Eccentric Contractions

quads

I just took my dog for a long walk.  If you have a dog – take your dog for long walks.  If both you and your dog had a stroke – take your dog for long walks.  I live in Pittsburgh so everywhere you go there’s gonna be a hill.  You can’t avoid walking on a hill here.  It’s harder for me to go downhill.  It’s harder for everyone – even people without massive brain injuries or ruptured ACLs.  Going downhill is usually harder.

Here’s why.

Think of your right leg lifting your whole body up a step.  To do this the quadricep muscle, the big muscle on the front of the thigh, is getting SHORTER because the part of the muscle attached to the thigh bone is getting closer to the part of the muscle attached to the lower leg bone.  This is a CONCENTRIC contraction.  An ECCENTRIC contraction is just the opposite.  Now think of your right leg going down a step.  That same muscle group, the quads, controls this movement by getting LONGER.  When the body is lowered down a step, the part of the quadricep attached to the thigh bone is getting further away from the part of the muscle attached to the lower leg bone.  So walking down a hill involves a lot of eccentric contractions and eccentric contractions are usually going to be harder.  So how do you get better at performing eccentric contractions?  Do them.  This is meant for physical therapists but has a ton of ideas
