First, you want a carbohydrate that has a high glycemic index e. Remember, insulin is the carrier of the nutrients so you want to ensure a boost in insulin levels.
Further, hyperinsulinemia high insulin levels suppresses amino acid decreases and prevents a negative nitrogen balance, which is normal after training. You want nitrogen to at least be maintained, or more ideally positive-working out will cause a shift in this system, though, and because you're actually breaking down muscle tissue during this period, you'll be in a negative nitrogen balance if not properly fed i.
Since carbs do nothing to enhance nitrogen balance, which is dependent on protein intake, you need to also ensure protein is a component of your post workout drink or meal PWO. When hyperinsulinemia is coupled with high quality, quick acting protein, such as whey protein isolate and free-form amino acids, there is a synergistic relationship that occurs among them.
Specific amino acids independent of whole proteins, are potent stimulators of protein synthesis and recovery and could help enhance immune status during and after intense training and promote a positive nitrogen balance, as alluded to earlier.
When I say free-form amino acids, I'm not suggesting taking a handful of pills with your post-workout meal. There are actually specific aminos that have been shown to independently stimulate skeletal muscle protein synthesis.
Leucine has been shown in several studies to independently stimulate skeletal muscle protein synthesis. In fact, in one particular study, recovery of muscle protein synthesis was stimulated by leucine supplementation and was not dependent on plasma insulin levels.
This suggests that leucine, in combination with carbohydrate, can enhance recovery. One study reported that the anabolic effect of a complete mixture of amino acids can be reproduced with the branched chain amino acid leucine alone.
Next, although whey protein isolate is naturally high in the amino acid glutamine , additional doses of this amino acid are recommended because exercise or any stress lowers plasma glutamine levels.
Several studies have demonstrated that maintaining baseline levels actually enhances the immune system by reducing the risk of illness and infection.
Therefore, glutamine may be effective as part of a recovery beverage. Well, first and foremost, you don't have to use a recovery beverage.
I personally prefer them; they are not only absorbed more rapidly, but they also contribute to your fluid intake, which an overall important part of recovery. There are a number of research studies in this area; some of shown a positive effect from carbohydrate-protein in a ratio, some have shown a ratio, and others a ratio, meaning for every 2, 3, or 4 grams of carbohydrate, you consume 1 gram of protein.
To put it another way, if you were consuming 60 grams of carbohydrate, you would consume 30 grams protein , 20 grams protein , or 15 grams protein Still with me?
There is also enough supportive research to show approximately 3 grams of leucine in addition to that which you'll get from the whey and 5 grams of glutamine are effective. If you prefer 'real' food, determine what foods meet these requirements and enjoy. Keep in mind that you do not want fat or fiber in this meal, as both slow down the absorption.
Moreover, aside from pre- and post-workout and maybe during , it's the one meal of the day you should consume simple, high glycemic carbs so enjoy and you'll be on your way to recovery and growth. This is just a quick summary of the topic.
They tend to be vilified in the nutrition world, but many people don't realize that their bodies run on carbohydrates. Your body relies on carbohydrates — in the form of glycogen — to get you through that grueling spin class or your favorite workout video according to Len Kravitz writing for the University of New Mexico.
Read more: Burning Fat Vs. Glycogen is a polysaccharide that serves as an energy storehouse. Glycogen is found in the liver and muscles.
The muscles convert glycogen into usable energy and your body utilizes your glycogen stores throughout the day according to The Sport Journal. This is why it's important to maintain proper nutrition to keep those muscle glycogen stores replenished.
With exercise, those stores are quickly depleted. Your body stores enough glycogen to last 12 to 14 hours of daily activity. That same amount of glycogen will get you through two hours of sustained exercise. While the body uses glycogen at the beginning of any exercise, the body will eventually use fat stores for energy, but glycogen is required to convert the fat into usable energy.
Glycogen is the fuel in your gas tank that you need to keep going. Read more: How Long Can the Body Use Glycogen as an Energy Source During Aerobic Exercise?
The best time to replenish your glycogen stores is within 15 minutes of completing your workout according to ACE Fitness. If carbohydrates are consumed immediately after exercise, the body is able to retain up to 50 percent more glycogen.
Depending on the length of exercise and muscle fibers involved, it can take between 22 hours to four days to completely replenish your glycogen supply. The maximum window for "best-case" glycogen replacement is two hours post exercise.
The consequences of not replenishing the muscle glycogen stores are dire. If not properly fed, the body will start consuming muscle in order to fuel itself. Before a lengthy athletic event like a marathon, participants will often "carb-load.

Commencing a bout of exercise with reduced muscle glycogen levels impairs exercise capabilities, meaning that restoration of muscle glycogen is vital if optimal performance is desired. The primary trigger for glycogen synthesis refueling is carbohydrate ingestion.
In addition to replenishing carbohydrates-based stores, the body also has in place a set of processes to quickly repair the muscle damages induced by exercise. The biggest triggers of muscle protein synthesis repairing and building muscles are eating protein.
Appropriate doses of protein can maximally stimulate muscle protein synthesis. Given the main focus of this article we refer the interested reader elsewhere for further readings. The more correct answer? Within the first 2 hours, there is a key recovery window that can be used to maximize recovery and delaying ingestion of carbohydrates results in a reduced rate of muscle glycogen storage.
A bout of exercise influences glycemia both during and after, and this can persist for up to 48 hours post exercise due to changes in insulin sensitivity and muscle glucose uptake. Therefore, the post-exercise period includes everything from immediately post-exercise until 48 hours post-exercise and potentially longer if there is severe muscle damage or after exhaustive endurance exercise.
It is important to note, that in the real world, athletes compete or train much more regularly than every 48 hours, sometimes competing multiple times per day, depending on their event.
Therefore, the athlete must have a good understanding of which aspects of recovery they prioritize so that glycemia is optimal and energy substrates have recovered to facilitate future performance.
The process of muscle glycogen synthesis begins immediately following exercise and is the most rapid during the first hours of recovery. Glycogen synthesis after a bout of exercise occurs in a biphasic pattern, the insulin dependent and independent phases.
In the initial post-exercise phase, there is a rapid increase in glycogen synthesis for mins. This is independent of insulin and reflects the initial recovery phase post exercise. This initial rapid glycogen synthesis will slow if carbohydrates are not ingested.
The above described insulin-independent phase, is suggested to occur when glycogen is depleted at the end of an exercise bout.
It seems that the mechanism responsible for the initial rapid phase of glycogen synthesis is the same contraction mediated glucose transporter type 4 GLUT4 translocation that turns glucose rushes into glucose rises when walking post meal. Additionally there is augmented glycogen synthase activity.
The second phase of glycogen synthesis has been defined as the insulin-dependent phase. Scott et al, Insulin increases blood flow to the muscle, GLUT4 translocation to plasma membrane, hexokinase II and glycogen synthase activity, which all contribute to increased glucose uptake by the muscle and glycogen synthesis.
Research in athletes has shown that the rate of carbohydrate delivery potentially can be augmented via certain strategies such as use of alternative carbohydrates, congestion of protein and caffeine.
Protein and carbohydrates work together in the post exercise window, allowing for improved protein metabolism as well as improved glycogen synthesis when compared to carbohydrates alone. Glycogen storage is not impacted by source of carbohydrates when comparing liquids and solids.
In addition to carbohydrates, insulin secretion can also be induced through ingestion of certain amino acids. This evidence led to the strategy of accelerating post-exercise muscle glycogen synthesis with the co-ingestion of carbohydrate and protein.
However, when carbohydrate intake is adequate e. Interestingly, inducing a glucose rush if this is in response to a carbohydrates-based meal can be an indication that your body is in an anabolic state, ensuring that glycogen stores are being refilled.
During this time phase, insulin is secreted to support glucose uptake by the cells but also protein synthesis in the muscles. This is perhaps why the co-ingestion of protein and carbohydrates have synergistic effects above caloric matched ingestion of one or the other individually.
Yes, you read that right, whilst generally you want to stay in the blue zone, and this is possible even with higher carbohydrate intakes when changing meal order or altering meal composition a little to include fibre and some fat, for example, a bit of a spike post meal in the window of time post workout is probably not detrimental.
Your carbohydrate requirements are at least in part related to your intake prior and during training — in your Prime and Perform windows. Beyond this, they are dictated by the intensity and duration of your activity, with consideration given to whether you want to optimize recovery or intentionally not do so.
It should be recognized that these recommendations are in the context of total output for a week as well as after one training session, as is the nutritional intake.
With respect to protein, dosing is more related to maximal muscle protein synthesis than total dosing requirements. As caloric intake increases, protein will naturally go up. The requirements of protein to ensure maximal muscle protein synthesis vary based on age, energy intake more protein is needed in times of energy restriction and recent training stimulus resistance training increases muscle protein synthesis.
When planning multiple sessions per day or multiple sessions with a short time between, rapid restoration of glycogen stores may be required. If this is the case and recovery time is less than 4 hours, you may consider the following right after your workout:.
When looking to optimize recovery without another session in a short time frame, it has been suggested that ongoing, regular intake of carbohydrate and protein every hours will maintain a rapid rate of muscle protein synthesis and glycogen synthesis, provided this starts relatively soon after exercise.
The good news is that your post training session social meal might be the perfect recovery protocol even perhaps with the addition of a good coffee. Make sure you eat enough protein and carbohydrates in the post workout window.
The challenge is to ensure this is soon enough after your training session and you keep refueling properly afterwards. Remember, recovery from one session is aiding in your preparation for the next one within your Prime-Perform-Recover endless energy cycle see below.
Key Recovery Points : Use your post-workout window - eat some carbohydrates and protein as soon as possible post workout. Ensure that you are recovering appropriately after the initial post-workout window by meeting caloric and protein needs.
Recovery is as much about acute adaptation to the session you just finished as it is about preparing well for your next session. What are the basics of recovery nutrition? Repair: Eat enough protein. Rehydrate: Drink enough to replace fluid losses. Rest: Get good sleep and have nutrition that facilitates this.
Especially because despite this and the willingness of athletes to embrace recovery, athletes are often under fueling their recovery still The Why: When exercising, we are breaking down muscles and using our fuel stores.
But why does the body need to quickly go into an anabolic state? This is because the primary importance after exercise is glycogen replenishment.
The When: The simple answer to this? Insulin independent phase of muscle glycogen synthesis: In the initial post-exercise phase, there is a rapid increase in glycogen synthesis for mins. Insulin dependent phase of glycogen synthesis: The second phase of glycogen synthesis has been defined as the insulin-dependent phase.
Figure 1: Glycogen resynthesis is increased with carbohydrate ingestion in the immediate post exercise window What: Protein and carbohydrates work together in the post exercise window, allowing for improved protein metabolism as well as improved glycogen synthesis when compared to carbohydrates alone.
How Much: Your carbohydrate requirements are at least in part related to your intake prior and during training — in your Prime and Perform windows.
Protein requirements are as follows: 0. Protein per meal should be between 0. If this is the case and recovery time is less than 4 hours, you may consider the following right after your workout: 1.
This may not always be logistically possible or appropriate, given training time, goals etc. Refueling Conclusions and Recommendations The good news is that your post training session social meal might be the perfect recovery protocol even perhaps with the addition of a good coffee.

Urine color should be clear, and there should be a plentiful amount. Coaches can keep track of fluid losses by weighing athletes before and after training. For every pound of fluid lost, athletes should consume 20 to 24 oz of fluid. Moreover, postworkout fluids or meals should contain sodium, particularly for athletes who lose large amounts of sodium through sweat.
Repair and Build In addition to fluid and electrolyte losses, training increases circulating catabolic hormones to facilitate the breakdown of glycogen and fat for fuel. These hormone levels remain high after exercise and continue to break down muscle tissue.
Without nutrient intake, this catabolic cascade continues for hours postexercise, contributing to muscle soreness and possibly compromising training adaptations and subsequent performance.
To repair and build muscle, athletes must refuel with high-protein foods immediately following exercise, especially after resistance training. They should consume 20 to 40 g of protein that includes 3 to 4 g of leucine per serving to increase muscle protein synthesis. In addition, whey is an optimal postworkout protein because of its amino acid composition and the speed of amino acid release into the bloodstream.
What many athletes often overlook is the importance of carbohydrate intake for building and repairing muscle. Carbohydrate can decrease muscle protein breakdown by stimulating insulin release.
Resistance training athletes benefit from consuming carbohydrates and protein after strenuous workouts. Attenuating Excess Inflammation Athletes who get the required amounts of leucine-rich protein and carbohydrate immediately after exercise turn that crucial time period from a catabolic state to an anabolic state.
To help curb excessive inflammation and muscle soreness, researchers have examined various products and ingredients. In particular, tart cherry juice and ginger fresh or heat treated have been found to decrease eccentric-exercise—induced inflammation and delayed onset muscle soreness.
Specific Considerations While recovery nutrition has three primary goals, the manner in which these goals are achieved depends on the type of sport an athlete plays. Based on sports science research, nutrition recommendations for athletes are divided into two categories: endurance sports and resistance training.
A sports dietitian can develop individualized plans for each athlete, keeping in mind that plans may change based on training adaptations, changes in growth and body composition, injuries, illness, and training phase.
We educate them on their postlift needs during their individual nutrition consults. Many eat dinner postpractice at our training table or at the dining hall where a dietitian is available for live plate coaching as well. Importance of Sports Dietitians Sports dietitians play an essential role in helping athletes recover from training.

After intense workouts, athletes are physically depleted, dehydrated, and mentally exhausted. Therefore, recovery nutrition must have three primary goals: refuel, rehydrate, and repair and build. Replenishing vital nutrients, rehydrating and restoring electrolyte balance, repairing damaged muscle tissue, and attenuating excessive inflammation accomplish these goals.
