Figure 2

Exemplar raw force trace for a participant performing an isometric reference contraction at 30° thumb abduction (solid line, Isom), a pure stretch-induced residual force enhancement (dashed line, RFE) and a shortening-stretch cycle in which stretching follors the shortening phase immediately at a 15°/s stretch velocity (dotted line, SSC). The average force (mean 200 ms) before shortening (b-SHO, •), the minimum force at the end of shortening shortening (e-SHO, ■), the maximum force at the end of stretching (e-STR, ▲), and the average isometric steady-state force (500 ms) prior to muscle deactivation.
