What role does eccentric exercise play in rehabilitation?

These reviews revealed that eccentric exercise may reduce pain and improve strength in patients with lower extremity tendinopathies, but whether it is better than other forms of rehabilitation has yet to be determined.

Why does eccentric work in tendinopathy?

The most commonly suggested mechanism through which eccentric exercises are believed to have an effect is the application of increased loads to the tendon stimulating structural tendon changes.

What is eccentric rehabilitation?

Eccentric contraction exercises are an important and often overlooked component of strength training. By: Dr. Ashley O’Rourke PT, DPT, ATC, LAT. Eccentric strength refers to tension being applied to a muscle as it lengthens. This is also when the muscle’s force-producing capacity is most optimal.

How do eccentric contractions catalyze muscle growth?

Eccentric Contractions Lowering the weight in a bicep curl elongates or lengthens the muscle, which is part of eccentric strength training. The rate at which actin and myosin detach from one another is greatly inhibited during the eccentric phase, which allows for more contractions and higher force production.

What are the benefits of eccentric training?

How Can Eccentric Exercise Benefit Your Workout?

• Faster muscle gains. Rep per rep, eccentric training is superior to concentric training at building both muscle size and strength, research shows.
• Greater metabolic boosts.
• More flexibility.
• Lower risk of injury.
• Better sports performance.
• One caveat.

What are eccentric exercises?

Eccentric exercises are exactly that; they are slow, lengthening muscle contractions that are for a specific muscle. For example, if you imagine slowly lowering yourself down to sit into a chair, the slow motion of you going from a standing position to sitting is an eccentric contraction, or “negative”.

Are eccentric exercises effective for the treatment of Achilles tendinopathy?

There is some evidence that eccentric strengthening programmes may be effective in the management of tendinopathy of the main body of the Achilles tendon [15, 16]. Graded eccentric exercises regimen was proven to be effective in case–control studies and in prospective randomized control trials [15–19]. Stanish et al.

What is eccentric tendon?

An “eccentric” movement is one that lengthens a muscle/tendon while under tension. An example would be the lowering phase of a push-up. In this example, the tricep and pectoral muscles are lengthening while they are under load.

What happens during eccentric muscle contraction?

An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting (Lindstedt et al., 2001).

Does eccentric contraction cause muscle soreness?

High force eccentric muscle contractions can result in delayed onset muscle soreness (DOMS), prolonged loss of muscle strength, decreased range of motion, muscle swelling and an increase of muscle proteins in the blood.

What are two causes of muscle soreness after eccentric exercise?

The soreness has been attributed to the increased tension force and muscle lengthening from eccentric exercise. This may cause the actin and myosin cross-bridges to separate prior to relaxation, ultimately causing greater tension on the remaining active motor units.

What is eccentric exercise used for in rehabilitation?

Traditionally, eccentric exercise has been used as a regular component of strength training. However, in recent years, eccentric exercise has been used in rehabilitation to manage a host of conditions.

Is eccentric exercise effective for the rehabilitation of tendinopathies?

Abstract. However, in recent years, eccentric exercise has been used in rehabilitation to manage a host of conditions. Of note, there is evidence in the literature supporting eccentric exercise for the rehabilitation of tendinopathies, muscle strains, and in anterior cruciate ligament (ACL) rehabilitation.

Is eccentric training effective in the treatment of muscle strains?

However, evidence is mounting to support its use in the treatment of muscle strains, with most of the rehabilitation literature relating to the use of eccentric training in rehabilitation after hamstring injuries. Finally, eccentric training has been used in recent years as a part of rehabilitation following ACL reconstruction.

What is the best range of motion for eccentric exercises?

Intuitively, eccentric exercises should be initiated in low to middle ranges of motion in order to limit the risk of further injury. Walking lunges, multi-directional step ups, split squats, stiff leg dead lifts, and “modified good mornings” should be implemented within pain free range of motion.
