Creating force is essential in every form of exercise, which is why it is included in this study’s analysis of muscle torque. Therefore, torque is defined as a force that is applied to an object, normally perpendicularly to a lever, so that it causes rotation (T=F⫠ × d_(axis of rotation)) (Lawler, 2018).
