This study investigates between-gender differences in trunk rotational power produced at various loads in athletes of gymnastic and dance sports. A group of 24 female and 15 male competitive aerobic and acrobatic gymnasts, ballroom and rock & roll dancers completed two trials of standing trunk rotations at each side with a barbell of different weights (increasing from 1 kg by ~5 kg up to max. of 20 kg) placed on their shoulders. The power produced during trunk rotations was evaluated using the FiTRO Torso Premium. Results showed significantly higher mean power in the acceleration phase of trunk rotations in male than female athletes at loads of 10.5 kg (206.8 ± 22.0 W and 165.4 ± 17.8 W respectively,
