Effect of single versus multiple-set resistance training on muscular strength following short-term training. Medicine and Science in Sports and Exercise, 34(5), Supplement abstract 1121.
Untrained Ss (M = 14; F = 33) trained for four weeks as a one set, three sets, or a zero set control group. A 1 RM of supine bench press was used to determine muscular strength before, at two weeks, and at four weeks of training. Training comprised seven repetitions of a supine bench-press with a load of 70-80% 1 RM for one or three sets three times per week.
No group changed to a statistically significant degree, although all improved.
Implication. The training regimen failed to produce significant strength gains in any group over four weeks.
