You're lifting weights. The first time feels easy, but each lift takes more and more effort until you cant continue. Inside your arms, the muscles responsible for the lifting have become unable to contract. Whats going on? Christian Moro explains how exactly our muscles operate, and what causes them to become fatigued. Lesson by Christian Moro, directed by Nichola Latzgo

muscles only use atp when relaxing, not while contracting. Thats why rigor mortis sets into a deceased body. The muscles not longer have atp to re balance electrolytes, and thus can no longer relax. They contract, stiffen, and hold until the fibers break down enough to force relaxation.

This is SO very cute! And educational. These videos are a great help to adults like me, who forgot a lot of stuff from school, and can refresh all that knowledge while chilling and relaxing. I love how kindly the voice sounds. This style, in general, encourages to learn (or re-learn) more

A good explanation. Yet you forgot to include CTP(creatine triphosphate) a source of energy only found in muscle cells which gives a serious advantage to other tissue. TED is prized because of its inclusion of such important and interesting details. Keep up the good work.

When you're reminded that pleb english speakers call element K potassium instead of Kalium, and element Na sodium instead of Natrium.

We actually learn this in university. The video makes it so easy to understand. Only missing is the microtome, high resolution microscopy.
