![]() What Kinds of Torque are Present in the Deadlift? The neuromuscular system can create torque at each possible action of a joint. In what joint, and in what direction are you creating torque? For example, at the hip, you can create 6 different types of torque, including hip extension torque, hip flexion torque, hip abduction torque, hip adduction torque, hip external rotation torque, and hip internal rotation torque. Simply mentioning that you’re “creating torque” isn’t sufficient. Larger muscles are capable of producing greater muscle force and therefore creating more torque, and tendon insertion points farther away from the joint centers have greater leverage and can therefore produce greater torque.īiomechanical Explanations of Torque Require a Joint and an Action In other words, when muscles contract, they pull on bones rather linearly which creates rotational forces, or torques, around the various joints of the body. In biomechanics, muscles exert forces which create joint torques. Do a combination of both, increase force and the lever arm distance.Exert the same force onto the wrench but further away from the pivot.There are three ways to increase the torque output of the wrench: Torque is sometimes reported in pound-inches to make it more “American-friendly,” but the point is that it’s dependent on both the magnitude and distance away from the pivot of force production. Torque is turning force, and can be thought of as linear force’s rotational analog. While force is usually measured in Newtons, torque is usually measured in Newton-meters, which you can think of as the amount of force exerted perpendicularly to the wrench one meter away from the pivot (which one be one long-ass wrench but hopefully you get the point). However, since there’s a pivot, the force creates torque about that pivot. Force is a vector quantity because it must contain a direction. ![]() ![]() If I push against a wall, I exert force against that wall. I’d like to discuss my thoughts on this topic, but before I do I want to mention that I have tremendous respect for Kelly and Mark, so this is nothing personal.Īnd also before I get started, let me briefly touch upon torque for those who need a brush-up on their biomechanics. Kelly Starrett and Mark Bell are two proponents of this. Lately, there have been many experts suggesting that for optimal squatting and conventional deadlifting performance, one should purposefully create torque by screwing one’s feet into the ground.
