Sports Nutrition Guide for Athletes

Pre-workout meals should combine easily digestible carbohydrates with moderate protein consumed 2-3 hours before exercise. Good options include oatmeal with banana and almond butter, rice with chicken, whole grain toast with peanut butter, or Greek yogurt with granola. For closer to workout time (30-45 minutes), lighter options like a banana, sports drink, or energy bar work well. The goal is to provide glycogen for fuel and stable blood sugar without causing gastrointestinal discomfort. Individual tolerance varies, so experiment to find what works best for your body and training type.

Supplements are not strictly necessary if you maintain a well-balanced diet with adequate calories, protein, carbohydrates, and micronutrients. However, certain supplements have strong evidence for supporting athletic performance, including whey protein for muscle recovery, creatine monohydrate for strength and power, beta-alanine for high-intensity exercise, and caffeine for endurance. Supplements should complement—not replace—solid nutrition fundamentals. Focus first on whole foods, consistent training, and adequate sleep, then consider supplements that align with your specific performance goals and sport.

For activities lasting over 60 minutes, drink 500-1000 mL of fluid containing 4-8% carbohydrates and electrolytes per hour. Sports drinks with sodium help with fluid retention and maintain electrolyte balance better than water alone. Start hydrating early—drink about 400-600 mL of fluid 2-3 hours before exercise, then 200-300 mL 15-20 minutes before activity starts. During exercise, consume 150-250 mL every 15-20 minutes depending on sweat rate and conditions. Post-exercise, rehydrate with 150% of fluid lost (weigh yourself before and after) over 4-6 hours. Individual sweat rates vary significantly, so practice your hydration strategy during training before competition.

Consume a meal within 1-2 hours post-workout containing 0.25-0.30 g protein per kilogram of body weight and 1.0-1.2 g carbohydrates per kilogram to optimize muscle protein synthesis and glycogen replenishment. Excellent post-workout options include grilled chicken with sweet potato and vegetables, Greek yogurt with berries and granola, tuna sandwich on whole grain bread, or a protein smoothie with banana and oats. Include both protein and carbohydrates for maximum recovery benefits. If a solid meal isn't available, a protein shake with fruit serves as an effective interim solution. Rehydration with electrolyte-containing beverages is equally important, especially after intense or long duration exercise.
