Values are mean ± SD after averaging retained repetitions within each participant, muscle, attachment, and analytical-interval combination and are expressed as percentages of maximal voluntary isometric contraction (%MVIC). Lifting and lowering denote the cadence-defined analytical windows used for sEMG quantification and should not be interpreted as mechanically synchronized phase boundaries. LD = latissimus dorsi; MT = middle trapezius; PD = posterior deltoid; BB = biceps brachii; TB = triceps brachii; SB = straight bar; WVS = wide V-shaped handle; CB = cambered bar; RP = rope.
