Compression garments — tight sleeves, tights and socks worn during or after exercise — show small but consistent benefits for recovery in pooled trial data. A 2014 meta-analysis in Sports Medicine by Hill and colleagues, covering dozens of trials, found wearing compression after exercise reduced perceived muscle soreness, and a later review found similar effects on strength recovery and blood markers of muscle damage. The effects are modest in size and best documented when the garments are worn for hours or overnight after damaging exercise.

What did the main meta-analyses find?
The most cited analysis, by Jessica Hill and colleagues at the University of Brighton and published in Sports Medicine in 2014, pooled trials of compression garments worn during, after, or both during and after exercise. Compared with passive recovery or loose clothing, compression produced small positive effects on perceived muscle soreness in the days after exercise, along with smaller declines in muscle strength and power and modestly lower creatine kinase — a blood marker of muscle damage.
A 2016 systematic review by Marqués-Jiménez and colleagues in Sports Medicine, focused on subjective measures, reached a compatible conclusion: perceived soreness and fatigue were lower with compression across the pooled studies. The reviewers' consistent caveat was heterogeneity — garment pressures, types, durations, and exercise protocols varied widely between trials.
How are compression garments supposed to work?
The proposed mechanisms are mechanical. Graduated compression — tighter at the extremity, looser toward the torso — is thought to assist venous return, reduce swelling and fluid pooling in the limbs after damaging exercise, and provide mechanical support to vibrating muscle tissue during exercise. Better fluid clearance, in turn, is proposed to reduce the sensation of soreness and speed the return of strength.
Direct mechanistic confirmation in humans is partial. Trials show changes in limb circumference and some blood markers with compression, but studies have not cleanly connected those changes to the performance effects. As with many recovery tools, the outcome evidence is stronger than the mechanism evidence.
Wearing during exercise or only after?
Both patterns appear in the literature. Trials in runners, including field research at endurance events, generally tested garments worn during exercise and sometimes for hours afterward. Recovery-focused studies — including trials in which athletes wore tights or sleeves overnight after a hard session — tend to show the clearest soreness and strength-recovery effects, though overnight wear was studied in only a few trials.
For performance during exercise, the evidence is weaker. Pooled analyses find little to no improvement in actual performance output while wearing compression — the garments' documented value is in how athletes feel and perform in the days after, not in the session itself.
How big are the effects?
Small to moderate, and honest reporting requires that framing. In the Hill meta-analysis, compression reduced soreness by a fraction of the scale used, and preserved a few percent of strength compared with control conditions in the days after damaging exercise. For an athlete in a tournament with repeated efforts across consecutive days, a few percent of preserved power may matter; for a gym-goer with full rest days between sessions, the practical difference may be barely perceptible.

| Perceived soreness | Small consistent reduction | Hill et al., Sports Medicine, 2014; Marqués-Jiménez et al., 2016 |
| Strength/power recovery | Smaller post-exercise declines | Hill et al., Sports Medicine, 2014 |
| Creatine kinase (damage marker) | Modestly lower with compression | Hill et al., Sports Medicine, 2014 |
| Performance while wearing | No reliable improvement | Pooled analyses through 2018 |
Does garment quality or pressure matter?
Probably, but the research cannot yet rank products. Trials used a wide range of pressures — and few measured the pressure actually delivered at the limb, which is the variable mechanistic reasoning points to. Sports-science reviewers have noted that garment pressure of roughly 15 to 25 millimeters of mercury at the calf has been associated with measurable venous effects in medical compression research, but sports garments vary widely and are not standardized to those grades. Brand-to-brand comparisons of outcome effects do not exist in the published record.
Who should be cautious?
Compression wear at sports pressures is low-risk for healthy people, with most reports limited to discomfort, heat, or skin irritation. Medical-grade compression is a different category: people with peripheral arterial disease, deep-vein thrombosis history, heart failure, or neuropathy are advised to consult a clinician before using compressive garments, since restricting already-compromised circulation can be harmful. Athletes flying after competition sometimes use travel compression socks; the same medical cautions apply.
What populations were studied?
The trial base skews toward young, trained men, a pattern common across recovery research. The pooled studies cover male and female recreational and competitive athletes across running, team sports, and strength exercise, but individual trials were small — typically ten to twenty participants per arm — and few reported sex-specific results. Evidence in older athletes is sparse.
Medical compression is a different, larger literature. Graduated compression stockings have decades of clinical research in hospital patients and long-haul travelers for circulatory outcomes, which is where the pressure standards come from. Sports garments borrowed the concept but not the standardization, so findings from medical compression cannot be transferred to sports sleeves and tights directly — a distinction reviews in Sports Medicine have repeatedly drawn.
How does compression compare with other recovery tools?
In the Dupuy and colleagues 2018 meta-analysis in Frontiers in Physiology, which compared recovery technique families, compression garments, cold water immersion and massage came out as the techniques with the most consistent positive evidence for subjective recovery — compression being the gentlest and logistically easiest of the three. Unlike cold water immersion, compression has not been shown to blunt training adaptation, a documented concern with regular post-lifting ice baths in a 2015 Journal of Physiology trial by Roberts and colleagues.
What about pneumatic compression devices?
A pricier cousin deserves separation from garments: pneumatic recovery systems — inflatable boots that mechanically squeeze the legs in cycles, at club-level prices. The published work on these devices is young and mostly small: a handful of trials and reviews through the early 2020s report improved subjective recovery and some restoration of range of motion after hard exercise, but the evidence pool is far thinner than for garments, with no long-term outcome data. Manufacturer claims of dramatically accelerated recovery go beyond what the few trials show. On current evidence, the boots are a plausible comfort tool at a premium price, not a documented multiplier over the simpler methods.
One last framing: compression is a low-cost, low-risk tool whose benefits are real but measured in single-digit percentages. Athletes expecting dramatic recovery will be disappointed; athletes wanting an edge off the soreness curve have pooled data on their side.
Practical reading of the evidence
Compression garments sit in the unusual position of being cheap to use, low-burden, low-risk, and supported by pooled data for modest recovery benefits — soreness reduction chiefly, with some preserved strength after hard sessions. The effect sizes justify realistic expectations: a tool that takes an edge off the days after damaging exercise, not a transformation. Athletes with back-to-back events have the clearest use case in the published trials.
