Things worth knowing about "Eccentric Training"

Eccentric training is a form of exercise in which muscles lengthen under load. It promotes strength, muscle growth, and is widely used in rehabilitation.

What is Eccentric Training?

Eccentric training is a method of strength exercise in which a muscle lengthens while under tension, rather than shortening. In sports science, three types of muscle contractions are distinguished: concentric contraction (muscle shortens), isometric contraction (muscle length remains constant), and eccentric contraction (muscle lengthens under load). Eccentric training deliberately focuses on this braking, lengthening phase of movement.

A classic example is the controlled lowering of a weight during a bicep curl, or the slow descent during a squat. The muscle must actively resist an external force, generating particularly high levels of mechanical tension within the muscle tissue.

Mechanism of Action

During eccentric contractions, the muscle generates greater force than during concentric movements, even though fewer motor units are activated. This results in higher mechanical stress per muscle fiber and triggers specific adaptive stimuli:

Hypertrophy: Eccentric training is a particularly potent stimulus for muscle growth, as it causes pronounced micro-damage to muscle fibers that are subsequently repaired and reinforced.
Strength gains: The high mechanical tension promotes neuromuscular adaptations that increase maximal muscle strength.
Tendon and connective tissue strengthening: Eccentric loading stimulates collagen synthesis in tendons and fascia, increasing their load tolerance.
Improved muscle architecture: Studies show that eccentric training increases fascicle length, enhancing functional performance capacity.

Areas of Application

Sport and Performance

In sport, eccentric training is used to improve strength, speed, and jumping ability. It is a central component of training programs for track and field athletes, football players, swimmers, and martial artists. Eccentric overload training, using loads above the concentric maximum, is particularly popular in elite sport settings.

Rehabilitation and Physiotherapy

Eccentric training holds a particularly prominent role in rehabilitation. It is successfully applied in:

Tendon pathologies such as Achilles tendinopathy or patellar tendon syndrome (Jumper's Knee)
Muscle injuries and their prevention, e.g., hamstring strains
Knee pain, particularly in cases of patellofemoral pain syndrome
Shoulder problems involving the rotator cuff

The most well-known rehabilitation protocol is the Alfredson protocol for the Achilles tendon, in which eccentric calf muscle exercises are performed systematically over several weeks.

Health and Prevention

Eccentric training is also suitable for older adults or individuals with limited exercise capacity, as it produces high muscular stimuli with relatively low cardiovascular demand. It can help prevent sarcopenia (age-related muscle loss) and improve balance and fall prevention.

Practical Application and Training Planning

Eccentric training is performed in several ways:

Tempo method: The eccentric phase of an exercise is deliberately slowed down (e.g., 3–5 second lowering phase).
Supramaximal training: Loads above the concentric maximum are used, with assistance from a partner or machine during the lifting phase.
Specialized equipment: Eccentric training devices (e.g., flywheel technology, motorized isokinetic machines) allow precise control of eccentric load.
Bodyweight exercises: Exercises such as Nordic Hamstring Curls or single-leg squats use body weight as eccentric resistance.

Training intensity should be individually adapted. Since eccentric training typically causes more DOMS (Delayed Onset Muscle Soreness) than concentric methods, a gradual increase in load and volume is important, especially for beginners.

Risks and Contraindications

Eccentric training is generally safe when performed correctly. However, the following points should be noted:

Higher risk of muscle soreness and temporary strength loss following intense sessions
In cases of acute injuries, inflammation, or recent surgery, eccentric training should only be carried out under medical or physiotherapeutic supervision.
Individuals with severe orthopedic conditions require individualized adaptation of the training program.
