| Sumario: | Training using instability devices is common; however, for highly trained athletes, a single device may not provide sufficient challenge. This study examines the effect of superimposed vibration in suspended kneeling rollout. Seventeen physically active participants performed the exercise with non-vibration, vibration at 25 Hz, and vibration at 40 Hz. Muscle activation of the pectoralis clavicularis, pectoralis sternalis, anterior deltoid, serratus anterior, infraspinatus, and latissimus dorsi was recorded during exercise, and the perception of effort was recorded after exercise (OMNI-Res scale). One-way repeated-measures analysis of variance (ANOVA) showed significant differences for the kneeling rollout (p < 0.05). Friedman’s test showed significant differences in the OMNI-Res (p = 0.003). Pairwise comparison showed significant differences in the anterior deltoid (p = 0.004), latissimus dorsi (p < 0.001), infraspinatus (p = 0.001), and global activity (p < 0.001) between the 25 Hz and non-vibration conditions. It also showed significant differences between the 40 Hz and non-vibration conditions for pectoralis sternalis (p = 0.021), anterior deltoid (p = 0.005), latissimus dorsi (p < 0.001), infraspinatus (p = 0.027), and global activity (p < 0.001). The post hoc Conover pairwise comparison showed significant differences in the OMNI-Res only between the non-vibration and vibration at 40 Hz conditions (p = 0.011). Superimposed vibration increases the muscle activation of the upper limbs when performing the suspended kneeling rollout. |
