Reliability of a simple method for determining muscle fiber conduction velocity

Abstract: The procedures resulted in highly reliable MFCV values, and included: (1) electric identification of motor points prior to electrode placement; (2) twitch identification of muscle fiber orientation to guide initial electrode placement; (3) rotation of electrodes clockwise or counter-clockwise to maximize the similarity and delay of compound muscle action potentials across all detection surfaces; and (4) minimization of synergistic activity during voluntary contractions.

“…The significant force increase exhibited during the retention block was 11.4% greater than the average of the familiarization blocks. The magnitude of strength gain is consistent with previous literature on "quick jumps in strength" as a result of strength assessment alone and not a progressive resistive exercise regimen (Calder and Gabriel 2007;McIntosh and Gabriel 2012). It is generally accepted that strength gains because of a limited number of contractions are associated with a motor learning or "familiarization" effect (Knight and Kamen 2001;Selvanayagam et al 2011).…”

“…Adjustable belts were strapped across the waist and chest to avoid extraneous movement. The participant's right foot was secured on a footplate positioned at 20°of plantar flexion (Feiereisen et al 1997;Marsh et al 1981;McIntosh and Gabriel 2012;McNeil et al 2005). A load cell (JR3 Inc., Woodland, Calif., USA) attached to the bottom of the foot plate recorded force.…”

“…A aceitação da estimativa foi baseada no coeficiente de correlação (r) entre as janelas selecionadas (r > 0,7). Foram descartados valores da VCFM que não estavam dentro da faixa de valores fisiológicos (2-8 m/s) [28]. Por fim, foi calculada a média de todos os valores da VCFM obtidos no período de tempo de 25 s.…”
