Indirect sinusoidal vibrations induces an acute increase in explosive strength

The purpose of this study was to examine the acute effect of indirect vibration on neuromuscular responses and fatigue resistance (electromyographic activity - EMG and force) during isometric exercise. Nineteen healthy men (age = 22.4 ± 2.7 years; body mass = 76.4 ± 12.9 kg, height = 175 ± 6.7 cm) performed isometric elbow flexion exercises in three experimental treatments: only isometric exercise (control - CON); isometric exercise with the addition of sinusoidal vibrations (SVE1; frequency = 20 Hz, displacement = 3.55 ± 0.5 4 mm); and isometric exercise with the addition of sinusoidal vibrations with frequency variation (SVE2; frequency = 20 ± 3 Hz, displacement = 3.6 ± 0.8 mm).
