Table 1. Participant characteristics and attachment-specific one-repetition maximum values. Variable Enrolled sample (n = 16) Age (years) 20.1 ± 0.9 Body height (m) 1.79 ± 0.05 Body mass (kg) 70.6 ± 5.1 Straight bar 1RM (kg) 76.4 ± 5.7 Wide V-shaped handle 1RM (kg) 69.4 ± 3.6 Cambered bar 1RM (kg) 74.4 ± 5.8 Rope 1RM (kg) 64.4 ± 7.1 Values are mean ± SD. 1RM = one-repetition maximum. Sixteen resistance-trained men were enrolled. Fourteen participants contributed to the primary analyses, and 13-14 participants contributed to the muscle-specific models after surface electromyography (sEMG) data-quality processing.
