Athletes and fitness enthusiasts are always looking for ways to improve their performance and achieve their goals.
Good nutrition can help your body perform better and recover faster after each workout.
Optimal nutrient intake prior to exercise will not only help you maximize your performance but also minimize muscle damage.
Fueling your body with the right nutrients prior to exercise will give you the energy and strength you need to perform better.
Each macronutrient has a specific role before a workout. However, the ratio in which you need to consume them varies by the individual and type of exercise.
Below is a brief look at the role of each macronutrient.
Your muscles use the glucose from carbs for fuel.
Glycogen is the way the body processes and stores glucose, mainly in the liver and muscles.
For short- and high-intensity exercise, your glycogen stores are your muscles' main source of energy.
But for longer exercises, the degree to which carbs are used depends on several factors. These include the intensity, type of training and your overall diet.
Your muscles' glycogen stores are limited. As these stores become depleted, your output and intensity diminish.
Studies have consistently shown that carbs can increase glycogen stores and utilization while boosting carb oxidation during exercise.
Carb loading, which involves consuming a high-carb diet for 1-7 days, is a well-known method to maximize glycogen stores.
Many studies have documented the potential of pre-workout protein consumption to improve athletic performance.
Eating protein (alone or with carbs) prior to exercise has been shown to increase muscle protein synthesis.
One study showed a positive anabolic response after participants consumed 20 grams of whey protein before exercise.
Other benefits of eating protein before exercise include:
A better anabolic response, or muscle growth
Improved muscle recovery
Increased strength and lean body mass
Increased muscle performance
While glycogen is used for short- and high-intensity bouts of exercise, fat is the source of fuel for longer and moderate-to-low-intensity exercise.
Some studies have investigated the effects of fat intake on athletic performance. However, these studies looked at high-fat diets over a long period, rather than prior to exercise.
For example, one study showed how a four-week diet consisting of 40% fat increased endurance running times in healthy, trained runners.
- The Timing of Your Pre-Workout Meal Is Key
The timing of your meal is also an important aspect of pre-exercise nutrition.
To maximize the results of your training, try to eat a complete meal containing carbs, protein and fat 2-3 hours before you exercise.
However, in some cases, you may not be able to get in a full meal 2-3 hours before working out.
In that case, then you can still eat a decent pre-workout meal. However, keep in mind that the sooner you eat before your workout, the smaller and simpler the meal should be.
If you eat 45-60 minutes prior to your workout, choose foods that are simple to digest and contain mainly carbs and some protein.
This will help prevent any stomach discomfort during exercise.
- Some Examples of Pre-Workout Meals
Which foods and how much to eat depends on the type, duration and intensity of the workout.
A good rule of thumb is to eat a mixture of carbs and protein prior to exercise.
If you eat fat with your pre-workout meal, then it should be consumed at least a few hours before your workout.
Here are some examples of balanced pre-workout meals:
1. If Your Workout Starts Within 2-3 Hours or More
Sandwich on whole-grain bread, lean protein and a side salad
Egg omelet and whole-grain toast topped with avocado spread and a cup of fruit
Lean protein, brown rice and roasted vegetables
2. If Your Workout Starts Within 2 Hours
Protein smoothie made with milk, protein powder, banana and mixed berries
Whole-grain cereal and milk
A cup of oatmeal topped with banana and sliced almonds
Natural almond butter and fruit preserve sandwich on whole-grain bread
3. If Your Workout Starts Within an Hour or Less
Greek yogurt and fruit
Nutrition bar with protein and wholesome ingredients
A piece of fruit, such as a banana, orange or apple
Keep in mind that you don't need to eat many pre-workout meals at different times. Just choose one of these.
For best results, experiment with different timings and nutrient compositions.
