| The
analysis included 13 participants and 89 retained repetitions. Durations
were derived from the velocity-based kinematic event algorithm and represent
the active-motion portions of the pull and return. They are distinct from,
and were not intended to reproduce, the complete nominal 2.0-second metronome-prescribed
lifting or lowering intervals. |

Complete-case n = 11. Attachment values are mean ± SD of participant-level mean velocity-defined active-motion durations. GG = Greenhouse-Geisser. Pairwise p values are Holm-adjusted. SB = straight bar; WVS = wide V-shaped handle; CB = cambered bar; RP = rope.
