Most players who’ve heard the “eat protein after exercise” advice nod along and then don’t do much about it. Protein shakes feel like a gym thing — not a recreational pickleball thing.
But underneath that advice is a question almost nobody asks: does the source of protein actually matter? And for players in their 60s, does any of it make a measurable difference?
Why It Matters More After 60
Every time you play — lunging for a wide ball, grinding through a long rally, absorbing the impact of a hard overhead — you create small amounts of muscle damage that your body then repairs. That repair process is how muscle is maintained.
The problem after 60 is that this repair system becomes less sensitive. Older muscles require more protein to trigger the same rebuilding response that younger muscles get from less. So the recovery window immediately after playing — when muscles are most receptive to amino acids — becomes more meaningful with age, not less.
That’s the backdrop for a study published this spring, which set out to answer a deceptively simple question: does it matter what kind of protein you eat in that window?
The 8-Week Experiment
Researchers recruited 17 untrained adults between 60 and 70. All followed the same strength training program — leg press, squats, bench, rows — three supervised sessions per week for 8 weeks. Immediately after each session, one group drank 25 grams of whey protein isolate. The other ate 24.5 grams of protein from high-protein yogurt.
The workout plan stayed the same for both groups. The timing stayed the same too. The main change was the protein source.
Before and after the 8 weeks, researchers measured skeletal muscle mass, bench and leg press strength, quad torque, walking speed, and — in a detail that would turn out to matter — gut microbiome composition.
Same Muscles, Different Gut
On muscle, the two groups were nearly indistinguishable. Both gained roughly half a kilogram of skeletal muscle mass. Bench press, leg press, quad strength, and gait speed improved at the same rate in both groups. No statistically significant difference between them.
Whey protein works. And so does yogurt. For muscle gains in untrained adults over 60, the source mattered less than getting adequate protein in the post-training window at all.
But the gut microbiome told a different story.
The yogurt group showed a meaningful increase in microbiome diversity — a broader range of bacterial species. Specifically, it increased a bacterium called Coprococcus, which produces butyrate. Butyrate feeds the cells lining your gut and is linked to lower systemic inflammation. The whey group shifted differently: more Firmicutes, less diversity, no increase in butyrate producers.
Same muscles. Different internal environment.
What This Means for Your Court Bag
Getting protein in the 30 minutes after you play matters. And the form is more flexible than the supplement industry suggests.
- A high-protein Greek or Icelandic (skyr) yogurt — at least 15 grams per serving — covers the post-game window and appears to do additional work in the gut. Flavored varieties typically trade protein for sugar; check the label.
- Eating immediately after isn’t always possible. A small serving on the drive home still counts. The window is roughly 30 minutes, not a precise countdown.
- This matters most when total daily protein is on the lower end. If you’re already eating protein consistently through the day, the post-game source is less critical.
If Recovery Is Still Slower Than It Used to Be
Yogurt helps. So does any good protein source in that window. But the research is clear on one thing: after 60, the body becomes less efficient at synthesizing muscle protein from food alone. You need more to trigger the same repair response you’d have gotten at 40 — and real-world protein timing is hard to nail every session, every week.
That’s the gap Advanced Amino Formula from Advanced Bionutritionals was built for. It delivers all eight essential amino acids your muscles need to rebuild — in a form your body can put to work right away. Not a protein powder. A targeted recovery tool for players putting consistent demand on their legs and wanting to feel ready for the next session.
