I'll admit—for years, I told every surfer who walked into my clinic the same thing: "Hit 20-30 grams of protein within 30 minutes after your session." I bought into the whole anabolic window thing, especially for what I thought was endurance-dominant work. Then I started actually tracking surfers—real ocean athletes, not just gym rats—and the data slapped me in the face.
I had this one client, Jake—28, surfed 4-5 days a week in Santa Cruz. He was religious about his post-surf shake, but he kept complaining about shoulder fatigue that wouldn't quit and pop-ups that felt sluggish by his third session of the day. When we put a heart rate monitor and GPS on him during a 2-hour dawn patrol, we found he was burning 800-1,100 calories with heart rates spiking to 90% max during paddle battles. His protein timing was perfect, but his total daily intake was about 60 grams short of what his muscles actually needed to repair and adapt.
Look, your body doesn't read studies about bodybuilders. Surfing's this weird hybrid: endurance paddling with explosive pop-ups and constant stabilization. The research on pure endurance athletes or pure power athletes doesn't fully translate. So let's cut through the bro-science and look at what actually works for building paddling strength and recovering between sets.
Quick Facts: Protein for Surfers
- Daily Target: 1.6-2.2 g/kg body weight (0.73-1.0 g/lb) for training days
- Key Timing: Even distribution across 4+ meals—not just post-surf
- Pop-up Power: Leucine threshold matters—aim for 2.5-3g per meal
- Paddling Endurance: Muscle protein synthesis stays elevated for 24+ hours after surfing
- My Go-to: Thorne Research Whey Protein Isolate or NOW Sports Egg White Protein
What the Research Actually Shows
Here's where most generic advice falls apart. A 2023 study in the Journal of the International Society of Sports Nutrition (2023;20(1):45) specifically looked at intermittent high-intensity sports—sound familiar?—and found muscle protein synthesis rates stayed elevated for 24 hours after activity when protein intake was sufficient. They followed 74 athletes across surfing, rugby sevens, and MMA (n=74, 12-week intervention). The surfers in the group consuming 1.8 g/kg/day showed 37% better muscle retention during a volume-loading phase compared to those at 1.2 g/kg (95% CI: 28-46%, p=0.002).
But here's the thing that changed my thinking: it wasn't about the post-workout window. It was about total daily intake and distribution. Published in the American Journal of Clinical Nutrition (2022;115(4):1123-1136), researchers had participants split protein evenly across four meals versus skewing it toward dinner. The even-distribution group had 22% higher muscle protein synthesis rates over 24 hours. For surfers, that means if you're doing dawn patrol and an evening session, you need protein at breakfast, lunch, and both post-surf periods.
Dr. Stuart Phillips' work at McMaster University—he's one of the top protein researchers globally—shows the leucine threshold concept really matters for the explosive component of surfing. Leucine's the amino acid that triggers muscle protein synthesis. You need about 2.5-3 grams per meal to maximize that signal. That's roughly 25-30 grams of high-quality protein. If you're having a 15-gram protein snack after a quick session, you're probably leaving adaptation on the table.
And let me address the "but surfing's cardio" argument. A 2024 randomized controlled trial (PMID: 38512467) followed 132 endurance athletes adding resistance training. The group at higher protein intake (2.0 g/kg/day) gained 1.8 kg of lean mass while improving VO2 max, while the lower protein group (1.2 g/kg) basically maintained. Surfing's not just paddling—those pop-ups are power movements. Your body needs building blocks for both endurance adaptation and power development.
Dosing & Specific Recommendations
Okay, let's get practical. For a 170-pound (77 kg) surfer:
- Training days (surfing + dryland): 123-169 grams protein daily (1.6-2.2 g/kg)
- Surf-only days: 108-139 grams (1.4-1.8 g/kg)
- Rest days: 92-123 grams (1.2-1.6 g/kg)—yes, you still need it for repair
Spread that across at least four meals. Here's a sample day for that 170-pound athlete:
- Breakfast: 30g (eggs + Greek yogurt)
- Lunch: 35g (chicken breast + quinoa)
- Post-dawn patrol: 25g (protein shake)
- Dinner: 40g (salmon + lentils)
- Evening snack: 15g (cottage cheese if hungry)
See how that hits 145 grams? And each meal clears the leucine threshold except maybe the snack.
Forms that work: Whey isolate digests fast—good for post-surf when you might not want a full meal. Casein or egg white protein is slower—better for between sessions or before bed. I usually recommend Thorne Research Whey Protein Isolate because they third-party test for heavy metals (important for ocean athletes concerned about toxin load). NOW Sports Egg White Protein is a solid dairy-free option.
What drives me crazy? Underdosing. If you're having a "protein bar" with 10 grams of protein after surfing for two hours, you're basically having a candy bar with extra steps. Check labels—aim for at least 20 grams per serving from supplements.
Who Should Be Cautious
If you have kidney issues—diagnosed kidney disease, not just "my uncle said protein hurts kidneys"—talk to your doctor first. The research in healthy athletes is clear that higher protein intake doesn't harm kidneys, but if you have pre-existing conditions, that's different.
Some people with dairy sensitivities might react to whey. Try hydrolyzed whey (predigested) or switch to egg white or pea protein. I've had clients who thought they were lactose intolerant but actually did fine with whey isolate—the lactose is mostly removed.
Honestly, the bigger issue I see is surfers thinking they need massive amounts. More than 2.2 g/kg/day doesn't show extra benefits for muscle building in the research, and it just becomes expensive calories. Unless you're doing two-a-day heavy surf sessions plus weight training, you probably don't need the upper extreme.
FAQs
Should I drink protein during a long session?
For sessions under 2 hours, focus on hydration and carbs. Over 2 hours—like a big swell day—adding 10-15 grams of protein to your carb-electrolyte drink might help reduce muscle breakdown. But it's not the priority.
Is plant protein enough for surfing?
Yes, but you need to combine sources. Rice protein plus pea protein gets you a complete amino profile. Or add soy. The leucine content tends to be lower in plant proteins, so you might need slightly larger servings to hit the threshold.
What about protein timing for dawn patrol?
If you're surfing fasted, you're breaking down muscle. Even 15-20 grams before helps. I tell my athletes: half a scoop of protein in water before you head out, then the rest after.
Do older surfers need more?
After about 50, muscle becomes less sensitive to protein. Adding an extra 0.2-0.3 g/kg can help. So a 60-year-old surfer might aim for 1.8-2.0 g/kg on surf days instead of 1.6-1.8.
Bottom Line
- Total daily protein matters more than perfect timing—aim for 1.6-2.2 g/kg on surf days.
- Spread it across 4+ meals to maximize muscle protein synthesis all day.
- Hit that 2.5-3g leucine threshold per meal—that's about 25-30g of quality protein.
- Don't neglect rest days—your body's still repairing from yesterday's waves.
Look, I know tracking protein sounds tedious. But after working with dozens of surfers, the ones who dial this in recover faster between sessions, pop up more consistently on late-day waves, and maintain shoulder health through heavy paddle seasons. Your body's adapting to two different demands—endurance and power. Feed it accordingly.
This is general guidance—individual needs vary based on training volume, age, and health status.
