   Caffeine may aid performance while you recover, at a cost to your sleep

   A pooled analysis of 17 trials found caffeine gave a small boost to functional performance during post-exercise recovery, had no clear effect on perceived or physiological recovery, and was associated with poorer sleep after exercise.

   ⚠What it shows: Treat this as a lean, not a verdict: results pooled from 17 trials, but the sleep harm rests on just four studies, and both the performance and sleep findings wobbled when the analysis was re-run in different ways.Systematic review · Front Physiol

   Your ice bath keeps cooling you long after you climb out

   Pooled data from 157 people in post-exercise cold-water immersion trials show that colder water, longer immersions and intermittent dunking each pull core temperature down further than their alternatives. The biggest gap versus no immersion appeared 60 minutes after the intervention ended.

   ⚠What it shows: Useful dosing detail rather than proof of benefit: the data come from 157 people pooled across one research group's own trials, and the outcome is core temperature, not whether anyone recovered faster. How that extra cooling translates to performance is a question this analysis cannot answer.Meta-analysis · Int J Sports Physiol Perform

   Ice baths help you recover but can blunt your muscle gains

   An umbrella review spanning 15 meta-analyses and 161 studies finds post-exercise cold-water immersion speeds recovery of power, jump performance and soreness, but does not aid strength recovery and impairs strength and muscle growth gains when used routinely.

   ⚠What it shows: The widest sweep of this evidence yet, covering 161 studies gathered through 15 earlier pooled reviews, and the pattern is consistent. The catch is that the authors rate the underlying evidence as low quality and inconsistent, so the exact sizes of these effects remain uncertain.Systematic review · Sports Med Open

   Tart cherry and friends ease soreness, but don't bring your performance back

   A sweep of 36 human trials found plant foods such as tart cherry, pomegranate, beetroot and berry juices often reduced perceived muscle soreness in the 24 to 72 hours after exercise, but showed no consistent benefit for muscle function, subsequent performance or blood markers, and no specific product, dose or timing could be recommended.

   ⚠What it shows: Take the big picture, not any single juice: a sweep of 36 human trials in active people found soreness relief in several of them, but products, doses and designs varied so much the authors could not pool the numbers or back any one option. Benefits beyond soreness did not hold up consistently.Systematic review · Nutrients

   Fitness after COVID takes closer to a year to return, not months

   Pooled data from 106 studies covering 20,063 adults show physical function is still reduced 3 months after COVID-19 infection: walking distance averaged 84.3% of predicted at 3 to 5 months, climbing to 92.5% of predicted at 11 months or later.

   ⚠What it shows: A broad pooled picture rather than one trial: 106 studies following 20,063 adults for up to two years, though many had been hospitalised and the studies disagreed with each other considerably. Your own recovery curve could look quite different from these averages.Meta-analysis · Phys Ther

   The ice bath beats the cryo chamber for next-day soreness

   A meta-analysis of 13 randomised trials in 214 physically active people found cold water immersion relieved delayed onset muscle soreness better than body cryotherapy within 24 hours of strenuous exercise, while cryotherapy showed only a small and fragile edge in jump performance recovery at 24 hours. By 48 hours neither method held a significant advantage.

   ⚠What it shows: Fairly solid for the soreness result: it pools results from 13 trials of 214 active people, and those trials agreed with each other on soreness. They disagreed on jump performance, so cryotherapy's small edge there deserves little weight.Meta-analysis · Medicine (Baltimore)

   Pre-exercise light therapy helped athletes and the sedentary, not the in-between

   Pooled results from 34 randomised trials found that applying photobiomodulation, a light-based therapy, to muscles before exercise improved muscle endurance and speeded recovery of strength and muscle damage markers. The benefit appeared in athletes and physically inactive people but not in moderately active people.

   ⚠What it shows: Worth a raised eyebrow rather than a rush to buy a laser: results pooled from 34 trials show modest average benefits, but the strange split, helping athletes and the sedentary yet not regular exercisers, comes from comparisons between subsets of trials that are easy to over-read. The authors themselves note the field is still controversial.Meta-analysis · Lasers Med Sci

   Ice baths beat doing nothing for soreness, but only slightly

   Pooled results from nine randomised trials found cold water immersion slightly better than passive recovery for muscle soreness, both immediately after exercise and days later. The pooled data suggested a dose-response pattern, with the best results at water temperatures of 11 to 15 °C and immersion times of 11 to 15 minutes.

   ⚠What it shows: Reasonably trustworthy but modest: results pooled from nine trials where people were assigned at random, all comparing cold water immersion with simply resting. The benefit for soreness was small, and with so few studies the ideal temperature and time are best treated as a signal rather than a settled recipe.Meta-analysis · Sports Med

   Tart cherry eases the ache but does not speed the repair

   A network meta-analysis of 30 trials in 595 healthy adults found that tart cherry and pomegranate reduced muscle soreness at 48 hours after damaging exercise, but no polyphenol supplement showed clear benefits for muscle strength or blood markers of damage and inflammation.

   ⚠What it shows: Worth a measured read: the soreness relief looks plausible but the authors rate the overall evidence as low certainty, pooled from 30 trials totalling 595 healthy adults. Objective recovery measures did not improve for any supplement tested.Systematic review · Front Nutr

    Foam rolling did nothing measurable for post-workout soreness

    Pooled results from five trials in 151 healthy adults found foam rolling or stick massage after damaging exercise made no significant difference to muscle soreness at any point from immediately afterwards to 96 hours, nor to range of motion, muscle swelling, or strength recovery.

    ⚠What it shows: Take it as a strong hint rather than a settled verdict: results pooled from only five trials covering 151 healthy adults, 136 of them men, and the quality was middling at best, so the authors themselves stop short of a definite conclusion.Meta-analysis · J Bodyw Mov Ther

    Curcumin takes the edge off post-workout soreness

    Curcumin supplementation reduced blood markers of exercise-induced muscle damage and eased delayed-onset muscle soreness in pooled randomised trials, lowering creatine kinase by 48.54 IU/L on average.

    ⚠What it shows: Reasonable evidence for a modest effect: results pooled from randomised trials in adults showed less soreness and lower muscle-damage markers after curcumin. Doses, exercise types and study lengths varied widely, so how much relief any one person would notice is uncertain.Meta-analysis · Phytother Res

    Ice baths restore performance after team sport, but not the soreness

    Cold water immersion aided recovery of jump and sprint performance 24 hours after team sport and reduced perceived fatigue at 72 hours in pooled data from 23 studies; neither cold water immersion nor contrast water therapy improved perceived muscle soreness.

    ⚠What it shows: Reasonable evidence for athletes: results pooled from 23 studies with 606 team sport players. The benefits were selective, with some performance and fatigue measures improving while perceived soreness did not, so it is not a blanket recovery fix.Meta-analysis · J Strength Cond Res

    Heat eases sore muscles as well as ice does

    Across 32 randomised trials in 1098 people, both cold and heat applied within an hour of exercise reduced the pain of delayed onset muscle soreness; cold helped mainly within 24 hours, heat helped both within and beyond 24 hours, hot packs showed the largest effects, and there was no significant difference between cold and heat overall.

    ⚠What it shows: Trustworthy on direction, fuzzy on size: results pooled from 32 trials with 1098 people, but the trials varied widely in how heat and cold were applied and the authors themselves call for better studies. Head to head, neither therapy clearly beat the other.Meta-analysis · Phys Ther Sport

    Beetroot juice blunts muscle damage after hard exercise

    Pooled results from seven randomised trials suggest beetroot juice supplementation reduces the muscle damage marker creatine kinase and improves strength, jump performance and soreness threshold after damaging exercise, while inflammation markers stay unchanged.

    ⚠What it shows: Promising but not settled: results pooled from seven trials, and the trials disagreed with each other on several outcomes, so the exact size of the benefit is uncertain. Inflammation markers did not move, which muddies the simplest explanation for how it works.Study · Ann Med Surg (Lond)

    Cryotherapy chambers: the evidence still isn't there

    A Cochrane review of four small laboratory trials (64 physically active, predominantly young male adults) found insufficient, very low quality evidence that whole-body cryotherapy reduces self-reported muscle soreness or improves subjective recovery compared with rest. Confidence intervals at 24, 48 and 72 hours included no difference, and no trial actively monitored adverse events.

    ⚠What it shows: Cochrane review of only four laboratory trials covering 64 physically active young adults, all but four of them male, mean age 23; every trial had design features carrying a high risk of bias and all outcomes were graded very low quality, with no data at all in women or elite athletes.Meta-analysis · Cochrane Database Syst Rev

    Shockwave added little to exercise for jumper's knee

    Athletes with jumper's knee who added radial pressure wave (shockwave-style) therapy to daily stretching and strengthening gained no statistically significant extra benefit once symptom duration was accounted for. Both groups achieved clinically meaningful improvement over 28 weeks, though the treated group reached that threshold earlier.

    ⚠What it shows: One open-label RCT of 33 young athletes; the treated group's advantage at 28 weeks lost significance after adjusting for symptom duration, and a modest true effect cannot be ruled out.Study · Transl Sports Med

    Kinesiotape barely moves the needle for shoulder pain

    Across 39 randomised trials totalling 2,481 people with rotator cuff-related shoulder pain, kinesiotape offered at best small, short-term improvements in shoulder function and pain during activity, with uncertain effects on range of motion. The reviewers conclude tape may serve as an adjunct but should not replace education-focused, exercise-based rehabilitation.

    ⚠What it shows: Systematic review and meta-analysis of 39 RCTs (n=2,481), but the overall certainty of evidence was rated low to very low, so even the small pooled effects are uncertain.Review · Shoulder Elbow

    Laser acupuncture beat sham for chronic low back pain

    In a double-blind, sham-controlled trial of 60 adults with chronic non-specific low back pain, both high- and low-intensity laser acupuncture added to exercise outperformed sham laser plus exercise on pain, trunk strength, mobility, fatigue and disability. The high-intensity version delivered greater gains in trunk extensor strength and pain relief.

    ⚠What it shows: One RCT, n=60 split across three groups; a four-week intervention with only a one-month follow-up, and the authors say optimal parameters and long-term effects need further research.Clinical trial · Front Med (Lausanne)

    Frozen shoulder: hydrodilatation adds little over steroids

    A systematic review of 103 studies (9951 patients, 44 randomised trials) found that distending the shoulder capsule with fluid gave slightly more external rotation than a corticosteroid injection alone at 12 weeks, with no better pain or disability scores, and only marginal pain gains when added to physiotherapy. Technique varied enormously between clinics.

    ⚠What it shows: Systematic review with meta-analysis of 44 RCTs, but the significant findings were rated low or very low certainty with high heterogeneity (I2 up to 81.6%), and pooled techniques differed so widely that an optimal protocol could not be identified.Study · Br J Sports Med

    Ice packs failed to speed recovery, whenever applied

    Applying cold packs to worked muscles made no meaningful difference to soreness or strength recovery after damaging exercise: whether cooling started immediately or 24 hours later. Both cooled groups tracked the same recovery curve as controls who received no cold at all.

    ⚠What it shows: One RCT, n=48 healthy young adults (39 women, 9 men, mean age 22), local gel packs on one muscle only; findings may not extend to whole-body cold immersion, colder protocols or trained athletes.Study · Int J Environ Res Public Health

    Cold plunges eased soreness, not strength recovery

    Pooling 22 randomised trials, a single cold-water immersion after exercise did nothing for maximal isometric strength recovery and transiently blunted jump performance immediately afterwards, while its apparent benefit for muscle-damage markers vanished once publication bias was accounted for. The one reasonably consistent effect was lower reported soreness.
