Cupping Therapy for Badminton: What the Evidence Shows

Last checked: August 2026 · Written by the Badminton House player-led team.

The round marks seen on athletes can make cupping look like a measurable treatment: more colour appears, so something important must have happened. That conclusion goes beyond the evidence. Cupping certainly applies suction and can alter the skin’s appearance. Whether it changes the outcome that matters to a badminton player—comfortable movement, safe training capacity or performance—is a separate question.

This guide does not tell you to have cupping or avoid it in every circumstance. It separates the known procedure and risks from the claims that have not been established, then gives you a practical way to keep a recovery choice from replacing an injury decision.

What does cupping actually do?

Cupping places a cup on the skin and creates suction. In dry cupping, the skin is not deliberately pierced. Wet cupping adds small skin punctures so blood is drawn into the cup. Those are different procedures with different exposure and hygiene considerations.

The US National Center for Complementary and Integrative Health describes both methods and says most cupping research is low quality. It reports that evidence for pain reduction is not very strong and that there is not enough high-quality research to draw conclusions about other conditions. That evidence boundary matters: a plausible sensation or a long tradition is not the same as proof of faster tissue healing or better sport performance.

An individual may notice a change in comfort afterward, but that subjective change does not establish mechanism, duration or performance benefit. Treat it as one observation. Do not turn it into a diagnosis, a detoxification claim or permission to ignore a movement that remains painful.

What does the athlete research show?

Athlete-specific evidence is too uncertain to promise better recovery or performance. The available trials use different procedures, body areas and outcomes, and many have methods that make confident conclusions difficult.

A systematic review of cupping in amateur and professional athletes found 11 randomized trials with 498 participants. The interventions and measured outcomes varied, most studies had unclear or high risk of bias, and none reported safety outcomes. The reviewers concluded that the evidence did not support a recommendation either for or against cupping in athletes.

That is not evidence that cupping never helps anyone feel better. It means the research cannot tell a badminton player that cupping will restore smash power, remove post-match fatigue, prevent a strain or shorten a safe return-to-court timeline. Those are distinct outcomes, and the review does not establish them.

What do cupping marks mean, and what are the risks?

Circular red or purple marks are compatible with suction-related skin changes. A dermatology report on suction purpura explains that negative pressure can produce petechiae or ecchymosis—small spots of bleeding or a bruise-like area beneath the skin. The cited sources describe the marks as skin findings; they do not provide a validated way to use their appearance to judge recovery.

Cupping is not risk-free. NCCIH lists persistent skin discolouration, scars, burns and infections, and says it may worsen eczema or psoriasis. Wet cupping adds broken skin and blood exposure. Equipment contaminated with blood can spread bloodborne disease if it is reused without proper sterilization.

Because this is a procedure, provider training, hygiene and your own medical context matter. This article cannot evaluate a practitioner or tell you that cupping is appropriate alongside a condition, medication or skin problem. If you are considering it, discuss those individual factors with an appropriately qualified health professional.

How should a badminton player make the decision?

Start with the symptom, not the modality. General post-session heaviness that is already settling is different from pain that began during a lunge, visible swelling, loss of strength, instability or an inability to move normally. If a symptom changes your footwork, do not use cupping marks or temporary comfort as evidence that the court is safe.

1. Name the goal: comfort is a different goal from healing an injury or improving performance.
2. Record the baseline: note the symptom and the movement it affects before any recovery treatment.
3. Keep training decisions separate: judge court readiness from normal function and appropriate clinical advice, not from a change in marks or sensation.
4. Stop when the question changes: worsening or disabling symptoms are an assessment problem, not a recovery-modality comparison.

Seek urgent assessment for very severe or worsening pain, substantial or worsening swelling or bruising, marked difficulty moving, or an inability to bear weight or walk more than a few steps. A crack at the time of injury, deformity, numbness or tingling, or blue, grey or cold skin needs emergency help, according to NHS sprain and strain guidance.
