Eccentric
This week is 'Eccentric'.
A little anatomy lesson here - there are three (3) types of contractions during muscular movement: Concentric, isometric and eccentric.
Concentric is a contraction that shortens a muscle (for example, during a bicep curl, when you bring the weight up to your shoulder, your bicep is contracting to bend your elbow (or bring flexion into your elbow joint))
Isometric is a hold - when a muscle contraction does not cause a joint to move (like holding a plank)
Eccentric is a lengthening contraction, where the muscles lengthen with control (for example, the second half of a bicep curl, when you lower the weight from your shoulder back to its starting position, your biceps are lengthening but still contracting.) Eccentric contractions often slow the movement down - it's actually where we get a lot of our strength gains and soreness from.
This week, we're focusing on the eccentric portion of contractions and strength training. A lot of what we will do this week will be slow, focusing on the lengthening of the muscles controlling the movement, followed by a short hold and a quick concentric contraction. The goal of this week will be form and corrective exercise (we're taking inspo from the corrective exercise class I'm in right now!).
I'm really excited to bring this corrective exercise practice to you this week - we'll need weights for added umph!
