Introduction. Eccentric muscle contraction (lengthening) occurs when a force applied to the muscle exceeds the instantaneous force generated by the muscle itself, resulting in forced lengthening of the muscle-tendon system during contraction (Lindstedt et al., 2001).
What does eccentric mean in training?
Eccentric exercises are just those slow, lengthening muscle contractions that target a specific muscle. For example, if you imagine slowly lowering yourself into a chair, the slow motion of your movement from a standing to a sitting position is an eccentric or “negative” contraction.
What are examples of eccentric exercises?
Examples of eccentric exercises include:
- Lower the bar toward your chest on the bench press.
- Descend into a parallel squat position in a crouch.
- In a push-up, go all the way down.
- Bring a barbell down at the end of a deadlift.
- Lower your torso to the floor in a sit-up.
What are eccentric contractions used for?
In an eccentric contraction, the external force exerted on the muscle is greater than the force that the muscle can generate, therefore the elastic series elements are also forced to lengthen due to the high external load. This mechanical energy can be recovered during contraction, providing greater force.
Why are eccentric muscle contractions stronger?
Theories as to why strength gains occur after eccentric loading include increased neural stimulation to and within the muscle, higher stored elastic energy in the muscle, and increased muscle hypertrophy. Neural stimulation in the muscle from eccentric training causes greater stretching of the muscle spindle.

What is the eccentric phase of training?
An eccentric movement is the downward part of a movement. It’s when your muscles work the way they’re stretched, like your glutes when lowering into a squat, or like your biceps when lowering a barbell after a curl. Finally, every muscle fiber in your body is the strongest because it moves eccentrically
What is the difference between eccentric and concentric training?
There are 2 types of isotonic contractions: concentric and eccentric. In a concentric contraction, muscle tension increases to meet resistance and then remains stable as the muscle shortens. With eccentric contraction, the muscle lengthens when the resistance becomes greater than the force generated by the muscle.
What is a concentric exercise?
Concentric Contraction Exercises Concentric muscle contractions involve movements that shorten your muscles. During exercise, concentric movements target muscles to perform an action. The heavier the object you want to lift or move, the more force will be generated.
What are the best eccentric exercises?
Good news: Almost any exercise can be performed with eccentric focus, so you can start incorporating this type of workout into any strength training routine. I recommend the basics to start with: squats, deadlifts, push-ups, and rows, says Guglielm
What is an example of a concentric exercise?
A concentric contraction is a type of muscular contraction in which muscles shorten while generating force and overcoming resistance. For example, when lifting a heavy weight, a concentric contraction of the biceps would cause the arm to bend at the elbow and lift the weight toward the shoulder.
What is an example of an eccentric?
Eccentric is defined as someone or something that is different or behaves in an unconventional way. An example of an eccentric is an adult wearing football pajamas to a formal dinner. Don’t have the same center.
Why is the eccentric phase strongest?
In fact, eccentric contractions actually absorb (mechanical) energy, which is then used in the form of heat or elastic recoil for the next movement. This powerful training phenomenon leads to increased endurance, which develops more strength and therefore more power.
Are muscles stronger eccentrically or concentrically?
The muscles are stronger during eccentric contractions than during isometric and concentric contractions. After an eccentric action, muscle strength is increased – a phenomenon called residual strength enhancement (RFE).
Why are eccentric contractions stronger than concentric ones?
During an eccentric contraction, the muscle tries to shorten by creating tension, but it actually lengthens. This is because the external force exerted on the muscle overcomes the force generated by the concentric contraction.
Which muscle contraction is the strongest?
The eccentric contraction is the strongest type of contraction your body can produce during active movement. Studies show that an eccentric contraction can generate up to 20% more force than a concentric contraction
