Our purpose was to verify the effects of the use of the anchors on postural control after the fatigue of the plantar flexor muscles in young and older adults. They stood barefoot, with their eyes closed in four conditions combining the use of the anchors and the fatigue. When using the anchors, participants held one cable in each hand and kept the cable taut without removing the loads (125 g) from the ground. The fatigue protocol consisted of performing a single series of bilateral plantar flexion movements. The fatigue protocol increased postural sway in both groups. Both groups reduced postural sway with the anchors, but this effect was independent of fatigue. We conclude that the anchors contributed to the reduction of postural sway in young and older adults, but they were unable to compensate for the disturbing effect in postural control created by fatigue of the plantar flexor muscles.
我们的目的是验证在年轻人和老年人中，使用固定装置对跖屈肌疲劳后姿势控制的影响。他们赤足站立，在结合使用固定装置和疲劳的四种条件下闭眼。使用固定装置时，参与者双手各持一根缆绳，并保持缆绳绷紧，且不将地面上的负荷（125克）移开。疲劳方案包括进行一系列双侧跖屈运动。疲劳方案增加了两组的姿势摆动。两组使用固定装置后姿势摆动均减少，但这种效果与疲劳无关。我们得出结论，固定装置有助于减少年轻人和老年人的姿势摆动，但它们无法补偿跖屈肌疲劳对姿势控制产生的干扰作用。
