2. Fig 1
LOS test. Each participant was asked to move the COG as quickly and accurately as possible toward a second target located at the perimeter of the LOSs. The endpoint excursion refers to the distance traveled by the COG on the initial attempt to reach the target.

3. Fig 2
Ankle dorsiflexion angle-torque profiles. On the horizontal axis, negative values represent ankle dorsiflexion, whereas positive values represent ankle plantarflexion. (A) Concentric contraction at 45°/s, (B) concentric contraction at 90°/s, (C) eccentric contraction at 45°/s, and (D) eccentric contraction at 90°/s. The error bars represent one SE of the mean. Between-group difference: *P<.05.

Ankle plantarflexion angle-torque profiles. (A) Concentric contraction at 45°/s, (B) concentric contraction at 90°/s, (C) eccentric contraction at 45°/s, and (D) eccentric contraction at 90°/s. The same convention was used as in figure 1. Between-group difference: *P<.05; †P<.001.
