Athletes Need to Know About Nutrient Timing

The significance of nutrient timing: when and how to fuel your training for maximum results As an athlete, you expect nothing less than the best from your body. Performance is crucial, and every advantage counts. No matter how insignificant.

So, what if you could increase your endurance and strength, delay fatigue, and even improve your recovery without changing your diet or training routine? Wouldn't you be all over it? There is, in fact. It all comes down to nutrient timing. Because it's not just a question of what to eat to fuel your training, but also when.We'll show you how to improve your performance on the track, in the ring, or in the gym by strategically manipulating your food and supplement intake.


What is the definition of nutrient timing?

To get the most out of your body, you must properly fuel it. This entails a steady stream of proteins, whole grains, fruits, and vegetables into your cells. Calorie intake supports activity levels, and eating wholesome, nutritious foods will assist you in achieving your performance objectives. However, nutrient timing has less to do with what you eat and more to do with when you eat it.

Nutrient timing includes the use of methodical planning and eating of whole foods, fortified foods, and dietary supplements, according to a recent position statement from the International Society of Sports Nutrition (ISSN).

Simply put, you can improve performance, recovery, and muscle tissue repair by timing your food intake and manipulating the macronutrient ratio. There's also a significant psychological component to it. Nutrient timing proponents claim that it can improve mood and energy levels.

Since the 1980s, nutrient timing has been used. Researchers discovered that adjusting carbohydrate intake around exercise increased muscle glycogen stores and improved physical performance during time trials.

Around the same time, researchers discovered that increasing carbohydrate intake immediately after exercise improved glycogen synthesis rates, which is an important part of the recovery process. Nutritionists, performance coaches, and researchers have spent hours analyzing the timed effects of various nutrients and supplements on exercise performance since these innovations.


What is the significance of nutrient timing?

The foundations of athletic success are fundamentals. Your performance will improve as you adapt to training and support your activity levels with the right foods. However, after a while, you'll need another strategy layered on top to really push your progress.

This is here the importance of nutrient timing comes into play.

It's important to keep in mind that nutrient timing is intended for athletes who have already achieved a high level of physical fitness. Also, they should eat a healthy diet that will help them maintain their body composition and athletic performance.

In other words, those who have already nailed their calories and macros will benefit from nutrient timing. If the nutrients you're taking aren't going to help you progress, there's no point in timing them. Athletes with primed physiques can use nutrient timing techniques to gain a competitive advantage.

If you're just getting started on the road to better athletic performance, start with a focus on overall energy intake and exercise. As you progress, incorporate timing manipulation.


It's not just about what, but also about when.

We now know that nutrient timing provides several key benefits as time has passed and research has progressed:

  • Enhanced exercise adaptation
  • Repair and recovery are improved.
  • Improved performance due to increased work capacity.

A healthy, performance-optimized diet includes energy balance and food choices. However, evidence suggests that timing is also important. Because the way your body uses nutrients varies depending on when they are consumed.


The findings of the carbohydrate nutrient timing study

Glycogen storage is used to fuel training, competitions, and workouts that last more than 60 minutes or include multiple bouts of high-intensity exercise. As a result, it's critical to devise strategies to help maximize the amount of glycogen stored in the muscle and liver. Of course, a carbohydrate-rich diet is essential, but new research suggests that timing carb ingestion is crucial for maximizing overall effects.

While strength and team sport athletes require optimal glycogen stores to improve performance, endurance athletes have dominated the research into carbohydrate nutrient timing.


Carbohydrate loading can help athletes increase their glycogen stores.

Coaches have used a technique known as carb-loading to maximize intramuscular glycogen3 since the late 1970s. The technique varies from athlete to athlete (and sport to sport), but the most common carb-loading strategy is a seven-day plan:

  • 3–4 days of high-volume training with a low-carbohydrate diet
  • After that, a 'loading phase' of 3-4 days (consuming 8-10 grams per kilo of body weight) is followed by a decrease in training.

This model has a few variations as well. The classic 6-day version is included, as well as a 3-day variation in which carbohydrate intake is increased but no exercise is included during the loading phase. There's even a one-day version that entails resting while eating a lot of carbs.

This method has been shown to result in much higher levels of glycogen supersaturation than a traditional high carb diet. The goal is to deplete glycogen stores by following a low-carb diet and engaging in high-volume training. Then force muscle cells to compensate for their glycogen storage by increasing it.

Carb loading, when combined with an effective tapering phase prior to competition, has been shown to improve long-distance running performance in well-trained athletes5. Female athletes may need to increase their calorie and carb intake to maximize the super-compensatory effect6, according to research. This is due to physiological differences alone.


Fatigue is delayed, and endurance is increased.

It's also been shown to help with fatigue during long-distance endurance training7. This is thought to be due to increased glycogen stores, which not only provide more substrate energy but also reduce non-working muscle indirect oxidation (via lactate).

Carbohydrate loading appears to be effective only in trained athletes, as glycogen supercompensation does not occur as well in untrained people. In fact, trained athletes can compensate without the low-carb phase, providing justification for a more'modified' carb-loading strategy.

Carb-loading strategies include high-glycemic carbs during the loading phase, which helps to increase carb intake while limiting fiber intake (high fiber will lead to bloating and discomfort). To avoid unwanted side effects, it's important to stick to familiar foods.


Foods to concentrate on include:

  • Pasta and white bread
  • Potatoes
  • Sports drinks and juice
  • Applesauce, candy, and cakes
  • Fruit
  • Pre-workout carbs can help both strength and endurance athletes.

Carbohydrate loading or high-intensity training on the days leading up to a competition is one strategy for improving athletic performance. Another option is to increase carb intake in the hours leading up to the event.

When consumed four hours before exercise, high-carb meals have been shown to improve cycling work rate by increasing glycogen synthesis8. Despite the fact that the meal had been fully digested prior to exercise, glycogen storage increased by 42%. Due to gastric load and potential negative effects such as rebound hypoglycemia, eating a high-carb meal in the hour before exercise is not recommended.


Strength athletes have experienced similar results.

Weightlifters who did high-volume strength workouts benefited from carb supplementation before, during, and after each workout, according to a study published in the Journal of Strength and Conditioning Research.

Because intermittent activities rely on anaerobic glycolysis for fuel, the authors suggested that adequate glycogen stores be built up prior to exercise to maximize performance.

Instead, eat high-carb snacks, supplements, or smaller meals, and drink plenty of water to stay hydrated. Many athletes use carb-based supplements to fuel up before a workout. This is because glycogen synthesis is similar to that of food10, 11 but with fewer possible side effects.


Carbohydrates replenish energy and aid recovery after a workout.

The primary goal following a training session or competition is to aid recovery. Carbohydrate intake is undoubtedly a driving force behind this process, as replenishing glycogen levels is a top priority for all athletes. Glycogen stores could be replenished in half the time if a large dose of carbohydrate was consumed within 30 minutes after a workout14, according to early research.

Several studies since then have found similar results. Ingesting between 0.5 and 1 gram of carbohydrates per kilogram of body weight within a 30-minute post-exercise window appears to be the most effective strategy for replenishing energy stores. Additionally, if the athlete consumes more than 8 grams of carbs per kilogram of body weight, glycogen can be completely replenished in just 24 hours.

In any of the three scenarios below, an athlete's post-workout carb intake should be a top priority:

  • Someone who needs quick glycogen replenishment
  • One who has engaged in glycogen-depleting exercise or who has received insufficient carbohydrate pre-workout.

Last Word

It's not just about what you eat, but also about when you eat it.

Athletes who want to improve their performance and recovery can benefit from nutrient timing.

Depletion of muscle glycogen can result in poor performance and have a negative impact on muscle repair. This is where carbohydrate loading in the days leading up to exercise, as well as strategic carb intake in the hours following, can drastically improve strength, endurance, and recovery.
