Tart Cherry for Tennis Players: What the Research Actually Says About Recovery
If you follow athletes or wellness accounts, you've probably seen tart cherry everywhere: juices, powders, capsules, "recovery shots." The pitch is usually that it helps your muscles bounce back after hard training.
Is that true? Partly, and with a lot of fine print. Here's a plain-language look at what the research actually found, and what it means for someone who plays tennis for fun and fitness.
What Is Tart Cherry?
Tart cherries, also called sour cherries, are a different fruit from the sweet cherries you snack on. The variety most often studied in sports research is Montmorency. They're tested as juice, juice concentrate, powder and supplements.
What the Research Found
A widely referenced 2021 review pooled 14 studies on tart cherry and recovery from strenuous exercise (Hill and colleagues). Across those studies, the participants who took tart cherry showed:
- Moderate improvements in strength recovery after hard exercise
- Moderate improvements in muscle power recovery, including jump height
- A small reduction in muscle soreness
- Small changes in some blood markers of inflammation
- No significant effect on creatine kinase, a marker of muscle damage
- In other words, the effects were real in the data but modest, and they were strongest for strength and power, not soreness.
The Fine Print
Before you head to the juice aisle, here's what the studies don't tell us.
The studies were small. Sample sizes ranged from 10 to 54 people.
Most participants were men. The review included 223 men and 71 women. If you're a woman who plays tennis, you're underrepresented in this evidence.
Results were inconsistent. Senior author Glyn Howatson noted differences in study design, diet control, participants, and type of exercise. Benefits appeared larger after more metabolically demanding exercise, which may not match a relaxed doubles hit.
The protocols were specific. Studies typically gave one to two servings a day of juice, concentrate, powder or supplements for 7 to 16 days around the exercise. Taking a small amount occasionally isn't the same as what the studies tested, and the amount of tart cherry in different products varies a lot.
Mechanisms aren't settled. Researchers have suggested effects on oxidative stress and inflammation, but they call for more research to understand how it might work.
What This Means for Recreational Tennis Players
Tart cherry is an interesting option, not a shortcut. If you play a few times a week, the basics will likely do more for you than any single ingredient:
- Sleep. It's when your body does much of its recovery.
- Food. Enough protein, carbohydrates, and overall calories to support how much you play.
- Hydration. Replacing fluids and electrolytes when you sweat heavily or play long matches. For long, sweaty sessions, a zero-sugar electrolyte mix like AceFit Hydrate can help replace the sodium you lose in sweat. Our guide to whether every tennis player needs an electrolyte drink can help you decide.
- Rest days and gradual increases. Leaving room between hard sessions matters more than anything you can drink.
If you're curious about tart cherry, treat it as an optional extra on top of those foundations. Our post on why you're sore after tennis and what helps covers the basics.
Things to Keep in Mind Before You Try It
- Check the label. Products vary in how much tart cherry they contain and in what form. Juice and concentrate also contain natural sugars.
- Talk to a professional if you have a health condition. If you take medication, are pregnant or nursing, or have a condition such as diabetes, check with your doctor or a registered dietitian before adding a new supplement.
- Don't use it to push through pain. Soreness that's severe, sudden or doesn't settle is something to get checked, not something to treat with a drink.
Frequently Asked Questions
Does tart cherry help with muscle soreness?
Some research suggests a small reduction in soreness, along with stronger effects on how quickly strength and power return after hard exercise. The evidence is modest, and results vary between studies.
How much tart cherry did the studies use?
Typically one to two servings a day for about 7 to 16 days around the exercise, using juice, concentrate, powder, or supplements. There's no official recommendation for tennis players. A registered dietitian can advise you.
Is tart cherry better than rest and sleep?
No. The research looks at tart cherry as an addition to normal recovery habits, not a replacement for them.
Is tart cherry safe for everyone?
Not necessarily. Ask your doctor if you take medication, are pregnant or nursing, or have a health condition.
The Bottom Line
Tart cherry has an interesting, but modest, evidence base for how quickly strength and power return after hard exercise. It isn't magic, and most of the research wasn't done on women who play recreational tennis. Build your recovery on sleep, food, hydration, and rest first. If tart cherry appeals to you, it's something to add on top, with realistic expectations.
