Twenty males (25 ± 3 yrs; 180 ± 5.2 cm; 80 ± 3.2 kg; 24.2 ± 1.6 Kg.m-2) with at least 12 months of experience in resistance training volunteered for the study. Following a specific warm up of two sets of fifteen repetitions (light and moderate load), EMG measurements was obtained during the two conditions: maximum voluntary contraction (MVC) on a stable surface and another MVC on an unstable platform. Three-minute rest intervals between the conditions were allowed. The Wilcoxon test revealed significantly greater (p < 0.05) muscle activation of the quadriceps muscles during the squat exercise on the UP (VL = 21%; RF= 18%; VM = 16%). The results of this study revealed the UP may be incorporated in some periods of resistance training to increase the activity of the quadriceps muscle. 2009 artículo científico 1981-6324 https://www.redalyc.org/articulo.oa?id=93012708004 en http://www.redalyc.org/revista.oa?id=930 Brazilian Journal of Biomotricity application/pdf Universidade Iguaçu Brazilian Journal of Biomotricity (Brasil) Num.2 Vol.3 |
