    INTRODUCTION: A great number of studies have been conducted lately concerning the use of mechanical vibration as part of the training for improvement of physical conditioning. However, the majority of these studies have evaluated the effects of the exercises joined with the vibrating training in order to determine if there was post-training improvement, and did not evaluate the effects of both vibrating and non-vibrating platform exercises. OBJECTIVE: To evaluate the acute effect of exercise on the knee extensors, with and without the stimulus of the vibrating platform. METHODS: Thirty male active individuals, with age range between 18 and 45 years, randomly conducted three protocols: with the platform on (POG), the platform off (POFFG) and control group (CG). Each protocol began with a five minute warm-up on the ergonomic bicycle, with loads ranging from 75 to 100 watts and 70 rotations per minute, followed by six sets of 10 unilateral squats with one minute of pause between them, with or without mechanical vibrating, and finished with the Work Test, performed only on the dominant leg for determination of the physical valences: work, strength, power and speed. RESULTS: Only the variable speed has presented statistically significant difference (p < 0.05) when the platform on was compared to the control. CONCLUSION: The training on the vibration platform had no influence on the work or muscle power variables, but it exerted negative influence on the movement velocity causing fatigue in the quadriceps muscles.
