For competitive athletes, basketball players, volleyballers, and strength-speed coaches who want a higher vertical jump but feel stuck — frustrated by inconsistent gains, slow recovery, or training that doesn't translate to game-day explosiveness — this guide breaks down the exact nutrition moves that support power, not just bodyweight. You're juggling practice, lifts, and games; our sports nutrition team helps translate science into simple meal plans and timing strategies so your diet actually adds inches to your jump, not confusion to your schedule.
How does nutrition affect vertical jump and athletic performance?
Nutrition is the fuel and repair system behind every jump. Power production depends on fast-twitch muscle recruitment, nervous-system readiness, and muscle glycogen levels. Eat poorly and one of those systems falters — even if your squat numbers are good. From what I've seen, the athletes who improve fastest combine targeted training with nutrient timing and adequate protein (not just random eating).
Quick facts:
- Glycogen fuels high-intensity sets and plyometrics (so carbs matter).
- Protein rebuilds and increases contractile capacity (so you regain force faster).
- Hydration and electrolytes support nerve conduction — that snap in the ankle rollover? It's electrical.
What should I eat before a vertical-jump training session?
Short answer: fast-digesting carbs + moderate protein + low fat about 60 minutes before hard work. Why? Because carbs top up muscle glycogen and the protein helps limit muscle breakdown — that's the combo that lets you hit maximal effort repeatedly.
Practical pre-workout template
Consume 60 grams of carbohydrates and 20 grams of protein about 45–60 minutes before training. Example: 1 cup of cooked white rice (45g carbs) + 1 scoop whey (20g protein) + 1 small banana (15g carbs). Keep fats low so digestion doesn't slow you down.
How soon after training should I eat for the best recovery?
Eat soon. Really soon. Aim for 30 minutes after finishing plyometrics or strength sessions.
Post-workout targets
- Protein: 40 grams (fast-absorbing whey or a lean solid — chicken or turkey is fine).
- Carbs: 90 grams (to refill glycogen and support repeated high-intensity efforts later).
- Fluid: 500 ml of water plus a pinch of salt (electrolytes matter when you sweat a lot).
Why those numbers? Because rebuilding muscle proteins and restoring glycogen quickly means your next session isn't handicapped. I think of the post-workout meal like reinserting bullets into the magazine — do it fast so you can keep firing.
What daily diet supports improved vertical jump (macros and calories)?
Here's a working example for an 80 kilogram athlete doing regular explosive training.
- Calories: 3,000 kcal per day (this supports performance and lean mass maintenance during explosive training).
- Protein: 180 grams per day (that's 2.25 grams per kilogram — enough to support muscle repair and neuromuscular adaptations).
- Carbohydrates: 360 grams per day (high-intensity power demands glycogen; carbs are not optional for jump-focused athletes).
- Fat: 83 grams per day (for hormones and sustained energy).
So here's the deal — those numbers are specific and purposeful. If you're 70 kg or 90 kg, scale intake proportionally or get a coach to do the math. But don't skimp on carbs thinking 'I'll just lift heavier' — that often backfires.
Which supplements help vertical jump and recovery?
Supplements won't replace training, but they can amplify results when used correctly. From my experience with athletes, a handful consistently deliver ROI.
- Creatine monohydrate: 5 grams daily. Better power output, faster recovery between sprints and jumps.
- Caffeine: 3 mg per kilogram bodyweight 45 minutes before competition or a testing day (so 240 mg for an 80 kg athlete). Use cautiously—test in practice first.
- Beetroot/nitrate: 300 ml beetroot juice about 2–3 hours before training can improve muscle efficiency for repeated efforts.
- Whey protein: 25–40 grams post-workout to hit that 40g target quickly (mixes well, digests fast).
Don't buy every powder you see. Focus on creatine, caffeine (strategically), and quality protein first. The rest is icing.
How should you time meals across a training day (periodization)?
Meal timing should mirror your training pattern. If you have two sessions, one heavy lift in the morning and a plyo session in the afternoon, split carbs to fuel both.
- Morning heavy strength: carb-rich breakfast (90g carbs) + 30g protein before session.
- Post-strength: full recovery meal (40g protein, 90g carbs).
- Afternoon plyo session: small carb snack 45 minutes prior (30–60g carbs).
- Evening: protein-focused dinner with moderate carbs and fats for hormonal support.
Preseason? Eat slightly more carbs and calories to support high volume. In-season? Prioritize quick recovery between games — carbs and electrolytes will save you more than another isolation exercise ever will.
Sample 1-day meal plan for an 80 kg vertical-jump athlete
Everything listed below is practical, packable, and proven to support power and recovery.
- Breakfast (7:00): 1.5 cups cooked oats (90g carbs), 1 scoop whey (25g protein), 1 tbsp honey — 700 kcal.
- Pre-training snack (10:00): 1 banana + 2 rice cakes + 1 small yogurt — 300 kcal.
- Training (11:00): plyometrics + strength session.
- Post-workout (12:00): smoothie — 1.5 cups cooked rice or 2 slices sourdough (90g carbs), 40g whey (40g protein), 500 ml water with pinch of salt — 700 kcal.
- Lunch (14:00): grilled chicken breast 200g (60g protein), 1.5 cups quinoa (90g carbs), mixed veggies — 700 kcal.
- Snack (17:00): cottage cheese 200g (24g protein) + apple — 300 kcal.
- Dinner (19:00): salmon 150g (35g protein, fats), sweet potato 300g (60g carbs), salad — 500 kcal.
- Evening snack (21:00): casein or Greek yogurt (25g protein) — 200 kcal.
Total: approximately 3,400 kcal, 180–200g protein, 360–380g carbs. Adjust total calories down to 3,000 if you're not gaining body mass.
Common nutrition mistakes that blunt jump gains
- Underfueling on heavy training days — you'll feel flat and produce less force.
- Ignoring post-session carbs — long-term power declines when glycogen is chronically low.
- Counting only calories, not timing — even a perfect calorie total fails if you're depleted in the workout.
- Over-relying on caffeine every day — tolerance builds and benefits decline (use for tests/matches).
- Chasing novelty supplements instead of basics (protein + creatine + carbs) — the simple stuff is powerful.

Frequently Asked Questions
Do I need to lose weight to jump higher?
Not necessarily. Losing non-functional mass (excess fat) can improve relative power, but losing muscle will hurt your vertical. Focus on recomposition: maintain or increase lean mass while dropping excess fat through a slight calorie deficit, high protein (180g per day for an 80 kg athlete), and preserved strength training.
How much protein is too much for jump gains?
There's a point of diminishing returns. For power athletes, around 2.0–2.3 grams per kilogram daily is effective (for an 80 kg athlete that's 160–184 grams). Going massively higher rarely gives extra jump-specific benefits and can complicate meal planning.
Will cardio ruin my vertical jump?
No — but long, steady-state cardio can interfere if it displaces strength and power training. Short, intense intervals are better for conditioning without destroying your power output. So keep conditioning specific and limited on hard lifting days.
How fast will my vertical jump improve if I change my diet?
You'll often see performance improvements in 2–4 weeks (better training quality, faster recovery), with measurable jump gains in 6–12 weeks when combined with an appropriate training program. Nutrition speeds adaptation — it doesn't replace consistent, explosive training.
Which foods should I avoid before testing vertical jump?
Avoid high-fat and very high-fiber meals right before testing — they slow digestion and can leave you feeling sluggish. Also avoid trying new supplements or stimulants on test day. Stick to familiar foods that you know digest well within 60 minutes.
