Eccentric exercise vs. concentric exercise “Eccentric and concentric exercises are just two parts of any movement,” explains Mike Julom, ACE-certified personal trainer, CrossFit athlete, and ...
For most gym-goers, Nelson says, the best bet is to focus on bringing control to the eccentric portion of a movement, then a forceful, fast concentric to finish a rep. Lowering the weight under ...
Eccentric behavior is often considered whimsical or quirky, although it can also be strange and disturbing. Many individuals previously considered merely eccentric, such as aviation magnate Howard Hughes, have recently been retrospectively diagnosed as having had mental disorders (obsessive–compulsive disorder in Hughes' case).

With delayed onset muscle soreness (DOMS) caused by eccentric exercise (muscle lengthening), it was observed that light concentric exercise (muscle shortening) during DOMS can cause initially more pain but was followed by a temporary alleviation of soreness with no adverse effects on muscle function or recovery being observed.
This movement has also been described as negative training. This "negative" movement is necessary to reverse the muscle from its initial trajectory. [1]When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy.
Both concentric and eccentric movements have advantages in training, which is why most weight lifters perform both for set times. [ 5 ] With all forms there is an obvious backward lean relative to normal running's forward lean, which can shift the stress of the other muscle fibres a small degree.

A negative repetition (negative rep) is the repetition of a technique in weight lifting in which the lifter performs the eccentric phase of a lift. [1] Instead of pressing the weight up slowly, in proper form, a spotter generally aids in the concentric, or lifting, portion of the repetition while the lifter slowly performs the eccentric phase for 3–6 seconds.
