Experimental design for protocols 1 and 2. Following participant preparation, maximum voluntary contraction (MVC) was performed at 0° thumb adduction angle. Stimulation intensity was set to 50–60% of peak MVC force. Protocol 1 and 2 started with force depression followed by the appropriate isometric test. Next, a randomized order of stretch‐shortening cycles (SSC)s with either a (i) varying time interval between stretching and shortening (SSC_0s, SSC_0.5s, SSC_1s; protocol 1) or (ii) varying stretch speeds (SSC_15°/s, SSC_20°/s, SSC_30°/s, SSC_60°/s; protocol 2). Last, an isometric reference contraction at 0° and a MVC were performed to assess fatigue.
