Compression garments after training: what they actually do for recovery

Compression modestly lowers perceived soreness, but the evidence for meaningfully speeding actual tissue repair is weak

Compression sleeves, tights, and socks are worn after training on the idea that squeezing the limb helps blood and lymph move back toward the heart more efficiently, which in theory reduces the swelling and fluid buildup that follows hard exercise. That mechanism is plausible and reasonably well supported for venous return itself — compression garments do measurably reduce lower-limb swelling in various contexts. The open question is how much that translates into meaningfully faster recovery from a training session.

The evidence that holds up best is for perceived soreness. Several meta-analyses comparing compression garments worn after exercise to no garment find a modest but fairly consistent reduction in reported muscle soreness in the day or two afterward, along with somewhat better perceived recovery scores. People wearing them tend to report feeling less beat up, and that's not nothing — subjective soreness affects motivation and how a session feels going into the next workout, even if it isn't a marker of tissue repair.

Where the evidence gets much weaker is on objective outcomes. Studies looking at blood markers of actual muscle damage, like creatine kinase, or at next-day strength, jump height, and sprint performance, mostly find small or inconsistent effects of compression garments compared to no intervention — some show a slight benefit, many show none. So the realistic verdict is that compression garments are a low-risk, low-cost way to feel less sore and maybe recover a bit more comfortably, particularly useful around long travel or multi-day competition when perceived soreness compounds. They're not a reliable way to actually speed up muscle repair or guarantee better performance the next day, and skipping them costs you little beyond that modest soreness benefit.
