Recovery: Compression Garments
Meta-analysis of 23 studies: compression garments reduce DOMS by d=0.42 and improve perceived recovery by d=0.52; 15-30 mmHg is the effective pressure range for post-exercise use.
| Measure | Value | Unit | Notes |
|---|---|---|---|
| DOMS reduction effect size | 0.42 | Cohen's d | Pooled effect from Hill et al. 2014 meta-analysis of 23 studies; small-to-moderate |
| Perceived recovery effect size | 0.52 | Cohen's d | Subjective recovery ratings consistently improved; larger than the objective biomarker effects |
| Effective pressure range | 15-30 | mmHg | Grades below 15 mmHg show minimal venous return benefit; above 40 mmHg may impair circulation |
| Optimal duration post-exercise | 12-24 | hours | Most benefit observed from extended wear (overnight) versus short post-exercise sessions of 1-2 hours |
| CK reduction | ~15 | % | Creatine kinase elevation is modestly lower with compression use; indicates reduced membrane disruption markers |
| Performance effect during exercise | Neutral to small positive | — | Compression during exercise shows small vibration-damping effects; proprioception may improve; no consistent power output benefit |
Compression garments are among the most studied wearable recovery tools. Unlike some modalities, the mechanism — enhanced venous return — is well-established in vascular physiology. The question is whether the pressure magnitudes achievable in athletic garments are sufficient to produce meaningful recovery effects.
Mechanism: Venous Return and Edema Reduction
Graduated compression (highest distally, decreasing proximally) supports the venous valves in returning blood against gravity. Post-exercise, when capillary permeability is elevated and metabolic byproducts accumulate in exercised tissue, enhanced venous return accelerates clearance. The external pressure also provides mechanical support that may limit post-exercise swelling (Beliard et al., 2015 — PMID 25782762).
Application Timing vs. Outcomes
| Application Timing | Pressure (mmHg) | Outcome Measured | Effect Size (d) | Duration | Notes |
|---|---|---|---|---|---|
| During exercise | 15-25 | Muscle damage prevention | 0.2-0.4 | Full session | Vibration damping, proprioception |
| Immediately post (0-2h) | 20-30 | Acute swelling | 0.3-0.5 | 1-2 hours | CK reduction ~10% |
| Extended post (2-24h) | 15-25 | DOMS at 24-48h | 0.42 | 12-24 hours | Most studied benefit window |
| Overnight (8h) | 15-25 | Perceived recovery | 0.52 | 8 hours | Best compliance; large perceived benefit |
| Pre-competition | 15-20 | Warm-up / proprioception | Small | 30-60 min | Minimal recovery effect |
| Post-competition (24-72h) | 20-30 | Return to performance | 0.3-0.4 | Extended | Useful for tournament settings |
What the Meta-Analysis Established
Hill et al. (2014 — PMID 24127764) pooled 23 studies and found consistent small-to-moderate effects for DOMS (d=0.42) and perceived recovery (d=0.52). Critically, extended duration wear (12-24 hours) consistently outperformed shorter wearing periods. This makes practical sense: venous return enhancement during the inflammatory phase (which peaks at 24-48 hours post-eccentric exercise) provides more benefit than brief post-exercise sessions.
Engel et al. (2016 — PMID 27106556) confirmed that the pressure range of 15-30 mmHg is effective; consumer garments below 15 mmHg show minimal physiological effect beyond placebo. Athletes investing in compression for recovery should verify actual pressure ratings rather than relying on marketing descriptors like “high compression.”

Frequently Asked Questions
Should compression be worn during exercise or only for recovery?
Different benefits apply. During exercise, compression provides vibration damping, proprioceptive feedback, and may reduce muscle oscillation — effects relevant to muscle damage prevention. Post-exercise recovery use (12-24 hours) targets venous return, edema reduction, and soreness. Both uses have evidence; recovery-phase use shows larger effects for DOMS specifically.
What pressure is needed for recovery benefit?
The therapeutic range is 15-30 mmHg. Consumer athletic compression garments typically provide 15-25 mmHg at the graduated regions. Medical-grade compression (30+ mmHg) is rarely necessary and may restrict comfort during extended wear. The key is graduated compression — highest at the distal limb, decreasing proximally — which is how venous return is enhanced.
Does wearing compression to sleep improve recovery?
Overnight wearing (8+ hours) is among the better-supported protocols in the literature. The extended venous return enhancement during horizontal rest and the continuous mechanical support during the inflammatory phase (24-48h post-exercise) contribute to the modest but consistent DOMS reductions.
Do compression garments actually affect biomarkers or just perceived recovery?
Both, but the subjective effects are stronger. Objective biomarkers (CK, myoglobin, inflammation markers) show modest ~15% reductions. Perceived soreness and fatigue reductions are more consistent and larger in effect size. This pattern is similar to other recovery modalities — subjective experience responds more than objective tissue markers.
Is whole-body compression better than targeted garments?
Not necessarily. Most evidence comes from studies of lower limb compression (tights, calf sleeves) after leg-dominant exercise. Targeted compression matching the exercised muscle groups is the practical standard. There is no strong evidence that full-body compression suits provide proportionally greater benefit.
