Today I’m going to talk about the differences between concentric contraction and eccentric contraction, And how you can involve them into your workout.
As muscles contract they pull on tendons which pull on bones, This creates movement in the specific area. There are two types of main contractions, concentric contraction and eccentric contraction. When the muscle shortens it is a concentric contraction. When the muscle lengthens it is called a eccentric contraction. When you do a bicep curl it is shortening the muscle which is a concentric contraction, and when you lower the dumbbell in a bicep curl that is a eccentric contraction. Concentric muscle contraction are used to accelerate your-self, we use it to jump, kick, run, tackle. Eccentric muscle contraction are used to decelerate you or an object. Involving eccentric muscle contraction in your workout is as simple as slowing down the movement when gravity is involved, or the negative motion of the lift. Instead of dropping the weight down after doing the concentric motion of a lift go slow and controlled, this will increase the time under tension of the muscle. This enhances protein synthesis, which in the end builds more muscle.
