The Benefits of Eccentric Exercise

What is Eccentric vs. Concentric Muscle Contraction?

Eccentric vs. Concentric Muscle Contraction

Concentric Contraction: Concentric contraction occurs when a muscle is activated and begins to shorten against a load.  The raising of a weight during a biceps curl is a concentric contraction.

Eccentric Contraction: Eccentric contractions occur when the muscle is lengthening during contraction.  The lowering of the weight slowly during a biceps curl is an eccentric contraction.  Eccentric contractions occur constantly throughout the activities of daily living.  During movements such as walking the quad muscles stabilize and control the frame of the body while they are actively contracting and lengthening.

The Importance of Eccentric Contraction:
Sports Medicine research has shown that eccentric contracts are better at building muscle mass, strengthening and repairing connective tissue including tendons and ligaments.   There is evidence that eccentric contractions even help increase flexibility.  

For minor injuries and tendonitis conditions your practitioner may prescribe eccentric exercises as a home care therapy.  The practitioner will explain the exercise carefully in order to fully take advantage of the eccentric phase of contraction.  Moving very slowly and controlled during the contraction is essential to maximizing the benefit of the exercise.  Moving too quickly or using too heavy a weight can actually damage the tissue.  


Healing a Rotator Cuff Injury

Four muscles form the rotator cuff, the Subscapularis, Infraspinatus, Teres minor, and Supraspinatus. These muscles all protect the shoulder and provide it with great range of motion.

A rotator cuff injury can happen to any one of these muscles' tendons.  Pain from a tear leads to restricted shoulder movement.  Tears can occur from injuries or can be caused by "wear and tear" from regular use of the shoulder.  The most common tear is to the Supraspinatus tendon at the top of the shoulder.

At Inner Gate Acupuncture we use orthopedic testing to determine exactly which muscles and tendons are affected and prescribe a treatment plan to help you get full use of your shoulder as quickly and non-invasively as possible.  If we determine that you're tear is too substantial for acupuncture treatment to be effective we will refer you to trusted clinicians for imaging and other options.

Rotator Cuff Injury

If you had a rotator cuff injury and your shoulder has been surgically repaired, acupuncture can help advance the recovery by increasing blood flow, reducing scar formation, and encouraging the full recovery of normal range of motion.
