MAIOR, A. S.; SIMÃO, R.; SALLES, B. F.; MIRANDA, H.; COSTA, P. B. Neuromuscular activity during thesquat exercise on an unstable platform. Brazilian Journal Biomotricity, v. 3, n. 2, p. 121-129, 2009. Thepurpose of this study was to compare the muscular activity of the quadriceps muscles [vastus lateralis (VL),vastus medialis (VM) and rectus femoris (RF)] through surface electromyography (EMG) during the squatexercise with and without the use of an unstable platform (UP). 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 thestudy. Following a specific warm up of two sets of fifteen repetitions (light and moderate load), EMGmeasurements was obtained during the two conditions: maximum voluntary contraction (MVC) on a stablesurface and another MVC on an unstable platform. Three-minute rest intervals between the conditions wereallowed. The Wilcoxon test revealed significantly greater (p < 0.05) muscle activation of the quadricepsmuscles during the squat exercise on the UP (VL = 21%; RF= 18%; VM = 16%). The results of this studyrevealed the UP may be incorporated in some periods of resistance training to increase the activity of thequadriceps muscle. |
