Does Stretching Reduce Soreness? What the Trials Actually Found

Does stretching reduce soreness? It’s one of the first questions I asked when I started training seriously, and for years I assumed the answer was obviously yes. I was stretching religiously after every long run, holding each position for 30 to 60 seconds, convinced I was doing the responsible thing. Then a training partner of mine, a physical therapist who works with collegiate runners, sat me down and said: “The evidence really doesn’t back that up.” I pushed back. She handed me a stack of papers. Reader, she was right.

This article is my attempt to translate what those papers actually say, because the gap between what the fitness world believes about stretching and what the controlled trials show is genuinely startling. If you train regularly and you’re investing real time in post-workout stretching to prevent delayed onset muscle soreness, you deserve an honest look at the science before you commit another decade to it.

What “Stretching Reduces Soreness” Actually Claims

This article is part of our muscle recovery guide.

When people say stretching reduces soreness, they’re usually talking about one of two things. First, pre-workout stretching that may support muscle preparation and may help reduce damage. Second, post-workout stretching that is supposed to flush out metabolic waste and reduce next-day stiffness.

Both ideas are intuitive. Muscles that are more pliable should sustain less micro-tear damage, the thinking goes. And gentle movement after exercise should help circulation and speed recovery. These are reasonable hypotheses. The problem is that hypotheses need to survive controlled testing, and the stretching-and-DOMS hypothesis has had a rough time in the lab.

Understanding why requires a quick look at what DOMS actually is, because most people have the mechanism slightly wrong.

What DOMS Is (And What It Isn’t)

Delayed onset muscle soreness is the stiffness and tenderness that peaks roughly 24 to 72 hours after unfamiliar or high-intensity exercise. For years, it was attributed to lactic acid accumulation. That idea has largely been abandoned. Lactic acid clears from muscle tissue within an hour of exercise completion. It is not sitting in your legs two days later causing pain.

The current consensus is that DOMS results primarily from microscopic structural damage to muscle fibers, particularly during eccentric contractions (think: the lowering phase of a squat, or the foot-strike phase of running downhill). That micro-damage triggers a local inflammatory response, involving cytokines, neutrophils, and prostaglandins, and it’s the inflammation and resulting sensitization of pain receptors that you feel as soreness.

This matters for the stretching question because stretching, at the intensities people actually use it, does not meaningfully address structural fiber damage or the downstream inflammatory signaling. It acts on passive tissue extensibility and the nervous system’s tolerance for stretch. Those are real effects. They’re just not the effects that drive DOMS.

Does Stretching Reduce Soreness? The Clinical Trials

The most cited review on this topic is Herbert and Gabriel’s work, published in the British Medical Journal, which pooled data from five randomized controlled trials examining whether stretching before or after exercise reduced next-day muscle soreness. Their conclusion was direct: stretching does not produce clinically important reductions in muscle soreness in healthy adults.

A subsequent Cochrane-style review by Herbert, de Noronha, and Kamper expanded the dataset to twelve trials involving over 2,300 participants. The pooled effect size was small to trivial: stretching reduced soreness by less than two points on a 100-point scale. The authors concluded the effect was “too small to be of clinical importance.”

Similarly, a review published in the Journal of Athletic Training found no significant reduction in DOMS from static stretching protocols performed either before or after exercise, while noting that stretching may still have value for flexibility and injury risk in specific contexts. That’s an important nuance worth holding onto.

In addition, research published in the Journal of Human Kinetics specifically examining post-exercise static stretching found no statistically significant difference in 24-hour or 48-hour soreness scores between stretching and non-stretching groups following eccentric exercise protocols. The DOMS showed up on schedule regardless.

Why Static Stretching Recovery Doesn’t Work the Way We Think

Static stretching recovery is appealing partly because it feels like you’re doing something productive. The muscle feels tight, you lengthen it, the tightness decreases, and that sensation gets associated with recovery. However, what you’re actually doing when you hold a stretch is training your nervous system to tolerate a position, not repairing fiber damage or reducing inflammatory markers.

For static stretching to reduce soreness, it would need to either prevent the initial micro-trauma (it doesn’t, because you’re stretching after training), or modulate the inflammatory cascade that follows (there’s no strong mechanistic pathway for that at low-load stretch intensities). The felt sense of relief after stretching is real but it’s largely neurological, a temporary reduction in the perception of tension, rather than a sign that tissue repair is accelerating.

Furthermore, some research suggests that aggressive stretching of already-damaged muscle tissue could theoretically prolong recovery. A paper in Medicine & Science in Sports & Exercise noted that overly forceful stretching of eccentrically loaded muscle may contribute to additional micro-damage rather than relieve it. Most people aren’t stretching aggressively enough for this to be a real concern in practice, but it’s a reason to keep post-workout stretching gentle regardless.

What Stretching After a Workout Actually Does Well

Here’s where I want to be careful not to overcorrect. Just because stretching and DOMS aren’t meaningfully linked doesn’t mean stretching is pointless. It’s pointless for one specific, common claim. It has genuine value for other things.

Regular flexibility work, particularly static stretching held 30 to 60 seconds per position, consistently improves joint range of motion over time. A review in the Journal of Human Kinetics documented reliable gains in hamstring flexibility from consistent static stretching programs, with benefits accumulating over 4 to 8 weeks of regular practice.

There’s also evidence that stretching supports the cool-down process by gradually lowering heart rate, returning the nervous system toward parasympathetic dominance, and creating a mental transition between hard effort and rest. These are real training benefits. They just don’t show up as reduced soreness scores on a pain scale 48 hours later.

In my experience working with endurance athletes, the ones who drop stretching entirely because “the data says it doesn’t reduce soreness” often end up stiffer, more restricted, and slower to progress on mobility-dependent movements. Stretching belongs in your program. It just doesn’t belong in the “this is why I’m less sore” column.

What the Evidence Actually Supports for DOMS Recovery

If stretching isn’t the answer for reducing soreness, what is? The honest answer is that DOMS is partly a signal that your training is stimulating adaptation, and chasing zero soreness isn’t always the right goal. That said, the research does support a few approaches for meaningful reduction in soreness intensity and duration.

Active recovery, meaning light aerobic movement at low intensity, has better evidence than static stretching for short-term soreness relief. The mechanism is increased blood flow to recovering tissue, which may help clear inflammatory byproducts and deliver substrates for repair. A brisk walk, an easy bike session, or a slow swim the day after heavy training consistently outperforms lying still in studies.

Nutritional support also has legitimate trial data behind it. Tart cherry supplementation has been studied specifically for DOMS, with research published in the Scandinavian Journal of Medicine & Science in Sports finding that marathon runners who consumed tart cherry juice for five days before and two days after a race reported significantly less soreness than controls. The proposed mechanism involves anthocyanin-driven modulation of the inflammatory response.

Magnesium is another ingredient with a rational mechanism for supporting recovery. It plays roles in muscle contraction, protein synthesis, and energy metabolism. Getting adequate magnesium may support the cellular conditions under which repair happens more efficiently, even if it won’t eliminate DOMS entirely.

Sleep is consistently underestimated. During deep sleep, the body releases growth hormone, which is a primary driver of tissue repair. Shortchanging sleep doesn’t just affect performance, it extends recovery timelines. This is something I now talk about with every athlete I work with before we discuss any supplement or protocol.

Here’s the protocol I now recommend to my clients: light active recovery the day after a hard session, consistent attention to sleep quality, tart cherry or magnesium support where it makes sense, and stretching for the flexibility and cool-down benefits it actually delivers. What I’ve stopped telling them is that their evening stretch routine is the reason they’re less sore two days later. It probably isn’t.

Where Klova’s Recovery Patch Fits

Athletes I work with often want something that supports recovery overnight, when the bulk of repair actually happens. Klova’s Recovery Patches are one tool that fits neatly into that gap. The active ingredients are absorbed right through the skin over an 8-hour window, which means support is delivered steadily while you sleep rather than in a single spike from a pill you take before bed. The patches are made in an FDA-registered facility in the USA, drug-free, and use medical-grade foam with a latex-free adhesive.

It’s not a replacement for sleep, nutrition, or smart training. However, for athletes who want between-session support without adding more pills to their stack, it’s worth considering alongside the evidence-based practices above. You can read more about how recovery patch formats compare in our article on what recovery patches actually do between training sessions.

The Bottom Line on Does Stretching Reduce Soreness

Does stretching reduce soreness in any meaningful, measurable way? Based on the current body of randomized controlled trial data, the honest answer is: not really. The effect sizes are too small to be clinically relevant, and the mechanism doesn’t map well to how DOMS actually develops.

That’s a frustrating conclusion after years of post-run static stretching, I’ll admit. However, the good news is that stretching absolutely earns its place in a training program for flexibility, joint health, nervous system recovery, and the mental ritual of transitioning out of hard effort. It’s just not a soreness treatment, and framing it that way means athletes sometimes lean on it instead of approaches with stronger evidence.

Keep stretching. Add active recovery, prioritize sleep, and use targeted nutritional support where it’s warranted. That’s the recovery stack that actually lines up with what the trials found.

Frequently Asked Questions About Stretching and Soreness

Does stretching reduce soreness if you do it immediately after exercise?

Based on the clinical trial data, timing doesn’t appear to change the outcome significantly. Studies examining both pre-exercise and post-exercise static stretching have found similarly small, clinically unimportant effects on delayed onset muscle soreness scores. The reason is mechanistic: immediate post-exercise stretching does not prevent the micro-damage that drives DOMS, and it doesn’t meaningfully modulate the inflammatory signaling that follows. The soreness develops from structural events at the fiber level that passive stretch doesn’t address.

Is dynamic stretching better than static stretching for recovery?

Dynamic stretching before exercise has more support for performance preparation than static stretching does, but the evidence for either format specifically reducing post-exercise soreness is limited. Dynamic movement may improve blood flow and prime the neuromuscular system for effort, which can support performance and potentially reduce injury risk. However, neither form has demonstrated the ability to meaningfully reduce DOMS in well-controlled trials. Dynamic stretching is the better pre-workout choice; static stretching has more value for long-term flexibility gains done consistently over weeks.

What actually works for reducing DOMS if stretching doesn’t?

Active recovery (light movement the day after hard training) has better evidence than static stretching for short-term soreness relief, likely because it supports blood flow to recovering tissue. Tart cherry supplementation has randomized trial support specifically for reducing soreness in endurance athletes. Adequate sleep is critical because growth hormone, released during deep sleep, drives much of the tissue repair process. Gradually progressive training volume also reduces DOMS over time as muscles adapt to repeated bouts of similar effort, a phenomenon researchers call the “repeated bout effect.”

Can stretching make DOMS worse?

For most people performing moderate stretching at comfortable intensities, the risk of worsening DOMS is low. However, some research suggests that aggressive or forceful stretching of already eccentrically stressed muscle tissue may contribute to additional micro-damage rather than relieve it. This is generally not a concern at the stretch intensities most people use in a cool-down routine. The practical advice is to keep post-workout stretching gentle, move to the point of mild tension rather than pain, and avoid forcing range of motion on acutely sore muscle groups the day after heavy training.

Does stretching reduce soreness for beginners versus trained athletes?

Interestingly, DOMS is more pronounced in individuals new to a particular movement or exercise type, regardless of their overall fitness level. Beginners may experience more severe soreness simply because their muscles are encountering unfamiliar mechanical stress. The limited evidence available does not suggest that stretching’s effect on DOMS differs meaningfully between trained and untrained populations. Both groups show similarly small responses in controlled trials. What does differ is that trained athletes tend to recover faster overall due to the repeated bout effect and generally better recovery infrastructure (sleep, nutrition, planned periodization).
