Adding PRO to create a CHO:PRO ratio of 3 — may increase endurance performance and maximally promotes glycogen re-synthesis during acute and subsequent bouts of endurance exercise.Nutrient timing for workouts -
For these individuals, what and how much they eat is the most important thing. While nutrient timing isn't critical to the average person, its importance must not be underestimated in the athlete including team sport athletes, endurance athletes, and weight trainers.
In the book, " Nutrient Timing " a book I also contributed to , Drs. John Ivy and Robert Portman make a great comment about the current state of sports nutrition practice.
higher energy needs and the benefits of additional protein ingestion , a "bulk nutrition" concept was adopted in which athletes began to believe things like "if protein is good, then more protein must be better. In other words, when many athletes find out that something is "good," they try to get lots of it.
And when many athletes find out that something is "bad," they try to avoid it at all costs. Unfortunately this is nothing more than a combination of the how-much-to-eat and what-to-eat approaches discussed above.
Combine that with a naive good vs. bad approach to food and you've got a recipe for sub-optimal nutritional intake. After all, few foods are always good or always bad well, I can think of a few?
This is certainly unfortunate for two reasons. First, much of the current science points to the fact that if you train regularly, the body is primed for fat gain or fat loss just as it's primed for muscle gain or muscle loss during specific times of the day.
Add in the wrong foods at the wrong times and you sabotage your efforts in the gym. Add the right foods and your efforts are given a giant boost. Secondly, although some foods are not optimal during certain times of the day i.
sugar , some of these same foods can actually be beneficial during other times of the day such as the post-workout period. Throwing aside the oversimplification inherent in the bulk nutrition concept, let's now get down to the nuts and bolts of optimal nutrient timing. Since I was a consultant in the development of the book, I'm going to go ahead and take the liberty of borrowing from some of Drs.
Ivy and Portman's nomenclature. In the book, the authors refer to three critical times of the day in which nutrient timing takes on a greater importance.
These times are known as the Energy Phase, The Anabolic Phase, and The Growth Phase. Since I like these distinctions, I'll use them here.
However, I'll add another phase that I call, somewhat in jest, The Rest of The Day Phase. The Energy Phase is called this because this phase occurs during the workout when energy demands are highest.
As you probably know, the energy used by skeletal muscle is ATP. This ATP is formed and resynthesized by macronutrients from the diet so carbs, proteins, and fats contribute indirectly to the energy of muscle contraction.
This breakdown of nutrients, while completely necessary, is, by definition, catabolic. As such, the workout period, as I've addressed in the past see Precision Nutrition - next week , is marked by a number of anabolic and catabolic effects.
Since this drink not only enhances blood flow but stocks that blood up with amino acids and glucose, the protein balance of the muscle will be shifted toward the positive and glycogen depletion will be significantly reduced.
In addition, those amino acids and glucose units, independent of their effects on muscle protein and glycogen status, can also lead to a decrease in cortisol concentrations and improve the overall immune response part of the acute phase response listed above and described in detail in the Precision Nutrition article.
Of course, if the aforementioned supplement is in a liquid form and is sipped during the exercise bout as recommended , dehydration, a potent performance killer in both strength and endurance athletes, can be staved off as well.
When examining the science of nutrient timing in detail, it becomes clear that one of the key "when to eat" times of the day is during the Energy Phase or during the workout. Of course, in focusing on when to eat, I'm in no way suggesting we should neglect considering what and how much to eat.
In fact, they're probably your next two questions so let's get to them right away. As indicated above, during the Energy Phase it's important to ingest some protein and carbohydrate. In my experience the easiest way to do this is to drink an easily digested liquid carbohydrate and protein drink.
Dilution is important, especially if you are an endurance athlete or if you're training in a hot environment. If you don't dilute your drink appropriately, you may not replenish your body's water stores at an optimal rate 9; Now that we know when to eat and what to eat, let's figure out how much.
Unfortunately this isn't as easy to answer. How much to eat really has a lot to do with how much energy you're expending during the exercise bout, how much you're eating the rest of the day, whether your primary interest is gaining muscle mass or losing fat mass, and a number of other factors.
For a simple answer, however, I suggest starting out by sipping 0. Meals that are high in protein, fat or fiber and concentrated meals stay in the stomach longer and therefore absorb more slowly. Carbohydrates, liquids and semi-solid foods leave the stomach relatively quickly and absorb more rapidly.
Enzymes are proteins that speed up reactions in the body and are essential components to digestion as well as exercise metabolism.
Physical activity triggers a number of reactions in the body and activates enzymes such as glycogen phosphorylase and glycogen synthase, which are responsible for turning glucose blood sugar into glycogen stored carbohydrate.
These enzymes remain active in the muscles for 30 to 60 minutes following exercise, and fuel consumed within this window can restore glycogen twice as fast as a meal consumed two hours later. The aforementioned anabolic window is a result of heightened enzyme activity following a workout.
During this time frame, your body is more likely to turn your shake or food into carbohydrate both in the muscles and liver rather than fat. Intense or long-duration exercise depletes muscle glycogen and breaks down muscle tissue protein.
Therefore, the goal of post-exercise fueling is to replace muscle glycogen and begin regenerating muscle tissue. Adequate carbohydrate and protein feeding post-exercise helps restore glycogen and protein stores, respectively.
An important consideration, however, is how long it takes to utilize the energy we consume; carbohydrate can digest, absorb and subsequently raise blood glucose within 15 to 30 minutes.
Protein, on the other hand, digests more slowly and does not lead to peak amino acid levels in the blood for up to three hours.
Thus, consuming protein two to three hours before the end of your workout one to two hours prior, in most cases could result in more rapid tissue regeneration post-workout. But protein still plays an important role post-exercise, as it helps carbohydrate with its role.
The addition of protein to carbohydrate increases insulin production. Insulin is a hormone that facilitates the uptake and storage of carbohydrates and amino acids read more about hormones here.
Thus, you can restore glycogen more quickly and prepare for your next workout, when you consume a combination of carbohydrate and protein and for the record, a few grams of fat does not delay absorption significantly.
A recent trend in fitness and athletics is a push for real food instead of pills, powders and bars. Supplement manufacturers lead you to believe that liquid calories are superior to solid foods because they are absorbed more rapidly.
And in a laboratory setting, this may be the case. But the only reason to use a supplement over a food is convenience. Few of us have live-in chefs and all of us have busy schedules, so quite often carrying a bar or shaker bottle are the only viable options.
When you do have the opportunity to prepare a meal, the extra digestion time compared to a shake will not hinder glycogen or protein resynthesis.
In fact lean meats, fruits, vegetables and whole grains have the benefit of more vitamins, minerals and antioxidants than the contents of your shaker bottle and may be considerably less expensive.
Transportable food options such as chocolate milk, fruit, yogurt, trail mix, homemade energy bars and sandwiches may provide the best of both worlds. As whole foods, they are nutrient dense and unprocessed, yet easy to take to the office or gym.
High-water foods such as melons, apples, pears, cucumbers and bell peppers provide the benefit of assisting with re-hydration as well but you still need to drink water before, during, and after exercise.
A quick note regarding chocolate milk, which some tout as the best post-workout option. Low-fat chocolate milk has a great ratio of macronutrients, provides vitamins and minerals and is incredibly cost-effective.
However, most of the research involving chocolate milk is flawed as it has been compared to lower-calorie drinks and it is no more or less effective than a similar drink or food providing the same amount of calories, carbohydrates and protein.
Your goals are an incredibly important consideration when making pre-, during, and post-workout food choices. Two different people, for example—one with weight-loss aspirations, one with healthy weight gain ambitions—should have two different fueling plans.
This leads to poor reaction time and slowness. Poor coordination as a result can lead to missteps, inattention, and injury. Additionally, chronic energy drain taking in fewer calories and nutrients than needed will increase your risk of overuse injuries over time.
Stress fractures are one example; poor tissue integrity can happen when athletes think solely about calories taken in but not the quality of the calories consumed. Inadequate protein will also hinder the rebuilding of damaged muscles during training.
If muscles are not completely repaired, they will not be as strong as they could be and will not function optimally. The damaged muscle fibers can lead to soft-tissue injuries. Both protein and carbohydrate along with certain nutrients are needed to help with this repair.
For instance, gummy bears may provide carbohydrate, but they don't contain any vitamin E, which is helpful in repairing soft-tissue damage that occurs daily during training. Therefore, the goal is both an appropriate quantity and an appropriate quality in food selection.

What Are the Benefits of Nutrient Timing? The Nutrient Timing Principles NTP help you do the following: Optimize fuel use so that you remain energized throughout your training Ensure that you repair and strengthen your muscles to the best of your genetic potential Ingest sufficient nutrients to keep you healthy and able to fight off infection, limiting the suppression of the immune system often experienced with intense training Recover from your training so that you are ready for your next practice, event, or training session with well-fueled muscles Energy When sports nutritionists talk about energy, we are referring to the potential energy food contains.
Recovery During the minutes and hours after exercise, your muscles are recovering from the work you just performed. Muscle Breakdown and Muscle Building Nutrient timing capitalizes on minimizing muscle tissue breakdown that occurs during and after training and maximizing the muscle repair and building process that occurs afterwards.
Immunity Nutrient timing can have a significant impact on immunity for athletes. Injury Prevention Did you know that dehydration and low blood sugar can actually increase your risk of injury?
