50-Year-Old Assumptions About Muscle Strength Tossed Aside
vinces99 writes "The basics of how a muscle generates power remain the same: Filaments of myosin tugging on filaments of actin shorten, or contract, the muscle – but the power doesn't just come from what's happening straight up and down the length of the muscle, as has been assumed for 50 years. Instead, new research shows that as muscles bulge, the filaments are drawn apart from each other, the myosin tugs at sharper angles over greater distances, and it's that action that deserves credit for half the change in muscle force scientists have been measuring."
Rock anchors expand into the drill hole and thus secure the rod in place. So with muscles, part of the "strength" is from just not letting go. Also brings to mind that wood fibers are made of two quite different ingredients -- long strong fibers, and good "matrixy" glue.
I come here for the love
Don't be too harsh on him. Some of us appreciate the fact that he took the time to read the first line or two and craft a troll comment that demonstrates his awareness of the topic at hand, rather than copy/pasting some cookie-cutter comment that doesn't have an ounce of creativity to it. Handcrafted trolling, particularly the sort that makes use of pre-Internet memes such as "your mother", is a dying art that should be valued in all of its forms.
Come on! Even in the '70s in every clip you could hear Arnold shouting "Ze Myocin tugz at Shahpahh angles!" Of course he was stoned out of his gourd when he said that.
