If the braking cannot be reduced to zero, how do we quantify this baseline? If using the force plate, would it be correct to say that we will have the correct mass information when the weight is un-racked? If we are not using the force plate, how do we quantify the contribution of the braking force?
We advise to not use the brake during testing and only attach for training when the load is too high to tolerate without eccentric assistance. However, even when using the brake, the force plate will reflect the ground reaction force and this will include the body weight, brake force and acceleration force components. To get an actual load with the brake attached we just “weigh” the person plus bar using the force plate.
