combines endurance and strength, you need a balanced strategy to both replenish glycogen and repair muscles. A good distribution of macronutrients is 55% carbohydrates, 25% protein and 20% fat.
Recommendations for Mixed Exercise:
- After exercise: Take 0.8 grams of carbohydrates and 0.2 grams of protein per kilo of body weight.
- Repeat the same intake after two hours during a four -hour recovery period.
- For longer workouts (over 60 minutes): Aim to get 30-60 grams of carbohydrates per hour.
For activities that last for over four hours, up to 5 grams of protein per hour can help support muscle repair.
Conclusion: Optimize recovery after exercise
Carbohydrates and protein play a central role in recovery after exercise. Lee M. Margolis from U.S. Army Research Institute of Environmental Medicine explains:
"We believe by matching the energy content in the current sports current recommendations for optimal glycogen recovery of 1.2 g · kg - 1S -1 by lowering carbohydrate intake (0.9 g · kg - 1) and adding the corresponding amount of protein (0.3 g · kg - 1) can not be achieved glycogen synthesis but also stimulate muscle protein synthesis. "
A balanced strategy, where carbohydrates and protein are combined, is the key to maximizing both glycogen recovery and muscle building. Research shows that at the same time intake of these nutrients not only stimulates muscle protein synthesis but also improves recovery and performance.
The International Society of Sports Nutrition emphasizes the importance of balanceing the intake of these macronutrients to optimize recovery. For endurance athletes, a 4: 1 relationship is often recommended between carbohydrates and protein to maximize performance and recovery. Nutritionist Brad Sly emphasizes this:
"Ideal nutrients after exercise vary depending on your training goals; if you train to run a marathon, your recovery will differ if you try to lose a few pounds."
Timing is also important. Eating within 30-60 minutes after exercise is crucial to utilizing the body's highest susceptibility to nutrients.
However, it is important to adapt the strategy to individual needs. Factors such as age, gender, exercise intensity and personal goals affect the nutritional needs. By adjusting both the amount and the timing of your nutritional intake, you can optimize the recovery and take a step closer to your training goals.
