Table 2.
All combinations of source, destination, posture, and twist direction that were used in the experiment, along with the number of each that were planned and that actually occurred throughout all 24 experiments. The table is organized by main lifts (the 30 main lifts that we were interested in), extra lifts (lifts designed specifically to serve as transition lifts), and unplanned lifts (lifts that were performed by mistake but do not necessarily hinder results). Though we required 48 occurrences of each of the main lifts (2 of each per participant), some were planned more times as transition lifts for some participants. The extra lifts were only performed when necessary as a transition between 2 main lifts.
