Rollers, ice and compression: what each one actually does

There’s a whole industry around recovery: foam rollers, massage guns, ice baths, compression socks, pressure boots. The useful question isn’t whether they work, but what exactly they improve.

What the meta-analyses say

They agree with each other fairly well. Foam rolling reduces perceived muscle soreness by a small but consistent amount, and its effect on performance is close to nothing. Cold water reduces perceived soreness and swelling. Compression reduces perceived fatigue and some swelling.

Being “only” a feeling doesn’t make it useless: feeling better the next day is the difference between going out and not going out, and going out is what trains you. But it’s worth buying with your eyes open.

A caveat about cold

Cold water after strength training may interfere with part of the adaptation you were after: inflammation isn’t only damage, it’s also the signal that triggers improvement. If the day included a strength session and you want that session’s benefits, an ice bath isn’t the best idea.

What actually recovers you and isn’t for sale

• Sleep. It’s the only one with a large effect, and it’s free.
• Eating enough. You can’t recover from a load you don’t feed.
• Easy days that are genuinely easy. Most people who don’t recover aren’t missing a foam roller: their easy days aren’t easy.

What to do tomorrow

• If the roller relieves you and you enjoy it, use it. Don’t expect it to make you faster.
• Before spending on recovery, look at how much you sleep and how much you eat.
• Save the ice bath for race days or very high load, not as routine after strength work.
