As athletes, you understand the vital role that nutrition plays in your performance. The food you consume fuels your training, recovery, and competition. However, the timing and content of your meals can dramatically impact your performance, especially in high-intensity sports like sprinting. In this article, we will explore the specific dietary needs of a sprinter during the pre-race hour, focusing on optimal macronutrient intake, including proteins, carbohydrates, and fats.
Carbohydrate Intake: Fueling High-Intensity Performance
In the hour leading up to a race, your body’s primary fuel source is carbohydrates. According to research published on PubMed, a high-carbohydrate diet can enhance performance during sprinting by maintaining high energy levels throughout the sprint^1^.

In anticipation of the high energy demand, it’s recommended that you consume a carbohydrate-rich meal or snack about 1-4 hours before your sprint. This ensures that your muscle and liver glycogen stores are fully stocked and ready to fuel your high-intensity efforts. Carbohydrates with a low to moderate glycemic index, such as whole grains, fruits, and vegetables, are the preferred choice, as they provide a steady release of energy.
However, remember to keep portions in check to avoid stomach discomfort during the sprint. High carbohydrate intake should be balanced with adequate hydration to facilitate nutrient absorption and prevent dehydration.

Protein Intake: Supporting Muscle Repair and Growth
Protein is an essential macronutrient for athletes, particularly those involved in activities requiring high power outputs such as sprinting. While protein isn’t a primary energy source during sprinting, it plays a crucial role in repairing and building the muscle tissue that’s broken down during intense physical activity.
A review in the Journal of the International Society of Sports Nutrition suggests that athletes should consume a small amount of high-quality protein prior to exercise to stimulate muscle protein synthesis^2^. Therefore, including a source of protein like lean meat, dairy, or a protein shake in your pre-race meal or snack can support your muscle health during the sprint.
Fat Intake: The Secondary Fuel Source
Unlike endurance athletes who heavily rely on fat as an energy source, sprinters predominantly depend on carbohydrates. However, that doesn’t mean that fats should be completely overlooked in your pre-race nutrition plan. Fats serve as a secondary energy source during prolonged exercise and play a key role in absorbing fat-soluble vitamins.
Healthy fats such as avocados, nuts and seeds, and oily fish can be incorporated into your pre-race meal a few hours before the event. However, as fats take longer to digest, they should be consumed in moderation to prevent any gastrointestinal discomfort during the sprint.
Hydration: Maintaining Fluid Balance
Hydration is just as important as macronutrient intake when it comes to your pre-race nutrition. Dehydration can impair your performance by increasing fatigue and reducing your body’s ability to regulate heat. According to the DOI, sprinters should aim to start the race in a well-hydrated state by consuming fluids regularly in the hours leading up to the event^3^.
Water is generally sufficient for hydration in sprint events. However, if the sprint is happening in hot conditions or if you tend to sweat heavily, you may consider an electrolyte-containing drink to replace the sodium lost in sweat.
In conclusion, a well-planned pre-race meal or snack that includes a balance of carbohydrates, protein, and fats, along with ample fluids, can provide the necessary energy and nutrients to optimize your sprint performance. Remember, every athlete is unique, and what works best for one person may not work for another. Therefore, it’s important to experiment with different foods and timings to see what suits you best.
Balancing Calories: Ensuring Adequate Energy Availability
Caloric balance is a crucial aspect of sports nutrition that sprinters should not overlook in their pre-race meal planning. Energy availability, defined as the amount of energy left for the body to use after accounting for the energy expended during training and competition, is essential for maintaining body weight and muscle mass which is crucial for a sprinter’s performance.
Sprinters, like all track and field athletes, need to consume enough calories to fuel their high intensity efforts and support their muscle mass. Insufficient caloric intake can lead to a decrease in muscle glycogen stores, which are the primary energy source for sprinting, and can negatively impact sprint performance.
According to a study in the Journal of Sports Medicine, sprinters should aim to consume around 30-60 grams of carbohydrates per hour in the 1-4 hours leading up to the race to maintain their muscle glycogen stores^4^. This roughly translates to 120-240 calories, depending on the individual’s body mass.
To balance their meal plan, sprinters should also include a moderate amount of protein and low fat. A study in the Journal of Sports Nutrition recommends around 0.25 grams of protein per kilogram of body weight and a small amount of low fat in the pre-race meal^5^.
Remember to adjust your caloric intake based on your specific needs, as influenced by your body weight, muscle mass, and the intensity of your sprint training.
Supplements: Enhancing Performance and Recovery
As a sprinter, sports supplements can be a useful addition to your pre-race meal plan to support your performance and recovery. Creatine, for example, is a widely used supplement in sprint training for its role in replenishing ATP, the primary energy source used in high intensity, short-duration activities like sprinting.
According to a study published in the Journal of Resistance Training, creatine supplementation can enhance sprint performance by increasing muscle power output^6^. Taking 3-5 grams of creatine monohydrate about an hour before the race can be effective.
Another beneficial supplement for sprinters is beta-alanine, which helps buffer the acid build-up in muscles during high intensity exercise. A systematic review in the Journal of Sports Medicine suggests that beta-alanine supplementation can delay the onset of muscular fatigue during short-duration, high-intensity activities^7^.
However, always remember to consult with a sports medicine professional or a certified sports nutritionist before starting any new supplement regimen.
Conclusion: Individualizing Your Pre-Race Nutrition
In the end, the key to optimal pre-race nutrition lies in individualization. Every sprinter is unique, with different body mass, muscle mass, fitness levels, and personal preferences. Thus, a one-size-fits-all approach does not apply when it comes to sports nutrition.
As a sprinter, you need to focus not just on what to eat, but also on when to eat and how much to eat. Your pre-race meal should include a balanced amount of carbohydrates to fuel your high intensity efforts, protein to support muscle repair and growth, and a small amount of fats for their role in energy provision and nutrient absorption.
Hydration should also be a primary focus, with adequate intake of fluids, preferably water or an electrolyte-containing drink if you are a heavy sweater or if the event is in hot conditions.
Lastly, consider adding sports supplements, like creatine and beta-alanine, to your pre-race meal plan to enhance your sprint performance and recovery. Always remember to consult with a sports medicine professional or a sports nutritionist to ensure you are using supplements safely and effectively.
Remember, your pre-race nutrition can make a significant difference in your sprint performance. Keep experimenting with different foods, meal timings, and supplements to find the meal plan that best supports your sprint training.
