Macronutrients for Athletic Performance: Fuel, Build, Thrive
Carbohydrates: The Prime Mover of Speed and Power
01
Muscles store glycogen that powers high-intensity efforts, and when it runs low, speed quickly fades. Most athletes thrive on 5–10 grams of carbohydrate per kilogram daily, scaled to training load, ensuring reserves stay robust for performance.
02
Simple carbs work brilliantly before and during intense sessions because they digest quickly and spare the gut. Complex carbs shine at meals farther from training, supporting steady energy, micronutrient variety, and fiber without compromising comfort or pace.
03
One runner hit a wall at kilometer seven, then grabbed a mid-race banana and revived within minutes. That quick glucose bump, plus a sip of sports drink, turned a fading effort into a personal best and a big post-race grin.
Fats: Endurance, Hormones, and Satiety
EPA and DHA may help manage post-exercise soreness and support adaptation, especially when training volume climbs. Many athletes aim for one to two grams combined EPA/DHA daily from fatty fish or supplements, coordinated with professional guidance and personal tolerances.
Fats: Endurance, Hormones, and Satiety
High-fat foods digest slowly, which can feel heavy before intense workouts. Keep pre-session meals lower in fat, shifting richer sources like salmon, olive oil, or nuts toward dinners and easy days, protecting both gut comfort and training quality.
Macro Timing and Periodization
Occasionally training with lower glycogen can sharpen metabolic flexibility, but it should be used sparingly and strategically. Save your highest carbohydrate availability for key quality sessions and competition, so you can express peak power and pace.
Building Performance Plates
On rest days, fill roughly a quarter of the plate with starches; on moderate days, increase to half; on hard days, lean toward even more. Vegetables, fruit, and lean proteins remain steady anchors that frame your carbohydrate adjustments.
Building Performance Plates
Team athletes need carb-rich pre-game meals, endurance athletes focus on steady carb flow and recovery, and strength athletes prioritize protein with supportive carbs. Each plate shifts macronutrient emphasis according to specific demands, schedule, and personal tolerance.
Monitoring and Adjusting: From Data to Plate
Wearables, RPE, and Energy Availability
Combine wearable estimates with session RPE and body signals to sense true energy needs. If hard days feel harder than expected, increasing carbohydrates first often restores pop, while consistent protein supports recovery and reduces nagging soreness.
Signs You Need More of a Macro
Dragging pace, frequent colds, and poor sleep may hint at inadequate carbohydrate or overall energy. Persistent soreness, brittle nails, or hair issues can suggest low protein or fat. Track patterns for weeks, not days, before adjusting thoughtfully.
