[upd] | Adductors Muscle

The adductor group of the proximal thigh is often overlooked in favor of larger, more superficial muscles such as the quadriceps and hamstrings. However, these five muscles (pectineus, adductor brevis, adductor longus, adductor magnus, and gracilis) serve as the primary stabilizers of the pubic symphysis and the hip joint in the frontal plane. In sports requiring rapid changes of direction (e.g., soccer, ice hockey, basketball), adductor strains account for 10-20% of all lower extremity injuries (Werner, 2019).

| Muscle | Origin | Insertion | Innervation | Primary Action(s) | | :--- | :--- | :--- | :--- | :--- | | | Superior pubic ramus | Pectineal line of femur | Femoral nerve (L2-L3) | Adduction, Flexion | | Adductor Longus | Pubic tubercle | Middle linea aspera | Obturator nerve (L2-L4) | Adduction, Flexion, (Weak IR) | | Adductor Brevis | Inferior pubic ramus | Proximal linea aspera | Obturator nerve (L2-L4) | Adduction, Flexion | | Adductor Magnus | Inferior pubic ramus, ischial tuberosity | Gluteal tuberosity, linea aspera, adductor tubercle | Obturator (L2-L4) & Tibial (L4-S1) | Adduction, Powerful Extension | | Gracilis | Inferior pubic ramus | Pes anserinus (medial tibia) | Obturator nerve (L2-L3) | Adduction, Knee Flexion, Hip Flexion | adductors muscle

By widening your stance and pointing your toes out, you shift the load from the quads to the inner thighs. The adductor group of the proximal thigh is
