The effect of visual feedback on enhancing isometric maximal voluntary contractions (MVC) was evaluated. Twelve adults performed plantar-flexion and dorsi-flexion MVCs in 3 conditions (no visual feedback, visual feedback, and visual feedback with target). There was no significant effect of visual conditions on dorsi-flexion MVC but there was an effect on plantar-flexion. Irrespective of whether a target was evident, visual feedback increased plantar-flexion MVC by ∼15%. This study highlights the importance of optimal feedback to enhance MVC.
评估了视觉反馈对增强等长最大自主收缩（MVC）的作用。12名成年人在三种条件下（无视觉反馈、视觉反馈和有目标的视觉反馈）进行了跖屈和背屈MVC测试。视觉条件对背屈MVC没有显著影响，但对跖屈有影响。无论目标是否明显，视觉反馈都会使跖屈MVC增加约15%。这项研究强调了最佳反馈对增强MVC的重要性。
