Concentric contractions are movements that cause your muscles to shorten when generating force. In weight training, a bicep curl is an easy-to-recognize concentric movement. Learn concentric ...

A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. For example, when doing a sit-up, your muscle shortens and generates enough force to ...

This week, I'll talk a little about how contraction time works, and how to maximize it. Plus, I will introduce an exercise that demonstrates this concept very well.

5 Equipment-free exercises to strengthen the hamstring, one of the most important and injury-prone muscles for running.

As an example of concentric contraction, imagine the curling action of a bicep curl. The eccentric motion would be the uncurling phase of the exercise. Mind-muscle connection benefits: injury ...

During an exercise, when your muscles are activated, they can either contract while shortening (a concentric contraction), lengthening (an eccentric contraction), or without changing in length (an ...

Concentric contractions are the foundation of most strength exercises. You need to be able to move a load to build strength, and the concentric phase is where that effort happens, Chang says.

This type of muscle contraction generates 10-40 percent more force than concentric muscle contractions (muscle shortening exercise) with less work.

Thus, the present findings suggest that eccentric exercise is not more aggressive than concentric exercise when respecting the maximum limit of the individual.
