AB The aims of this study were to compare the force profile of using a horizontal cylinder-shaped axis ora vertical cone-shaped axis to provide resistance in rotary inertia devices, and to report the evolution ofkinetic and kinematic variables in experienced athletes during a half-squat exercise. Twenty-two healthyactive men participated in the assessment of time, peak velocity, peak force, time to reach the peak force,average force, impulse, and range of movement, during a half-squat incremental test performed onconical inertial device (CP) and on cylinder inertial device (YY). The analysis showed that YY during CONECCphased generates substantial higher peak_force, mean_force, impulse, time, and a lower peak_velocity,than CP. We never obtained eccentric overload for peak_force or mean_force. CP offers lessresistance to accelerate-decelerate the movement with respect to YY, we need checking whethereccentric overload it is being produced, and the impulse was the only kinetic variable that was able todiscriminate between the inertias and devices.
