Paik, S. H., Yu, C. K., Mermier, C., & Kwon, Y. S. (2014). A descending resistance-training program produces greater exercise volume than a constant resistance-training program. Medicine & Science in Sports & Exercise, 46(5), Supplement abstract number 908.

This study evaluated if a greater training volume (sets × reps × resistance) would be produced using a training protocol where resistance is decreased with each set compared to a constant-resistance protocol in males. To develop the descending set numbers, a S’s fatigue ratio (using an individualized regression equation) from a constant-resistance training protocol was used. Ss completed pre- and post-training volume tests of four sets at 65% and 67% of their 1-RM constant-resistance bench press with 30-second rest periods between sets. During the pre- and post-tests, muscular endurance intensities equivalent to 65% and 67% 1-RM constant- or descending-resistance bench press exercise training were performed for four weeks in counterbalanced order.

There was a greater training volume when Ss trained with descending-resistance sets compared to training with constant-resistance sets after a four-week training period for each condition.

Implication. In males, a greater training volume is attained using a descending-resistance method based on a S’s fatigue ratio than when using a constant-resistance training method.
