Values are mean ± SD unless otherwise stated and use participants as the unit of analysis. Different superscript letters within a row indicate a statistically significant between-group difference (adjusted p < 0.05).†Welch's ANOVA with Games-Howell post hoc comparisons; other tested continuous variables were analyzed using one-way ANOVA with Tukey HSD comparisons. Prescribed design variables were not tested. Velocity variables summarize 64 working sets per participant. Total working repetitions = mean repetitions per session × 16 and were not separately tested; the 5 calibration repetitions per session were excluded. RPE = rating of perceived exertion.
