Adductor Muscles

Hip Adductor Muscles:

5 Hip Adductor Muscles:

• Pectineus, adductor brevis, adductor longus, adductor magnus, and gracilis.

Introduction to Hip Adductor Muscle Anatomy:

• Lesson 15: Hamstrings and Adductors

Adductor Techniques:

• Release: Anterior Adductor Foam Rolling
• Vibration Release: Adductor Vibration Release
• Manual Release: Static Manual Release of the Anterior Adductors
• Stretch: Standing Anterior Adductors Static Stretch
• Subsystem Integration: Anterior Oblique Subsystems

Adductor Symptoms:

• Feeling of hip adductor muscle pain, tightness, and weakness are not uncommon. Generally, these feelings are the result of hip, sacroiliac joint, or lower extremity issues that should be addressed with an integrated program. For example, often adductor strength is best addressed with hip mobility techniques and gluteus medius activation exercises (Sample Program Below).

Course Summary

Structure:

This course describes the anatomy and integrated function of the adductor muscles group (a.k.a. hip adductors, inner thigh muscles, medial thigh muscles, or muscles of the medial compartment of the thigh). This group is comprised of 5 muscles with much of their mass lying superficial on the medial thigh from the pubis (and ramus of ischium) to the knee, along the length of the medial femur. The adductors are a very large muscle group, comprising 22.5% of the mass of the lower extremity (the only group that may be larger is the combined mass of the gluteus maximus, gluteus medius, and gluteus minimus). The available research suggests that the adductors are composed of far more Type I muscle fiber than Type II muscle fiber.

Function:

The adductor muscle group is comprised of 5 muscles: pectineus, adductors brevis, adductor longus, adductor magnus, and gracilis. Functionally, these muscles may be divided into the posterior adductor magnus with a unique set of functions, and the anterior adductors which include all of the other adductor muscles which perform similar functions. All of the adductors cross the hip, and all may contribute to hip adduction. The posterior adductor magnus will contribute to hip extension and external rotation, and the anterior adductors will contribute to hip flexion and internal rotation. The gracilis crosses the knee and may contribute to knee flexion and internal rotation (as part of the pes anserinus group). This course also describes the role of the adductors during hip arthrokinematics , fascial integration, postural dysfunction, subsystem integration , and synergistic function. For example, the anterior adductors contribute to lower extremity internal rotation and flexion in synergy with the anterior oblique subsystem which aids in rotating the kinetic chain inward, during a wood chop exercise .

Practical Application:

Sports medicine professionals (personal trainers, fitness instructors, physical therapists, massage therapists, chiropractors, occupational therapists, athletic trainers, etc.) must be aware of the integrated function of the adductors for the detailed analysis of human movement, and the development of sophisticated exercise programs and therapeutic (rehabilitation) interventions. For example, altered activity and length of the hip adductor muscles may contribute to groin pain, groin strain, hip joint impingement, low back pain, excessive knee valgus, and knee pain. Altered adductor activity may also result in a reduction in gluteus maximus and gluteus medius activity, resulting in a significant decrease in lower body speed, agility, and strength, and a reduction in the effectiveness of resistance training routines intended to improve lower body strength and hypertrophy (bodybuilding). Deeper knowledge of adductor anatomy is essential for optimal assessment, intervention selection, and building a repertoire of adductor-specific techniques.

This Course Includes:

This course also provides detailed descriptions of etymology, attachments, innervations, joint actions, location, palpation, integrated actions, arthrokinematics, fascial integration, subsystem integration, postural dysfunction, assessment, clinical implications, and interventions.
