Fueling for Peak Performance

WHAT AND WHEN YOU EAT can make the difference between hitting a personal best or struggling through your sport. Understanding how to fuel your body before you begin is particularly essential. While all athletes benefit from a foundation of whole, nutrient-dense foods, pre-event fueling strategies should be tailored to the unique demands of each sport. Here are some examples.

Endurance sports such as running rely heavily on carbohydrates. Carbs are stored as glycogen in the muscles and liver, and they’re the primary energy source during long-distance efforts. A lack of glycogen can lead to fatigue, sluggishness and “hitting the wall.”

Pre-run fueling tips:

• Two to three hours before: Eat a meal rich in complex carbohydrates with moderate protein and low fat/fiber to avoid stomach distress. Think oatmeal with banana and a scoop of almond butter, or a turkey sandwich on whole grain bread.

• 30 to 60 minutes before: If running early or needing a quick top-up, go for a small, easily digestible carb such as a banana, energy gel or a slice of toast with honey.

Hydration is also critical. Drink water or a low-sugar electrolyte drink, especially if it’s hot.

Strength training requires explosive power and muscle repair. While carbs provide the energy for lifting sessions, protein helps preserve and rebuild muscle tissue.

Pre-lift fueling tips:

•One to two hours before: A balanced meal or snack with both carbs and protein works best. Examples include Greek yogurt with berries and granola, or chicken and sweet potatoes.


30 to 60 minutes before: A light snack such as a protein shake with a piece of fruit can help maintain energy and muscle synthesis during your workout.

Unlike endurance athletes, fat and fiber aren’t as problematic for pre-strength workouts, though large amounts may slow digestion if consumed too close to the session.

3. Swimmers: Timing and Digestibility Matter

Swimmers often train early in the morning or on a tight schedule which makes pre-workout nutrition a balancing act. Digestibility is key — no one wants to swim with
a heavy stomach.

Pre-swim fueling tips:


Two to three hours before: Time permitting, opt for
a moderate-sized meal with carbs, a little protein and minimal fat. Try a smoothie with banana, protein powder and oats.


30 to 60 minutes before: If you’re short on time, a small snack such as a granola bar or a rice cake with peanut butter can provide quick energy without sitting heavily in your stomach.

Hydration can be overlooked in water-based sports, but swimmers still sweat and need electrolytes. Sip water throughout your session.

4.
Racket Sports:
Fuel for Endurance and Reaction Time

Racket sports demand both aerobic endurance and fast-twitch muscle reactions. Long matches and heat exposure can deplete energy quickly, so fueling must support both sustained performance and mental sharpness.

Pre-match fueling tips:


Two to three hours before: Eat a meal high in carbs
with moderate protein. Whole grain pasta with grilled chicken and veggies, or a quinoa bowl with roasted
vegetables and tofu are great options.


30 to 60 minutes before: Snack on a banana, a handful of pretzels or a sports drink — simple carbs that provide quick fuel.

Staying hydrated is essential for mental clarity, reaction speed and muscle function, especially during long matches or outdoor play.

Bonus Tips for All Athletes


Avoid experimenting with new foods on game day or race morning. 


Listen to your body: Some athletes thrive on a full meal, while others need lighter options.


Include recovery nutrition post-event, ideally within 30 to 60 minutes. A mix of carbs and protein helps replenish glycogen stores and repair muscle tissue.


Plan ahead if you’re traveling or competing in the morning. Pack easy-to-digest foods such as fruit, energy bars or homemade muffins.

Different sports call for different fueling strategies, but the common thread is planning ahead and focusing on nutrient timing. By tailoring your nutrition to your activity, you give yourself the best shot at performing your best.
