Stretching after exercise to reduce muscle soreness is one of the most widely practised and most firmly believed habits in fitness. Most gym-goers, sport coaches, and personal trainers recommend it. The evidence, however, tells a more complicated story — and understanding what that evidence actually shows helps make better decisions about recovery.
What Causes Sore Muscles (DOMS)
Delayed onset muscle soreness (DOMS) is the muscular discomfort that typically develops 24 to 48 hours after unfamiliar or high-intensity exercise, particularly exercise with a significant eccentric component (muscle lengthening under load). The soreness is most pronounced between 24 and 72 hours after the exercise and typically resolves by 72 to 96 hours.
What causes DOMS:
DOMS is caused by micro-damage to the muscle fibres and the surrounding connective tissue from the eccentric loading of exercise. This micro-damage triggers an inflammatory response that produces the classic signs of soreness: pain, tenderness to touch, slight swelling, and temporary reduction in muscle force production.
What DOMS is not:
DOMS is not caused by lactic acid accumulation, as was commonly believed. Lactic acid clears from the muscles within an hour of exercise. DOMS developing 24 to 48 hours later cannot be caused by a substance that has already been metabolised. This distinction matters because many popular DOMS remedies (including some stretching claims) are based on the now-disproven lactic acid theory.
What the Evidence Shows on Stretching and DOMS
The Most Common Claim: Stretching Prevents or Reduces DOMS
What the evidence shows:
Multiple systematic reviews and meta-analyses have examined whether stretching before or after exercise prevents or reduces DOMS. The consistent finding across these reviews is that stretching does not meaningfully prevent DOMS or reduce its severity.
The most comprehensive analysis of this question — a 2011 Cochrane systematic review by Herbert and colleagues that examined 12 randomised controlled trials — found that stretching before or after exercise produced only trivially small reductions in DOMS (approximately 1 point on a 100-point scale). The authors concluded that stretching does not produce clinically important reductions in muscle soreness in the days following exercise.
Subsequent research has produced similar findings. A 2017 systematic review confirmed that post-exercise stretching does not meaningfully reduce DOMS or accelerate recovery of muscle function.
Why stretching is unlikely to address DOMS:
The mechanism makes sense when DOMS’s cause is understood. DOMS results from structural micro-damage to muscle fibres — small tears in the Z-line of the sarcomere (the basic contractile unit of the muscle). Stretching a muscle does not repair this structural damage, remove the inflammatory mediators that trigger the soreness sensation, or accelerate the cellular repair processes that resolve it.
Stretching does temporarily increase a stretched muscle’s pain tolerance (it can transiently raise the pressure pain threshold), which may create the impression that the soreness is reduced during and immediately after stretching. However, this effect is temporary and does not reflect actual resolution of the DOMS-producing tissue damage.
The Nuanced Picture: Stretching and Sore Muscles
Despite the lack of evidence for a significant DOMS-reducing effect, the complete answer is more nuanced than “stretching does nothing”:
Stretching may provide temporary symptom relief:
The transient pain-modulating effect of stretching (through gate control mechanisms in the nervous system) can make sore muscles feel temporarily better during and immediately after stretching. This is a legitimate, if short-lived, benefit for people who find the soreness uncomfortable.
Stretching maintains range of motion during DOMS:
DOMS is accompanied by some reduction in available range of motion, caused by protective guarding and the increased muscle stiffness of the inflammatory response. Gentle stretching within a comfortable range during DOMS can help maintain movement and reduce the stiffness that accumulates during the recovery period. This is different from accelerating DOMS resolution.
Stretching does not worsen DOMS:
Research has not found that moderate static stretching worsens DOMS or delays recovery. The concern that stretching damaged muscle fibres causes additional harm is not supported by evidence, provided the stretching is within a comfortable range.
The practical summary:
- Stretching does not meaningfully reduce DOMS or accelerate recovery
- Stretching may temporarily relieve DOMS symptoms during the stretch
- Stretching maintains range of motion during the DOMS period
- Stretching does not worsen DOMS
What Actually Helps Sore Muscles
Since stretching’s contribution to DOMS resolution is minimal, understanding what does help is practically important.
Active Recovery (Most Supported)
Low-intensity movement of the sore muscles — light walking, gentle cycling, swimming at easy effort — is the most consistently evidence-supported intervention for DOMS management. Active recovery:
- Increases blood flow to the sore muscles, facilitating delivery of nutrients and removal of inflammatory metabolites
- Maintains the pumping action of the venous and lymphatic systems that assists in clearing the inflammation
- Provides temporary pain relief through movement-induced analgesia (similar to the gate control mechanism of stretching but sustained)
Research comparing active recovery to passive rest consistently finds that active recovery reduces perceived DOMS and maintains better muscle function during the recovery period.
Practical application: A 20 to 30 minute walk, a light swim, or 15 minutes of easy cycling on the day after a hard session provides active recovery benefits without adding training stress.
Cold Water Immersion (Strong Evidence)
Cold water immersion (CWI), particularly immersion in water at 11 to 15 degrees Celsius for 10 to 15 minutes, is one of the most consistently evidence-supported interventions for reducing DOMS and accelerating force recovery.
Research on cold water immersion for DOMS has found:
- Significant reductions in perceived muscle soreness at 24, 48, and 72 hours post-exercise compared to passive rest
- Faster recovery of muscle force production
- Reduced markers of inflammatory damage in blood samples
The mechanism involves vasoconstriction (reducing the inflammatory swelling response), reduced nerve conduction velocity (reducing the pain signal), and hydrostatic pressure (assisting lymphatic drainage).
Practical application: A cold bath at 11 to 15 degrees for 10 to 15 minutes within 1 hour of exercise, or on the morning of the day after exercise.
Note: Cold water immersion reduces the inflammatory signal that also drives the muscle adaptation from training. For athletes in high-volume training phases where DOMS management is the priority, CWI is appropriate. For athletes in dedicated training phases where maximising adaptation is the priority, CWI immediately after sessions may slightly blunt adaptation. This trade-off does not apply to recreational exercisers.
Massage (Moderate Evidence)
Soft tissue massage applied to sore muscles 24 to 48 hours after exercise has been found to reduce perceived DOMS and inflammatory markers in several studies. The effects are meaningful but more modest than cold water immersion.
Foam rolling (self-myofascial release) has been studied as a self-applied alternative to professional massage. Research on foam rolling for DOMS has found:
- Reductions in perceived soreness at 24, 48, and 72 hours post-exercise
- Improved pressure pain threshold (reduced soreness to touch)
- Better maintained range of motion during the DOMS period
Practical application: 10 to 15 minutes of foam rolling the sore muscle groups on the day of and the day after a hard session. As covered in the post run stretch article on this site, foam rolling is a useful recovery tool alongside (not instead of) other recovery strategies.
Sleep (Consistently Evidence-Supported)
Sleep is the primary recovery modality for all types of exercise stress, including DOMS. Growth hormone secretion (the primary driver of muscle repair) occurs predominantly during deep sleep. Inadequate sleep is associated with higher perceived DOMS, slower functional recovery, and greater injury risk.
Practical application: Prioritise 7 to 9 hours of sleep in the 48 hours following a training session that produces significant DOMS.
Nutrition (Important Supporting Role)
Protein: Adequate protein intake supports the muscle repair process that resolves DOMS-producing micro-damage. Research on protein intake and DOMS recovery has found that higher protein intakes (1.6 to 2.2 grams per kilogram of body weight per day) are associated with faster muscle function recovery compared to lower protein intakes.
Anti-inflammatory foods: Foods rich in polyphenols (tart cherry juice, blueberries, ginger, turmeric) have been found to reduce markers of exercise-induced inflammation and perceived DOMS in several studies. Tart cherry juice has the most consistent research support, with multiple studies finding reduced DOMS and faster strength recovery following supplementation.
Carbohydrates: Adequate carbohydrate intake supports glycogen resynthesis and provides the energy needed for cellular repair processes.
What Does Not Help Significantly
Non-steroidal anti-inflammatory drugs (NSAIDs): Ibuprofen and similar drugs reduce the inflammatory signal of DOMS and can reduce perceived soreness. However, the inflammation of DOMS is part of the repair and adaptation process. Regular NSAID use for DOMS management may blunt the muscle adaptation from training. They are most appropriate for managing severe, function-limiting DOMS rather than as a routine recovery tool.
Compression garments: The evidence for compression garments reducing DOMS is mixed, with some studies showing benefit and others showing no effect.
When to Stretch Sore Muscles
Given that stretching does not meaningfully accelerate DOMS resolution, the question of when to stretch sore muscles is primarily about comfort and range of motion maintenance rather than recovery.
Appropriate stretching during DOMS:
- Gentle, comfortable static stretching within the pain-free range
- Hold for 20 to 30 seconds (not 60 to 90 seconds, which may provoke unnecessary discomfort in the inflamed tissue)
- Does not need to be held to discomfort — the range of motion maintenance benefit occurs at comfortable stretch intensities
- Yoga and mobility work at reduced intensity are appropriate and provide the movement stimulus of active recovery alongside the flexibility benefit
What to avoid during significant DOMS:
- Very aggressive stretching that causes significant pain in the sore muscle
- New or unfamiliar stretches that load the already-compromised muscle in ways it has not adapted to
- Treating stretching as a recovery intervention that can replace sleep, nutrition, and active recovery
Practical Recovery Protocol for Sore Muscles
Based on the evidence reviewed above:
Day of soreness onset (24 to 48 hours post-exercise):
- 20 to 30 minutes active recovery (light walk, easy cycling)
- Foam rolling the sore muscles: 10 to 15 minutes
- Adequate protein intake (25 to 40 grams at each meal)
- 7 to 9 hours sleep
- Optional: tart cherry juice or anti-inflammatory foods
- Gentle stretching within comfortable range if desired (for comfort and range of motion)
Days 2 to 3 (peak soreness):
- Continue active recovery
- Cold water immersion if available and tolerated
- Continue sleep and nutrition priorities
- Light training session (the active recovery benefit of training at reduced intensity is well-supported)
Day 4 onwards:
- Most DOMS resolves by day 3 to 4
- Return to normal training as tolerated
Frequently Asked Questions
Should I stretch if my muscles are really sore?
Gentle stretching within a comfortable range is fine and may provide temporary relief. Aggressive stretching that causes significant pain in the sore muscle is not recommended — it adds additional stretch to already-damaged tissue without providing meaningful recovery benefit. The guideline is: stretch to where it feels like a comfortable pull, not to where the soreness is provoked.
Why does my coach or trainer always recommend stretching for sore muscles if the evidence doesn’t support it?
The recommendation to stretch sore muscles is widespread and has been practised for decades. It is based on reasonable-sounding logic (stretching loosens tight muscles, so sore tight muscles should be stretched) that preceded the specific research on DOMS mechanisms. The evidence on stretching and DOMS has accumulated primarily over the last 20 to 30 years and has not yet fully filtered into everyday coaching and training advice. The recommendation is not harmful — it just does not provide the recovery benefit most people assume it does.
Does stretching before exercise prevent muscle soreness?
No. Multiple systematic reviews have found that pre-exercise stretching does not prevent DOMS. As covered in the dynamic warm up exercises for running article on this site, an appropriate pre-exercise warm-up (dynamic movement, progressive intensity build) prepares the muscles for exercise but does not prevent the muscle damage that causes DOMS.
Will I always get sore after exercise?
DOMS is most pronounced when an exercise is new or when the volume or intensity significantly exceeds what the muscles are accustomed to. As the muscles adapt to a particular exercise stimulus (the repeated bout effect), subsequent similar sessions produce significantly less DOMS. This is why the first week of a new training programme or the first session after a long break produces much greater DOMS than the same session three weeks later.
