Anaerobic Nutrition | Power Moves Guide

Fuel short, hard efforts with fast carbs, buffers, creatine, and smart timing tailored to sprint and strength sessions.

What “Anaerobic” Really Means For Fuel

Short, high-power efforts pull from two engines: the phosphagen system and fast glycolysis. The first covers five to ten seconds of all-out work with stored ATP and phosphocreatine. The second uses muscle glycogen to push efforts that last from roughly ten seconds to two minutes. When you train in this zone, fuel choices should make those engines fire quickly and repeat cleanly between sets.

The headline moves are simple: steady carbs in the days before, a small carb hit near training, daily creatine, and smart use of caffeine and buffers. Fluids and sodium keep the output steady across repeats. Protein protects muscle when the session piles on.

Anaerobic Fueling Plan: From Day Before To Post-Session

Day-Before Setup

Keep carbohydrate intake moderate to high so muscle glycogen is ready. Many athletes land well at 4–7 g/kg/day during hard blocks, scaling with total training time. Protein can spread across the day at 0.3–0.4 g/kg per meal. Fats fill the rest without crowding carbs.

Pre-Session (60–15 Minutes)

Pick something easy to digest. Aim for 20–45 g of carbohydrate if your stomach agrees. That can be fruit, rice cakes, a small bar, or a drink mix. If you like caffeine, pick a dose from 2–3 mg/kg taken 30–60 minutes before the first set. Sensitive lifters can slide lower to keep jitters away.

During Repeats

Most pure sprint or heavy sets won’t need extra fuel during the hour, but mixed intervals can feel better with 20–30 g of carbohydrate sipped across the session. Small mouthfuls beat a single slug when rest periods are short.

Post-Session Window

Hit protein in the first two hours, aiming for 0.25–0.4 g/kg from food or a shake. Pair it with 0.8–1.2 g/kg carbohydrate over the next few hours if another hard day is coming. Add creatine any time of day that you will remember.

Big Levers Table: What To Use And When

Lever	Why It Helps	Practical Use
Carbohydrate	Feeds fast glycolysis for repeats	4–7 g/kg/day; 20–45 g in the hour before
Creatine	Restores phosphocreatine between sets	3–5 g/day with meals; optional 20 g/day load for 5–7 days
Caffeine	Lowers effort, sharpens power output	2–3 mg/kg 30–60 min pre; adjust to tolerance
β-alanine	Raises muscle carnosine for buffering	3.2–6.4 g/day split doses for ≥4 weeks
Sodium Bicarbonate	Buffers acid in repeated high-power bouts	0.2–0.3 g/kg 60–180 min pre; test gut first
Protein	Supports repair and strength gains	0.25–0.4 g/kg within 2 h; hit daily total 1.6–2.2 g/kg
Fluids & Sodium	Preserves output across sets	Start hydrated; sip to thirst; add salt if sweat is heavy

Evidence Snapshot: What’s Backed And What’s Hype

Carbohydrate remains the backbone for short, hard sessions that last beyond a single burst. The joint position paper from sports dietitian groups and ACSM points to performance gains when carbohydrate supports training volume and intensity. Caffeine has consistent effects on power and effort at moderate doses. Creatine is the most studied tool for quick bouts and strength work. β-alanine and sodium bicarbonate help sessions where burning legs limit output, such as 30–120 second repeats. Read the ACSM position paper for the broader framework, and check the NIH ODS performance supplement sheet for ingredient-level detail.

Pre-workout blends often mix caffeine, amino acids, and buffers. Scan labels for total caffeine per serving and check for third-party testing when you compete under rules.

How To Stack The Pieces On Training Days

Heavy Strength Session

Eat a normal meal two to three hours pre with protein and a starch. Add a small carb top-up 30–60 minutes pre if lifts need snap. Daily creatine does the quiet work here. A moderate caffeine dose can help hard sets, but sleep still wins over chugging late in the day.

Sprint Session

Keep fiber and fat lower near the start time. A small carb snack and a moderate caffeine dose pair well. For athletes who respond to sodium bicarbonate without gut issues, plan the dose well ahead of the first rep so restrooms are not the main event.

Mixed Intervals Or Circuits

These sessions tax both engines. A drink with 20–30 g carbohydrate during rest periods keeps output even. If repeats last one to two minutes, a loaded β-alanine plan can extend work at the same perceived effort.

The plan hinges on carbs, creatine, caffeine, and buffers used at the right times. That may sound simple, but the order and dose matter. Start with food, then layer the well-studied aids if they fit your goals and schedule.

Hydration And Sodium: Small Tweaks, Real Payoff

Power drops fast when dehydration creeps in. Start sessions already topped up. Urine pale is a decent field check. In hot, sweaty blocks, add salt to meals and drinks. Some athletes aim for 300–600 mg sodium per 500 ml during long track sets or long gym blocks with conditioning work.

Safety, Side Effects, And Testing

Caffeine can disturb sleep, raise heart rate, and feel edgy at higher doses. Start lower, and don’t chase big numbers near bedtime. Sodium bicarbonate can upset the gut; split doses with water and test on a light day first. β-alanine can cause skin tingles; smaller servings spread across the day blunt that effect.

Pick products that carry third-party seals if you compete. Read labels for total caffeine across all sources, including coffee, gels, and drinks. Keep a simple log of dose, timing, and how you felt. That log becomes your playbook for the next training block.

Menu Ideas That Match The Plan

Easy Pre-Lift Picks

Greek yogurt with honey; rice cakes with jam; a banana and whey in milk; cereal with milk; toast with thin peanut butter and sliced fruit. Light and familiar beats fancy when the clock is tight.

Between Sets Or During Repeats

Sports drink sips; a soft chew; watered juice with a pinch of salt. Keep portions small so you can move.

After The Work

Steak and potatoes; egg burrito; rice bowl with chicken; cottage cheese and fruit; tofu stir-fry with rice. Pair protein with a carb you enjoy and that sits well.

Supplement Cheat Sheet (Evidence-Led)

Supplement	Proven Dose	Best Use
Creatine Monohydrate	3–5 g/day; optional 20 g/day for 5–7 days then 3–5 g/day	Strength, repeated sprints, lean mass
β-alanine	3.2–6.4 g/day split doses for ≥4 weeks	Repeats lasting 30–120 seconds
Sodium Bicarbonate	0.2–0.3 g/kg 60–180 min pre; or split micro-doses	High-intensity repeats; test tolerance
Caffeine	2–6 mg/kg 30–60 min pre	Power output and perceived effort
Nitrates	300–600 mg nitrate 2–3 h pre	Borderline for pure sprints; better for longer work
Protein	0.25–0.4 g/kg post; 1.6–2.2 g/kg/day	Strength and recovery

Putting It All Together

Pick two or three moves that fit your sport and life. Build around carbs and protein you like. Layer creatine daily if strength or repeats matter. Add a moderate caffeine dose when timing fits. Use buffers only if the session type demands them and you’ve tested them on a practice day. Keep a short list of foods and drinks that sit well, and pack them so you aren’t guessing on the day.

One last tip: plan sleep and caffeine like a pair. Great sessions come from freshness, not just stimulants. If the choice comes down to a late dose or a solid night, bank the night. Training blocks add up, and nothing beats a string of steady days.
