Avancini, Carolina F. de Oliveira, Liliam L. Menegaldo, Luciano M. Vieira, Taian Regional changes in gastrocnemius architecture with knee position. <p>Mean values and standard deviation (whiskers) are shown for the fat thickness (panel <i>a</i>), the MG fibre length (panel <i>b</i>), and their pennation angle (panel <i>c</i>). These values were obtained from panoramic ultrasound images (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126888#pone.0126888.g005" target="_blank">Fig 5</a>), separately for the proximal (dark, shaded bars) and distal (light, shaded bars) muscle regions. Asterisks denote statistical differences at <i>P</i> < 0.05.</p> knee joint angle;pennation angle;Medial Gastrocnemius Fibres;EMG amplitude distribution;knee position;90 degrees flexion;MG fibre length;fibre length;isometric plantar flexion;MG muscle 2015-05-22
