Comparative effectiveness of accommodating and weight resistance training modes.

Six men and six women trained the elbow flexors of both arms 3 d.wk-1 for 20 wk. In each training session, one arm did 3-5 sets of 10 maximal concentric actions on an accommodating resistance device (ARD), the other arm 3-5 sets of 8-12 coupled eccentric/concentric actions (repetitions) to volitional failure (8-12 RM) on a weight resistance device (WRD). The average "intensity" (force of concentric actions) was approximately 1.25 times greater …
