Acute Effects of Vibration Versus High-Intensity Resistance Conditioning on Neuromuscular Performance

The purpose of this randomized crossover study was to compare the immediate effects of high-intensity resistance conditioning and whole-body vibration conditioning on lower- and upper-body neuromuscular performance in recreationally resistance-trained young adults. Twenty participants were enrolled, and 19 completed both experimental conditions. After a preliminary assessment and familiarization session, participants completed the resistance-conditioning and vibration-conditioning protocols in a randomized order during two experimental sessions separated by 24 hours. The resistance-conditioning protocol included three squat repetitions at 90% of estimated one-repetition maximum before countermovement jump testing and three bench-press repetitions at 90% of estimated one-repetition maximum before an isometric push-up assessment. The vibration-conditioning protocol included lower- and upper-body vibration exercises performed on a vibration platform before the corresponding performance assessments. Lower-body performance was assessed using countermovement jump height, flight time-to-contraction time ratio, and relative peak power. Upper-body performance was assessed using peak force during an isometric push-up. All performance outcomes were measured using dual force desks.
