How to read this guide

It completes the guide on cold water, cryotherapy and massage guns, with the same rules: three different questions (how it feels, performance and adaptations, injury), no recommended temperature, duration or frequency, and the certainty of the evidence stated. The reviews cited use different methods and do not always agree: we say so where it happens.

Compression

  • Perceived recovery: A 2026 meta-analysis of 9 studies (158 participants, endurance athletes) finds soreness at about 24 hours leaning towards compression, but the estimate is very uncertain (the interval includes no effect). Blinding was limited, so expectations may play a part. Very low certainty.1 A larger 2018 meta-analysis of 99 studies (all techniques) indicated that perceived fatigue can be managed with compressive techniques, including garments, massage and immersion.2
  • Performance: The 2026 meta-analysis could not pool the results on later performance. For garments worn while running (51 studies, 899 participants), no improvement in race time or time to exhaustion, low to very low certainty. This is not about use after running.1,3
  • Safety: For medical compression (stockings and bandages) an international consensus describes skin irritation, discomfort and pain as the most frequent effects, and severe complications as very rare, in predisposed people or with incorrect use. It recommends screening for risk conditions and checking the fit. It is a document on medical devices: it says nothing about sports garments, which have different pressures. With circulation, heart or skin problems, ask a doctor.4

Manual massage

  • Perceived recovery: A 2020 systematic review with meta-analysis (29 studies, 1012 participants) finds small but statistically significant improvements in soreness (DOMS) and flexibility.5
  • Performance: The same review finds no evidence that massage improves strength, jump, sprint, endurance or fatigue.5 The 2018 meta-analysis above ranked it as the most effective technique for soreness and perceived fatigue: the reviews do not agree.2
  • Safety and limits: The sources read do not analyse the safety of manual massage. Pain that persists or has an unclear cause needs assessment, not massage.

Stretching after exercise

  • Perceived recovery: The Cochrane review (12 studies, low to moderate quality) concludes that stretching before, after, or before and after exercise does not reduce delayed-onset muscle soreness in a clinically important way. For post-exercise stretching the mean difference at one day is about 1 point on a 100-point scale, with an interval that includes no effect.6
  • Limits: The review is about soreness after exercise. It does not say stretching is useless for flexibility or other purposes.6

Active cool-down

  • What it shows: A 2018 narrative review concludes that an active cool-down (light to moderate exercise right after activity) is largely ineffective for same-day and later performance, although some studies show next-day benefits. It does not seem to prevent injury, and for most markers studied it shows no benefit. It speeds the fall of blood lactate, not necessarily muscle lactate, and may interfere with glycogen resynthesis. The authors say it is not known whether it reduces fainting or cardiovascular complications after effort.7
  • Limits: It is a narrative review, not a meta-analysis.

Heat and contrast water

  • Heat (sauna, hot immersion): A 2025 systematic review of 14 studies (194 participants) finds uncertain results for acute recovery: 4 studies with no effect, 4 favourable, 1 adverse on performance recovery. Long-term studies suggest a possible improvement in running in hot conditions, no effect on cycling or VO₂max. Low to moderate quality. The authors draw no definitive conclusions.8
  • Contrast (hot-cold): A 2013 review (18 studies, all at high risk of bias) finds less soreness and less strength loss than passive rest, but little evidence of superiority over other methods. Old data of weak quality.9
  • Safety: The heat sources read do not analyse safety. People with cardiovascular or blood pressure problems, or who are pregnant, should ask a doctor before using a sauna or hot baths. For the cold water in contrast therapy, the risks in the cold water section apply.

Electrical stimulation

  • What it shows: A 2014 systematic review of 13 studies (healthy people, low-intensity stimulation after exercise) finds few favourable results: 3 studies for perceived pain, 3 for blood lactate, 1 for creatine kinase and only 1 for a performance measure. In the lactate meta-analysis, no evidence in favour compared with active recovery and mixed results compared with rest. The authors conclude there may be subjective benefits, but the evidence is not convincing to support it for improving later performance.10
  • Limits: The review is from 2014 (search to 2012): newer studies were not read. No device settings are given. Safety was not analysed in the sources read. For strength, endurance, TENS and precautions see the dedicated guide.

Hyperbaric oxygen therapy

  • What it shows: The reviews disagree and cover different outcomes. A Cochrane review (9 small trials, 219 participants, search to 2010) finds no evidence of benefit for muscle soreness after unaccustomed exercise, and in 7 trials on soreness after eccentric exercise it finds more pain at 48 and 72 hours in the treated group when therapy started immediately.13 A 2021 meta-analysis (10 studies, 166 participants, 6 in the quantitative synthesis) finds no significant effect of a session before or after exercise on performance and recovery; for therapy during exercise some single studies are favourable, with no meta-analysis.12 A 2025 meta-analysis (10 studies, 299 participants) finds a statistically significant improvement in muscle injury outcomes, but no benefit for muscle soreness.11
  • Limits and safety: The studies are small and use different conditions. It is a therapy in a pressurised chamber, not an ordinary recovery habit: the sources read do not analyse its risks and contraindications, so any assessment belongs to a doctor. The result on muscle injury outcomes does not mean performance improves.

What is left

For these methods the reviews read show no clear, consistent benefit on later performance: for heat some studies are favourable and others not, for compression the data are uncertain, for massage and stretching no effect on performance emerges, for electrical stimulation the evidence is not convincing and for hyperbaric oxygen the reviews disagree. Some may feel better: if they suit the person using them and carry no risk, the cost is time and money. Sleep, food and load management remain the base: see sleep and recovery, marathon carbohydrates and race taper. For injury pain, see the injury section.

How we reviewed it

Document review of the sources: meta-analyses, Cochrane, one narrative review and a consensus on medical compression. Abstracts and main sections read; not every full text or primary study. No WOLF LAB tests.

Limits. Reviews with different methods and conclusions, sometimes conflicting. No protocol given. Safety not analysed in the sources on massage, heat, electrical stimulation and hyperbaric oxygen; the compression consensus covers medical devices, not sports garments. Electrical stimulation rests on a 2014 review. Does not cover supplements and nutrition (other pages) or drugs. Not medical advice.
