The adductor muscles form a group located on the inner side of the thigh. They bring the leg closer to the axis of the body, a gesture called adduction. Used with each stride, they stabilize the pelvis and participate in almost all sports.
When they are in pain, the discomfort is often located near the groin. Understanding their role helps to train them better and limit the risk of injury.
What are the adductor muscles?
The thigh adductors bring together five muscles attached to the pelvis and femur. They pull the leg inward and control lateral movements. Without them, walking in a straight line or changing support would become unstable.
We also speak of hip adductors, because these fibers act directly on the joint. Their tone keeps the pelvis straight during walking and running.
Anatomy of the thigh adductors
The anatomy of the adductors is based on five muscle heads: the adductor longus, the adductor brevis, the adductor magnus, the pectineus and the gracilis. They arise on the pubis and attach along the femur. The obturator nerve controls most of these fibers.
This organization explains why pain can radiate from the pubis to the knee. A localized tension often provides information on the muscle actually affected. These fibers cover a large area, from the groin crease to the lower third of the thigh.
Adductor or abductor: what's the difference?
The confusion between adductor and abductor often comes up. Adduction brings the leg closer to the body, while abduction moves it outwards. The abductors, like the gluteus medius, occupy the lateral aspect of the hip.
On an indoor machine, the hip adduction movement tightens the knees. Conversely, abduction takes them away. These two families work together to keep a stable pelvis.
Why do we have pain in our adductors?
Pain in the adductor muscles often appears after intense effort or a sudden movement. Accelerations, strikes and changes of direction place these muscles under heavy load. Too short a warm-up further accentuates this risk.
How does adductor pain manifest?
The discomfort is felt especially on the inner side of the thigh, sometimes as far as the groin. Many describe adductor pain in the inner thigh, sharp when pressing or stretching. The slightest deviation of the legs can then wake up the tendon. Depending on the case, the pain remains localized or diffuses towards the inguinal region. A footballer sometimes describes it as a burn when starting.
Adductor pain in athletes
Football accounts for a large proportion of these injuries. Shooting, tackling and repeated presses stress the insertion on the pubis. A breakdown or tear can then occur suddenly.
Running does not spare this muscle group. Many runners report adductor pain after a long ride. The imbalance between adductors and abductors remains a classic cause. Among pivot athletes, these injuries are among the most common muscle injuries.
Pubalgia and adductor tendinopathy
Pubalgia refers to chronic pain in the pubic region and groin. It mainly affects footballers and athletes subjected to violent support. Adductor tendinopathy represents one of the most common forms.
Specialists rely on the Doha agreement to classify these groin pains. This framework, published in 2015, particularly isolates damage linked to the adductors. Today it guides the diagnosis and monitoring of the patient.
Adductor pain in pregnant women
Pregnancy changes posture and relaxes the ligaments of the pelvis. Adductor pain in pregnant women often reflects this adaptation. It remains common at the end of pregnancy, when the weight of the belly pulls forward.
Gentle stretching and light strengthening usually relieve this tension. However, medical advice is required if the discomfort becomes severe or persistent. A support belt and wider supports reduce pressure on the front of the pelvis.
Adductor canal syndrome
More discreet, the adductor canal houses the saphenous nerve on the inner side of the thigh. Its compression causes tingling or pain going down to the knee. This adductor canal syndrome remains rare, but deserves careful examination.
How to treat adductor pain?
Relative rest marks the first stage. Reducing painful movements allows the tendon to recover without completely immobilizing it. Conversely, a recovery that is too rapid often extends the healing time. The cold applied in the first days calms the inflammation.
The diagnosis
A precise clinical examination guides the diagnosis. The practitioner palpates the insertion on the pubis and tests the contraction against resistance. An ultrasound or MRI sometimes confirms the lesion and rules out other pelvic pathologies. The doctor also compares the right side and the left side, in order to identify weakness or asymmetry.
Treatment and physiotherapy
Physiotherapy plays a central role in treatment. The physiotherapist combines progressive work, targeted stretching and appropriate strengthening. Shock waves sometimes complete treatment for chronic forms.
Depending on the duration of the symptoms, adductor pain heals in a few weeks or several months. Regular monitoring clearly reduces the risk of recurrence.
Return to sport safely
The recovery is prepared in stages, without skipping the phases. We first validate the line race, then the changes of support, finally the specific gestures. Guided feedback limits relapse and restores confidence.
What exercises to strengthen the adductors?
Strengthening the adductors is based on a progressive and well-measured load. It's best to start easy, then increase the difficulty over the weeks. This gradual rise protects the fragile insertion on the pubis.
The Copenhagen Adduction
The Copenhagen Adduction has established itself as a benchmark exercise. Performed in lateral support, it solicits the adductors in eccentric mode. Several studies link it to a reduction in groin injuries among football players.
Exercises with or without equipment
The adductor machine, in a seated position, isolates the movement and reassures beginners. An elastic band reproduces this same gesture at home, without a device. On the ground, pressing a ball between the knees already activates the fibers isometrically.
A few adductor exercises often come up in the programs:
- adduction lying on your side, lower leg slowly rising towards the ceiling;
- sumo squat, feet wide apart and toes open outwards;
- the side lunge, which stretches and strengthens the thigh in the same movement.
Adductor stretches
Stretching the adductors maintains the flexibility of the inner side of the thigh. The butterfly position, seated, heels together, remains the simplest to hold. We keep the posture smoothly, breathing slowly.
An adductor stretch held for twenty to thirty seconds prepares you well for the effort. Carried out after the session, it also promotes muscle recovery.
How to prevent adductor injuries?
Prevention begins with a complete warm-up before each session. A few minutes of hip mobility wakes up the muscles and limits lesions. The body responds much better to exercise once prepared.
Balancing the work of the adductors and abductors remains a key point. A group that is too weak compared to the other weakens the pelvis. Varying the exercises and respecting rest times maintains this balance.
To build a safe program, the support of a coach or a professional is a game-changer. An expert eye adjusts the load, corrects the technique and adapts the progression to your level. It is also the best way to return to sport after adductor pain, without relapse.
