so what determines Force production versus velocity is what we call cross Bridges so the amount of time that these meas and heads grab onto that little place of connection is called a crossbridge the more those cross Bridges you have the more effectively you can pull the AC in closer to each other the the more effective you do that the faster the contraction the more forceful the contraction is going to be so primary thing explaining Force production is the amount of cross Bridges so the thicker your myosin the more likely you are to grab actin the faster the stronger the hold if you will so the better connection your hand has to that thing it's grabbing on to rather than you can imagine like a couple of fingertips on it and trying to pull something closer to you versus having your whole hand wrapped around it a strap on it chalk on it and like you're gonna be able to rip that thing down quickly
