Compression clothing: does it help recovery?

What the evidence says

The research on sports compression is mixed, and it is worth being honest about that. Some studies and reviews find that wearing compression after hard exercise slightly reduces how sore and tired people feel over the following day or two. Effects on objective measures, such as how quickly strength or sprint performance returns, are smaller and less consistent.

Wearing compression during exercise does little for performance in most studies. Some people like the supportive feel, particularly on the calves when running, and that is fine, but it will not make you faster or stronger.

There are also good reasons to be cautious about the findings. It is impossible to blind people to whether they are wearing tight clothing, so expectation plays a part. The pressure applied varies hugely between products, and many studies use small groups of young, trained athletes. The fair summary: a possible small benefit for how you feel, no convincing benefit for how you perform.

Recovery tights will not undo a poorly planned week of training either. If your legs are constantly heavy, the fix is usually in the programme, your sleep or your food, not in your kit.

When it might be worth wearing

Compression is not a must-have, but there are situations where it is a reasonable choice.

• After a race. Following a HYROX or a long run, pulling on compression tights for the journey home may help your legs feel less heavy. Our guide to recovering after HYROX covers what matters more.
• Long journeys. Sitting in a car, coach or plane for hours after a hard event is when legs feel worst. Comfortable compression socks plus regular movement may help you feel better.
• Long days on your feet. Some people with standing jobs find compression socks make their legs feel less tired by the evening.
• Cold weather. Compression layers under shorts are warm and do not flap about.
• Simple preference. If you like how it feels and it does not cause problems, that is reason enough.

If your main complaint is next-day soreness, remember that compression is a small extra. Sleep, food and gentle movement do most of the work, as our guide to DOMS explains.

Choosing and wearing it

1. Size by measurement, not guesswork. Most brands give charts based on calf, thigh or hip circumference.
2. It should feel firm and even, not painful. Avoid anything that digs in at the top or leaves deep marks.
3. Wear it for a few hours after hard training or racing, rather than all day and night, unless a health professional has advised otherwise.
4. Take it off straight away if you notice numbness, tingling, increased pain, or skin turning pale, blue or very red.
5. Wash and replace it regularly. Compression loses its tightness over time.

Price is not a reliable guide to quality. Some mid-priced garments fit better than premium ones, and fit is what matters most. Buy one pair, try it after a few hard sessions, and only buy more if you genuinely notice a difference.

For race day and training kit more broadly, our guide to HYROX shoes and kit covers what is worth buying and what is not. If you are training for a race through the strength and Engine classes at Lycan Strength, spend on good shoes before you spend on compression.

Who should get advice first

Compression is not suitable for everyone. Tight garments can be harmful for people with poor circulation to the legs, such as peripheral arterial disease, and for some people with diabetes, especially if they have reduced feeling in the feet. Speak to your GP or practice nurse before wearing compression if you have either of these, or if you have fragile skin, leg ulcers or heart failure.

Compression is not a treatment for injuries either. A calf that is sore in one spot after a sudden pull is more likely a strain than general tiredness, and our guide to calf strain explains what usually helps.

Know the signs of a blood clot

Long journeys after a hard race, dehydration and immobility all slightly increase the risk of a deep vein thrombosis (DVT), a clot in a leg vein. It is uncommon in healthy active people, but it matters to recognise the signs, and compression socks do not make you immune.

• Throbbing or cramping pain in one leg, usually the calf or thigh, that is not like normal muscle soreness
• Swelling in one leg
• Warm skin around the painful area
• Red or darkened skin, which may be harder to see on brown or black skin
• Swollen veins that are hard or sore to touch

If you notice these, contact NHS 111 or your GP urgently. If you also have chest pain or sudden breathlessness, call 999, as a clot may have travelled to the lungs.
