Cupping in sports massage: what research shows — and what it does not

Cupping returned to Western attention after the Rio Olympic Games, when cameras lingered on the marked backs of some swimmers. Since then the technique has been everywhere, and with it a quantity of promises that are rarely checked. Competition images show a gesture. They do not say what research allows us to conclude, nor what a wellbeing session can honestly offer.

I use cups in session, occasionally, when the muscular work justifies it. Here is what you need to know before deciding whether it interests you, including what argues against it. This text distinguishes three planes: the local mechanical effect, what studies have observed, and what I actually do in my practice in Cannes.

What happens mechanically

The difference with massage is one word: direction.

Under the hands, tissues are compressed inwards. Under a cup, it is the reverse. The depression created in the bell visibly lifts the skin and the layers beneath. That is why the technique is also called myofascial decompression. The word describes a gesture, not a diagnosis and not a guaranteed clinical result.

The best-documented effect is local. A study using laser Doppler measured, after placement, peaks of cutaneous blood flow several times above the starting value; intensity varied with the pressure applied and the duration. This is a real, measurable effect, limited to the area worked. The experiment was conducted in a narrow experimental setting, on the skin, not on a competition field. It does not allow a conclusion of a general “boost” to circulation, nor a clinical effect beyond that local observation.

Two ways of working. Stationary cups stay a few minutes on a precise area. Moving cups travel along the muscle on oiled skin, in a continuous movement. The second method is the one I use most often, because it fits the rhythm of a session instead of interrupting it. In both cases, the diameter of the bell, the time of placement and the amount of suction change the sensation. A smaller diameter suits a narrow area; a wider diameter spreads the depression over a larger surface. This is not a single formula, and it is not a medical dosage.

What the research shows

In athletes, a systematic review of randomised trials published in the Journal of Alternative and Complementary Medicine noted signals on perceived pain, on joint range and on some blood markers associated with muscle fatigue, compared with groups that received no treatment.

On back pain, several meta-analyses report a reduction in pain, with results that vary widely according to the type of low back pain studied and the method used. A 2024 synthesis on low back pain, for example, gathers heterogeneous trials: protocols, comparators and populations are not superimposable. Reading “a drop in pain in some studies” is not equivalent to “cups treat the back”.

These readings describe what some studies have observed. They do not turn cups into a validated treatment, and they say nothing, on their own, about what happens in a sports massage session in Cannes. They also do not allow us to transfer to cups the effectiveness sometimes documented for massage in general: the tool is not isolated, and the setting is not the same.

What the research does not show

This is the part most websites omit, and it is the part that matters.

The authors of the review on athletes themselves conclude that no explicit recommendation can be made, for or against. Most trials presented a high or unclear risk of bias, and none reported safety data. In other words: signals exist, the method of the trials is often fragile, and one cannot use them as proof of sports recovery.

On low back pain, there is a Cochrane review protocol (CD015269) devoted to cupping in chronic non-specific low back pain.

A Cochrane protocol describes the method of a forthcoming review. It is not a completed review, and it does not allow any clinical conclusion.

Other analyses already published remain heterogeneous; some find no significant effect on chronic low back pain. A broader evidence map on cupping shows mainly an uneven field, with questions still open rather than a therapeutic consensus.

Part of the medical community considers that the available evidence does not justify presenting cupping as care. In the frame of this article, I do not present it as a medical act. Questions of reimbursement, nomenclature and official recognition belong to your scheme and to an administrative or medical opinion, not to a practice text.

What I offer belongs to wellbeing, not to medical care. I do not claim to treat any pathology. General studies on massage do not, either, allow a specific clinical effectiveness to be attributed to cups.

Marks on the skin

They surprise people, and they deserve a cautious explanation.

Suction can cause a temporary change in skin colour, tenderness, slight swelling, or marks similar to bruises. Unsuitable use can go as far as blisters, burns or infection. The appearance of the mark does not allow a diagnosis. One does not “read” an organ, a toxin or a clinical gravity in a stain.

These traces usually fade over a few days, faster in some people than in others. They are visible. If you have an event, a photo session or a competition in the days that follow, tell me before the session and we adapt: we can reduce the time, change the area, or not use the tool. Visibility is not an objective. It is not proof that the work “worked” either.

Safety and limits

When they are practised with clean equipment and a reasonable duration, dry cups are most often associated, in the synthesis literature, with minor and transient adverse effects. The more serious incidents reported almost always concern excessive durations, unsuitable equipment or an incorrect method. StatPearls reminds us that the gesture is not trivial once hygiene, time or indication leave cautious use.

I use only dry cups, in silicone, for individual use and disinfected between each person. I do not practise hijama, the version with incision, which belongs to another frame and carries other risks. Wet hijama is not “the same technique with a little more intensity”: the incision makes it a distinct invasive practice.

This article concerns only dry, non-invasive cups, used in a wellbeing practice: without incision, without diagnosis and without a therapeutic promise. This is not a legal opinion. Every practitioner must respect hygiene, insurance, the frame of her practice and the legal orientation that applies to her situation. I do not assert a general legality, valid for every status and every use in France.

Some situations require abstaining or obtaining prior medical advice. The list that follows is not exhaustive: anticoagulant treatment, clotting disorders, a skin lesion on the area concerned, pregnancy, phlebitis, cancer under treatment. If you are in one of these cases, or in another health situation that concerns you, speak to a health professional before any session. Wellbeing does not replace medical follow-up.

How I use them

Cups are not a service I sell. They are a tool among others, in the same way as bamboo, hot stones or hot oil. They have no separate price, no duration sold apart, no “cupping protocol” detached from the session.

I integrate them into a sports massage session when an area remains dense after manual work, or when someone arrives after intense effort. The time given to the tool stays short. I start with the hands, because the hand reads density, heat and tolerance. The cups, if they come in, come afterwards, on an area already worked, with suction that I adapt to what the skin and the person can bear that day.

They never replace the work of the hands. They complement it, in a session built around what the body asks. If the technique does not put you at ease, the session goes ahead without it, and nothing is lost. You can say so before, or during: we stop. The aim is not to obtain a mark, nor to reproduce a competition image. The aim is local, cautious work, within the limits of a wellbeing practice.
