Isometric bench press strength were performed using the FT700 Plyometric Power System (Fitness Technology, Skye, SA, Australia), which includes a position transducer and magnetic braking system. Two force plates (Type 9286, Kistler Instrument Corporation, Amherst, NY) were placed under the bench to measure force output during testing. During the bench press strength test, the bar was placed on top of adjustable safety stops provided by the manufacturer. The positions of the stops were adjusted so that the bar was as close to the subject’s chest as possible without coming into contact with the subject. The position of the bar was then fixed using adjustable mechanical stops.
During the bench press maximal power test, the upper mechanical stops were removed and the bar rested against the bottom stops. Subjects began the maximal power test with the bar resting on mechanical stops above their chest and then, on command, performed 21 consecutive maximal ballistic repetitions. A magnetic brake (Fitness Technology, Skye, SA, Australia) caught the bar as soon as it reached its peak height and then lowered the bar back to the starting position so that no eccentric muscle actions were performed by the subject.
