Conic pulleys have two types of load settings that will vary the machine’s response to the athlete’s application of force:
-Varying the moment of inertia: the moment of inertia is defined as the minimum value of force that the athlete has to apply to vary the machine´s state of rest, this means that the higher this value is, the more force the athlete has to apply to start and stop the machine, and the more time he will need to stop the machine and start it again (slower the Eccentric/Concentric transition)
– Varying the axle radius: the conical axle in an inertial machine has the same objective as the gearbox of our car, to facilitate the ability to accelerate with the same application of force. As we raise the position of the rail and reduce the radius of the axis, we reduce the capacity to accelerate the machine, making the movement slower and this allows us to increase the time of tension during the exercise.
