Abstract

The quality of the fencers´ actions in competition will depend primarily on two of the systems involved in the process: the activation of the neural system and the response of the muscular system. Thus, one of the tools recently applied to stimulate the neuromuscular system, reporting positive results in several studies, has been the Mechanical Neuromuscular Stimulation (MNS, vertical vibration platforms). Therefore, we conducted a study with national level competition fencers (n=38, distributed by gender as 12 women and 26 men, and categories as 13 cadets, 12 juniors and 13 seniors), with a protocol of acute exposure to vibration (MNS). We measured the effects produced on the neuromuscular system by means of the analysis of changes experienced in the elective response and movement times, before and after receiving the vibratory stimulus. The protocol chosen was performed by each participant on three occasions: an initial one, another after going through a stimulation load on the vibration platform, and a final phase, after a 10 minute recovery time to assess the degree of dissipation of the vibratory effect. The stimulus chosen on the vibration platform was at a frequency of 50 Hz, for a period of 60 seconds and amplitude of 4 mm. Significant effects were found on the TREPP with 10% reduction on the whole sample and 14,2% in the female fencers.
